Background: Fibromyalgia (FM) affects the population’s physical and mental health and is characterized by changes in brain activity and pain reporting. Objectives: To systematize and discuss the effects of tDCS on pain improvement in patients with FM as well as the “state of the art”. Design and setting: Systematic review with bibliometric. Methods: Articles were searched in the databases: MEDLINE / PubMed, Web of Science, Scopus and Physiotherapy Evidence Database. Randomized clinical trials, published between 1996 and 2021, that used tDCS to treat pain in patients with fibromyalgia were included. Studies that used tDCS associated with another technique (except pharmacological) were excluded. Methodological quality and risk of bias were assessed using the PEDro and Rob 2.0 scale. Software R. was used to perform bibliometrics. Results: Nine articles were included, totaling 306 participants. The main stimulated areas were the primary death cortex (M1) (6 studies) and left dorsalateral prefrontal cortex (CPFDL) (4 studies). Eight studies used the intensity of 2 mA and application for 20 minutes. Both stimulation of M1 and CPFDL showed effects on pain improvement greater than tDCS sham. As for the research institutes, Havard Medical School and the Federal University of Rio Grande do Sul lead the ranking. The author with the greatest impact was Fregni, F. (index h: 12, index g: 17, index m: 0.800, total publications 17, beginning: 2006). Conclusions: tDCS proved to be effective for the treatment of pain in FM. The production of studies is limited.
