Physical therapists are licensed health care professionals who have earned a master’s or doctorate degree in physical therapy. Physical therapists provide their services in hospitals, out patient facilities, schools, rehabilitation clinics, and home care centers. Physical therapists work to rehabilitate people who have sustained an injury, birth defect, disease or other pathological process that has interfered with the proper functioning and alignment of the musculoskeletal system. The physical therapist works directly with the patient, through a series of exercise and other physical therapy methods to rehabilitate the patient. Physical therapists focus on pain relief, healing and restoring function and movement to the afflicted area. Just as doctors do, physical therapists devote their entire professional career to rehabilitating their patients and preventing injuries. Typically, physical therapists are well versed in other associated areas such as diet and wellness.
