Brachioradialis Trigger Points - Dr. Jonathan Kuttner
The brachioradialis is part of the superficial group and forms the lateral border of the cubital fossa. It is typical for the belly of the muscle to be prominent when working against resistance.
The brachioradialis muscle works to flex the elbow and to help the extensors of the hand to bend the wrist up and back.
The brachioradialis is commonly over-used and over-worked, especially by those who utilize gripping in their occupation (or gym-rats). Active trigger points are common and will often induce pain that is misdiagnosed as tennis elbow.

Lower lateral end of radius, just above styloid process.
Flexes elbow joint. Assists in pronating and supinating forearm when these movements are resisted.
Radial nerve, C5, 6. BASIC FUNCTIONAL
