The elbow's soft tissue restraints include 2 ligament complexes (medial and lateral collateral), 4 muscle groups (flexors, extensors, pronators, supinators), and 3 major nerves (radial, median, ulnar) and their branches.
We used the MMT to assess strength and function of select hand and wrist muscles (e.g., forearm supinators, wrist flexors/extensors, and finger flexors/extensors), for which scores range from 0 to 5, with a score of 0 for a subject with no movement or excitation and a score of 5 for a subject able to hold a position against test-applied resistance.
