Orthopedic physical therapists diagnose, manage and treat disorders and injuries of the musculoskeletal system. They also help people recover from orthopedic surgery. This specialty of physical therapy is most often found in the out-patient clinical setting. Orthopedic therapists are trained in the treatment of post-operative joints, sports injuries, arthritis and amputations, among other injuries and conditions. Joint mobilizations, strength training, hot packs and cold packs, and electrical stimulation are often used to speed recovery in the orthopedic setting. Those who have suffered injury or disease affecting the muscles, bones, ligaments or tendons of the body may benefit from assessment by a physical therapist specialized in orthopedics.
