abstract
BACKGROUND: Sudarshan Kriya Yoga (SKY), a breath-based yoga intervention, has demonstrated safety and efficacy in posttraumatic stress disorder (PTSD) patients subsequent to natural disaster or war, but has not been explored in civilians with PTSD from a wider range of trauma. We hypothesized that it would be feasible to conduct a clinical trial of SKY in PTSD resulting from a wide range of trauma. METHODS: Outcomes were feasibility measures including rates of enrollment and retention, adherence to study protocol; as well as changes in PTSD symptoms, other mood symptoms, and physiological measures. Male and female participants aged 18-75 years were enrolled in a feasibility trial. They attended a 6-day learning phase of SKY followed by 7 sessions over 11 weeks as an adjunct to their usual treatment. RESULTS: Forty-seven participants were screened and 32 were enrolled over 9 months. Consistent with retention rates of other PTSD trials, 13 withdrew from the study prior to week 12. Twenty-one participants met intervention attendance requirements, completed 95% of planned study assessments and were included in final analyses. Participants experienced clinically significant decrease in PTSD symptoms on the posttraumatic stress disorder checklist (PCL-5) scores at week 12 mean difference, Mdiff (standard deviation [SD]) = -10.68 (14.03), P = 0.004; Cohen's d = 0.58, which was sustained at week 24 Mdiff (SD) = -16.11 (15.20), P < 0.001; Cohen's d = 0.91. CONCLUSIONS: It is possible to conduct a clinical trial of SKY in a routine psychiatry clinic serving patients with PTSD due to a wide range of trauma. Future studies should include an RCT design.
