Frozen shoulder, also known as adhesive capsulitis, usually develops without any identifiable cause. It is a painful condition that almost universally results in decreased range of motion of the shoulder joint. It may develop gradually, preventing one from realizing the magnitude of the problem. On the other hand, the symptoms can be quite sudden and severe with nearly complete loss of shoulder motion. Adults in their forties and fifties are most at risk; however, anyone with a previous shoulder injury may be affected. Persons with a history of diabetes are at greater risk for adhesive capsulitis than are persons who do not have diabetes.
