Poor posture, rounded shoulders, anterior head carriage, cumulative trauma disorders, weight lifting, and injuries all affect the shoulder joints. Repetitive movement of the rotator cuff can lead to inflammation of the bursa (Bursitis) in the subacromial region. Pain causes restriction of movement which leads to frozen shoulder (adhesive capsulitis).
