Trigger points in the supraspinatus

The supraspinatus is a muscle of the rotator cuff. Is sits above the infraspinatus and originates on the supraspinous fossa of the scapula. It’s insertion point is the superior facet of the greater tubercle of the humerus. It’s main function is to abduct the arm at the glenohumeral joint working with the deltoid. All rotator cuff muscles act to secure and support the head of the humerus in the glenoid fossa during arm movements acting as a sling. This muscle often gets impinged during overhead movements such as painting a ceiling. When trigger points form in this muscle they primarily refer a deep achy pain into the mid deltoid area with spillover pain radiating down the arm into the elbow.
