Primary

MeasureTime frame
Improvement in pain, assessed using the following instruments: visual analogue pain scale, McGill Pain Questionnaire and pressure algometry. It is expected that the group treated with low power laser presents significant reduction of pain intensity scale analogic visual and increased pain threshold force to the pressure in algometry and the lower frequency in the selection of pain descriptors in categories affective and sensory and psycho-emotional component in the responses obtained in the McGill Pain questionnaire

Secondary

MeasureTime frame
Improving quality of life and sleep, as assessed through the following instruments: test generic Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the specific Fibromyalgia Impact Questionnaire (FIQ), polysomnography, and questionnaire Berlin Epworth sleepiness scale.It is expected that the group treated with low-power laser shows improvement in overall quality of life as assessed by testing generic Medical Outcomes Study 36-Item and Short-Form Health Survey (SF-36) mainly in the items, which include scales related to functional capacity, physical, bodily pain, general health and vitality. In the questionnaire Fibromyalgia Impact Questionnaire (FIQ), is expected to improve the quality of life issues related to the functional capacity, employment status, psychological distress and physical symptoms.
