Abstract

ABSTRACT: Introduction : Median and ulnar nerves are used in comparative electrophysiological studies. We analyzed the conduction values in these hand nerves in healthy volunteers to find any physiological differences between them. Methods : We performed standard conduction studies and conduction velocity distribution (CVD) tests with estimation of 3 quartiles in 31 healthy right‐handed volunteers (17 women, 14 men) with a mean age of 44.8 ± 15.5 years. Results : The conduction velocities in all quartiles of CVD tests were statistically faster in the ulnar nerve ( P < 0.00001), with no differences in the spread of conduction values and no differences between sides. In the ulnar nerve, CVD velocities in all quartiles were faster in the female group ( P < 0.05). Discussion : The ulnar nerve has more fibers conducting with high velocities than does the median nerve. Electrophysiological comparisons between hand nerves must be performed carefully.
