Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Percutaneous electrolysis is based on the application of a galvanic current through an acupuncture needle. The underlying mechanisms that explain the efficacy of this technique are not completely well understood. The objective is to delve into the neurophysiological analgesic effects of percutaneous electrolysis. Participants will be assigned to one of three intervention groups. The analgesic effects of the technique will be evaluated by means of variables related to endogenous pain modulation.
