Abstract

The electroacupuncture is a commonly used resource for pain relieving, despite the restrict number of studies evaluating its effectiveness. This work includes two chapters, the first Electroacupuncture and the muscle pain threshold: a review, consisted of a literature critical review regarding the effectiveness of electroacupunture on the muscular pain treatment. The electronic database researched was ISI, Pubmed, Scielo, Scopus, Cochrane, Bireme from 1977 to January 2010, for articles containing the key words electroacupuncture AND muscle AND pain. Although the methodological differences raise difficulties to the analysis of their results, all the evaluated articles considered the method as efficient. Neither regarded the menstrual cycle influence at the pain threshold, nor the effect obtained along the treatment, presenting only the before and after the entire treatment effect. The second chapter, Electroacupuncture for myofascial pain in the upper trapezius muscle, purposed to evaluate the effects of electroacupuncture as a treatment to the upper trapezius myofascial pain on a longitudinal study. The efficacy of the treatment was evaluated in terms of pain intensity using the visual analog scale (VAS), the pressure pain threshold (PPT) by algometry, electromyography (EMG) and the SF-36 questionnaire. The occurrence of influencing factors in the sessions was monitored as was the menstrual cycle of each participant. It was observed both immediate and cumulative effect specially after the third session. The menstrual phase seems to be related to the increase of pain threshold observed on the sixth session. The EA was shown to be a reliable method for pain relief in the trapezius muscle at the evaluated sample. (AU)
