ABSTRACT
ntroducción: La fibromialgia (FM) es una patología crónica caracterizada por la presenciade dolor musculoesquelético generalizado que se asocia a trastornos psicológicos que afectana la calidad de vida. En los últimos anos, la estimulación transcraneal con corriente directa(tDCS) y la estimulación magnética transcraneal (TMS) se han estudiado para el abordaje deldolor crónico. El objetivo de esta revisión es determinar los efectos de la tDCS y la TMS en lossíntomas característicos de los pacientes con FM.Desarrollo: Se realizó una revisión sistemática acorde a los criterios PRISMA. Se realizaronbúsquedas en las bases de datos Medline, Scopus, PEDro y Cochrane Library. Se seleccionaronensayos clínicos aleatorizados que analizaran los efectos de estas intervenciones en el dolor, elumbral de dolor a la presión, la fatiga, la ansiedad y depresión, el catastrofismo y la calidad devida en pacientes con FM. Se incluyeron 14 estudios.Conclusiones: La aplicación de tDCS en el córtex motor es la única intervención que ha mos-trado disminuir el dolor a corto y medio plazo en pacientes con FM. La aplicación de ambasintervenciones ha mostrado mejoras en el umbral de dolor a la presión, el catastrofismo y lacalidad de vida cuando se aplica en el córtex motor, y de la fatiga cuando se aplica en la cortezadorsolateral prefrontal. Los efectos de estas intervenciones en la ansiedad y depresión no sonconcluyentes.(AU)
Introduction: Fibromyalgia syndrome (FM) is a chronic pathology characterized by widespreadpain commonly associated with psychological distress affecting quality of life. In recent years,transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) havebeen investigated to treat chronic pain. The aim of the current review is to determine theeffects of tDCS and TMS on the main symptoms of patients with FM.Development: A systematic review based on PRISMA guidelines was carried out. The searchstrategy was performed in Medline, Scopus, PEDro and Cochrane Library. Randomized controlledtrials based on the effects of tDCS and TMS on pain, pressure pain threshold, fatigue, anxietyand depression, catastrophizing and quality of life in patients with FM were analysed. Fourteenstudies were included.Conclusions: The application of tDCS to the motor cortex is the only intervention shown todecrease pain in the short and medium-term in patients with FM. The application of bothinterventions showed improvements in pressure pain threshold, catastrophizing and quality oflife when applied to the motor cortex, and in fatigue when applied to the dorsolateral prefrontalcortex. The effects of these interventions on anxiety and depression are unclear.(AU)

The search strategy was performed in MEDLINE, SCOPUS, PEDro and Cochrane Library. Randomised controlled trials based on the effects of tDCS and TMS on pain, pressure pain threshold (PPT), fatigue, anxiety and depression, catastrophising and quality of life in patients with FM were analysed. Fourteen studies were included. CONCLUSIONS: The application of tDCS to the motor cortex is the only intervention shown to decrease pain in the short and medium-term in patients with FM. The application of both interventions showed improvements in PPT, catastrophising and quality of life when applied to the motor cortex, and in fatigue when applied to the dorsolateral prefrontal cortex.
