A frozen shoulder can be a source of shoulder pain. Shoulder rest (e.g. with the use of an arm sling) for a certain period of time can shrink the joint capsule of the acromiohumeral joint, which is the proper shoulder joint. This is called “frozen shoulder” or “adhesive capsulitis” and leads to pain and a markedly decreased range of motion in the shoulder joint.
Patients are severely distressed by this and tend to brace their arm along the chest cage and do not want to move it, which in turn makes the problem even worse. Frozen shoulder treatment consists of early physiotherapy treatment. Range of motion exercises and stretching of the shoulder muscles often allows the condition to subside gradually.
Long recovery time an different stages of frozen shoulder
However, it often takes its course and the condition can take 1.5 and often up to 2 or 3 years to resolve.
It has different stages where the range of motion is getting worse for a few months, then it stays stable, but markedly restricted and with persistent slow stretching exercises and active exercises within the range of motion, considerable shoulder range of motion and shoulder strength can be regained. Perhaps 80% to 85% of people affected with this condition will regain all of the strength and range of motion. However, there are other cases where shoulder disability remains (Ref. 3).
