The shoulder is a ball and socket joint with a large range of movement. As such, it is quite susceptible to injury.
The shoulder consists of the upper arm bone, collarbone, and shoulder blade, along with muscles, ligaments, tendons, and nerves. Shoulder pain can be a result of injury or disease to any of these parts of the shoulder. The pain itself can be localized or may be deferred to areas around the shoulder or down the arm(s).
Injuries to the shoulder include sprain/strain, dislocation, separation, fracture, frozen shoulder, impingement, rotator cuff tear, tendonitis, bursitis, swimmers shoulder, clavical fracture, snapping scapula syndrome, and arthritis.
Physical therapy treatments for shoulder pain aim to reduce pain, restore normal joint function and improve muscle function.
