According to the American Academy of Orthopedic Surgeons, musculoskeletal problems were the number two reason for visiting your physician in 2003. Back pain was the most common complaint (31 million visits), followed by knee pain (19 million) and shoulder pain (14 million). Sprains or dislocations and fractures account for almost one-half of all musculoskeletal injuries. Many physicians prescribe physical therapy as treatment for these problems/injuries. Physical therapy helps reduce pain and inflammation, increase range of motion and strength through modalities, manual therapy and exercise.
