according to the American Physical Therapy Association - Physical therapists are movement experts who improve quality of life through prescribed exercise, hands-on care, and patient education. Physical therapists diagnose and treat individuals of all ages, from newborns to people at the end of life. Many patients have injuries, disabilities, or other health conditions that need treatment. But PTs also care for people who simply want to become healthier and to prevent future problems. Physical therapists examine each person and then develop a treatment plan to improve their ability to move, reduce or manage pain, restore function, and prevent disability.
