Frozen shoulder is condition that can develop after a traumatic insult to the shoulder. The condition is defined by thre distinct phases. 1. Freezing - the shoulder is commonly sore and painful in this stage and there is progressive limitaion of movement particularly in internal and external rotation. 2. Frozen - the shoulder is stiff and limited in movement but pain is normally not  a major issue in this stage. 3 - Thawing - the shoulder begins to regain some of its lost range of motion. Frozen shoulder has been shown to be more common in individuals who have a history of diabetes and the reson for its development remains unclear. Maintaining range of motion during the freezing stage and improving range of motion though the later stages is important. Medical magement of the condition may complement physiotherapy.
