CORACOBRACHIALIS

• Origin

Coracoid process of scapula

• Insertion

Medial surface of humerus (mid-shaft)

• Agonist(s)

- Biceps Brachii

- Pectoralis major

• Antagonist(s)

Triceps Brachii

• Function

Flexes and adducts arm at shoulder joint

TRIGGER POINT(S)

• Location

Trigger points in the coracobrachialis are typically located in the upper part of the muscle, near its origin at the coracoid process of the scapula, and along the muscle belly.

• Pain Referral Pattern

Pain often refers to the front of the shoulder, down the upper arm, and occasionally into the forearm.

Pain can also be felt on the back of the upper arm and into the hand, mimicking symptoms of shoulder impingement or bicipital tendinitis.

• Potential Causes

• Overuse or repetitive activities involving shoulder flexion and adduction.

• Carrying heavy objects, especially in front of the body.

• Poor posture, particularly with rounded shoulders.

• Direct trauma or strain to the upper arm.

• Muscle imbalances between the coracobrachialis and other shoulder muscles.

• Prevention Tips

• Use proper techniques during lifting and carrying activities to avoid overloading the coracobrachialis.

• Incorporate regular stretching and strengthening exercises for the coracobrachialis and surrounding muscles.

• Maintain good posture and shoulder alignment, especially during upper body activities.

• Gradually increase workout intensity to avoid sudden strain.

• Ensure balanced strength training to avoid muscle imbalances.
