What is AlterG (Antigravity Treadmill)?

AlterG® develops trusted, leading-edge rehab and training equipment using NASA Differential Air Pressure technology. Our Anti-Gravity Treadmill™ technology empowers people to move in new ways and without pain – to recover mobility, improve wellness, and enhance physical performance. In fact, AlterG can be found in over 4000 facilities around the world and has helped millions to safely and consistently reach their goals and achieve better outcomes.

The AlterG® Anti-Gravity Treadmill™ integrates patented, NASA Differential Air Pressure (DAP) technology, a precise air calibration system, and real-time information to change what’s possible in rehab and training. Using a pressurized air chamber to uniformly reduce gravitational load and body weight in precise 1% increments, AlterG enables patients and athletes to move unrestricted and pain-free – restoring and building muscle strength, range of motion, balance, function, and fitness. No other unweighting technology offers as much freedom, control, and versatility.
