Description:[edit | edit source]

It is the most superficial muscle on the radial side of the forearm. It forms the lateral side of the cubital fossa. It's often fused proximally with the brachialis. It has a thin belly descends in the mid forearm, where its long flat tendon begins, then the tendon continues to the radius.[1]

Origin:[edit | edit source]

Humerus (lateral supracondylar rigid) and lateral intermuscular septum.[1]

Insertion:
[edit | edit source]

Radius (just proximal to styloid process) [1]

Nerve:
[edit | edit source]

C5-C6 radial nerve  (C7 innervation sometimes cited)[1]

Artery:
[edit | edit source]

Function:
[edit | edit source]

Flexion of the elbow when the forearm is in midposition.

Clinical relevance[edit | edit source]

Assessment:[edit | edit source]

  • Palpation

Palpation will be on the proximal volar surface of the forearm

  • Muscle power

The MMT is usually done for the three main elbow flexors (biceps, brachialis and brachioradialis) by asking the patient to bend his/her elbow against resistance and start grading, but in try to focus on the brachioradialis, we will ask the patient to bend the the forearm with some degree of pronation (midposition) 

Note: the wrist flexor muscles should remain relaxed throughout the test, because strongly contracting wrist flexors may assist in elbow flexion. [1]

Treatment:[edit | edit source]

  • Strengthening exercise:

In supine, sitting or standing position and by having the forearm in midposition, slowly start bending with any suitable type and degree of resistance given by the therapist, such as dumbbells, sand packs or theraband.
