Final answer:
True, physical therapy aims to relieve and reduce pain by improving physical function and addressing muscle and joint injuries. Therapists use heat, exercises, and support equipment to help heal and rehabilitate patients.
Step-by-step explanation:
True, one purpose of physical therapy is to relieve and reduce pain. Physical therapists work closely with patients to address muscle and joint injuries, and through various treatments and exercises, they help to improve physical functioning and reduce functional impairments. Initially, the therapy may involve applying heat to the injured area to promote blood flow and healing, followed by targeted exercises and possibly icing to decrease inflammation. These exercises are continually monitored to track improvements in muscle function including strength, balance, and endurance. Physical therapists are also adept at guiding patients on the correct use of supportive equipment, like crutches, to ensure safety and proper muscle recovery. Over time, the patient's strength and function are typically restored as the injury heals.
