AlterG Treadmill

What is the AlterG Treadmill?

The AlterG Anti-Gravity Treadmill is a NASA designed anti-gravity device that allows patients and athletes to walk, jog, and run with reduced stress and impact. Using patented technology to control “differential air pressure,” the AlterG is able to support up to 80% of a person’s body weight. This allows patients to safely begin recovery sooner after an accident or surgery as well as the ability to slowly build to bearing more body weight as they progress through physical therapy.

How the AlterG Treadmill Works

The AlterG Treadmill system performs unloading (unweighting the body), and it also incorporates progressive loading to gradually allow the body to bear more weight on its own. By counteracting the effects of gravity, the AlterG Anti-Gravity Treadmill puts less stress on your bones, joints, and muscles. This lets you move farther and faster without pain, restriction, or fatigue. Patients find that with the AlterG Treadmill, physical therapy is (even more of!) an effective and rewarding experience.

Uses for the AlterG Treadmill

Offered at our Gresham SportsCare Physical Therapy location, the AlterG Anti Gravity Treadmill is used to by both patients and athletes alike. It is an effective method to treat injuries, rehabilitate orthopedic surgeries, and address balance concerns.

  • Plantar fasciitis
  • Achilles tendonitis/repair

Frequently Asked Questions

  • 1 Am I a candidate for the AlterG Anti-Gravity Treadmill?

    Anyone with an ankle, calf, leg, knee, or hip issue is a potential AlterG Anti Gravity Treadmill candidate…even if you have had surgery! The AlterG allows you to begin walking, jogging, or running earlier in your rehabilitation because your PT can decrease the stress on your body to accommodate your injury. Early weight bearing will speed your recovery and get you back to full activity sooner!

  • 2 How long is each session on the AlterG Anti-Gravity Treadmill?

    AlterG sessions are tailored to your injury status and needs. Sessions can be as short as 5 minutes or as long as 60 minutes. If you are early in your recovery, shorter sessions are best. If you are an elite athlete suffering from mild tendinitis, then you may be able to train for up to 60 minutes. Your PT will discuss what is appropriate for you after assessing your injury or condition at your evaluation.

  • 3 How long will my recovery take if I use the Alter G Anti-Gravity Treadmill?

    While exact recovery times will vary from patient to patient, being able to walk, jog or run earlier in your healing phase has the ability to shorten your recovery by days or weeks. This can give you an edge on your competitors or allow you to get back sooner to the activities you love most.
