About AlterG

Anti-Gravity Treadmill Technology

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.

“The AlterG took the fear out of returning to training. It enabled me to begin running six weeks before my doctor cleared me to run on the ground and allowed me to incrementally transition back to full training.”

How Different Air Pressure Works

In the AlterG system, users gently “unweight” themselves with positive air pressure to reduce gravitational forces on the body. All so they can move like never before to regain, maintain, and improve mobility, wellness, and performance
