Physical therapy assists your body to make a complete recovery and restore you to full function. This is accomplished by designing a very specific treatment program for the injured area. A physical injury damages your muscles, nerves, ligaments, cartilage, tendons, and blood vessels. It is a big challenge for your body to restore everything back to normal. In fact, the repair process may not be fully completed. Even if the pain is gone, you may develop scar tissue, adhesions, or a weak tissue structure that is susceptible to re-injury.
