Magnetic stimulation of the pudendal nerve
1Department of Neurology, University of Saarland, Homburg, Germany.
Unlabelled:
Electroneurography of the pudendal nerve is extremely important in the diagnosis of neurogenic fecal incontinence and a pudendal canal syndrome.
Purpose:
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.
Methods:
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.
Results:
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.
Conclusion:
This method enables precise diagnosis in neuropathies of the pudendal nerve more so than with conventional electric stimulation.
