![]() Whalen designed a treadmill with an air chamber (bag or enclosure) that surrounds the lower half of the body. This concept of DAP in space was brought down to Earth with the goal of creating the opposite effect – to allow people to experience less gravity and thus reduce stress on bones and joints. Whalen saw the potential for this technology to not only create additional gravity for astronauts in space but also reduce the effect of gravity for users on earth. As time went on and his research progressed, Dr. Whalen proposed that differential air pressure could have the same effect by applying a force equal to the astronaut’s body weight as a more comfortable and effective alternative to the harness. To combat this loss of bone density and muscle mass, they would typically use a harness system attached to a treadmill to add weight in order to walk. ![]() In space, lack of gravity causes astronauts to lose bone density and muscle mass. Whalen hypothesized that “musculoskeletal maintenance in space requires Earth-equivalent functional loading (or weighting).” This functional loading essentially involves loading the body with a force similar to that which you would experience on Earth. Working at NASA in the 1990’s to help astronauts maintain their bone density, muscular strength, and cardiovascular fitness while in space, Dr. This stems from a concept sometimes called Differential Air Pressure (DAP) technology originally developed by our founder’s father, Dr. Read Greatist.Boost microgravity treadmills are equipped with a unique air pressure technology that creates an environment where the user has the ability to change the effect of gravity they are experiencing. Without the AlterG, I'm not sure I'd have the courage to try running again, but it's an activity I love! Thanks for helping me get my running legs back!" Marcie Jannetti Today, I ran for 20 minutes at 100%! I have not done that since October 2013 when I finished my 2nd marathon. Each week I added 5%, inching closer to my goal. Starting at 40%, I gingerly began running. "The AlterG is amazing! In March when I started, I had to goal to run again after hip surgery in June 2014. It is safe, effective and FDA cleared and covered by many health insurance plans. AlterG rehabilitation treadmills offer the most advanced anti-gravity approach to physical therapy based on “unweighting” technology. Most lower extremity rehabilitation programs stress the importance of becoming mobile as soon as possible. You can read more about our medical findings in our clinical rehabilitation data About Alter-G section. This revolutionary medical rehab equipment is used and recommended by leading physical therapy clinics, hospitals, colleges and pro sports teams. AlterG’s exclusive precision gives patients the ability to set the exact point where exercise becomes pain free and provides clinicians a way to accurately measure patient rehabilitation About Alter-G progress. Unlike the simple lift harness devices, AlterG rehabilitation treadmills incorporate differential air pressure technology developed by NASA and enhanced by AlterG to provide precise unweighting in one percent increments to as low as 20 percent of the patient’s body weight. Strengthening and conditioning in older patients. ![]() Gait training in neurologic patients (Parkinson's, Multiple Sclerosis).Rehabilitation after total joint replacement.Rehabilitation following injury or surgery of the lower extremity (hip, knee, ankle or foot).The Anti-Gravity Treadmill® is FDA-cleared for the following functional rehabilitation About Alter-G indications:. ![]()
