Patients & Athletes

“AlterG has enhanced our ability to expedite certain phases of our rehabilitation protocols and has eliminated some of the unknowns that we used to face prior to returning to the playing surface.”

— Rod Martin, HATC, Oakland Raiders

“Greatest invention ever! It helped me run for the first time in almost a year. You couldn’t wipe the smile off my face the first time I ran in it. Love it, love it, love it.”

— Tammy Chapman, Patient

“Beyond helping runners, we found countless ways to integrate the Anti-Gravity Treadmill into a broad variety of patient care plans – to help them achieve better outcomes. Patients look forward to their next visit.”

— Bryan Graham, MPT, Oceanside Physical Therapy

“AlterG therapy really gives people opportunities they wouldn’t have otherwise.”

— Gregg Dahlgren, Family Physical Therapy And Sports Center

“The Anti-Gravity Treadmill has had quite an impact on our practice – considering both patient outcomes and clinical efficiencies. We have come to rely on it to help us provide exceptional care for a variety of patient conditions.”

— Kimberly Huey, PT, DPT, Elite Sports Physical Therapy (ESPT)

“I’ve suffered my whole life with congenital hip dysplasia. Typically I can’t walk more than a couple of blocks without intense pain. And I ran a mile today, for the first time in my life. Thank you!”

— Sammy Rose, Patient

“We’re seeing a greater range of patients and the AlterG has allowed us to treat patients earlier. Rather than 6–8 weeks post-op, we are now treating patients at 3–4 weeks post-op.”

— Bryan Nadeau, PT, Muir Orthopedic Specialists

“Having AlterG has been instrumental in both rehabilitation and the overall conditioning of our players. Beginning movement earlier in the rehab process has been critical to earlier returns to the court.”

— Aaron Nelson, MS, ATC-L, PES, CES, Phoenix Suns

How Does It Work?

The AlterG® Anti-Gravity Treadmill features patented, NASA Differential Air Pressure (DAP) technology, a precise air calibration system, based on the user’s actual body weight, to change what’s possible in rehab and training. Using a pressurized air chamber to uniformly reduce gravitational load and body weight in precise 1% increments, AlterG enables patients and athletes to move unrestricted and pain-free – restoring and building muscle strength, range of motion, balance, function, and fitness. No other unweighting technology offers as much precision, accuracy and comfort.
