Transcranial direct current stimulation
Placebo
Transcranial direct current stimulation session: the energy of the anode (transcranial current stimulation) will have as its source a battery-powered DC generator and will be exerted by two electrodes measuring 5x7cm and attached to the head. The electrodes will be located of the primary motor cortex. The electrode with positive charge (anode) will be positioned at contralateral to the dominant limb and the negative charged electrode will be positioned in the supraorbital region ipsilateral to the dominant limb. The active current of direct transcranial stimulation will be applied with the intensity of electric current of 2mA and density of 0.057 mA/cm2 with duration of 20 minutes. During the session, patients will remain seated. Number of sessions: three times, once per day.
This group will not receive a transcranial direct current stimulation session.
