Fifty-five service members meeting diagnostic criteria for PTSD were randomised to usual PTSD care (UPC) plus eight 60-minute sessions of acupuncture conducted twice weekly, or to UPC alone. Mean improvement in PTSD severity was significantly greater among those receiving acupuncture than in those receiving UPC. Acupuncture was also associated with significantly greater improvements in depression, pain and physical and mental health functioning. Pre-post effect-sizes for these outcomes were large and robust.
