Total hip arthroplasty (THA) is a common surgical procedure among Veterans. It is most often used to treat hip osteoarthritis, which is more common among Veterans than the general population. Some patients continue to experience functional limitations after THA, and studies have shown that these patients still tend to put greater loads on the opposite leg, which can increase the risk of developing osteoarthritis in that leg. One likely reason for these post-surgical limitations is that rehabilitation is very minimal following this procedure. This project will involve development and preliminary testing of a functional movement retraining program, designed to help Veterans improve their function and biomechanics after THA. The project will also develop processes for delivering this program in Veterans' homes, to increase accessibility.
