FLEXOR DIGITORUM SUPERFICIALIS

• Origin

Medial epicondyle of humerus, coronoid process of ulna, and radius

• Insertion

Middle phalanges of fingers 2-5

• Agonist(s)

- Flexor carpi radialis

• Antagonist(s)

- None

• Function

Flexes fingers at proximal interphalangeal joints and 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 fingers.

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

• Potential Causes

• Overuse or repetitive activities involving finger 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 flexor digitorum superficialis and other forearm muscles

• Trauma or injury to the anterior aspect of the forearm or fingers

• Prevention Tips

• Use proper techniques and ergonomic equipment during activities involving finger flexion to avoid overloading the flexor digitorum superficialis

• 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.
