Rehabilitation therapy refers to therapeutic treatment patients receive after an illness or injury like cancer, stroke, or accident. Nationally, physical therapist assistants earn hourly wages between $14.62-$31.95 or $30,400-$66,460 annually depending on experience level. Rehabilitation therapists most commonly work in home health services, nursing care facilities, and hospitals and treat patients to regain strength, mobility, and fitness or for cardiac rehabilitation. Training requires an associate's degree from an accredited program and passing national and sometimes state exams for licensure.
