Conduction velocities along course of ulnar nerve

Abstract

The left ulnar nerve was tested on 20 normal subjects on two occasions several weeks apart to determine the motor velocities along various points over the course of the ulnar nerve. Analysis showed that there is no practical difference between proximal and distal motor velocities of the normal ulnar nerve. An approximation of reduced velocity peripheral to the most distal stimulus point can be reflected in the residual latency calculation. Velocity determinations done with stimuli points closer than 10 cm and/or with stimuli at points where the nerve trunk is not superficial are subject to considerable error. residual latency; motor velocity of ulnar nerve; axonostenosis Submitted on October 15, 1963
