ABSTRACT

Introduction: The use of electric stimulation to situate peripheral nerves was introduced in 1962. The specific prospective answers are described for each stimulated nerve, but not for the intensity required to qualify a motor answer as being appropriate to apply the anesthetic solution, because this is carried out in a subjective way. Our objective is to propose an objective and quantifiable measurement in the different joint angles in response to the electric stimulation during the blockade of peripheral nerves. Design: It was measured each angle of the joints of the wrist, hand, foot and knee in order to evaluate the grades of movement of these joints when the motor nerves motors that innervate them through different mechanisms are stimulated. Results: It was found that joint movements smaller than 5 grades are not effective to lay the local anesthetic, since there is a weak answer. The optimum response goes from 10 to 15 grades that is a movement of moderate intensity which results in an appropriate analgesia. Conclusion: We propose a scale of evaluation of the answer motorboat for the joint movements and a second scale for the patellar movement.
