What is the AlterG™?

The AlterG™ is the first FDA approved therapeutic treadmill that uses differential air pressure. It reduces the force of gravity on the mass of a runner or walker’s lower extremities.

The AlterG™ was developed for astronauts using NASA technology and was used as part of their exercise training programs to combat muscle atrophy.

The AlterG™ accelerates rehab
and athletic training.

The AlterG™’s exclusive unweighting technology provides numerous benefits and purposes for rehabilitation after surgery, athletic training for optimal performance or benefit the treatment of certain neurological conditions.


  • I suffer from MS and cannot walk for more than 10 minutes at a time without fatigue. With the AlterG, a half hour walk is no problem at all. It feels great to finally get pain free exercise, I couldn’t be happier.

  • My balance and stability have improved drastically! My legs have become much stronger since using this machine. I love the AlterG and wouldn’t hesitate to recommend it to friends and family.

  • The AlterG has helped me to improve my gate and has given me confidence. In my opinion it is a wonderful rehab device and I feel it should be available for use in every physiotherapy clinic.

  • After a nasty bout of septic arthritis and a 7 week stay in hospital I was told that my chances of walking again were very limited. After just a few months using AlterG I am now back on my feet and only use a cane for long distances. I couldn’t have done it without the AlterG and would recommend it to anyone looking for a speedy recovery.

  • After a session on the AlterG I feel less stiffness, minimized pain levels and I even feel more balanced and sure of my own footing. If I could use the AlterG everyday I’d be very happy!
