Trauma-Informed Yoga

Yoga as the starting point

A Military Health System evidence brief describes yoga as a practice that originated in India and, in its traditional form, encompasses ethical living, spiritual practice, physical activity, breathing exercises and meditation. The same brief notes that hatha yoga, which centers on physical postures and can include meditation and breath control, is the most commonly practiced type in the United States. Trauma-informed and trauma-sensitive yoga are adaptations of this physical practice for people with trauma histories, and the sources reviewed do not present them as a separate tradition.

The sources reviewed do not trace when ordinary yoga classes first adopted trauma-aware teaching, and they give no single founding date for the wider trauma-informed approach in yoga. The earliest dated account found comes from the organization that runs the best-known program, described in the next subsection.

The Trauma Center program

The Center for Trauma and Embodiment, a nonprofit that now runs Trauma Center Trauma Sensitive Yoga (TCTSY), states that the program originated in Massachusetts in 2002 and was developed at the Trauma Center in Brookline by Dave Emerson and Jenn Turner in collaboration with Bessel van der Kolk. Its history lists an NIH grant in 2008, a first peer-reviewed article in 2009, a randomized controlled trial in 2014, a 2017 listing in a federal registry of evidence-based programs, the founding of the Center in 2018 and a 2023 trial against Cognitive Processing Therapy. These dates are the organization's own account and were not checked against independent sources.

The 2014 trial report gives its lead author's affiliation as the Trauma Center at Justice Resource Institute, and its authors include the program's co-developer. Program history and the earliest controlled evidence therefore come from closely connected groups, a point later reviews of the field also have to weigh.

Other programs and adaptations

Other trauma-focused yoga programs are described under similar names. One qualitative study interviewed 40 people with PTSD symptoms who took an 8-week trauma-sensitive Kundalini yoga program, and a 2021 pilot article described adapting a protocolized trauma-informed yoga program for youth in a juvenile justice system. Both are descriptions of programs and participant experience rather than tests of effect.

Trauma-informed and trauma-sensitive

A 2026 review distinguishes the two terms. In its abstract, trauma-informed yoga emphasizes understanding how trauma affects body and mind while building safety, empowerment, choice and trust, and trauma-sensitive yoga emphasizes physical practices that build awareness of and connection to the body, integrated with psychological therapy. The review adds that both aim to create a secure environment, and that the relative effectiveness of the two approaches is poorly understood.

Usage in the literature is not consistent. The 2014 randomized trial calls its intervention trauma-informed yoga in its abstract, while a later analysis of the same trial calls it Trauma Center Trauma-Sensitive Yoga. This page uses trauma-informed yoga for the broader teaching stance, trauma-sensitive yoga or TCTSY for the clinical program, and the abbreviation TSY only where a source does.

Program names and related Machipedia pages

The organization that runs the program writes its name as Trauma Center Trauma Sensitive Yoga and describes it as a yoga-based clinical intervention for complex trauma and chronic, treatment-resistant PTSD. A narrative review of five studies uses the abbreviation TSY for the wider group of programs for women with PTSD. This page is a member of the Yoga Styles family on Machipedia; the Yoga, Yoga Therapy and Restorative Yoga pages cover related material, and Somatic Experiencing and EMDR have their own pages as separate approaches to trauma.

Teaching features described by the programs

The Center for Trauma and Embodiment says TCTSY is based on central components of hatha yoga, modified to build empowerment and a more positive relationship to the body. It states that the method does not use physical hands-on adjustments, that participants decide what to do from their own felt sense, and that the emphasis is on internal experience rather than outward appearance or approval.

The 2023 trial paper lists the core components as interoception, invitational language, choice making, noncoercion and shared authentic experience, and describes facilitators who share power with participants and direct attention to body sensations during yoga forms. The paper does not say whether physical assists were used, so the hands-on statement above rests on the program's own page.

Format and setting in studies

Formats in the studies vary. The 2014 trial used a weekly 1-hour class for 10 weeks, and the 2023 trial used 10 weekly 60-minute group sessions led by two interventionists who were TCTSY-certified facilitators holding at least a 200-hour Yoga Alliance teaching credential. A feasibility study added a 12-week protocol of 30 to 40 minutes at the end of group therapy sessions, an extended study used 20 weeks with assigned and monitored home practice, and a qualitative study described 8 weeks of Kundalini yoga.

Facilitator training offered by the program

The program's Foundations training is 20 hours, open to mental health professionals, yoga teachers and other health workers, and the page states that it does not qualify participants to facilitate. Qualifying to facilitate requires the 300-hour Certification Program, a fully online course of about 28 weeks with live weekly meetings and about 12 hours of weekly work. The page states that the course is approved as a 300-hour registered yoga school by Yoga Alliance, that certified facilitators must follow the program's Ways of Being code of conduct, and that more than 850 facilitators are certified.

Uses described by the program

The program describes TCTSY as a yoga-based clinical intervention for complex trauma and chronic, treatment-resistant PTSD. It holds that trauma is linked with a lack of choice and agency, and that focusing on felt sense, with participants in charge of their own movement, restores mind-body connection and a more positive relationship to the body. These are the organization's own statements of purpose.

Rationales given in research reports

The 2014 trial authors state that they explored yoga to increase affect tolerance and to decrease PTSD symptoms, and suggest that yoga may help traumatized people tolerate physical and sensory experiences associated with fear and helplessness. The 2023 trial begins from the observation that first-line trauma-focused therapy in the Department of Veterans Affairs is limited by low treatment initiation, high dropout and treatment refraction, and tests TCTSY as a comparison. A feasibility study tested a yoga segment as an adjunct to group therapy for women who experienced partner violence.

Participant-reported changes

In interviews with 40 people who took an 8-week trauma-sensitive Kundalini yoga program, participants described changes in health and well-being, lifestyle, psychosocial integration and perceptions of self in relation to the world. These are self-reports from a qualitative study without a comparison group and are not evidence that the program caused the changes.

Randomized trials of Trauma Center Trauma-Sensitive Yoga

In the 2014 trial, 64 women with chronic, treatment-resistant PTSD were randomized to trauma-informed yoga or supportive women's health education, weekly for 10 weeks. Of 60 analyzed, 16 of 31 in the yoga group (52%) no longer met PTSD criteria at the end, versus 6 of 29 (21%) in the control group. Both groups improved on the clinician-rated scale (d = 1.07 yoga, d = 0.66 control). A secondary analysis reported small moderator effects, with the program most efficacious for women with fewer adult-onset interpersonal traumas, and called the 2014 trial the only randomized trial of trauma-sensitive yoga at that time.

The 2023 trial randomized women veterans with PTSD related to military sexual trauma at two Veterans Affairs sites to TCTSY (72 women) or cognitive processing therapy (59 women) (intent-to-treat n = 131). Treatment was completed by 47 women (65.3%) in the TCTSY group and 27 (45.8%) in the therapy group. Both groups improved on the clinician-rated scale at 3 months (TCTSY mean 36.73 to 24.03; therapy 35.52 to 22.15); group differences were not significant and equivalence held within plus or minus 10 points. The authors note unblinded assessors, follow-up ending at 3 months and possible use of other therapies; there was no inactive control group.

Smaller and uncontrolled studies

A non-randomized 20-week study in nine women with chronic treatment-resistant PTSD reported reductions in PTSD and dissociation symptoms, and a feasibility study of 17 women found yoga added to group therapy acceptable, with 30% loss to follow-up. Neither design can show that yoga caused the changes.

Systematic reviews

A 2018 review of seven randomized trials of yoga (284 participants) found low-quality evidence for clinically relevant effects on PTSD symptoms compared with no treatment (standardized mean difference -1.10, 95% CI -1.72 to -0.47) and very low-quality evidence for comparable effects with attention control (-0.31, 95% CI -0.84 to 0.22), supporting only a weak recommendation for yoga as an adjunct. A 2024 review of 20 trials reported a pooled self-report effect of -0.51 but no improvement in clinician-reported symptoms, with high bias in individual trials. A review of trauma-sensitive yoga in women found marginal to no effects, and a 2026 symptom-cluster analysis of nine trials found small reductions in intrusions (d = -0.31) and total symptoms (d = -0.29) with substantial risk of bias.

Gaps and guideline status

A 2016 narrative review judged evidence for trauma-sensitive yoga in women with PTSD tentative, and a 2026 review of registered trials found efficacy difficult to validate and dependent on trauma history, age, gender, duration and mode of practice. A Military Health System brief states that the 2017 VA/DoD guideline found insufficient evidence to recommend any complementary and integrative health practice, including yoga, and that yoga is not recommended as a front-line PTSD treatment there. The trials described enrolled adult women, and no controlled trials of trauma-informed teaching in ordinary classes were found.

Relationship to trauma-focused treatment

The 2023 trial describes trauma-focused therapy as first-line treatment for PTSD in the Veterans Affairs system, and the Military Health System brief does not recommend yoga as a front-line treatment. The 2018 review supports only a weak recommendation for yoga as an adjunct. On this evidence, the yoga is a complement to, not a substitute for, trauma-focused psychotherapy. The National Institute of Mental Health directs people with persistent symptoms that interfere with daily life to seek professional help.

Reported harms and distress

The 2023 trial reported no clinically significant adverse events, the 2018 review reported no serious adverse events, and a 2024 review found that six trials reported on serious adverse events and none occurred. In the feasibility study, no one reported emotional or physical harm. These trials were small and short, with attrition, and the sources reviewed do not report how often distress, flashbacks or dissociation arise in classes, so absent reported harm is not absent risk.

For yoga in general, a review of 76 published case reports found that musculoskeletal problems accounted for 27 events (35.5%) and nervous system problems for 14 (18.4%), and advised practice under a qualified instructor. Increasing distress, dissociation or worsening trauma symptoms during or after practice would be raised with the facilitator and a clinician.

Crisis resources and facilitator training

In the United States, the 988 Suicide & Crisis Lifeline can be reached by calling or texting 988 or by chat, and its Get Help page states that it is free and confidential; the National Institute of Mental Health lists 911 for life-threatening situations. Elsewhere, local emergency services and national helplines apply.

The sources reviewed identified no shared credential standard for trauma-informed teaching of ordinary classes. The TCTSY program publishes its own certification pathway and code of conduct, and states that Foundations training does not qualify people to facilitate.
