OverviewSuggest Edit

AlterG, Inc. is dedicated to getting people moving. Everyday, AlterG® is researching, innovating and uncovering new technologies and applications of those technologies. From our exclusive, NASA-patented Differential Air Pressure unweighting technology used in our Anti-Gravity Treadmills® to the world’s first intuitive Bionic Leg, we’re delivering industry-leading innovation.

AlterG products and support are constantly being applied to shorten recovery times, reduce injury, and improve mobility for patients. At the same time, AlterG enables practitioners to develop new services and revenue streams.

Ultimately, AlterG is committed to creating and uncovering new technologies that help advance the possibilities for recovery, training and improved mobility. The Anti-Gravity Treadmills and industry-leading Bionic Legs are just the beginning.

Whether that means running a marathon or walking to the living room, our goal is to bring you products and technology to keep you healthy and on your feet.

Since AlterG founder Sean Whalen and his father developed the technology for the first Anti-Gravity Treadmill in their family garage, AlterG has sought to advance what’s possible during physical therapy and athletic training. That’s why, in May 2013, we incorporated the Bionic Leg as our second mobility enhancement product.

As a member of the physical therapy and athletic training communities, we love seeing our products used in a wide-variety of ways to improve patient outcomes and help athletes achieve personal bests.

We are committed both to the end users as well as the clinics, hospitals, and universities that use the Anti-Gravity Treadmill and the Bionic Leg in therapy and training. As a member of these communities, we are looking forward to future developments that continue to change the way physical therapy and sports medicine are practiced.
