Abstract

SOMENSI, Danusa Neves et al. Does the type of electrode affect the electromyoneurographic parameters in rats?. Acta Cir. Bras. [online]. 2019, vol.34, n.3, e201900304.  Epub Mar 18, 2019. ISSN 1678-2674.  http://dx.doi.org/10.1590/s0102-865020190030000004.

Purpose:

To evaluate if the type of electrode (needle vs. surface) affects the electromyoneurography parameters in rats.

Methods:

Twenty male rats were anesthetized, then compound muscle action potential were recorded using a Neuropack S1 MEB- 9400©. All animals were submitted to two electroneuromyography analysis: first with surface electrode and then by needle electrode. We evaluated the latency, amplitude, duration and area of the negative peak of the gastrocnemius and cranial tibial muscles.

Results:

There were no significant differences between the groups in the mean of duration, latency, amplitude or area of the negative peak in gastrocnemius and cranial tibial muscles.

Conclusion:

The type of electrode does not affect the electroneuromyography parameters.
