Active tDCS
The stimulation will be administered with a pair of surface electrodes, sponge coated, soaked in saline. A battery-powered constant current stimulator will be used for this purpose (tDCS device). The stimulation is performed by placing the anodal electrode in the primary motor cortex (M1) and the cathodal one in the contralateral supraorbital area and it will use a 2 mA (milliampere) current.
Sham tDCS
The sham tDCS consists in the same montage of the active tDCS, but the device is turned off 30 seconds after stimulation starts (without letting the patient notice it). The rest of the montage is kept identical to the active one during the 20 minutes session
