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.
ANTI-Gravity Treadmill ALTER G Gently unweighs patients from 100% to as low as 20% of their body weight in 1% increments for low-impact, pain-free movement. Unique technology allows for normal gait and balance for superior weight-supported walking, running, and closed kinetic-chain exercise. Real-time gait data, pain recording, and live video monitoring improve clinical decision-making on the fly with objective, measurable information and visual feedback for improved outcomes. Encourage movement and motor learning, and improve range of motion.
