Abstract

Introduction: Acupuncture is an ancient form of treatment used initially in China and is currently common practice in the West among health professionals in various clinical conditions according to the World Health Organization, causing local or remote biological responses. Objetive: This experiment aims to evaluate the influence of electroacupuncture on recovery of peripheral nerve through functional gait analysis and nociception after crush injury in the sciatic nerve in rats. Methods: Were included 30 Wistar rats, weight of 198g divided into three groups. Functional analysis was performed by the method of Functional Index Sciatic (FIS) by shooting the rear footprints performed on a mat with controlled rate in the days: preoperative; 7th day post-operation; 14 post-operation day and 21th day post-operation. In the same period the animals were evaluated for nociception using von Frey filaments. Results: From the results it was found that there was an improvement of the FIS in both treated groups compared with the control group. In the preoperative week there was no statistical difference (p> 0.05). The 1st postoperative week was no statistical difference (p <0.05) when comparing the three groups. In the 2nd week yielded the same characteristics of the first week (p <0.05). In the 3rd week there was reversal of the improvement in groups, and the G2 achieved better rates (p <0.05) than G3 and G1, G3 but was better than G1. In the analysis of nociception there was no statistical difference (p> 0.05). Conclusion: The electroacupuncture in both treated groups accelerated and improved nerve recovery of the animals according to the FIS.
