Objective: Evaluate the efficacy of laser phototherapy treatment on myofascial trigger point in the trapezius muscle in fibromyalgia patients. Methods: We evaluated 25 subjects diagnoses of myofascial pain and fibromyalgia according to the criteria of the with American College of Rheumatology (ACR) 1990, which were divided into: Group Laser (n = 8), group laser + drug (n = 10) and group drug (n = 7) receiving lasertherapy 2 times per week for 5 weeks. The variables measured were: 1) intensity of pain by visual analogue scale (VAS) in the times basal, 5th, 10th session, 2) threshold pressure pain (LDP) through a pressure algometer in the basal, 5th, 10th session, 3) evaluation of the pain through the general Questionnaire Rolland-Morris (QIRM) in the times basal end and, 4) assessment of fear of moving the affected limb through the Tampa Scale for kinesiophobia (ETC) at the times baseline and end; 5) evaluation of the impact of fibromyalgia on quality of life (QIF) in the times basal and final. All data were analyzed by analysis of variance (ANOVA), two-way repeated measures followed by the Tukey post-test, when appropriate. For cases in which the interaction between factors (treatment and time) was significant, we conducted ANOVA for repeated measures oneway for each treatment group. All tests were two-tailed and performed at a significance level of 5%. Results: There was a decrease in pain intensity and increase the LDP in the trapezius muscle in the 5th and 10th sessions compared to baseline for the groups that LLLT was used. No significant interaction was found between the scores of the variables QIRM, ETC and QIF between groups, except for the sub-scale of the QIF, stiffness and anxiety that showed significant differences between groups. Conclusion: The laser phototherapy caused a decline in the intensity of local pain and an increase in the LDP trapezius muscle. Furthermore, improved symptoms of anxiety and rigidity. We suggest an indication of the laser as adjuvant in the treatment of patients with myofascial pain associated with fibromyalgia.
