The objective this paper was to study 50 patients with fibromyalgia according to the American College of Rheumatology 1990 criteria with the following objectives: l) The frequency of several clinical symptoms in this group, comparing them with the literature; 2) The presence of a depressive symptoms together with fibromyalgia at the moment of the examination using the Beck depression questionaire; 3) To verify tests such as: erytrocyte sedimentation rate, bloodcount, latexfixation test, antinuclear antibodies, electrophoretic proteinogram, glutamic oxalacetic and glutamic pyruvic transaminasis, creatine kinase and latic desydrogenase, just to detect concomitant signs ofan inflammatory muscles diseases; 4) To demonstrate acute or chronic signs denervation or miophatic muscles processes using electromyografic procedure. In this group we found prevalence of female with 90%. The average age was 30 to 60years in 80% of the cases. A Iso 80% were white females with fibromyalgia at leastfor 90 months. This happenede with 78% of the cases. These data seems to be similar to the literature. All general symptoms, like those worsened by fhysical activities, weather changes, anxiety/stress sllep changes, fatigue, chronic headache, irritable bowel syndrome, subjective swelling and stifness at the extremeties, showed us a hight frequency such as that of literature, except for symptons concerning irritable bowel syndrome found in 4% of the patients. The average of aching points (9.4 +/- 3. l) as well as the frequency of envolvement in several anatomic parts, were according with the literature, with high incidence to the lumbar, cervical and shoulders regions. The laboratorial test were normal without any signs suggestive of inflamatory muscles or auto immune diseases. Electromyografhic did not demonstrate electric alterations such as denervation and myopathic or myositic alteration, but in 56.4% of the patients it was observed difficulties to muscle relaxation, complicating the interpretation of electromyography results, which Will be a subject for further studies.
