  • AlterG Anti-Gravity Treadmill in Acute Rehabilitation of Total Knee Replacement

    This study is about using the Alter-G Anti-gravity Treadmill as part of the rehabilitation of patients who have undergone total knee replacement surgery. We hope to learn about the potential of this device to improve rehabilitation outcomes and everyday physical function when used in addition to standard of care rehabilitation. In addition to a lengthy recovery process, trauma from surgery and limited movement of the knee result in atrophy and breakdown due to a catabolic state and reduced anabolism of skeletal muscle proteins. Furthermore, total knee replacement surgery can result in weeks of immobilization of the knee. Immobilization of the knee can lead to atrophy and altered bone density. One possible method to speed the recovery process may be the complementary use of the AlterG anti-gravity treadmill in conjunction with standard rehabilitation procedures which can decrease the loss of muscle mass, strength and bone mineral density. The AlterG anti-gravity treadmill is a technology pioneered by Dr. Robert Whalen which utilizes a pressure controlled chamber to provide lift to the user in 1% body weight increments ranging from 100% to 20% of total body weight. This allows the user to run or walk on the treadmill at a reduced body weight, limiting impact on joints while allowing for a normal range of motion and gait.
