Abstract
Electroneurography of the pudendal nerve is extremely important in the diagnosis of neurogenic fecal incontinence and a pudendal canal syndrome. The aim of this study was to determine pudendal nerve motor latency of the overall distance by stimulation of nerve root S3 by discharging a magnetic coil. This can be achieved by positioning an earth electrode between the site of stimulation and the registration electrode. We investigated 18 volunteers by this method. The average latency period was 2.51 milliseconds (SD = 0.32) on the right and 2.49 milliseconds (SD = 0.33) on the left side. This method enables precise diagnosis in neuropathies of the pudendal nerve more so than with conventional electric stimulation.
