Presently, acupuncture is a technique considered to be capable of stimulating the regulatory systems of the organism, such as the central nervous system, the endocrine system and the immunological system. The median frequency of the upper trapezium muscle with 40% and 60% of maximal voluntary contraction (MVC) of 15 healthy volunteers, was analyzed after the individuals were submitted to the AA treatment. The non-parametric Friedman test was used to compare median frequency values. In this exploratory study, the level of significance of each comparison was set to p<0.05. The intraclass analyses indicate a significant increase of the median frequency muscle at 60% of the MVC (Wicoxon test). Based on the results found, the AA peripheral stimulus can act as a modulator mechanism of muscle activity and was possible to verify correspondence of the auricular acupoint with the trapezius muscle.
