G-Trainer antigravity treadmill, from Menlo Park, CA based Alter-G, Inc., is now classified as a medical device, cleared by the FDA “for medical uses in rehabilitation after lower extremity injury or surgery, aerobic conditioning, weight control, gait training for neurological conditions, and strengthening and conditioning for older patients,” according to the company’s press release.
The device has more features than the computer in front of you, namely “an advanced air pressure regulation system, enclosure sealing component, a customized treadmill, and a touch screen control panel.”
From a G-Trainer brochure:
Alter-G has developed an advanced air pressure regulation system to ensure that body weight variables can be accurately set for every user, every time. The air pressure regulation system is sophisticated enough to monitor and account for changes to the interior pressure of the cavity so that accurate body weight reduction can be maintained throughout a workout session.
Users can choose to reduce their effective body weight by as much as 80% in as small as 1% increments. It takes very little pressure in the cavity to produce a substantial lifting force and because the pressure is distributed over a large surface area, the user feels very little force against their body.
