The AlterG, in most aspects, looks and works like a regular treadmill. Originally conceived by Dr. Robert Whalen to design effective exercise regimens for NASA’s astronauts, Differential Air Pressure (DAP) technology has been adapted by AlterG for use in training and rehabilitation. Cleared by the FDA in 2008, the AlterG Anti-Gravity Treadmill is a medical device that can be used for:


  • Lower body injury & surgery rehabilitation
  • Rehab after total joint replacement
  • Neurologic and balance retraining
  • Gait training in neurologic or unsteady patients
  • Strengthening & conditioning in older patients
  • Aerobic conditioning
  • Weight control & reduction
  • Sport specific conditioning programs
  • Stress related injury
  • For Athletes
  • For Trainers
  • For Performance Enhancement


AlterG Anti-Gravity Treadmill

Un-weighting is achieved in the AlterG by using air in a pressure-controlled chamber to gently lift the user. Precise calibration using our patented technology allows for very specific un-weighting from 100-20% of the users body weight in 1% increments, making it very safe for orthopedic rehabilitation. If you need to do 25% weightbearing, you can now do that with a normal walking pattern!

Something no other un-weighting modality can do!

How Does it Work?

The AlterG Anti-Gravity Treadmill creates a lifting force that allows for ultra-low impact.  Once you are fit on the machine, the belt starts moving and you’re free to adjust the speed and incline, as on a regular treadmill.  Only now, you can also control how much of your weight you want to feel. You can reduce your weight to about 20 percent, roughly the same sensation astronauts experience on the moon. At 50% unweighting, running has the same joint impact as walking!

With less gravity to fight, exercise becomes pain free.  The strain on your knees, hips and lower back disappears, making it easy to maintain mobility and range of motion.  This will allow ease and comfort while walking or running, while reducing the amount of impact on your joints. 

For people with weakness, balance problems, arthritis, or other limitations, the Alter G brings exercise to a level that works for them! We have people running for the first time in their lives in their 80's, and wheelchair bound kids walking for the first time in years. 

If you’ve suffered an injury or gone through surgery, you know the recovery process can be long and challenging. Whether you’re a professional athlete or a weekend warrior, a senior citizen or a young competitor, the AlterG Anti-Gravity Treadmill can help optimize your treatment outcomes to get you back faster to the activities you love.
