Dr. Purcell is also and advocate of Aviation Testing. He has tested his products in situations where the vestibular system is stimulated. These records help Dr. Purcell better understand how vestibular inputs and/or lack of somatosensory inputs play a role in maintaining balance in the pathological patient. Dr. Purcell sees private and commercial pilots in both the public and military sectors. The pilots present from all over the US, Russia, China, Switzerland, Germany, England, Bulgaria, Czech Republic, Africa, and South America. He has a unique ability to understand a pilot's balance complaints because of his extensive experience on unique aerospace flight platforms including Bi-Planes, several advanced soviet jet warbirds including: MiG-215, Mig15UM, MiG-17 Fresco-A, MiG-21UM, and MiG-21M, KC-135, Skydiving, and Jetpack development.
Dr. Purcell has over 40 years experience in aviation and 27 years experience in NASA and Bell Aerospace flight platforms. He previously imported, and restored to airworthy condition, several advanced soviet jet warbirds including: MiG-215, Mig15UM, MiG-17 Fresco-A, MiG-21UM, and MiG-21M. His keen interest in aviation and aerospace has promoted research in his clinic for better ways to treat vertigo and complex vestibular disorders and to derive advanced vestibular therapy protocols now used at various rehabilitation facilities in California and now throughout China. Dr. Purcell and his team have designed and built multiple Jet Packs, Rocketbelts, and Xjets to better understand how vestibular inputs and/or lack of somatosensory inputs play a role in maintaining balance in the pathological patient. He also uses the devices to promote practice awareness to patients and physicians in the community. Dr. Purcell's Rocketbelt has been featured in movies. airshows, Formula One races, the 2012 Olympics, and hospitals in over 17 countries throughout the world.
Dr. Purcell also has developed a very unique home vertigo recording goggle called the "DizzyDoctor System". This goggle is to be used by a patient experiencing Vertigo in a home or out of clinic environment. It is a very robust recording unit and has been designed and tested in multiple unique environments including extreme sports and aviation. He has tested it in various unique situations and has collected and published eye movement data. This data has not only been collected in the home but also in yaw and pitch environments such as helicopters.
