“…In the current study, music therapists reduced stress by synchronizing breathing with rhythm. This accords with physiological findings showing that heartbeat can be synchronized to the tempo of sedative music (Fukumoto et al, 2010). It also accords with van der Kolk et al’s (2007) assertion that rhythmic activities can reawaken feelings of pleasure and engagement that have been dulled by prolonged trauma exposure.…”

Objective: The importance of integration in psychotherapy is a growing area of research, theory, and practice, especially regarding traumatic events. Although research relates to integration in the context of music therapy with trauma survivors, it has rarely been the main focus of research. The current study investigates which principles and techniques guide music therapists to facilitate integration of trauma survivors. Method: Using the phenomenological approach, analysis of semistructured interviews with 41 experienced music therapists working with traumatized populations was conducted to identify themes regarding their perception on integration. Results: The findings yielded three different ways of integration. Body integration entails the ability of active music playing to serve as a sensorial stimulus that bypasses linguistic and logical mediation and enables clients to live in peace with their body and feel whole. Event integration relates to a process by which a repressed traumatic event reemerges into consciousness through music and leads to emotional and cognitive integration of that event. Lastly, life story integration relates to the ability to perceive a life story as a whole. The process includes embedding a trauma into the natural flow of a life story through music and achieving emotional and cognitive integration. Conclusions: These three ways of integration are conceptualized as a progression of three consecutive levels of integration which may assist music therapists in their work with trauma survivors. Clinical Impact StatementThe findings indicate three consecutive levels of integration which may be achieved in music therapy with trauma clients. Body integration entails the ability of music to be a sensorial stimulus that bypasses linguistic and logical mediation and enables clients to live in peace with their body and feel whole. Event integration is the process by which repressed traumatic events reemerge into consciousness through music and lead to emotional and cognitive integration of the event. Lastly, life story integration is the process of embedding traumas into the natural flow of a life story through music and achieving emotional and cognitive integration.

“…The ability of music to facilitate body integration in trauma survivors is supported by a recent study that shows how active music playing may act as a sensorial stimulus that bypasses linguistic and logical mediation and enables clients to live in peace with their body and feel whole (Bensimon, 2022). This is supported by studies showing that heartbeats can be synchronized to the tempo of sedative music (Fukumoto et al, 2010), and music can influence the breathing rate and induce a relaxation response (Leslie et al, 2019).…”

Objective: Literature on music therapy with incest survivors is scant, and to the best of our knowledge, voicework as a main technique in group settings has not been explored. The current study aimed to examine a voicework intervention with women coping with the effects of incest, understand its meaning for the participants, and examine its potential to promote well-being. Method: Seventeen women coping with complex posttraumatic stress disorder due to incest participated in a voicework group intervention of eight weekly sessions. Therapy included techniques such as breathing, voice improvisation, songwriting, and performance of existing songs. Data were collected via focus groups before and after the intervention and documentation of songs sung during sessions. Data were analyzed according to the interpretative phenomenological analysis approach. Results: Analysis yielded four themes. Personal empowerment relates to participants' enhanced connection with their body and utilization of creativity as an inner resource. Strengthened social ties relates to the group's ability to create a sense of belonging, togetherness, and an infrastructure for improving relationships outside the group. Enhanced belief in God describes renewed willingness to believe in God, and positive perception of the future reflects change from hopelessness toward belief in a better future. Conclusions: Overall, the findings indicate that the intervention enabled the development of personal, social, and spiritual growth and a positive outlook for the future. Findings are interpreted using the domains of the posttraumatic growth theory. Clinical Impact StatementThe findings point at four domains of the posttraumatic growth theory which may be achieved in voicework groups with women coping with incest. Personal empowerment relates to participants' enhanced connection with their body and utilization of creativity as an inner resource. Strengthened social ties relates to the voicework group's ability to create a sense belonging, togetherness, and an infrastructure for improving relationships outside the group. Enhanced belief in God describes renewed willingness to believe in God, and positive perception of the future reflects a change from despair toward belief in a better future.

“…The semantic information of external stimuli, such as the emotional expression (e.g., Cacioppo et al, 1985) and evaluation of one's performance (e.g., Crone et al, 2003Crone et al, , 2004 and physical state (Glass, 2001;Hodossy & Tsakiris, 2020;Lehrer & Gevirtz, 2014;McCraty, 2022;Ring et al, 2015;Shaykevich et al, 2015), have a particularly large influence on ANS activity. Even meaningless external stimuli can alter ANS activity due to changes in the tempo of successive stimuli (Bernardi et al, 2006;Fukumoto et al, 2010;Tanaka et al, 2021;K. Watanabe et al, 2017), attention or anticipation of the next input stimulus (Guerra et al, 2016;Ilves & Surakka, 2012;Lacey & Lacey, 1978, 1980Poli et al, 2007;Simons et al, 1998), and orienting responses that identify the direction of input of external environmental stimuli (Sokolov, 1963).…”

Autonomic nervous system (ANS) is a mechanism that regulates our internal environment. In recent years, the interest in how tactile stimuli presented directly to the body affect ANS function and cortical processing in humans has been renewed. However, it is not yet clear how subtle tactile stimuli below the level of consciousness affect human heart rate and cortical processing. To examine this, subthreshold electrical stimuli were presented to the left forearm of 43 participants during an image-viewing task, and electrocardiogram (ECG) and electroencephalogram (EEG) data were collected. The changes in the R-wave interval of the ECG immediately after the subthreshold electrical presentation and heartbeat-evoked potential (HEP), the afferent signal processing of cardiac activity, were measured. The results showed that heart rate decelerated immediately after the presentation of subthreshold electrical stimuli. The HEP during stimulus presentation was amplified for participants with greater heart rate acceleration immediately after this deceleration. The magnitude of these effects depended on the type of the subthreshold tactile stimuli. The results suggest that even with subthreshold stimulation, the changes in autonomic activity associated with orienting response and related afferent signal processing differ depending on the clarity of the tactile stimuli.
