Exclusive electrophysiological motor involvement in carpal tunnel syndrome.

Objective: To define the frequency of exclusive electrophysiological motor involvement in carpal tunnel syndrome (CTS).

Methods: We reviewed the electrophysiological studies of 2727 consecutive hands with typical symptoms and signs of CTS and at least one abnormal test of the following: median distal motor latency (DML), digit two sensory conduction velocity (D2-SCV), segmental D2-SCV from wrist to palm, median-ulnar sensory latency difference from ring finger stimulation.

Results: Thirty-one hands (1.
