The clinical symptoms of frozen shoulder adhesions are mainly as follows: First, shoulder joint pain. For the initial adhesions around the shoulder joint, the patient will have obvious pain symptoms. If in severe cases, the shoulder joint pain will prevent the patient from resting and working normally. Secondly, the shoulder joint movement will be restricted. After the adhesions appear around the shoulder joint, it will restrict the range of motion of the shoulder joint, such as forward flexion, supination, abduction, internal rotation and external rotation movements. Third, local swelling of the shoulder joint. Since the shoulder joint cannot move normally, local blood circulation will be impaired, which will easily cause chronic swelling. Fourth, muscle atrophy around the shoulder joint. The range of motion of the shoulder joint is reduced, and because of the pain, the shoulder joint cannot bear weight normally, which will cause disuse atrophy of the muscles around the shoulder joint, such as the deltoid and rotator cuff muscles.
