Rotator Cuff Tendinitis (Shoulder Impingement Syndrome)


The rotator cuff is made up of four muscles; supraspinatus muscle, the infraspinatus muscle, teres minor muscle, and the subscapularis muscle. These are the dynamic stabilizers and movers of the shoulder joint and adjust the position of the humeral head and scapula during shoulder movement. This keeps your upper arm inside your shoulder socket. It also gives you the strength and motion to rotate and lift your arms.

Tendinitis of the rotator cuff; also known as impingement syndrome of shoulder occurs when the tendons are swollen or damaged. This usually occurs over time.


It can be caused by activities that requires extending the arm over the head, doing repetitive lifting, keeping the shoulder in one position over a period of time or sleeping on the shoulder every night. Pain may also develop as the result of a minor injury.
