PALMARIS LONGUS

• Origin

Medial epicondyle of humerus

• Insertion

Palmar aponeurosis

• Agonist(s)

- None

• Antagonist(s)

- None

• Function

Tenses palmar aponeurosis, weakly flexes hand at the wrist

TRIGGER POINT(S)

• Location

Trigger points can be found along the length of the muscle, particularly in the mid-portion.

• Pain Referral Pattern

Pain may refer to the anterior aspect of the forearm and palm.

It can cause aching, burning, or sharp pain along the anterior side of the forearm, and may contribute to discomfort or weakness in wrist flexion.

• Potential Causes

• Overuse or repetitive activities involving wrist flexion, such as typing, gripping, or manual labour.

• Sudden movements or strains, especially during sports or physical activities.

• Poor wrist and forearm mechanics during activities.

• Muscle imbalances between the palmaris longus and other forearm muscles.

• Trauma or injury to the anterior aspect of the forearm or wrist.

• Prevention Tips

• Use proper techniques and ergonomic equipment during activities involving wrist flexion to avoid overloading the palmaris longus.

• Incorporate regular stretching and strengthening exercises for the forearm muscles.

• Ensure proper warm-up and cooldown routines before and after exercise.

• Gradually increase workout intensity to avoid sudden strain.

• Ensure balanced strength training to avoid muscle imbalances.
