A comparable method with a different emphasis is currently the subject of a United States grant application by another group to formally test American War Veterans from Afghanistan and Iraq. The chief investigators (Assistant Professor Gerbarg and Associate Professor Brown) are collaborating with The Bay Pines Veterans Administration Medical Center in Florida to develop a study utilising a specific Yoga breathing technique called Sudarshan Kriya Yoga (SKY) for treatment of American veterans returning from Afghanistan and Iraq. Elements of this method have been widely tested on individuals suffering with Acute Stress Disorder and Posttraumatic Stress Disorder (Gerbarg and Brown 2005 Direct communication) and have been reported to have relieved posttraumatic stress disorder (PTSD) in large groups of people affected by mass disasters such as: war (Kosovo, Bosnia, Iraq and Sudan) (Biswas 2004; Joseph 2004; Luedemann 2004); terrorism (New York City 9/11) (Anonymous 2001b), (Kashmir, India, Israel); and natural disasters (Gujurat earthquake, Iran flood and the Asian Tsunami) (Gujurat earthquake, 2000) (Anonymous 2001a). Pilot studies conducted by the Principal Investigator using similar techniques showed positive health results for Vietnam Veterans with PTSD in Australia (Carter and Byrne 2004).
