Efeito da eletroestimulação transcraniana por corrente contínua (ETCC) associado ao exercício funcional na dor e desempenho muscular de mulheres com fibromialgia

Abstract

Introduction: Fibromyalgia (FM) is defined as a chronic painful syndrome of unknown origin and noninflammatory and mainly affects the musculoskeletal system. Non-pharmacological training is done through physical exercise, which is an important alternative, since these individuals have a significant reduction in muscle performance. The hypothesis of the study is that transcranial stimulation can generate additional effects to functional physical exercise, which in previous studies has proven to be an effective technique for pain improvement and muscle strength gain. Objective: To evaluate pain and functional performance before and after associated exercise therapy and tDCS in women with fibromyalgia within one month. Materials and methods: Women aged 30 to 70 years with a diagnosis of FM participated in the study, being divided into active group, where functional exercise was performed + active TDCS and placebo, where functional exercise was performed + placebo tDCS within 1 month. For pain evaluation, the visual analog scale (VAS) and the pressure algometer were used. In order to evaluate physical performance, the use of the isokinetic dynamometer (Biodex Multi-Joint System 3, Biodex Biomecal System Inc, New York, USA) was found. was submitted to functional exercise associated with placebo tDCS for the variables pain (p = 0.218) and muscle performance for flexor strength (P = 0.973) and extensor strength (P = 0.093). Conclusion: There was no statistical difference for improvement in pain and muscle performance in the application of a functional exercise program associated with tDCS in women with fibromyalgia within 1 month.
