Study: NCT02562222

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: anodal tDCS on M1
Description: The direct electric current will be applied by surface electrodes with 35cm² and composed of rubbers conductive electricity and surrounded by sponges soaked in saline solution. The electrodes position will be performed according the 10-20 international system of marking and the different montages will be realized by distinct applications sites.~To stimuli the primary motor cortex the active electrode will be positioned on C3 point and the reference electrode on the contralateral supraorbital region. To visual cortex stimulation, the active electrode will be positioned on the Oz point and the reference on Cz. To duo stimulation, the two electrodes will be considerate actives, stimulating the visual and motor cortex simultaneously. The sham tDCS has already been used in several studies to assess the effect active tDCS and the duration of the current is only 30 seconds.
