Alter-g uses patented differential air pressure technology to gently and precisely reduce gravitational forces on patients, allowing them to move without pain or interference to natural gait mechanics. AlterG can help shorten orthopaedic recovery times, manage neurological conditions and chronic disease, build strength and endurance while aging, and increase athletic performance.


Gently unweight patients from 100% to as low as 20% of their body weight in precise 1% increments for low-impact, pain-free movement

Unique technology allows for normal gait and balance unlike hydrotherapy or harnesses – 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
