Classic history and presentation: Adhesive capsulitis typically follows a course of 3 phases. First (2-9 months), there is an insidious onset of pain that eventually becomes severe and disabling. The pain tends to be worse at night and stiffness gradually onsets. Second (4-12 months) is the contracture phase, which is characterized by stiffness and progressive loss of motion that interferes with activities of daily living. Pain typically improves in this phase. Third (5-24 months) is the recovery or "thawing" phase in which the symptoms gradually alleviate and there is an improvement in range of motion (ROM).
