FLEXOR CARPI

ULNARIS

• Origin

Medial epicondyle of humerus and olecranon process of ulna

• Insertion

Pisiform bone and the base of the fifth metacarpal bone

• Agonist(s)

- None

• Antagonist(s)

- Extensor carpi ulnaris

• Function

Flexes and adducts 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 medial aspect of the forearm and wrist.

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

• Potential Causes

•Overuse or repetitive activities involving wrist flexion and ulnar deviation, 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 flexor carpi ulnaris and other forearm muscles

• Trauma or injury to the medial aspect of the forearm or wrist

• Prevention Tips

• Use proper techniques and ergonomic equipment during activities involving wrist flexion and ulnar deviation to avoid overloading the flexor carpi ulnaris

• 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.
