The loss of passive range of motion (ROM) is a critical element in establishing the diagnosis of a true frozen shoulder. Although conditions such as subacromial bursitiscalcifying tendinitis, and partial rotator cuff tears can be associated with significant pain and loss of active ROM, passive ROM is preserved. Therefore, patients with those conditions should not be classified as having a frozen shoulder.
