| Abstract: | Abstract
Background:
The aim of this study was to investigate the inter- and
intraindividual variability of the pudendal nerve terminal motor
latency (PNTML) in healthy volunteers to evaluate the
reproducibility of this method.
Probands and
Methods:
Eleven young healthy probands underwent measurements of
PNTML on 2 different days within an interval of 2 months three
times a day (morning, noon, evening) under absolute standardized
conditions. The examinations were performed by one
investigator.
Results:
Values of 2.1 ± 0.3 ms were measured for the right
pudendal nerve and of 2.0 ± 0.3 ms for the left side. Low inter-
and intraindividual variability was found with median changes
between 7.4% and 16.7% and between 0% and 12.5%, respectively.
Morning values were reproducible on the right as well as on the
left side, whereas noon and evening values differed
significantly.
Conclusion:
To get reproducible results we conclude that the
measurement of PNTML should be performed in the morning |
