The purpose of physical therapy is to help the patient return to active life as quickly as possible. Therapy strives to reduce pain, increase flexibility, range of motion, and function, build strength, and correct posture. Physical therapy is often prescribed for patients following spine surgery, to treat soft tissue trauma, nerve inflammation/injury, muscle spasms, fractures, arthritis, and many other problems. Patient education is an important component in physical therapy. Patients learn how their spine works, proper body mechanics, common disorders and their causes, benefits of good posture, importance of physical fitness and its relationship to injury and disease prevention.
