Adhesive capsulitis refers to the gradual loss of shoulder ROM. The scapula and shoulder compensate, masking the motion and function loss.
There are three phases of this condition:
- Freezing is when pain and stiffness build gradually and cause progressive loss of range of motion,
- Thawing is when pain diminishes and moving the arm becomes more comfortable, but range is still limited,
- and Frozen is when some range of shoulder motion returns, but not to its original level.
It affects people between 40 and 60, usually, and women are more prone to getting it. It often takes months of therapy to resolve. When pain is severe, cortisone injections are often recommended.
