The conceptual framework for the therapeutic approach used in phase 3 trials of MDMA-assisted therapy for PTSD

Results from multiple recent studies support further evaluation of 3,4-methylenedioxymethamphetamine (MDMA) in conjunction with psychotherapy (i.e., MDMA-Assisted Therapy) in the treatment of post-traumatic stress disorder (PTSD). In two Phase 3 trials, MDMA-Assisted Therapy comprised a short-term, intensive psychotherapy that included three sessions directly facilitated by MDMA (referred to as “experimental sessions”), as well as a number of non-drug psychotherapy sessions. This treatment model aimed to harness the potential of MDMA to facilitate recall and processing of traumatic memories, and to increase learning in a social context, integrating “top-down” and “bottom-up” approaches to trauma-focused care. To date, the conceptual framework for this treatment has not been described in the scientific literature. This omission has contributed to misunderstandings about both the theoretical underpinnings of this modality and the therapeutic approach that emerges from it. This paper delineates the psychotherapeutic concepts, theories, and historical antecedents underlying the inner-directed approach to MDMA-Assisted Therapy for PTSD. Broadly speaking, this therapeutic framework centered the concept of the participant’s inner healing intelligence as the primary agent of change, with the therapeutic relationship being the core facilitative condition fostering the participant’s self-directed movement toward recovery and growth. Corollaries to this holistic, self-directed, relational, and trauma-informed framework include a non-pathologizing approach to the participant’s embodied experience (including the possibility of intense emotional and somatic expression, experiences of multiplicity, suicidal ideation, and multigenerational and transpersonal experiences), as well as the therapists’ own psychodynamic, somatic, and transpersonal awareness, empathic attunement, relational skillfulness, and cultural humility. The use of MDMA in conjunction with this psychotherapy platform outperformed the use of placebo with psychotherapy in Phase 2 and 3 trials, as measured by symptom reduction in participants with PTSD. However, within-group comparisons also identified significant symptom reduction in participants who did not receive MDMA, lending empirical support to the psychotherapy model itself. In addition to comparative efficacy trials, future research should investigate which elements of the conceptual framework and therapeutic approach underlie the clinical benefit in individuals with PTSD.

Transcranial electrical stimulation in post-traumatic stress disorder and brain injury: possibilities of tuning neuronal networks

Transcranial direct current stimulation (tDCS) in the treatment of post-traumatic stress disorder (PTSD) is used to strengthen the inhibitory control of amygdala activity. However, there are still limited meta-analytic studies examining different tDCS protocols on core PTSD symptoms and the relationship between stimulation parameters and effect size. The objective is to investigate the effectiveness of such an intervention, which is a complex combination of a psychotherapy program with tDCS in the treatment of patients with PTSD and mild traumatic brain injury (mTBI) by assessing their level of functioning. 329 veterans (PTSD (n=109), mTBI (n=112), PTSD + mTBI (n=108) were examined using WHODAS 2.0. Standardized treatment was provided as well as psy­chotherapeutic intervention - a combination of psychoeducation with motivational interviewing and acceptance and commitment therapy for PTSD and tDCS. Clinical targets of therapy in the PTSD group were symptoms of intrusion, avoidance, hyperactivation and protocol of tDCS was dorsolateral prefrontal cortex arousing stimulation. In PTSD + TBI group clinical targets were neurocognitive symptoms, intrusion symptoms, avoidance, hyperactivation and tDCT protocol was motor cortex-supraorbital area inhibitory stimulation. The targest for TBI group was neurocognitive symptoms and tDCS protocol was occipital region exciting stimulation. The long-term effectiveness and the impact on neuroplasticity processes allow considering transcranial direct current stimulation as a promising method of neurorehabilitation of patients with a combination of posttraumatic stress disorder and mild traumatic brain injury.

Effectiveness of written exposure therapy for Korean patients with post-traumatic stress disorder: non-randomized treatment-as-usual waitlist-controlled study

ABSTRACT Written exposure therapy (WET) is a five-session exposure-based protocol for treating post-traumatic stress disorder (PTSD). The brevity and tolerability of WET present the potential to overcome barriers in implementing evidence-based therapy for PTSD within the Korean mental healthcare system. This study investigated the effectiveness of WET in Korean patients with PTSD through a waitlist-controlled trial (KCT0008112). A total of 57 patients with PTSD were allocated non-randomly to either WET (n = 27) or treatment-as-usual waitlist groups (n = 30). Both groups were followed up until the twenty-fourth week after the initial session. Primary outcomes assessed included PTSD symptoms, depressive symptoms, and general function. In the WET group, significant improvements were observed in PTSD symptoms, depressive symptoms, and general function compared to the control group. After the waiting period, the waitlist group also participated in WET, and exhibited significant improvement in all scores. The between- and within-group effect sizes were large. The dropout rate in both groups was 10.9%, and the mean satisfaction ratings were 28.24 ± 3.33 (range 22–32; scale range 8–32). The present study provides evidence of WET successfully reducing PTSD and depressive symptoms and improving general function among Korean patients with PTSD. Moreover, WET was well tolerated and received by Korean patients with PTSD.

Like a Punch in the Gut: A Novel Perspective On Annual Recurrences of Ulcerative Colitis.

Ulcerative colitis (UC), a chronic inflammatory bowel disease, causes stomach pain, diarrhea, and rectal bleeding. The exact cause is unknown, but it is thought to involve genetic, environmental, and psychological factors. Some people experience annual flare-ups without obvious reason. This article adopts a theory-driven approach to consider how and why past traumatic events may contribute to annual flare-ups. We applied learning theory, which explains the development of re-experiencing phenomena in post-traumatic stress disorder (PTSD), to better understand the occurrence of annual flares in patients living with UC. Two possibilities emerged in which associative learning may contribute to annual UC flares. First, flare-ups could be a physical response to sensory cues in the present that overlap with trauma experienced at the first onset of UC. Annual episodes may strengthen the UC flare as a learned physiological response to trauma reminders. Second, flare-ups may result from elevated stress due to trauma re-experiencing at anniversaries. Sensory features of the initial UC trauma may be associated with strong reactions, which generalize to similar stimuli, triggering re-experiencing symptoms and increasing psychological stress. Elevated stress raises glucocorticoid levels, promoting UC-specific inflammation. Stimulus discrimination from cognitive therapy for PTSD may help to over-ride the associations that have formed between sensory features of past trauma, linked reactions, and similar cues in the present. Research is needed to understand how traumatic events influence the onset and recurrence of ulcerative colitis, as well as the potential benefits of stimulus discrimination for reducing the frequency of annual flares.

Examining the impact of brief couples-based posttraumatic stress disorder treatments on anger and psychological aggression in veterans and their partners.

Anger can adversely impact functioning in veterans. Psychological aggression, which is related to but distinct from anger, is particularly detrimental to veterans' mental health. Research examining anger and psychological aggression following individual therapy for posttraumatic stress disorder (PTSD) has demonstrated small effect sizes. Treatments that directly target conflict management and interpersonal functioning, both regarding content and delivery to veterans and their loved ones (e.g., couples-based PTSD treatments), may be more effective in alleviating anger symptoms. This study examined whether larger reductions in anger and psychological aggression would be observed in a couples-based intervention compared to an active comparator at posttreatment and follow-up. Data were derived from a randomized trial comparing brief cognitive-behavioral conjoint therapy for PTSD (bCBCT) and PTSD family education (PFE). Participants were 137 veterans and their intimate partners (bCBCT: n = 92, PFE: n = 45). We observed within-condition significant reductions in angry temperament, d = -0.47, p <.001, and angry reaction, d = -0.26, p =.004, among veterans in bCBCT but not PFE, |d|s = 0.13-0.17, ps =.166-.268. Veterans and partners in both conditions reported reductions in psychological aggression, |d|s = 1.09-1.46, ps <.001. There were no significant differences between the treatment conditions on any outcome, ps =.103-.443, and there were no significant changes in anger between posttreatment and follow-up, |d|s = 0.07-0.24, ps =.052-.582. Couples-based interventions for PTSD, including bCBCT and PFE, can be effective in improving aspects of anger among veterans and their intimate partners.

Psychedelic research at a crossroads

There is an urgent need to develop better treatments for mental health conditions that affect one in every eight people in the world. To combat this concern, psychedelic drugs have been combined with psychotherapy and studied in clinical trials in the United States and Europe. Psychedelics are hallucinogenic drugs that alter brain activity and facilitate altered states of consciousness. The proposed benefits of psychedelic-assisted therapy (PAT) include relatively short treatment times and stronger effects compared to other treatments. Although results of trials using MDMA for trauma or psilocybin for depression are promising, PAT is controversial because many questions about its safety and effectiveness are unanswered. This is evident in the recent ruling by the US Food and Drug Administration against the approval of MDMA therapy for post-traumatic stress disorder and the retraction of several papers about MDMA trials owing to unethical conduct by study therapists and data integrity, among other concerns. This field is at a crossroads, and the research community must address several obstacles to transition from exploratory trials to established, evidence-based treatments while avoiding pitfalls that can hinder advancement.

Integration of a smartphone app with posttraumatic stress disorder treatment for frontline workers: a pilot study

ABSTRACT Objective Treatment of posttraumatic stress disorder (PTSD) is hindered by limited uptake, early drop-out and non-response. This pilot study aimed to explore the feasibility, acceptability, and usability of a mobile app as part of a blended approach to treating frontline workers experiencing PTSD. Method A single-group pre-post study was conducted with 10 adult frontline workers (firefighters, police, correctional workers) receiving trauma-focused cognitive-behavioural therapy for PTSD. Participants used an app (Support Base) designed to consolidate session content and encourage independent skills practice. At post-treatment, feasibility was assessed via app usage data and participant feedback, usability via the mHealth App Usability Questionnaire, and acceptability via items from the Mobile Application Rating Scale: user version. Results Usability ratings were above average and the app received an overall mean rating of 3.4/5. Despite generally positive attitudes towards using technology in therapy, participants had low levels of confidence/experience with wellbeing apps and almost half preferred using the standard treatment workbook. Clinicians highlighted a range of client barriers to app use, including difficulties in clinician/client collaboration. Overall, there was significant pre- to post-treatment improvement in clinical measures of PTSD and depression, but this change cannot be tied to app use. Conclusions Although Support Base was viewed by participants as usable and acceptable, there were feasibility issues which must be further considered in delivering this form of care. Due to the uncontrolled study design, any additive effects of the app beyond standard clinical treatment could not be assessed. The development of a more integrated blended care model is a potential avenue for future research.

Long-term effects of dialectical behaviour therapy for posttraumatic stress disorder and cognitive processing therapy 9 months after treatment termination

ABSTRACT Background: The complexity of posttraumatic stress disorder (PTSD) symptoms related to childhood abuse (CA) present challenges for effective psychotherapeutic treatment. Consequently, there is great interest in the long-term effectiveness of psychological treatments for this population. Objective: This study aims to investigate the long-term outcomes of Dialectical Behaviour Therapy for PTSD (DBT-PTSD) and Cognitive Processing Therapy (CPT) 9 months after treatment termination. Method: This is a long-term analysis from a randomised-controlled trial of DBT-PTSD versus CPT (registration number DRKS00005578). Initially, 193 individuals with CA-related PTSD were randomly allocated to receive either DBT-PTSD (n = 98) or CPT (n = 95). The primary outcome the Clinician-administered PTSD-Scale for DSM-5 (CAPS-5) was administred at baseline, treatment completion (15 months post-randomization) and at the 9-month follow-up. Secondary outcomes included self-reported PTSD severity (PCL-5), dissociation (DSS), severity of borderline symptoms (BSL-23), and psychosocial functioning (GAF). Results: No significant changes were observed in the primary (CAPS) and all other outcomes from post-intervention to 9-months follow-up in both the DBT-PTSD (CAPS: Mpost = 15.60, M follow-up = 14.93) and CPT group (CAPS: Mpost = 18.80, Mfollow-up = 17.41). Between-group analyses at 9-months follow-up were significantly in favour of DBT-PTSD compared to CPT with small to medium effect sizes on all outcomes ranging from d = 0.35 on the CAPS to d = 0.57 on the BSL-23 and GAF. Conclusions: Our results indicate that treatment effects of psychotherapy addressing complex presentations of PTSD persist 9 months after treatment termination. In addition, the superiority of DBT-PTSD as compared to CPT found at treatment termination, was confirmed at 9-months follow-up.

Effects of One-to-One Trauma Center Trauma-Sensitive Yoga Sessions on Psychological Symptoms and Interoception over 6 Months.

Posttraumatic stress disorder (PTSD) is a serious health condition that adversely affects the mind and body. Current first-line treatment for PTSD tends to focus on the mind and overlook the impacts of trauma on the body. Trauma Center Trauma-Sensitive Yoga (TCTSY) is an evidence-based adjunctive therapy for complex trauma and PTSD that uses a body-based approach to trauma healing. Although designed to be used in group or individual contexts, previous studies have focused only on TCTSY facilitated in groups. The present study examined the effects of one-to-one TCTSY (i.e., one participant receiving TCTSY services, not in a group TCTSY context) on anxiety, depression, posttraumatic stress, interoception, substance use, and sleep over time. Using an observational approach, all certified TCTSY facilitators received the study invitation to share with clients who were enrolled in one-to-one TCTSY services. Ten clients participated in the study across four countries (women n = 8; mean age 44.80 ± 11.91; PTSD diagnosis n = 9). Clients completed Qualtrics surveys at TCTSY sessions in June-December 2022. Linear mixed-model analyses found that anxiety, depression, posttraumatic stress symptoms, attention regulation, self-regulation, and body listening significantly improved over time. There were no significant changes in sleep or substance use from pre- to post-study. TCTSY is a somatic approach for managing trauma symptoms and enhancing interoceptive awareness. Extensions of the present study are warranted to further understand the effects of one-to-one TCTSY for trauma care.

Bolstering family therapy: Assimilating EMDR into ABFT in youth residential treatment.

The psychotherapy field has a long history of integration to improve treatment effectiveness. One type, assimilative integration, offers innovative opportunities to family therapy to incorporate the clinical and research contributions of different approaches. This paper contributes to the literature on integration by exploring how Eye Movement Desensitization and Reprocessing (EMDR) can be assimilated into Attachment-Based Family Therapy (ABFT) for youth in residential psychiatric treatment. ABFT seeks to improve attachment security to parental figures by asking adolescents and young adults to discuss attachment ruptures. This process, specially designed for patients with internalizing disorders, can provoke anxiety, particularly for a patient population that commonly has a history of trauma and adverse life experiences. EMDR is a first-line therapy for post-traumatic stress disorder and has the potential to be effective in treating various other mental health conditions. When patient emotional withdrawal or dysregulation due to breaches in trust between child and parent emerges in ABFT, EMDR may help desensitize associated memories and bolster the family therapy process. The authors provide an overview of both models, and a detailed case study as an example. The paper concludes with a discussion on implications, integration efforts, and limitations.

A Meta-Analysis of Interpersonal and Psychodynamic Psychotherapies for Posttraumatic Stress Disorder.

Established trauma-focused cognitive-behavioral therapies for posttraumatic stress disorder (PTSD) have remission rates of approximately 30%-40%. Alternatively, interpersonal psychotherapy (IPT) and psychodynamic psychotherapy (PDT) focus on disrupted attachment, mentalization, and social connection in PTSD and may help some patients. The authors conducted a meta-analysis on these interpersonal and affect-oriented approaches to treating PTSD. Building on a prior meta-analysis, the authors searched for randomized controlled trials (RCTs) comparing IPT or PDT with other established PTSD treatments or control conditions for adults diagnosed as having PTSD. Random-effects meta-analyses were conducted to assess outcome effect sizes and dropout rates. RCTs were rated via the Randomized Controlled Trial Psychotherapy Quality Rating Scale. Ten RCTs (eight of IPT) comparing IPT or PDT with control (k=7) or active treatment (k=4) conditions were identified, nine of which were of adequate quality. IPT (k=5) and PDT (k=2), when analyzed together, were superior to control conditions overall (g=-1.14, p=0.011 [as was IPT alone: g=-0.88, p=0.034]) and to waitlist (g=-1.49) and treatment-as-usual (g=-0.70) groups. Effect sizes, however, may have been inflated by outliers or publication bias. IPT (k=3) and PDT (k=1), when analyzed together, were equally efficacious compared with other active PTSD treatments (primarily exposure-based psychotherapies), as was IPT alone, and had lower dropout rates (relative risk=0.63, p=0.049 for IPT and PDT analyzed together; relative risk=0.61, p=0.098 for IPT alone). Affect-focused therapies hold promise in the treatment of PTSD. IPT has demonstrated efficacy in multiple trials, whereas the evidence base for PDT is sparse.

"It made me feel more alive": A qualitative analysis of quality of life improvements following completion of trauma-focused therapy for posttraumatic stress disorder.

Posttraumatic stress disorder (PTSD) is associated with poor quality of life. Although randomized clinical trial data show improvements in quality of life following trauma-focused therapies (TFTs), including prolonged exposure therapy (PE) and cognitive processing therapy (CPT), less is known about how these improvements are experienced from the trauma survivor's perspective. A national sample of 60 veterans who recently completed TFT as part of routine care at U.S. Department of Veterans Affairs facilities participated in semistructured qualitative interviews during which the impact of treatment on quality of life was explored. Following a mixed deductive/inductive approach, six interrelated themes describing changes in quality of life emerged: full participation in social activities, greater emotional intimacy in relationships, improvements in parenting, expanded engagement in hobbies and community, increased occupational commitment and confidence, and more joy in life. The data highlight the positive impact of treatment on quality of life and provide depth to quantitative findings demonstrating improvements in quality of life following TFT.

Feasibility, Safety, and Acceptability of Cognitive Processing Therapy for PTSD Following a Recent Suicide Attempt: A Case Study

While cognitive processing therapy (CPT) has been found to be highly effective in the treatment of posttraumatic stress disorder (PTSD) and comorbid suicidal ideation, it is unknown how soon after a suicide attempt this treatment may be safe and effective. This case study investigates the effectiveness of weekly, telehealth-delivered CPT for a client with PTSD following a suicide attempt on the anniversary of a traumatic event. Results indicate a clinically meaningful reduction in PTSD symptoms and loss of PTSD diagnosis, as measured by the PTSD Checklist for DSM-5 (PCL-5), and a lack of further suicidal ideation or attempts. These results were maintained at long-term follow-ups at 1-, 3-, and 12-month periods. Qualitative data from the client further supported the effectiveness and acceptability of treatment. This case study suggests the potential of CPT as a valuable intervention for individuals with PTSD recovering from suicide attempts and highlights the importance of further research in this area. In support of this, the case study also suggests the use of nuanced suicide risk assessments, such as the fluid vulnerability theory (FVT), to respond to fluctuations in suicide risk in high-risk clients.

Psilocybin Facilitates Fear Extinction: Importance of Dose, Context, and Serotonin Receptors.

A variety of classic psychedelics and MDMA have been shown to enhance fear extinction in rodent models. This has translational significance because a standard treatment for post-traumatic stress disorder (PTSD) is prolonged exposure therapy. However, few studies have investigated psilocybin's potential effect on fear learning paradigms. More specifically, the extents to which dose, timing of administration, and serotonin receptors may influence psilocybin's effect on fear extinction are not understood. In this study, we used a delay fear conditioning paradigm to determine the effects of psilocybin on fear extinction, extinction retention, and fear renewal in male and female mice. Psilocybin robustly enhances fear extinction when given acutely prior to testing for all doses tested. Psilocybin also exerts long-term effects to elevate extinction retention and suppress fear renewal in a novel context, although these changes were sensitive to dose. Analysis of sex differences showed that females may respond to a narrower range of doses than males. Administration of psilocybin prior to fear learning or immediately after extinction yielded no change in behavior, indicating that concurrent extinction experience is necessary for the drug's effects. Cotreatment with a 5-HT2A receptor antagonist blocked psilocybin's effects for extinction, extinction retention, and fear renewal, whereas 5-HT1A receptor antagonism attenuated only the effect on fear renewal. Collectively, these results highlight dose, context, and serotonin receptors as crucial factors in psilocybin's ability to facilitate fear extinction. The study provides preclinical evidence to support investigating psilocybin as a pharmacological adjunct for extinction-based therapy for PTSD.

Clinicians’ perspectives on retraumatisation during trauma-focused interventions for post-traumatic stress disorder: A survey of UK mental health professionals

Concerns regarding retraumatisation have been identified as a barrier to delivering trauma-focused therapy for post-traumatic stress disorder (PTSD). We explored clinicians’ understanding of what constitutes potential signs of retraumatisation (PSoR), reported incidences of witnessing retraumatisation, use of (and confidence in) therapies for PTSD, fear of retraumatisation during therapy for PTSD, and whether having witnessed retraumatisation was associated with these variables. We surveyed 348 clinicians. There was variation in what clinicians viewed as PSoR. Retraumatisation was reported by clinicians in 3.4 % of patients undergoing trauma-focused therapy for PTSD. A variety of trauma-focused and non-trauma-focused therapies were routinely used, yet 14.4 % reported not using trauma-focused therapy. There was a significant negative correlation between participants’ highest reported confidence in trauma-focused therapy and endorsement of PSoR (r = −.25) and fear of retraumatisation (r = −.28). Mean fear of retraumatisation was 30.3 (SD=23.4; a score we derived from asking participants out of 100 how much they worry about trauma-focused therapy being harmful in its own right/leading to a worsening of PTSD symptoms). Participants who had witnessed retraumatisation reported significantly greater endorsement of PSoR (d=.69 [95 % CI .37, 1.02]) and fear of retraumatisation (d=.94 [95 % CI .61, 1.26]). Confidence in using therapies for PTSD was varied and related to how clinicians understood retraumatisation. Retraumatisation is uncommon, but there is variability in clinicians’ interpretation of what retraumatisation is, and its utility warrants research.

New recognition of the heart-brain axis and its implication in the pathogenesis and treatment of PTSD.

Post-traumatic stress disorder (PTSD) is a complex psychological disorder provoked by distressing experiences, and it remains without highly effective intervention strategies. The exploration of PTSD's underlying mechanisms is crucial for advancing diagnostic and therapeutic approaches. Current studies primarily explore PTSD through the lens of the central nervous system, investigating concrete molecular alterations in the cerebral area and neural circuit irregularities. However, the body's response to external stressors, particularly the changes in cardiovascular function, is often pronounced, evidenced by notable cardiac dysfunction. Consequently, examining PTSD with a focus on cardiac function is vital for the early prevention and targeted management of the disorder. This review undertakes a comprehensive literature analysis to detail the alterations in brain and heart structures and functions associated with PTSD. It also synthesizes potential mechanisms of heart-brain axis interactions relevant to the development of PTSD. Ultimately, by considering cardiac function, this review proposes novel perspectives for PTSD's prophylaxis and therapy.

Light Therapy in Post-Traumatic Stress Disorder: A Systematic Review of Interventional Studies.

Background: Due to limitations in treatment strategies for post-traumatic stress disorders (PTSD), therapeutic options such as light therapy (LT) have garnered some interest in recent years. We aimed to review the effectiveness of LT in patients with PTSD. Methods: Using PubMed, PsycINFO, Web of Science, the Cochrane database, ClinicalTrials.gov, and PTSDpubs, we systematically searched for papers assessing the effect of LT in PTSD. We evaluated the risk of bias of included studies using the Cochrane handbook, and synthesized our findings following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines (PRISMA 2020). Results: From 140 initial papers, we included four randomized controlled trials (RCTs) and one single-arm study. The study sample size ranged between 15 and 82, the mean age (standard deviation) varied between 31.4 (8.8) and 44.9 (11.8) years, and LT was applied for four or six weeks. The risk of bias was low in three studies, and of some concern in the two other trials. Most studies reported no significant differences between LT and placebo regarding effects on subjective (sleep quality and insomnia severity) and objective sleep parameters. LT was associated with a significant improvement in PTSD symptom severity in the single-arm study and two RCTs, as well as a greater retention of extinction learning. Results on depression and anxiety were discrepant. Conclusions: This review revealed that relevant studies are scarce, with promising findings concerning PTSD symptoms, but inconsistencies for the other parameters. Further research projects are needed to better explore this topic.

Enhancing Agency in Posttraumatic Stress Disorder Therapies Through Sensorimotor Technologies.

Posttraumatic stress disorder (PTSD) is a significant public health concern, with only a third of patients recovering within a year of treatment. While PTSD often disrupts the sense of body ownership and sense of agency (SA), attention to the SA in trauma has been lacking. This perspective paper explores the loss of the SA in PTSD and its relevance in the development of symptoms. Trauma is viewed as a breakdown of the SA, related to a freeze response, with peritraumatic dissociation increasing the risk of PTSD. Drawing from embodied cognition, we propose an enactive perspective of PTSD, suggesting therapies that restore the SA through direct engagement with the body and environment. We discuss the potential of agency-based therapies and innovative technologies such as gesture sonification, which translates body movements into sounds to enhance the SA. Gesture sonification offers a screen-free, noninvasive approach that could complement existing trauma-focused therapies. We emphasize the need for interdisciplinary collaboration and clinical research to further explore these approaches in preventing and treating PTSD.
