AlterG
US medical device company making Anti-Gravity Treadmills using NASA air-pressure technology for physical therapy; acquired by ReWalk Robotics in 2023.
AlterG, Inc. is a Fremont, California-based medical device company founded in 2005 by Sean Whalen. The company is known for its Anti-Gravity Treadmill, which uses patented NASA-derived Differential Air Pressure (DAP) technology to reduce a user's effective body weight in precise 1% increments from 100% down to 20%. The FDA first cleared the technology in 2008 under the name G-Trainer.
AlterG's primary rehabilitation products include the M320 and F320 Anti-Gravity Treadmill models, used in physical therapy clinics, hospitals, and athletic training facilities for post-surgical recovery, neurological gait training, and conditioning. The company later acquired the Bionic Leg from Tibion Corporation, an exoskeleton device that detects weight shifts and provides assistive force for patients recovering from stroke or lower-limb injuries. AlterG's technology serves rehabilitation centers, sports medicine clinics, and senior care facilities.
In August 2023, Israeli rehabilitation robotics company ReWalk Robotics completed its acquisition of AlterG for approximately $19 million.
