Background: Among the diseases that encompass chronic pain is fibromyalgia (FM), a syndrome characterized by changes in the functional, chemical and structural networks of the brain. Objectives: To analyze the effects of anodic Transcranial Direct Current Stimulation (tDCS) on the Primary Motor Cortex (M1) for 26 minutes for 10 sessions in the treatment of pain in patients with FM. Design and setting: Randomized double-blind clinical trial to be carried out at the Municipal Physiotherapy Clinic of Fátima do Sul - MS, Brazil. Methods: This is a Research protocol that is in progress. Forty women aged between 18 and 60 years with a medical diagnosis of FM will be selected. Participants will be randomly assigned to two groups (active tDCS and tDCS sham). There will be 10 consecutive sessions. The anode will be positioned at M1 and the cathode in the right sub-orbital region. The intensity will be 2mA applied for 13 minutes, a break of 20 minutes followed by another 13 minutes of stimulation. In the tDCS sham group, the device stays on for 30 seconds and turns off automatically. Participants will be evaluated at the beginning, after 10 sessions and after 30 and 90 days with the visual analogue scale, inventory of attitudes towards pain (primary outcome). Results: this will be the first clinical trial to use this prochotole. Potential limitations include patient compliance. Conclusions: we hope to demonstrate the effects of tDCS on FM and direct further studies.
