Montage of HTDCS in Psycho-cognitive Functions in FM

Not Applicable
Conditions
Fibromyalgia
Interventions
Device: Transcranial Direct Current Stimulation (tDCS)
Registration Number
NCT04890964
Lead Sponsor
Hospital de Clinicas de Porto Alegre
Brief Summary

This study aims to map the impact of anodic transcranial direct current stimulation (tDCS) for prolonged home use applied to the primary motor cortex and the left dorsolateral prefrontal córtex (DLPFC), compared to the respective treatments simulated in fibromyalgia.

Detailed Description

This study aims to map the impact of anodic tDCS for prolonged home use applied to the primary motor cortex and the left dorsolateral prefrontal córtex (DLPFC), compared to the respective treatments simulated in fibromyalgia, targeting the outcomes of the following axes: (1) pain intensity and functional capacity; (2) psycho cognitive functions; (3) neurophysiological markers; (4) biological rhythm markers; (5) to map the potential of neurophysiological markers, biological rhythm and history of trauma in childhood and adolescence in functional capacity, depressive symptoms and working memory tests.
