Physical Medicine and Rehabilitation (PM&R) is a branch of medicine that focuses on restoring optimal function to people with physical impairments or disabilities. It is a multidisciplinary field that combines medical, surgical, and rehabilitative techniques to help patients regain their physical abilities and improve their quality of life. PM&R physicians, also known as physiatrists, use a variety of treatments, including physical therapy, occupational therapy, speech therapy, and medications, to help patients recover from injuries, illnesses, and disabilities.
