To evaluate the hypothesis: the effects of repetitive transcranial magnetic (rTMS) stimulation and/or peripheral stimulation (neurofunctional electrical acupuncture) treatments are more effective in pain relief than placebo-sham in patients with myofascial chronic pain.

This project is a multidisciplinary study, with available technology, which aims are to provide more data to consolidate the techniques of central and peripheral neuromodulation in the treatment of myofascial pain with a component in the craniofacial complex . This is a randomized, double-dummy, factorial, blind, parallel, placebo - sham controlled clinical trial. The issues investigated in this study include important public health problem because chronic musculoskeletal pain affects 30 % of the world population , according to WHO. Around 75-80 % of people seeking health care for pain and that 40% of adults suffer from some type of chronic pain. According to the severity of the problem , the International Association for the Study of Pain has defined the year 2010 as the International Year Against Musculoskeletal Pain, facing the increasing prevalence and the limited impact of the classical therapeutic interventions ( \ 30 % ). Possibly, part of this poor response is due to the limitation of pathophysiological knowledge, few resources in diagnostic methods and the consequent implementation of measures that do not reach the main routes of this disease process. It is important to mention that epidemiological studies have greatly contributed to improve the understanding of the process of these musculoskeletal diseases, but increase few knowledge about the understanding of the pathophysiology, diagnostic and therapeutic developments. It is important to highlight that evidence has shown strong association of musculoskeletal pathologies conditions and chronic stress. This relationship is cascading and permeated by manifestations suggest that the neuro-immune-endocrine axis, such as poor sleep quality, anxiety symptoms, depressive symptoms, increased susceptibility to infections and manifestations of neuro-vegetative dysfunctions. Thus, this project will examine whether the hypothesis that the application of central and peripheral neuromodulatory therapies can have a positive impact on possible systems implicated in the pathophysiological course of musculoskeletal disorders in the craniofacial complex, and evaluate clinical outcomes characterizing the process of rehabilitation of these patients.
