BICEPS BRACHII

• Origin

Short head: coracoid process of scapula

Long head: supraglenoid tubercle of scapula

• Insertion

Radial tuberosity of radius, bicipital aponeurosis

• Agonist(s)

- Brachialis

- Brachioradialis

• Antagonist(s)

Triceps Brachii

• Function

Flexes elbow joint, supinates forearm, assists in shoulder flexion and abduction

TRIGGER POINT(S)

• Location

Trigger points in the biceps brachii are commonly found in the belly of the muscle, particularly in the middle third of the upper arm and near the musculotendinous junctions at the shoulder and elbow.

• Pain Referral Pattern

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

Pain can be felt deep in the shoulder joint and can mimic bicipital tendinitis.

• Potential Causes

• Overuse or repetitive activities involving elbow flexion or forearm supination.

• Heavy lifting, especially with improper technique.

• Poor posture and shoulder alignment.

• Direct trauma or strain to the upper arm.

• Imbalance between biceps and triceps strength.

• Prevention Tips

• Use proper lifting techniques and avoid overloading the biceps.

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

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

• Gradually increase the intensity of workouts to avoid sudden strain.

• Ensure balanced strength training to avoid muscle imbalances.
