AlterG Therapy and Training

Individuals who have gone through joint replacement, suffered muscle or bone damage, or have a degenerative joint disease, often have limited mobility and function, pain, and other complications. AlterG’s Anti-Gravity Treadmill provides orthopedic rehabilitation for a large variety of conditions that affect the lower body skeletal and muscular systems. Injuries involving the lower back, hips, knees and ankle joints can be treated with the Anti-Gravity Treadmill. A rehab treadmill is often what is needed post-surgery to aid in the healing process for patients who have had total hip or knee replacement, ankle reconstructions, or other operative procedures.

The AlterG is very simple to use, making it a joy for patients to incorporate into their treatment programs. The ability to integrate physical therapy exercises early on in rehab sessions makes The AlterG an effective tool in assisting with restoring lower extremity range of motion and normalizing gait mechanics. After an evaluation, the physical therapist will schedule the Anti-Gravity Treadmill training sessions based on each patient’s specific needs. The AlterG physical therapy equipment can be used throughout the recovery process, providing benefits in each stage of rehabilitation.

The advantage of the AlterG Anti-Gravity Treadmill is its ability to allow you to be mobile at a fraction of your body weight. By doing this, you can dial in exactly where the pain stops and movement feels good again. This, in turn, gives the patient the opportunity to increase the rate of muscle conditioning and decrease total recovery time.

Studies have shown that using the AlterG Anti-Gravity Treadmill allows individuals to shorten recovery time. Research also indicates that an early start to rehabilitation can optimize functional gains.   


Unleash your body’s potential with the AlterG® Anti-Gravity Treadmill®
Get the results you want by having a more comfortable and effective training and exercise tool using patented NASA body weight support technology. “The AlterG is the most significant advance in training equipment for distance runners in the last half century.”

With the groundbreaking AlterG Anti-Gravity Treadmill, you can experience cardiovascular and lower body training like none other. Whether it’s practicing walking, trying to lose weight or training harder, the AlterG maximizes effectiveness by:

  • Enabling adjustable impact while walking or running
  • Allows for gradual progression of exercise
  • Minimizing the jarring forces that can lead to injury

WHAT DOES THE ALTERG DO? NASA patented Differential Air Pressure technology, the AlterG: comfortably supports you and “unweights” you by as much as 80% (adjustable in 1% increments). This uniquely adjustable unweighting can accomplish so much:

  • Significantly and precisely reduces ground reaction forces
  • Helps minimize discomfort and encourages movement
  • Creates a safe environment to work on technique
  • Allows for an increase in training volume with less impact


The leading choice to get the body moving and keep the human machine functioning optimally. Elite athletes, professional sports teams and top facilities have chosen the AlterG as an essential component of their training and recovery programs. From world class marathoners to the LA Lakers, the Chicago Bears to the Boston Red Sox, trainers and sports medicine professionals use the AlterG to get out-of-this-world results. Nothing compares to the Anti-Gravity Technology of the AlterG.

“I think it’s the best piece of equipment made for
running in the last 30 years, the most revolutionary
piece of equipment, without a doubt!”

“The AlterG anti-gravity treadmill is, in my opinion, the single most important running-related invention in history. We are keeping our runners running (most of them) while rehabilitating them, we are getting them better faster, we are allowing them to return after injury at the levels they were before injury (no loss in fitness), we are increasing strength and tolerance to activity in a quantifiable way…”
