         <abstract>
            <p>Chronic pain is a widespread issue accompanied commonly by depression and anxiety.
               Chronic pain has been shown to alter brain processing within the emotional and reward
               circuits, pointing towards a possible link between pain and comorbid mood disorders.
               Pain relief may be achieved by alleviating depressive and anxious symptoms.
               Relaxation is important for pain relief and eliciting relaxation through music
               listening is shown to relieve pain, depression, anxiety, and discomfort among others.
               In addition to auditory stimuli, vibroacoustic treatment – the tactile application of
               low frequency sinusoidal sound vibration, plus music listening and therapeutic
               interaction – has been shown to be beneficial for relieving these symptoms. Although
               the combination of music listening and low frequencies has been previously explored,
               the role of the music listening within the vibroacoustic treatment context is
               unknown. A single case, mixed method crossover study was conducted with a client
               suffering from chronic pain and comorbid mood disorders, four sessions with music
               listening, and four sessions without. Quantitative outcomes showed the client was
               more relaxed, less anxious, and had less pain after the music sessions. Qualitative
               findings showed that the client at first could not relax without the music listening
               because of her severe anxiety, later learned to use music as a distractor from her
               thoughts to relax, but also that silence was equally important for her. These hinged
               on her making the choice based on her needs, which had previously been difficult for
               her.</p>

         <title>Introduction</title>
         <p>One in ten adults report chronic widespread pain (<xref ref-type="bibr" rid="MSJJ2016"
               >Mansfield, Sim, Jordan, &amp; Jordan, 2016</xref>). Furthermore, depression and
            anxiety are prevalent in individuals with chronic pain, with these mood disorders
            longitudinally predicting chronic pain and pain-related disability (<xref
               ref-type="bibr" rid="LRBSS2015">Lerman, Rudich, Brill, Shalev, &amp; Shahar,
               2015</xref>). Chronic pain patients may experience maladaptive anxiety and harbour a
            tendency towards hypervigilance or catastrophising their symptoms, often being focused
            on the negative meaning or potential consequences of their pain (<xref ref-type="bibr"
               rid="SF2004">Symreng &amp; Fishman, 2004</xref>). Chronic pain has also been shown to
            alter brain processing, being observed in the emotional and reward circuits, showing a
            possible link between chronic pain and comorbid mood disorders (<xref ref-type="bibr"
               rid="NMXAOP2016">Navratilova, Morimura, Xie, Atcherley, Ossipov, &amp; Porreca,
               2016</xref>). Indeed, reducing depression, anxiety, and pain catastrophising is found
            to relieve pain, and reduce pain-specific disability days and likelihood of disability
               (<xref ref-type="bibr" rid="SKWY2016">Scott, Kroenke, Wu, &amp; Yu, 2016</xref>). Due
            to this interrelation between pain and anxiety, discerning the principle factor may be
            difficult; however, this overlap is fortuitous in treatment as approaches for treating
            one can be beneficial in simultaneously managing the other (<xref ref-type="bibr"
               rid="SF2004">Symreng &amp; Fishman, 2004</xref>).</p>

            <title>Music interventions for relieving pain and mood</title>
            <p>Non-pharmacological interventions that have been beneficial for managing both pain
               and anxiety include those such as paced breathing techniques, muscle relaxation, or
               attention diversion (<xref ref-type="bibr" rid="SF2004">Symreng &amp; Fishman,
                  2004</xref>). Indeed, relaxation has been shown to be an important element in
               relieving pain (<xref ref-type="bibr" rid="EYNMHYASLLW2018">Ezenwa et al.,
                  2018</xref>) and anxiety (<xref ref-type="bibr" rid="NAK2017">Nelson, Adamek,
                  &amp; Kleiber, 2017</xref>) and as musical experiences (e.g. music making such as
               singing or listening to pre-recorded music) elicit and evoke emotional responses in
               us, they are often used to regulate emotions (<xref ref-type="bibr" rid="LN2011"
                  >Lonsdale &amp; North, 2011</xref>) but also for the purpose of pain relief (<xref
                  ref-type="bibr" rid="TC2016">Tamplin &amp; Clark, 2016</xref>).</p>
            <p>Music interventions have been shown to be efficacious at relieving anxiety,
               depression (<xref ref-type="bibr" rid="LLL2012">Lai, Li, &amp; Lee, 2012</xref>),
               pain, and inducing a state of relaxation (<xref ref-type="bibr" rid="LP2015">Liu
                  &amp; Petrini, 2015</xref>). It is proposed music may act as a distractor from
               patients’ psychological and physiological sensations as well as reducing patients’
               experiences of discomfort (<xref ref-type="bibr" rid="N2008">Nilsson, 2008</xref>) by
               serving as an audioanalgesic, audioanxiolytic, or audiorelaxant, as well as music
               listening having an effect on hospital patients’ stress responses (<xref
                  ref-type="bibr" rid="N2009">Nilsson, 2009</xref>). A systematic review (<xref
                  ref-type="bibr" rid="BDS2013">Bradt, Dileo, &amp; Shim, 2013</xref>) found that
               music listening might be beneficial for reducing anxiety in people with myocardial
               infarction, also indicating that music listening may reduce pain. Although music as a
               distractor is an important mechanism in anxiolytic responses (<xref ref-type="bibr"
                  rid="N2008">Nilsson, 2008</xref>), <xref ref-type="bibr" rid="BDS2013">Bradt et
                  al. (2013)</xref> argued that music also affords an aesthetic experience, able to
               offer comfort, and creative engagement in music may result in an increase in
               perceived control. In a surgical setting, Wu, Huang, Lee, Wang, and Shih (<xref
                  ref-type="bibr" rid="WHLWS2017">2017</xref>) reported significantly reduced anxiety
               for patients undergoing an awake craniotomy after listening to their preferred music.
               Although Gillen, Biley, and Allen (<xref ref-type="bibr" rid="GBA2008">2008</xref>)
               found that anxiety reduction from music listening seems to be more strongly reflected
               in the psychological parameters (e.g. State-Trait Anxiety Inventory) rather than
               physiological markers of anxiety and stress (e.g. heart rate), the aforementioned
               overlap between the physiological and psychological aspects of pain and
               anxiety/depression points towards a cumulative intervention effect. This may be
               important in designing interventions for patients suffering from these psychological
               and physical symptoms. Results of studies presented here seem to generally suggest
               consistently positive and significant reduction in anxiety and pain due to music
               intervention, as well as increased relaxation and decreased depression.</p>

            <p>Music interventions can also be delivered in a tactile manner such as with pulsed,
               sinusoidal, low frequencies between 20–120 Hz through a recliner chair or mattress
               combined with music listening and therapeutic interaction. When applied by a trained
               practitioner, these combined elements (see Figure 1) are referred to as Vibroacoustic
               (VA) treatment (<xref ref-type="bibr" rid="CHAR2017">Campbell, Hynynen, &amp;
                  Ala-Ruona, 2017</xref>). Low frequencies may also be delivered without music
               listening, based on the client’s needs and preferences, e.g. music may evoke memories
               or sensations which the client is not yet ready to address. The rationale for
               listening to music is therefore based on whether the music listening may enhance the
               experience for the client. For those who enjoy music, it may more readily enable
               relaxation and offer a source of comfort.</p>

            <p>As is often the case for music listening, relaxation is one of the most commonly
               reported outcomes of VA treatment (<xref ref-type="bibr" rid="ARPC2015">Ala-Ruona,
                  Punkanen, &amp; Campbell, 2015</xref>; <xref ref-type="bibr" rid="CHAR2017"
                  >Campbell, Hynynen, &amp; Ala-Ruona, 2017</xref>). The relaxation response, a
               relaxed but alert state elicited through repeated and focused meditative practices
                  (<xref ref-type="bibr" rid="B1975">Benson, 1975</xref>), is posited to be one
               possible explanation for the positive outcomes associated with this treatment
               modality (<xref ref-type="bibr" rid="PAR2012">Punkanen &amp; Ala-Ruona, 2012</xref>).
               Recent studies focusing only on the pulsed sinusoidal low frequency sound vibration,
               i.e. without music listening or therapeutic interaction, have shown that low
               frequencies are beneficial for pain relief and mood regulation (<xref ref-type="bibr"

                  >Rüütel, Ratnik, Tamm, &amp; Zilensk, 2004</xref>), spasticity in those with
               spinal cord and brain injuries (<xref ref-type="bibr" rid="RVE2017">Rüütel, Vinkel,
                  &amp; Eelmäe, 2017</xref>), can be beneficial for decreasing both pain and stress,
               and increasing emotional enrichment, concentration, and physical and emotional
               relaxation (<xref ref-type="bibr" rid="ADK2012">Ahonen, Deek, &amp; Kroeker,
                  2012</xref>) as well as reducing anxiety and affording relaxation in those with
               Alzheimer’s disease (<xref ref-type="bibr" rid="CCFB2017">Clements-Cortés, Ahonen,
                  Freedman, &amp; Bartel, 2017</xref>). Campbell, Hynynen, and Ala-Ruona (<xref
                  ref-type="bibr" rid="CHAR2017">2017</xref>) showed improvements in pain, mood, and
               relaxation for those receiving the combined treatment of low frequencies and music
               listening with therapeutic interaction. Skille and Wigram (<xref ref-type="bibr"
                  rid="SW1995">1995</xref>) compared the effects of music plus vibroacoustic
               stimulation (40 and 55 Hz) to music alone for those with multiple physical
               disabilities, finding that vibroacoustics was beneficial in reducing muscle tone and
               increasing range of motion. Wigram (<xref ref-type="bibr" rid="W1996">1996</xref>)
               compared new age music listening, vibroacoustics (40 Hz), and lying in silence with
               non-clinical participants and found reduced arousal in the vibroacoustic group
               compared to both the music and control group. Both vibroacoustics and music groups
               had reduced heart rate compared to the silence group. Rüütel (<xref ref-type="bibr"
                  rid="R2002">2002</xref>) also examined the effects of music, vibroacoustics,
               and silence on healthy people, finding that one or two sessions of vibroacoustics
               were beneficial for reducing fatigue or stress for healthy people in everyday
               life.</p>
            <p>These studies have examined the effects of low frequencies alone, the combination of
               all three VA treatment elements, as well as comparing the effects of low frequencies
               with and without music. However, the role that music listening plays in the treatment
               session with therapeutic interaction has not been explored. As discussed, music
               listening has been shown to be efficacious at inducing a relaxed state and relieving
               pain, anxiety, and depression. Low frequency vibration has also been shown to do so,
               as has the combination of music listening, low frequencies, and therapeutic
               interaction. Given that both music and vibration can be beneficial for symptom
               relief, the aim of this study was to explore in more detail the role that the music
               listening element within a practitioner-supported VA treatment setting may have with
               a client suffering from chronic pain, anxiety, and depression. Furthermore, this
               study investigates whether the client’s perception and experience of her symptoms -
               and the influence VA treatment has thereon - are enhanced by music listening.</p>

            <p>A mixed method, n-of-1 crossover design was used to explore the role of music in VA
               treatment, integrating quantitative and qualitative data to triangulate the results
               and findings to gain a greater understanding of these subjective physical and
               psychological phenomena. Although quantitative methods are helpful when addressing
               the relationship between specific variables, they are not suitable for answering
               process-oriented questions that can be addressed using qualitative approaches (<xref
                  ref-type="bibr" rid="LO2007">Leech &amp; Onwuegbuzie, 2007</xref>). Triangulation
               of mixed methods is used to describe an issue (e.g. pain) from several perspectives
               to gain a more complete impression of the phenomenon (<xref ref-type="bibr"

               the quantitative data can shed light on a patient’s change (e.g. potential
               improvement) during the therapeutic process, whilst the qualitative data may be used
               to understand the sudden fluctuations on the symptoms represented in the quantitative

            <title>Participant</title>
            <p>Jane was a 34-year-old mother of two living with her partner who was on disability
               sick leave. She first took leave in 2008 due to burnout and then due to surgery for a
               herniated disc in 2012 after a brief return to work. She had moderate depression,
               panic disorder and anxiety, difficulty relaxing and sleeping, stress, tension
               headaches, migraines, and shoulder pain, although there was no organic reason for
               these symptoms. The lack of discernible medical explanation for her collection of
               symptoms may be grouped under the term Medically Unexplained Symptoms (MUS). This
               includes musculoskeletal pain and ‘pseudoneurology’ – tiredness, sleeping issues,
               fatigue, and mood changes (<xref ref-type="bibr" rid="EU2004">Eriksen &amp; Ursin,
                  2004</xref>). Although unexplained, these symptoms have, in addition to headaches,
               high blood pressure, and emotions such as anger, anxiety, and panic, been linked to
               negative stress (<xref ref-type="bibr" rid="YS2011">Yehuda &amp; Seckl, 2011</xref>)
               such as from shock. She explained she would like to move forward with her life but
               was feeling stuck. Once or twice per month, Jane visited her local healthcare centre
               and spoke with the psychiatric nurse. She did not take any medication, except for
               analgesics when migraines were particularly severe. She had applied to participate in
               music therapy as part of clinical training at the Music Therapy Clinic for Research and Training at the University of Jyväskylä, Finland, and due to the severity and
               collection of symptoms, was approached by EAC regarding her willingness to
               participate in VA treatment instead of music therapy for managing pain and comorbid
               symptoms. The research was conducted at the music therapy clinic and therefore followed the general
               principles and rules of therapeutic work at healthcare units. She gave informed
               consent to have weekly sessions and to publish her experiences of the process.</p>

            <title>Procedure</title>
            <p>Vibroacoustic (VA) treatment consists of three elements: pulsed sinusoidal low
               frequency sound vibration (20-120Hz), (client preferred) music listening, and
               therapeutic interaction between client and practitioner (<xref ref-type="bibr"
                  rid="CHAR2017">Campbell, Hynynen, &amp; Ala-Ruona, 2017</xref>; <xref
                  ref-type="bibr" rid="ARP2017">Ala-Ruona &amp; Punkanen, 2017</xref>). The music
               listening and low frequency sound vibration are received simultaneously. The sound
               vibration is transmitted through devices such as chairs, cushions, or mattresses
               whilst the music listening is typically delivered through headphones. In general, the
               procedure is conducted in several stages: preparation for the session (setting up the
               equipment), introducing the client to the treatment modality, beginning the combined
               sound vibration and music listening, monitoring the client’s reception, ending the
               stimulus, and post-stimulus work (e.g. processing) (<xref ref-type="bibr"
                  rid="GW2007">Grocke &amp; Wigram, 2007</xref>). The therapeutic relationship
               between the client and practitioner may take the form of verbal interaction between
               the client and practitioner, usually before and after the low frequency sound
               vibration and music listening. However, in some cases, the client may wish to
               interact with the practitioner during the stimulation. A client may fall asleep
               during the stimulus and the practitioner’s role thereafter is to reassure and guide
               the client back to the present moment. Before and after the stimulus, the
               practitioner plays an important role in experiential processing. This may take the
               form of offering comfort and helping the client to process and reflect on experiences
               and sensations.</p>
            <p>The VA treatment procedure in this study was as follows: 10 VA treatment sessions
               were planned with the client (hereafter referred to as ‘Jane’) to take place once per
               week in a single case crossover design of Vibroacoustic sessions with (VA-Music) and
               without (VA-Silence) music listening. Jane wore headphones in all sessions, but no
               music was played during VA-Silence sessions. Before the first session, the
               practitioner asked Jane to send a list of her preferred music listening choices. Jane
               suggested some artists to which she sometimes listened and the practitioner made a
               playlist based on these suggestions. The VA sessions took place in a music therapy
               clinic equipped with a Next Wave Physioacoustic recliner chair (Next Wave, n.d.). The
               client lay in a supine position on this chair with a blanket during all sessions and
               the lights were dimmed during the low frequency stimulation. The same 20-minute low
               frequency programme (ranging from 29—61 Hz) was used in all sessions; this frequency
               range has been beneficial for managing physical and psychological disorders and
               inducing relaxation (<xref ref-type="bibr" rid="CHAR2017">Campbell, Hynynen, &amp;
                  Ala-Ruona, 2017</xref>).</p>
            <p>The client received eight sessions in total; two sessions were cancelled due to
               illness. Four sessions (S1, S3, S5, S6) comprised usual protocol for VA treatment:
               low frequency sound vibration, music listening, and therapeutic interaction
               (VA-Music). Four sessions (S2, S4, S7, S8) comprised all of these elements minus
               music listening (VA-Silence). It was planned that every second session would be
               VA-Silence, however this change in scheduling was made for therapeutic reasons
               (discussed in sections <italic>Control through choice </italic>and <italic>Music as a
                  translational mechanism</italic>).</p>
            <p>Sessions 1 and 2 focused on preparing Jane for the procedure and becoming accustomed
               to the sensation of low frequencies and discussing her difficulty with relaxation in
               general. Sessions 3-5 focused on how Jane could become more aware of her physical
               sensations as a way to anchor her in the present moment. She was also paying
               attention to the effects of the treatment and beginning to integrate these changes
               into her daily life. Sessions 6 and 7 were about making choices for her regarding
               self-care (e.g. taking medication, receiving massage) and noticing other changes
               outside the sessions. The final session further explored making choices and how the
               effects of the sessions may be translated into daily life, and expressing a
               willingness to continue to try and help her.</p>

            <title>Outcomes assessment</title>
            <p>The data for this study consisted of both qualitative and quantitative measures. The
               qualitative data were transcribed discussions between Jane and Practitioner, whilst
               the quantitative data comprised Visual Analogue Scales (VASs). A VAS is a
               unidimensional self-complete scale composed of a horizontal 100mm line with two
               verbal descriptors on either end (<xref ref-type="bibr" rid="HMKF2011">Hawker et al.,
                  2011</xref>). The scales used in the present study assessed pain (VAS-P), mood
               (VAS-M), anxiety (VAS-A), and relaxation (VAS-R) and were completed by Jane before
               and after each 20-minute treatment programme in each session. The anchors for these
               scales were: 0 (<italic>worst pain imaginable</italic>) to 100 (<italic>no
                  pain</italic>); 0 (<italic>depressed</italic>) to 100 (<italic>happy</italic>); 0
                  (<italic>very anxious</italic>) to 100 (<italic>no anxiety</italic>); and 0
                  (<italic>tense</italic>) to 100 (<italic>relaxed</italic>) respectively. At all
               VAS measurement points, Jane was asked to mark each scale to represent her current
               state at that moment, thereby enabling an assessment of both within- and
               between-session change. Visual Analogue Scales are widely implemented in diverse
               populations due to low respondent burden and ease of administration (<xref

               <title>Quantitative data analysis</title>
               <p>The pre- and post-treatment VAS outcomes were analysed using SPSS (IBM SPSS
                  Statistics, Version 24). Both an overview of the process as well as a comparison
                  between each condition are presented. The pre-treatment score in Session 1 and the
                  post-treatment score in Session 8 for each variable are used to give an overview
                  of the between-session therapeutic process. Additionally, the mean (and standard
                  deviation) pre- and post-treatment pain, mood, anxiety, and relaxation scores for
                  both VA-Music and VA-Silence conditions are presented to show within-session
                  change. Guidelines for interpreting quantitative outcomes such as VASs are
                  beneficial to understand patients’ responses to interventions. <xref

                  as the minimal clinically important difference (MCID) and for VAS-P has been
                  defined as 10-20% as MCID, &gt; 30% as moderate improvement, &gt; 50% as

               <p>Patients’ experiences and the corresponding disability or
                  <italic>ill</italic>-being resultant of chronic pain are important in further
                  delineating the efficacy of chronic pain management treatment methods.
                  Understanding how a client engages in meaning-making and the elements of a
                  subjective experience which they consider important give insight into the
                  experience of suffering and alleviation thereof. To this end, interpretative
                  phenomenological analysis (IPA) allows researchers to gain insight into what is
                  important to participants, then exploring what this <italic>means</italic> to them
                     (<xref ref-type="bibr" rid="SO2007">Smith &amp; Osborn, 2007</xref>). Situating
                  and understanding a participant’s experiences and meaning making can help to
                  interpret findings from quantitative outcomes (<xref ref-type="bibr" rid="LT2011"
                     >Larkin &amp; Thompson, 2011</xref>). Thus, IPA was used in this study to gain
                  greater insight into the meaning of music within her VA treatment process.</p>
               <p>The analytic process was as follows. The transcripts from all sessions were read
                  and re-read several times to obtain a sense of the participant’s experiences.
                  Several coding methods were used. The first coding round consisted of descriptive
                  coding, in addition to emotion coding, process coding, conditional coding, and
                  evaluation coding. Descriptive coding highlighted Jane’s experiences throughout
                  the process, whilst process coding showed what happened to the participant
                  throughout this process; emotion coding highlighted all emotion words used by the
                  participant; conditional coding was applied to structures such as ‘if…then’, to
                  find connections between conditions and actions/outcomes, and finally evaluation
                  coding was applied to see how the participant evaluated each
                  condition/intervention. These codes were primarily organised into themes and then
                  explored for interrelationships (<xref ref-type="bibr" rid="S2009">Saldaña,
                     2009</xref>), with a focus on Jane’s overall response to the VA treatment
                  sessions and then paying attention to how she responded to the VA-Music and
                  VA-Silence sessions separately. Themes that clustered together were grouped as
                  superordinate themes (<xref ref-type="bibr" rid="OS1998">Osborn &amp; Smith,
                     1998</xref>; <xref ref-type="bibr" rid="SO2007">Smith &amp; Osborn,
                  2007</xref>). The emergent themes were organised such that a consistent and
                  meaningful representation of Jane’s experiences were presented, representing the
                  essence of her responses to the treatment and the factors potentially influencing
                  this response. The analysis thus followed an inductive rather than deductive
                  approach, establishing themes from the data rather than from pre-determined
                  constructs.</p>

               <p>After both qualitative and quantitative outcomes were analysed separately by
                  EAC, the results and findings of each were co-explored and are presented
                  narratively and visually, highlighting the quantitative responses to each
                  treatment modality and discussing the qualitative findings supporting these
                  outcomes. The role of the VASs was to gain insight into the potential influence of
                  VA sessions with and without music listening on pain, mood, anxiety, and
                  relaxation, however as these are subjective phenomena, the participant’s
                  subjective experiences of the treatment – as well as her state in between sessions
                  – was important in bringing greater understanding to how the treatment process
                  affected her. The verbal processing within the treatment sessions, and later in
                  the member check interview, afforded her the possibility to explore and share her
                  own experiences (<xref ref-type="bibr" rid="BPKSRSGKK2015">Bradt et al.,

            <title>Member check</title>
            <p>To assess the validity of the analysis, a member check interview – otherwise referred
               to as a validation interview – was conducted with Jane to discuss the emergent themes
               and their genesis based on the transcripts, and to “confirm, substantiate, verify or
               correct researchers’ findings” (<xref ref-type="bibr" rid="B2011">Buchbinder,
                  2011</xref>), i.e. to
               discuss whether the themes presented accurately represented the discussions and her
               experiences during the treatment process. In the interview, EA-R presented both
               quantitative results and the qualitative findings to assess if these were accurate
               representations of her experience during the process or not, whether she wished to
               add something to the outcomes which she felt was important, or whether there were
               aspects she wished to correct in the results and findings to better portray the
               sessions. (EAC’s role in this process is discussed in the subsequent section.)
               Conducting the member check interview – termed as descriptive triangulation – in
               which the researcher(s) show the findings or interpretations to the participants in
               order to assess accuracy, was a means of increasing trustworthiness of the
               qualitative findings (<xref ref-type="bibr" rid="LO2007">Leech &amp; Onwuegbuzie,

               <title>Roles of the researchers / practitioner</title>
               <p>The authors played various roles in the therapeutic process as well as the data
                  collection and analysis phases. During the treatment process, EAC filled the
                  roles of both practitioner and researcher. She met with the client to discuss
                  the procedure of the sessions, acquired informed consent from Jane, and collected
                  the data at the beginning and end of each session. In the practitioner role,
                  EAC facilitated the therapeutic process, delivering the music and tactile
                  interventions at each session. A number of clinical researchers subscribe to the
                  idea that research in itself, as well as follow-up interviews, has a therapeutic
                  effect (<xref ref-type="bibr" rid="SW2006">Sandahl &amp; Wilberg, 2006</xref>).
                  From this perspective, the interacting and overlapping roles of a practitioner and

               <p>Both EAC and EA-R conducted the member check interview. Although it was

                  requested that EAC also be present in the meeting. EAC’s role was
                  passive in the member check interview unless clarification was needed and

            <p>When viewing the overall process, Jane recorded clinically relevant pain decrease and
               relaxation increase were when only the pre- treatment score from Session 1 and the
               post-treatment score from Session 1 are presented (i.e. both VA-Music and VA-Silence
               sessions). At the end of the process, her pain corresponded to <italic>no
                  pain</italic> and relaxation corresponded to <italic>mild tension </italic>when
               following the interpretation guidelines (<xref ref-type="bibr" rid="JCB2003">Jensen
                  et al., 2003</xref>). Mood and anxiety deteriorated during this time to a minimal
               clinically relevant degree (see Table 1). Both mood and anxiety were <italic>moderate
               </italic>at the end of the treatment process.</p>
            <p>When comparing the mean VAS outcomes between the music and silence sessions, VAS-M,
               VAS-A, and VAS-R showed improvement; VAS-P change was negatively clinically relevant
               change in the silence sessions, but showed improvement in the music sessions,
               indicating that music was at least somewhat beneficial for pain. VAS-M improvement
               was clinically relevant in the music sessions, but VAS-A and VAS-R were substantially
               clinically relevant in both conditions according to the MCID (see Table 1). These
               results indicate that the VA-Music sessions were more beneficial for anxiety and
               relaxation than for pain or mood.</p>

            <p>VA-Silence pre-treatment scores were generally better compared to VA-Music, as the

               and for VA-Music was in the <italic>mild </italic>category. From an individual
               session perspective (see Figure 2), substantial improvement was recorded in Sessions
               3 (VA-Music), with MCID in Session 5 (VA-Music). MCID negative change was
               reported in Sessions 1 and 6 (VA-Music) and Sessions 2, 4, and 7 (VA-Silence). There
               was relatively high variation between the conditions; however, when the pre-treatment
               score was the worst (Session 3), the improvement was also the most substantial.</p>

               sessions, moderate improvement was reported in Session 4, clinically relevant
               improvement in Session 7 but negative clinically important change in Sessions 2 and
               8. Therefore, although the final score at the end of the process was worse than the
               beginning of the process, the mean change over time was nevertheless towards
               improvement, although only clinically relevant for the VA-Music sessions.</p>

               Qualitative findings</title>
            <p>Jane’s experiences of VA treatment and the role that music played in this process
               were explored in the interaction between her and the practitioner during the eight VA
               sessions. Three superordinate themes emerged from the analysis: <italic>Trapped by
                  her anxiety, Control, </italic>and <italic>A changing self-reflection</italic>;
               the interrelationships of these themes are shown in Figure 6. Each
               superordinate theme had subthemes, which are presented narratively with exemplative
               quotations. The first two superordinate themes were interconnected – Jane sought
               control as she was trapped by her own anxiety – and the second and third
               superordinate theme were interconnected – Jane began to see changes by using music
               listening as a means to take control in a different way. The
               interrelationships of these themes are represented in the figure such that Jane’s
               anxiety and need for control were pervasive and connected to each other. Being
                  <italic>Trapped by her anxiety</italic> overlapped with her need to control all
               situations, yet her anxiety and need for control were starting points in the process
               and are therefore stacked rather than linear as both themes were equally prevalent.
               The superordinate theme <italic>A changing self-reflection </italic>is justified to
               the right as it signifies the process of moving forward, rather than the stagnation
               of being trapped by one’s emotions. It overlaps with <italic>Control </italic>because
               Jane was nonetheless struggling to make this change, but was able to try with the
               help of the VA treatment sessions.</p>

            <title>Trapped by her anxiety</title>
            <p>Jane was unable to relax at home – she sometimes found solace wandering the shops and
               could relax there because she was alone and it was quiet; she described her attempts
               to relax at home as “<italic>chaos.”</italic> She equated this chaotic feeling with
               the inability to relax during her first VA-Silence session: “But it is the same if
               I’m at home and I try to relax and I have that same kind of feeling as now without
               the music<italic>.</italic>” She felt trapped in feelings from which she could not
               escape, her health situation, and being so sensitive to each sensation she felt
               caused her great distress: “It’s too distressing…I feel as though I am in a box and I
               can’t get out of it.”</p>

               <title>Unable to escape her own thoughts</title>
               <p>She tried to consciously avoid thinking about situations that gave her anxiety –
                  such as her daughter wishing to move in with her biological father – and admitted
                  that this in turn increased the sensation:</p>
               <disp-quote>
                  <p>If I don’t think about those things consciously, about my daughter and my
                     health, then they just circulate in my mind and I think about them in the
                     evening and I get that kind of feeling…and I think it’s exacerbated by
                     that.</p>

               <p>Jane found in Session 2 (VA-Silence), that she had no distraction from her
                  thoughts in the absence of music: “Somehow I wasn’t able to relax; I was thinking
                  the whole time, and there was nothing else. ”She found her
                  thoughts were initially much more relaxed with music than without (Session 3): “My
                  mind was much more peaceful than without music, even though I wasn’t necessarily
                  listening to the lyrics, but still somehow…it was relaxing!”</p>
               <p>In addition to this, Jane had no resources to alleviate her anxiety. This led to
                  her suppressing her emotions even further, creating a space in which she had no
                  escape from her anxiety: “I don’t have the resources to take the anxiety away or
                  reduce it. Maybe it would be better if I just spoke about it, but who can I talk
                  to? Talking to yourself isn’t fun!” She recognised her need to talk as a means to
                  understand and process her situation, yet this was problematic. She was alone in
                  her suffering; she had only one friend, whom she seldom met. This meant that she
                  could not offload and it caused her to spiral into unhealthy patterns of
                  rumination. She was highly aware of this fact: “If I can’t speak to someone about
                  it then I don’t think rationally and there’s uncertainty.”</p>

               <title>Trying to self-help</title>
               <p>When attempting to rectify this and speak to a friend to relieve her anxiety, she
                  was unable to prioritise her own feelings, again trapping herself in this anxious
                  space; after making plans to meet during the day and then to watch a film together
                  in the evening, Jane received a message from her friend cancelling the earlier
                  meeting: “I was disappointed that we couldn’t meet during the day because then we
                  can’t talk. ”When asked whether she could have told her friend
                  that it was important, it became clear that her own feelings were not a priority:
                  “I could have written that it’s very important, but what can I do if she’s feeling
                  really bad and she just can’t make it to meet during the day? ”Additionally, Jane expressed that she had expected such a cancellation
                  message; it was almost a self-fulfilling prophecy in not expressing this to her
                  friend. Instead, she suppressed rather than expressed her anger.</p>
               <p>Although she was trapped in her anxiety, Jane was also seeking out ways to help
                  herself. She did not find the visits with the psychiatric nurse beneficial and did
                  not want to take mood regulators as “it kills something [inside you] when you take
                  that…I don’t like taking medications.” Despite gaining no use from the visits, she
                  still went once per month; she was afraid to give these up, having a strong desire
                  to improve her situation. She felt desperate with her own emotions and sought out
                  methods to help herself, including complementary medicine, avoiding interventions
                  with which she had previously had negative experiences i.e. pharmacological mood
                  regulators.</p>

               <p>In addition to being in an almost constant state of emotional upheaval, she was
                  also acutely and constantly aware of physical sensations in her body, having pain
                  and tension every day, immediately attributing new sensations to a new health
                  concern: “Now, I’m always afraid of what it [new pain] is.”</p>

            <title>Control</title>
            <p>She admitted that she found it difficult to be out of control of a situation:
                  ‘<italic>I’m that kind of person that needs to always know what is happening
                  next</italic>’<italic>. </italic>This stemmed from the sudden need for surgery
               after a herniated disc and as a result being afraid of each sensation she felt,
               anxious that it may lead to something more serious: ‘<italic>I worry about what’s
                  coming. It’s pretty hard</italic>’<italic>. </italic>She also felt unable to
               control her own thoughts and incapable of calming herself down. During the process,
               she was awaiting a phone call from her doctor with results from a scan. She explained
               that she felt extremely anxious the night before the expected phone call and was
               unable to relax. Nevertheless, she felt that she was lucky that she had not been
               worrying the whole week, suggesting that she felt her anxiety was out of her control:
                  ‘<italic>Luckily I didn’t worry before</italic>’.</p>

               <title>Control through choice</title>
               <p>Although Jane expressed that she felt the need to constantly be aware of what was
                  coming and be in control, she also seemed to fear this control. This manifested in
                  her difficulty to make choices for herself. During a scheduled VA-Silence session,
                  Jane asked to listen to music, asserting her need for distraction. This moment of
                  choice was important, as asking for something she needed was difficult for Jane;
                  it showed she could control her affect regulation when really needed. As this
                  choice had been important, the practitioner asked Jane in a later session whether
                  she wished to listen to music or not, offering her the choice based on her needs;
                  although she was eventually able to make the decision (deciding on silence), and
                  afterwards felt it was good there was no music, she found it hard to make the
                  choice.</p>

               <title>A changing self-reflection</title>
               <p>After the first session (VA-Music), Jane felt ‘<italic>just wonderful</italic>’
                  and spent six to seven hours shopping after the treatment; thereafter, she noticed
                  how tired she was. She was surprised by her ability to relax during the first
                  session of trying something new: ‘<italic>This mode worked surprisingly … for the
                     first time…surprisingly well</italic>’<italic>, </italic>but she was not able
                  to pace herself after the session and was fatigued after spending hours walking
                  around the shop. Interestingly, although she felt physically relaxed afterwards,
                  her mind was still very active throughout the stimulation; she was quite anxious,
                  spending the entirety of the treatment programme counting the songs to figure out
                  how long was left: ‘<italic>Always thinking about what song is next – calculating
                     now three minutes, and one song is almost four minutes and now it’s been eight
                     minutes</italic>’<italic>.</italic>
               </p>
               <p>Initially, she responded poorly to the VA-Silence sessions. She found her mind was
                  much more restless without music as she had nothing with which to distract
                  herself: ‘<italic>My mind was much more agitated without music. … The thoughts
                     lasted the whole time, it was terrible, it wasn’t good, no, no, just
                     terrible</italic>’<italic>. </italic>She found it difficult to be in the
                  sessions without music and was overwhelmed by it. She felt that, even if she does
                  not listen to the lyrics of the songs, she could choose when to listen to the
                  music and when to let her mind wander and this relaxed her: ‘<italic>At the same
                     time I can think and then I can listen again to the singing</italic>’. This
                  became a technique for her during VA-Music sessions; selective listening became a
                  way for her to self-regulate her anxious thoughts.</p>

               <title>Struggling to adjust to change</title>
               <p>Jane’s symptoms were relieved from the treatment, she found that she was able to
                  think more clearly, and expressed having a ‘<italic>free
                     feeling</italic>’ after leaving each session. This
                  improvement, however, also sparked anxiety. She feared what would happen in the
                  Autumn when the darkness would return and she would no longer have VA treatment
                  sessions, again alone in her suffering. She expected to feel worse again and for
                  the improvements to be only fleeting. Unable to enjoy the improvement, she
                  hampered the sensation, instead worrying about the future. She was not able to
                  adjust to the positive change, instead stuck in the feeling that her symptoms
                  would not remain away. Despite this worry about the future, she remarked in
                  Session 7 that she had not had pain or tension in the previous two weeks and she
                  also felt that her frame of mind was better: ‘<italic>Sometimes I think I
                     </italic>think<italic> better</italic>’. Although struggling to adjust to the
                  change, she also acknowledged that she was experiencing relief and she was
                  beginning to pay attention to the positive rather than worrying about negative
                  feelings she experienced.</p>

               <title>Music as a translational mechanism</title>
               <p>Music changed the way Jane perceived the treatments; the sensation of the VA
                  treatment programme was different depending on whether she was listening to music
                  or not. The music distracted her both from her own thoughts but also translated
                  the sensation of the vibrations so they felt less intense, although the same
                  frequency series was used each time. She felt that the treatment programme went by
                  more quickly with music and that the vibrations moved up and down her body
                  differently, sensing them in different parts of her body when she listened to
                  music (moving from legs towards chest) compared to no music (chest area, no
                  movement).</p>
               <p>Music also translated the way Jane felt about silence. Although she was at first
                  afraid of the sessions without music, she later found that the silence was an
                  important element for her, too, and that actually she needed the silence when she
                  was in a highly aroused state. She was anxious and upset about her daughter
                  wishing to move in with her biological father; Jane recognised that her previously
                  having used music as a way to distract herself from her anxiety did not apply at
                  this point and, music was not something she needed at this time. She did not
                  desire an escape from her anxiety and felt that listening to music would be too
                  overwhelming for her. Although she did not feel relaxed after the session, she
                  felt that ‘<italic>it was good there was no music</italic>’. This was a stark
                  contrast to her initial fear of silence. Her choice to not listen was an important
                  step in her process and made her realise that she did not need to have music to
                  distract her all the time, rather could selectively use it when she felt she
                  needed support, feeling in control of her fear of silence: ‘<italic>I think I beat
                     my fear</italic>’. This mirrored what she did during the VA-Music sessions,
                  during which she chose to selectively listen to the music and channel it when she
                  felt the need.</p>

            <title>Integrated results</title>
            <p>Both quantitative and qualitative outcomes of this study showed that Jane was in a
               state of suffering. Throughout Jane’s process, it was possible to see her move
               through an isolated and anxious state of suffering towards the hopeful understanding
               of the possibilities that music offered her in symptom management and in showing her
               that it is possible to relieve her anxiety. She displayed how one may struggle to
               cope but also how VA treatment can be used to help retrain one’s focus from negative
               sensations towards developing a sense of self-efficacy, making choices based on her
               own needs.</p>
            <p>The findings revealed that anxiety had control over Jane’s ability to engage in daily
               activities, which was sometimes overwhelming; her need for control in general was
               magnified when she felt out of control of her own thoughts. She began to take small
               steps towards discovering and enacting her own needs and this was highlighted at the
               pivotal stage of choosing to first have music in Session 6 and then not in Session 8.
                  <italic>Control</italic> was overlapping both her struggles with anxiety and her
                  <italic>changing self-reflection</italic>, and the means of taking control for her
               was to utilise the music listening to regulate her anxiety within music sessions when
               needed, but also to choose when not to listen to music. Music affected her during the
               process by enabling her to make this choice and increase her sense of control. Bradt,
               Dileo, and Shim (<xref ref-type="bibr" rid="BDS2013">2013</xref>) also found that
               engaging in music can increase the perception of control. During the first VA-Silence
               session (Session 2), pain, mood, anxiety, and relaxation got worse; this negative
               reaction was supported by her verbal processing of the experience (‘<italic>My mind
                  was much more agitated without music. … The thoughts lasted the whole time, it was
                  terrible, it wasn’t good, no, no, just terrible</italic>’). In the next session
               (VA-Music), Jane reported substantial improvements in pain, anxiety, and relaxation,
               and moderate improvement in mood with the VASs, and also verbally reported as such
                  (‘<italic>My mind was much more peaceful than without music, even though I wasn’t
                  necessarily listening to the lyrics, but still somehow…it was
               relaxing!</italic>’). Jane’s perception of being calmer during VA-Music sessions is
               also represented in the mean outcomes per condition (i.e. VA-Music vs VA-Silence), as
               mean improvement for anxiety was substantial in VA-Music sessions, yet substantial
               improvement was clear for relaxation in both VA-Music and VA-Silence sessions. The VA
               treatment thematic interrelationships with control as a catalyst for this positive
               development are shown in Figure 4 and presently individually
               discussed.</p>

                  Low frequencies and music listening</title>
               <p>The first interconnected elements were the low frequency sound vibrations and the
                  music listening. Relaxation was pivotal for eliciting change, which for Jane was
                  at first only possible with the additional music listening element. This is
                  evidenced by the negative response to VA treatment in Session 2 (VA-Silence). The
                  ability to relax was a crucial aspect for her in reducing stress and anxiety and
                  building up the therapeutic space. This was also visible in the VAS-A scores, as
                  anxiety improvement (and worsening) mirrored that of the VAS-R scores. Relaxation
                  was something that Jane reported had previously been quite impossible, however
                  within the context of VA sessions she learned how to do so. The low frequencies
                  allowed her to experience positive bodily sensations, rather than always expecting
                  and experiencing pain. The music listening gave her a means to relax and distract
                  herself from her own thoughts without feeling the stress and frustration of trying
                  and failing to do so in silence. Music was thus a key element in the sessions and
                  process overall, first to help her relax, then as a way to selectively listen and
                  use the music as a distractor as needed within music sessions, and finally to make
                  the choice based on her needs, i.e. choosing to not listen to music.</p>
               <p>This is supported by the quantitative outcomes; Jane was unable to relax without
                  music in Session 2 and her relaxation decreased by 40% (VAS-R), her anxiety
                  increased by 39% (VAS-A), her pain got worse by 22% (VAS-P), and her mood also
                  deteriorated by 18% (VAS-M), all clinically relevant changes. It can also be seen
                  that the worsening in pain during VA-Silence sessions represented clinically
                  relevant change, compared to only minimal and non-clinically relevant worsening in
                  VA-Music sessions. Elicitation of a relaxation response seems to have an important
                  role to play in VA sessions, but interestingly an increase in pain levels
                  apparently did not affect her ability to relax nor reduce her anxiety, suggesting
                  that her overall state of suffering was more related to her anxiety than was
                  affected by her pain. Indeed, severe anxiety seems to have taken precedence over
                  her physical symptoms.</p>

               <title>Support from the practitioner</title>
               <p>Secondly, the interaction with and supportive role of the practitioner was
                  important, especially at a time when she felt isolated in her suffering. The VA
                  sessions were a place where Jane could express herself when seemingly no one else
                  was listening. The hope and expectations that Jane had for the sessions, coupled
                  with experiences of self-efficacy from successful relaxation experiences within
                  the session, founded on the supportive role of the practitioner, are indicative of
                  some elements necessary to elicit therapeutic change.</p>

               <title>Choice</title>
               <p>Thirdly, increasing Jane’s empowerment and self-efficacy was possible through
                  affording her the control and choice of whether to listen to music or not during
                  the sessions. She initially began this choosing process during VA-Music sessions,
                  when she chose to use music as a distraction from her thoughts – weaving in and
                  out of active and passive listening, using music as a way to self-regulate. Music
                  and choice were the factors which opened the process of needs-based and
                  client-centred decision making; although the choice of whether to listen to music
                  was a struggle, she chose based on her needs and wants in that moment. In Session
                  6 when Jane made the pertinent decision to listen to music although it was
                  intended to be a VA-Silence session, it was clear from the quantitative outcomes
                  that she was making this decision from a state of acute anxiety; she experienced
                  the greatest anxiety relief (184%, substantial improvement) in this session,
                  suggesting that the combination of control from her choice, music listening with
                  the low frequency stimulus, and the encouragement from the practitioner were all
                  part of the effect.</p>

            <title>Descriptive triangulation through a member check interview</title>
            <p>In the member check interview, Jane confirmed that she felt less pain and anxiety,
               was in a better mood, and was more relaxed after the VA-Music sessions, and that VA
               treatment was a “good model” for managing her pain and anxiety. She also felt that,
               although there was a lot of variation and disruption in her quality of sleep, the
               relaxation and “maybe a little more of a tired feeling” after VA-music meant she did
               not ruminate as much before bed, attributing this to her better sleep.</p>
            <p>She confirmed that although her pain was not severe during the process, it was
               persistent and interconnected with her anxiety and mood and that her MD had confirmed
               there was no detectable cause for her symptoms. Her experience of music or no music
               was contradictory, “sometimes it was good, sometimes not.” This, she explained, was
               dependent on her level of coping at the time. Jane noticed she was hypersensitive to
               sensory stimuli. If feeling low or stressed, she could tolerate only soft/quiet
               music. When she did listen to music, however, she found that it was difficult for her
               to focus on herself; during the VA-music sessions became immersed in the experience
               and felt like “being on top of waves, and the waves just carried me” but found this
               was a way she could also avoid working on her issues. She also told she was able to
               gain different perspectives on her issues through the discussions with the
               practitioner, experiencing a clarity of mind – “basically somehow lighter.”</p>
            <p>She confirmed that her experience of the treatment was both a physical and mental
               one: “when the chair was vibrating, I could feel it in my body, but when I was quiet
               and concentrated on just that, again it affected my mind.” She told that during the
               process she learned to concentrate on herself and learned that the anxiety would not
               overwhelm her; if she could become quiet, she was then able to enjoy “a sort
               of…peaceful moment.” Initially, the non-music sessions were difficult for Jane
               because she had to “tolerate myself.” She was constantly aware of things happening in
               her surroundings, which was burdensome. She also commented if she noticed a new pain,
               she immediately categorised it as the worst possible pain – “I’m very sensitive to
               that.”</p>
            <p>Jane acknowledged the themes from the qualitative analysis were representative of her
               experience and agreed that control is a major part of her personality. She also
               explained that her pain and anxiety were very tightly intertwined and that they
               usually co-existed. She confirmed that she felt trapped by her anxiety, that she
               struggled to remain in control of all aspects of her life, and that she began to
               change the way she thought about and approached situations because of the VA
               treatments: “I noticed that I have pain even if I did nothing and I learned to just
               live with it a bit better and then it was easier.” She felt that it was “always a
               kind of holiday feeling or something quite exciting [going to the sessions] … I could
               cope somehow better… my head was a bit emptier,” but initially the sessions were
               frightening for her because she did not feel in control of the situation. When not in
               control, “I’m terribly anxious” and she found schedule changes very difficult: “If
               something surprising happens, I feel that the whole meeting is gone to pieces.”</p>
            <p>Jane agreed with the finding of her changing self-reflection during this process. She
               began to teach herself how to approach things differently: “maybe that kind of more
               relaxed view, way of being.” Through attending the sessions, she felt that “my head
               got a bit of a break;” this clarity of mind was a contrast to the “lump” on her chest
               that she described as her anxiety. Finally, she told she was encouraged by the fact
               that the findings from the analysis were relevant to her and that it was “really nice
               for me that they are really my things and I felt I also got something from these
               results [discussed in the member check interview]”.</p>

         <title>Discussion</title>
         <p>This single case study explored the influence of music listening within VA treatment and
            the triad of its components: low frequency sounds, music listening, and therapeutic
            interaction. The quantitative results showed that Jane left the VA sessions feeling much
            more relaxed, which was also corroborated by the qualitative findings and the member
            check interview, and that there were more consistent positive effects in the VA-Music
            condition. This, in addition to improvements in the remaining variables, may point
            towards lower levels of stress, as was reported by Rüütel (<xref ref-type="bibr"
               rid="R2002">2002</xref>). Relaxation is one of the most commonly reported effects
            of VA treatment (<xref ref-type="bibr" rid="CHAR2017">Campbell, Hynynen, &amp; &amp;
               Ala-Ruona, 2017</xref>; <xref ref-type="bibr" rid="PAR2012">Punkanen &amp; Ala-Ruona,
               2012</xref>) and eliciting the relaxation response is beneficial for relieving stress
               (<xref ref-type="bibr" rid="EFS2003">Esch, Fricchione, &amp; Stefano, 2003</xref>).
            The relaxation response (<xref ref-type="bibr" rid="B1975">Benson, 1975</xref>) results
            in reduced stress response and sympathetic nervous system arousal and may explain the
            effects of VA treatment (<xref ref-type="bibr" rid="PAR2012">Punkanen &amp; Ala-Ruona,
               2012</xref>), perhaps due to the repetitive, pulsed nature of the frequency cycles in
            the treatment programmes and the sympathetic resonance between the body and the applied
            frequencies, as well as the transporting effect of listening to one’s preferred
            music.</p>

            <title>Suffering and sensitisation</title>
            <p>The findings showed that Jane was struggling to cope with her unpredictable symptoms
               as well as uncertainty within her family structure, which contributed to an overall
               sense of suffering. Suffering is characterised as a state of distress instigated by
               threat and loss of wholeness, an individualised and subjective experience that
               includes assigning negative meaning to an event or perceived threat (<xref ref-type="bibr"
                  rid="D2011">Cassell, 1998; in Deal, 2011</xref>). After the surgery in 2012 she reported as
               unexpected, Jane was constantly afraid of various pains or sensations she felt,
               fearing they would result in more medical procedures. She was under continuing
               psychological threat to her subjective wellbeing. Medically unexplained symptoms
                  (<xref ref-type="bibr" rid="EU2004">Eriksen &amp; Ursin, 2004</xref>) are highly
               representative of Jane’s suffering. The lack of identifiable cause also may have
               added to hyperawareness of her symptoms. Although the lack of discernible disease
               source for her physical pain was confirmed by a scan during the process, she was
               suffering from the psychological stress and anxiety associated with her fear of new
               pain and what implications it may have. Attentional (hypervigilance) biases in
               interpretation are strongly related to anxiety (<xref ref-type="bibr" rid="VDDPEBVVB2005"
                  >van Diest et al., 2005</xref>). The theory of cognitive sensitisation for
               medically unexplained complaints (<xref ref-type="bibr" rid="B2002">Brosschot,
                  2002</xref>) outlines that those who have an extreme concern about somatic disease
               will develop a cognitive bias for information related thereto. This bias appears in
               an activated cognitive network, meaning that signals related to, for example, pain
               are more closely observed and noticed by us. As a result, one would over-report,
               misattribute, or over-interpret these somatic sensations based on their own fears or
               illness beliefs. Jane was highly sensitised to all sensations – both somatic and
               psychological – and had developed a continued level of anxious suffering because of
               this cognitive sensitisation to her medically unexplained symptoms. As she explained
               in the member check interview, she was trying to re-train this response.</p>
            <p>Four themes related to suffering are noted by Reed (<xref ref-type="bibr"
                  rid="D2011">2003, in Deal,
                  2011</xref>): isolation, hopelessness, vulnerability, and loss. Essential to
               alleviating suffering is a sense of hope, with a focus on a realistic future. Our
               perceived reality becomes clouded when one loses hope, as it results in a lack of
               desire to survive the experience (<xref ref-type="bibr" rid="RCJ2014">Rolley, Chang,
                  &amp; Johnson, 2014</xref>). Jane’s experiences can be categorised under these
               themes of suffering such that she was alone in her suffering and initially felt
               hopeless and helpless, struggling for control, leading her to a feeling of
               vulnerability. She greatly disliked being out of control in all situations and since
               her sudden health issues, she had lost the life she had once led and was lost in her
               own sphere of anxiety, trapped in her own thoughts.</p>
            <p>Yet, Hart (<xref ref-type="bibr" rid="H2018">2018</xref>) discussed two types of
               suffering: one in which one feels worried, hopeless, miserable, angry, and worthless
               with the “stressful anxiety of loss and responsibility” (p. 142), and the other in
               which one glimpses hope, learning to see things optimistically and gratefully. The
               act and experience of suffering is not only a solitary state but also one in which
               one learns to see the way forward; it is both dissonance and consonance. Music
               listening - and the choice to listen or not – was a marker of both of these types of
               suffering for Jane. First, having sessions without music listening were impossible in
               this worried, hopeless, and miserable state, but later, in choosing to <italic>not
               </italic>listen to music in Session 8 - thereby listening to her own needs - she was
               able to see things optimistically, leaving the sessions with a “free feeling” and
               getting over her fear of silence (“I think I beat my fear”). Music is widely used to
               increase one’s sense of wellbeing and act as a distractor from thoughts and feelings,
               improve mood and reduce anxiety, and decrease pain (<xref ref-type="bibr"
                  rid="KD2005">Kemper &amp; Danhauer, 2005</xref>; <xref ref-type="bibr" rid="N2008"
                  >Nilsson, 2008</xref>), which was certainly the case for Jane. Hanser (<xref
                  ref-type="bibr" rid="H2014">2014</xref>) describes the role of music in framing
               the experience of pain as “an ever-changing phenomenon that rises and falls as the
               music changes in synchrony. As these dimensions shift, the perceptual path of pain
               ebbs and flows, and it is possible for pain to dissipate in the mind of the listener”
               (para. 15). This was also the case for Jane and her anxiety; as the music played, the
               perceptual path of her anxiety ebbed and flowed so that it dissipated and she was
               able to relax, reducing her bodily tension and pain.</p>

            <title>Listening</title>
            <p>Due to Jane’s isolated suffering, she lamented having no one with whom to talk and thus
               resorted to suppressing her emotions, spurring more anxiety. One’s attempts to
               understand and endure one’s suffering are eased by the sharing of this experience
               with others, so a listener is an important aspect of any therapeutic process (<xref
                  ref-type="bibr" rid="D2011">Deal, 2011</xref>). Listening to and conveying that
               the client has been heard and understood are important elements in building up a
               supportive environment (<xref ref-type="bibr" rid="PFOFAMF2012">Pinto et al.,
                  2012</xref>). In the case of VA treatment, the practitioner takes on a supportive
               role for the client’s self-exploration in a client-centred approach by providing the
               client the opportunity to make choices supporting their own healthcare. Patient
               empowerment and self-efficacy are essential for eliciting change and clients taking
               control of their own lives and wellbeing; further, there has been increased emphasis
               on the identification of patients’ healthcare wishes and an increase in patient
               autonomy (<xref ref-type="bibr" rid="LP2006">Laugharne &amp; Priebe, 2006</xref>).
               One way in which practitioners can support patient empowerment is to assume a guiding
               or coaching role (<xref ref-type="bibr" rid="C1997">Chamberlin, 1997</xref>). In
               Jane’s case, this involved affording her the possibility to make the choice to listen
               to music through listening to her own needs. Jane listened to and expressed her own
               needs, which the practitioner heard and acknowledged. Choice has been shown to have
               positive consequences in educational, workplace, and health contexts (<xref
                  ref-type="bibr" rid="PCR2008">Patall, Cooper, &amp; Robinson, 2008</xref>),
               leading to a sense of personal control (<xref ref-type="bibr" rid="PCR2008">Taylor,
                  1989, cited in ibid.</xref>).
               When a choice has important implications (i.e. eliciting relaxation for anxiety
               reduction), it may be more difficult to make (e.g. choosing whether to listen to
               music or not), particularly when the options are equally attractive; individuals
               experience increased motivation, perseverance, performance, and production when they
               assert their autonomy through choice-making (<xref ref-type="bibr" rid="PCR2008"
                  >Patall, Cooper, &amp; Robinson, 2008</xref>). Choice has also been suggested to
               influence patients’ commitment and motivation for attending therapy (<xref
                  ref-type="bibr" rid="RTJ1999">Rokke, Tomhave, &amp; Jocic, 1999</xref>). In the
               case of providing choice of music to which patients could listen for managing pain,
               their preference was important as there was ultimately no difference in the pain
               outcomes between patients choosing Taiwanese or American music (<xref ref-type="bibr"
                  rid="HGZ2010">Huang, Good, &amp; Zauszniewski, 2010</xref>). The authors wrote
               that preference is integral when one employs music listening on a long-term basis for
               pain management. Jane’s choice was a pivotal moment in her treatment process, as it
               opened the door towards exploring the meaning and use that she could herself
               attribute to the music listening.</p>

            <title>Implications for practitioners</title>
            <p>The results and findings from this study suggest VA treatment in general may be
               beneficial for improving pain, mood, anxiety, and relaxation for a client with
               medically unexplained symptoms. As such, when comparing the influence of music within
               the treatment protocol, an important finding of this research is that the client’s
               preference for listening to music should supersede the theoretical understanding of
               the physiological and psychological effects music has on us (discussed in the section
                  <italic>Music interventions for relieving pain and
                  mood</italic>).<italic> </italic>The practitioner’s role within the treatment
               sessions to support a client’s therapeutic process and safely deliver VA treatment
               also means the practitioner should help the client to make an informed decision on
               whether music listening could be used; this would be based on the needs and goals of
               the overall process as well as a single treatment session. Therefore, this study
               supports the use of goal-directed music listening rather than delivering music
               listening solely based on research evidence.</p>

            <title>Limitations of the research</title>
            <p>The study design employed here, the single case experimental design, was chosen to
               evaluate how one client receiving VA treatment sessions would respond to both the
               presence and absence of the music listening element. Therefore, carryover to other
               patients – even those with a similar configuration of symptoms – is problematic
                  (<xref ref-type="bibr" rid="CGK2012">Charness, Gneezy, &amp; Kuhn, 2012</xref>).
               In general, the disadvantages of exposing one participant to multiple treatments
               relate to the confounding elements inherent in an individual’s experience, especially
               in a more naturalistic setting (ibid.). As such, the results presented here are to be
               interpreted with caution, as the treatment process over time – regardless of the
               specific condition of each session per se – influenced the overall effects of the
               music listening element. AB designs as such can be useful in exploring the
               feasibility of an intervention, but do not provide definitive indications of the
               effectiveness of a treatment (<xref ref-type="bibr" rid="MGPE2014">Manolov, Gast,
                  Perdices, &amp; Evans, 2014</xref>). On the other hand, the varied treatment
               responses also highlight the difficulty in managing medically unexplained symptoms
               and the many external factors influencing a therapeutic process.</p>
            <p>Another potential limitation of this study is the fact that EAC filled two
               roles, one as the VA treatment practitioner and the other as a researcher. She collected all data in the role of practitioner and also conducted all data analysis
               and interpretation; despite the qualitative and quantitative data being analysed
               separately in their entirety before the integrated analysis, this process could not
               be completely separate as a result of this role overlap. This nevertheless may also
               be seen as advantageous, as EAC had a complete picture of the process from a
               practitioner’s perspective from the sessions to the member check interview as a
               result of the dual roles (as discussed in section <italic>Roles of the researchers /
                  practitioner</italic>).</p>
            <p>Finally, Visual Analogue Scales may have been too simplistic a measurement tool to
               assess Jane’s nuanced experiences. The verbal processing / qualitative data were
               therefore extremely important in supporting the quantitative results. The broader
               topics of discussion between the client and practitioner during the sessions allowed
               for a more complex examination of Jane’s contextual therapeutic experiences, but the
               integration of diverse data sources – the quantitative as specific and qualitative as
               more general explorations – was more complicated as a result. Although it may have
               potentially been beneficial to conduct more formalised interviews of her experiences
               pertaining directly to the variables under examination, this would have compromised
               the integrity of the therapeutic context. The research process and outcomes of this
               study therefore support the use of mixed methods as a means of exploring how a client
               may respond to a therapeutic intervention when having diverse symptoms of no
               discernible medical source, despite the potential pitfalls of single case research in
               general.</p>

            <title>Areas for further exploration</title>
            <p>The client’s specific connection to their preferred music may be important in
               sensation perception. Having a clearer idea of how an individual responds to certain
               music would be an important step in further understanding the interaction of the VA
               treatment elements. This supports the necessity of the therapeutic and supportive
               role of the practitioner in planning and executing the therapy process, with the
               client sharing the responsibility in how their treatment progresses. Understanding
               more closely the individual benefits and cumulative effects of each arm of the VA
               treatment triad works towards more effective and safe utilisation of VA. More
               research is also needed to explore how the VA treatment elements work together for
               various target groups such as patients with complex and interacting symptoms.</p>

         <title>Conclusion</title>
         <p>Music listening with low frequency sound vibration and therapeutic interaction was
            beneficial for reducing anxiety, improving mood, and reducing pain with potential
            implications for improving quality of sleep for a client with medically unexplained
            symptoms. Low frequency sinusoidal sound vibration and therapeutic interaction with and
            without music listening was beneficial for relaxation. Music ultimately became an
            opportunity for Jane to learn how to both actively and passively self-regulate her
            anxiety, and the choice of not listening to music was equally important as it enabled her
            to address and engage with her own needs. Choosing to listen to music or not was
            supported and reinforced by the practitioner, as the choice was based on Jane’s current
            needs and served to empower Jane, important for therapeutic change. Although more
            research is needed, music in this case was an important pivotal point of change in the
            therapeutic process, enabling the participant to make positive choices for her own
            wellbeing. The choice of whether to listen to music or not, or indeed the music to which
            one listens, within VA treatment can play an important role in the effect music
            listening may have within a process.</p>
