FLEXOR DIGITORUM PROFUNDUS

• Origin

Proximal three-quarters of the ulna and interosseous membrane

• Insertion

Distal phalanges of fingers 2-5

• Agonist(s)

- Flexor pollicis longus

- Flexor digitorum superficialis

• Antagonist(s)

- None

• Function

Flexes fingers at distal interphalangeal joints

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 profundus 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 profundus.

• 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.
