Frozen Shoulder

Adhesive capsulitis is the stiffening of the shoulder due to scar tissue, which results in painful movement and loss of motion. The actual cause of adhesive capsulitis is a matter for debate. Some believe it is caused by inflammation, such as when the lining of a joint becomes inflamed (synovitis), or by autoimmune reactions, where the body launches an "attack" against its own substances and tissues.

Often called a stiff or “frozen shoulder,” adhesive capsulitis occurs in about 2% to 5% of the American population. It affects women more than men and is typically diagnosed in people over the age of 45. Of the people who have had adhesive capsulitis in 1 shoulder, it is estimated that 20% to 30% will get it in the other shoulder as well. Physical therapists help people with adhesive capsulitis address pain and stiffness, and restore shoulder movement in the safest and most effective way possible.
