INTRODUCTION: Physical therapy is used to minimize inflammatory process damage, and highlight the use of electrotherapy. Bernard's diadynamics is one of the possible resources, but with little evidence in the literature. OBJECTIVE: To analyze the effects of Bernard's diadinamics on nociception and edema in rats' tendon trauma. MATERIALS AND METHODS: The sample consisted of 18 Wistar rats divided into: control group (CG); negative pole Group (GP-); and positive pole Group (GP+). The animals had their right calcaneous tendon, injured with energy of 0.4 J. To assess nociception, we used the "von Frey" type digital analgesimeter, which was applied in the injured tendon, and to evaluate the edema, we used a caliper. The treatment was carried out with the current DF, CP and LP (3 minutes each), daily, for five therapies. RESULTS: For the assessment of nociception, a significant difference with the time post-injury, only the last two assessments in GP+. In the evaluation of edema was obtained returned to baseline values only for GP+. CONCLUSION: Only Bernard's diadinamics positive pole was effective in reducing nociception and edema in rats subjected to the calcaneous tendon trauma.
