Leaders in Anti-Gravity Rehab & Training
Founded in 2005, AlterG® leads the way in developing transformative technology that inspires and empowers people to achieve their physical aspirations. We use unique gravity-defying technology to redefine what’s possible in physical rehabilitation and training. Our Anti-Gravity Treadmill™ systems augment physical deficits and increase mobility to improve orthopedic rehabilitation, the management of neurological and chronic conditions, active aging, and athletic performance.

Built On Innovation
AlterG’s patented Differential Air Pressure (DAP) technology was originally developed for NASA. As astronauts were spending increasing periods of time in a zero-gravity environment, an unintended consequence emerged – a loss of weight and bone density.

An ingenious NASA engineer sought a solution to help astronauts maintain their strength and bone density while in space by using a pressurized air chamber to simulate gravitational load. Recognizing that the converse reduction of gravity’s effects on people on earth could have significant benefits in a vast array of applications, the solution was reverse engineered to create the Differential Air Pressure system used in the AlterG Anti-Gravity Treadmill today.

Changing Lives
By reducing the barriers to mobility and exercise using Anti-Gravity Treadmill technology, AlterG is empowering more people than ever to achieve their aspirations for a quality of life they may have never thought possible.

In the U.S. alone:

1/3 of the population (107+ million people) has a mobility impairment.
27 million people experience osteoarthritis.
100 million people experience chronic pain.
79% of runners get injured.
35% of adults are obese.
1 million people are living with Parkinson’s.
800,000 strokes per year.
700,000 knee replacements are performed each year.
332,000 hip replacements are performed each year.
