The western pioneer of yoga as therapy, Richard Miller, has developed the use of Yoga nidra for rehabilitating soldiers in pain, using the Integrative Restoration (iRest) methodology. Miller worked with Walter Reed Army Medical Center and the United States Department of Defense studying the efficacy of the approach. According to Yoga Journal, “Miller is responsible for bringing the practice to a remarkable variety of nontraditional settings” which includes “military bases and in veterans’ clinics, homeless shelters, Montessori schools, Head Start programs, hospitals, hospices, chemical dependency centers, and jails.” The iRest protocol was used with soldiers returning from Iraq and Afghanistan suffering from post-traumatic stress disorder (PTSD). Based on this work, the Surgeon General of the United States Army endorsed Yoga Nidra as a complementary alternative medicine (CAM) for chronic pain in 2010.
