Alter G Anti-Gravity


AlterG Anti-Gravity Treadmills with patented Differential Air Pressure technology are leading the revolution in unweighting therapy. With more freedom, greater precision, and broader application, AlterG enables people to move in ways they could never have imagined. All to recover, maintain, and enhance physical function for better mobility, health, and performance.

Anti-Gravity Treadmills® with Differential Air Pressure Technology

AlterG Anti-Gravity Treadmills use innovative Differential Air Pressure (DAP) technology that enables unprecedented unweighting therapy and training capabilities. A pressurized "anti-gravity" chamber counteracts gravitational forces, gently adjusting body weight from 100% down to as low as 20% with unparalleled precision. This uniform lifting force reduces impact, pain, and effort. All while supporting normal gait and balance - and encouraging full, free range of motion and natural movement.


VIA The all-new Via® Anti-Gravity Treadmill® from AlterG® provides your patients a rehab and training experience unlike ever before. Available in two models, the 400 for physical therapy rehabilitation applications, and the 400X for more intensive sports training applications. Both feature DAP technology, integrated, real-time Stride Smart gait analytics, and built-in digital video monitoring.
