Rehabilitation typically focuses on restoring the function of the pectoralis minor, coracobrachialis, and biceps short head to ensure proper scapulohumeral rhythm. This muscle is a weak flexor and adductor of the arm at the shoulder joint.
Understanding Coracoid Process Muscles in Functional Movement
It is a powerful flexor of the elbow and a supinator of the forearm, but its coracoid origin also contributes to shoulder joint stability, particularly during lifting and pulling motions. The coracoid process is a small, hook-shaped bony projection on the scapula, and several key muscles attached to coracoid process play vital roles in stabilizing and moving the shoulder joint.
This structure acts as a pivotal anchor, influencing the leverage and function of the muscles attached to it, which in turn affects the stability and range of motion of the entire shoulder girdle. Its tendon inserts directly onto the medial surface and superior border of the coracoid process.
How Coracoid Process Muscles Support Functional Movement and Shoulder Stability
These muscles work in concert to enable flexion, adduction, and internal rotation of the humerus, while also providing structural support to the glenohumeral joint from the front. This muscle acts as a downward stabilizer of the scapula, drawing it forward and downward against the thoracic wall.
