Alter G
Tech. Sgt. Jesse Myers, 92nd Medical Group Physical Therapy and Orthodontics flight chief, shows Lauren Buyer, 92nd MDG physical therapist, how to operate and use all the features of the "Alter G" treadmill April 20, 2017 at Fairchild Air Force Base, Washington. The Alter G treadmill uses a pressurized chamber on the lower body to create buoyancy, lessening the impact of the user's steps and allowing running to be less painful.
