Yoga for PTSD
Summary
Pioneering research led by Bessel van der Kolk and colleagues has provided preliminary evidence for yoga as an adjunctive intervention for post-traumatic stress disorder. Studies suggest that trauma-sensitive yoga may reduce PTSD symptoms, particularly in populations with treatment-resistant presentations. The body-based nature of yoga is hypothesized to address dissociative symptoms central to PTSD.
Key findings
Van der Kolk’s landmark RCT (2014, n=64 women with chronic treatment-resistant PTSD) reported that 52% of yoga participants no longer met PTSD diagnostic criteria after the intervention, versus 21% of controls. Improvements were most pronounced in affect regulation, interoceptive awareness, and reduced hyperarousal. Physiological studies report changes in autonomic markers such as heart rate variability. Trauma-sensitive yoga protocols emphasize choice and body autonomy.
Methodology
Randomized controlled trials compare yoga to supportive women’s health education. The Trauma Center Trauma-Sensitive Yoga (TCTSY) protocol is the most validated intervention. Outcomes include CAPS-5 interviews, physiological measures (heart rate variability, skin conductance), and self-report instruments. Sample sizes typically range from 30-60 participants per arm.
Criticism / Limitations
Generalizability is limited by samples predominantly consisting of women survivors of interpersonal violence. Long-term follow-up data remains sparse. The comparative effectiveness against evidence-based PTSD treatments like EMDR and CPT has not been directly studied.
Verification notes
Findings come largely from small trials with limited independent replication; yoga is offered in some VA/DoD settings as a complementary therapy, but clinical guidelines call for stronger evidence. Research is consistent with somatic frameworks in trauma treatment.
