When examining the hand, it is always important to document assessment of the ulnar, median, and radial nerves.
The motor function of the hand can quickly and simply be assessed with the following examination techniques:
Ulnar motor function >> Ask patient to first turn hand prone and spread fingers apart to a maximal distance. Then, ask the patient to resist your attempts to squeeze the fingers together.
Median motor function >> Ask patient to touch the distal tip of the thumb to the distal tip of the fifth finger and hold it. Then, attempt to pull the two fingers apart and ask patient to resist.
Radial motor function >> Ask patient to extend the wrist (i.e. as if trying to stop traffic) and push back against you attempting to push the hand into the flexed position.
