How to evaluate extensor carpi radialis brevis strength with Manual Muscle Testing (MMT).

Extensor carpi radialis brevis (ECRB) is a short muscle emerging underneath the extensor carpi radialis longus and both muscles share a common tendinous synovial sheath. It is an extensor muscle located superficially at the posterior compartment of the forearm. It is the prime dorsiflexor of the wrist. Origin [edit | edit source]

To satisfy grade 5 'normal muscle' performance criteria, the patient must have the ability to move through complete range of motion (active resistance testing) OR maintain an end point range (break testing) against maximum resistance.
