ACTION: humeral abduction, internal rotation, external rotation
REFERRAL: shoulder

COMMENTS: The deltoid wraps the shoulder joint. The anterior deltoid pull the humerus towards the front, the lateral deltoid helps with abduction, and the posterior deltoid pulls the humerus posteriorly. The deltoid is usually involved in shoulder injuries. Although not part of the rotator cuff muscles, the deltoid almost always is strained when these muscles are strained. The deltoid is ropey on most people, and so static pressure on areas of inflammation or frictioning are good ways to work specifically. You can work broadly using your forearm as shown in the DVD Deep Tissue & Neuromuscular Therapy, the Extremities.
