The origins of IRI and iRest are deeply tied to the service and support of the US Military. In 2006, the Department of Defense conducted research at Walter Reed Army Medical Center (WRAMC) on the efficacy of Yoga Nidra (an ancient meditative practice dating back to 2500 B.C.E.). Renamed Integrative Restoration, or iRest for short, the protocol was developed and led by Richard Miller, PhD. The study was conducted with soldiers returning from Iraq and Afghanistan experiencing post-traumatic stress disorder (PTSD). In June of 2010, iRest was endorsed by the US Army Surgeon General and Defense Centers of Excellence as a complementary and alternative medicine (CAM).
Following the 2006 study, the Deployment Health Clinical Center (DHCC) at WRAMC integrated the iRest protocol into its weekly treatment program for soldiers. iRest programs were subsequently set up at VA facilities in Florida, Kentucky, Ohio, North Carolina, Washington, DC, Illinois and Tennessee. iRest is currently supporting active duty, veterans and families of service members in over 50 veterans administration hospitals and military bases/hospitals across the United States.
