RESUMO

Abstract 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.
