Body-and movement-oriented interventions for posttraumatic stress disorder: An updated systematic review and meta-analysis

This study is an update of the meta-analysis we published in 2019 on the effectiveness of body- and movement-oriented interventions (BMOIs) for adults with posttraumatic stress disorder (PTSD) in decreasing PTSD symptoms and secondary outcomes of depressive symptoms, sleep disturbance, and interoceptive awareness. Search terms for BMOIs and PTSD were combined to identify eligible studies in four bibliographical databases. Articles were selected if they included adult participants with a primary diagnosis of PTSD, included BMOI as one of the investigated therapies, were designed as a comparative outcome trial with any control condition, and involved a standardized outcome measure for PTSD symptom severity. This resulted in the addition of 14 new studies compared to the 2019 study. The meta-analysis, which included 29 studies in total, resulted in a mean Hedges' g effect size of 0.50, 95% CI [0.22, 0.79], in decreasing PTSD symptoms, with very high heterogeneity, I2 = 89%. Meta-analyses of secondary outcomes resulted in Hedges' g effect sizes of 0.37, 95% CI [0.08, 0.66] for depressive symptoms; 0.62, 95% CI [0.42, 0.81] for sleep quality; and -0.10, 95% CI [-0.23, 0.43] for interoceptive awareness. The risk of bias analysis resulted in some concerns or high risk of bias in almost all included studies; only one study had a low risk of bias. We conclude that BMOIs may be valuable for patients with PTSD. There is, however, still a lack of high-quality studies with proper control conditions and long-term follow-up periods from which to draw conclusions.
