Ulnar nerve conduction velocity as function of wrist position.
Ulnar nerve conduction velocity (CV) calculated across the elbow has been shown to be significantly influenced by the position of the elbow. This study investigated the effect of wrist position on ulnar nerve CV in 19 control subjects. Ulnar nerve CV was determined with the elbow flexed at 90 degrees at two different wrist positions. The below-elbow-to-wrist CV was not significantly different between the wrist extended and the wrist flexed. Similarly, the mean across-elbow CV with wrist extended was not significantly different from the CV with the wrist flexed. The authors conclude that wrist position does not affect the calculated ulnar nerve CV across the elbow.
