Title: Transcranial Direct Current Stimulation in Rehabilitation of Chronic Stroke Patients: Multicenter Clinical Trial
Brief Summary: In this study, the investigators wondered whether bihemispheric transcranial direct current stimulation (tDCS) would be capable to potentialize the effects of physical therapy on upper limb rehabilitation of chronic stroke patients. Moreover, the study aims to investigate the pattern of physiological variables involved in the recovery of these patients. For this purpose, patients included will be submitted to 10 sessions with active or sham bihemispheric tDCS associated with intensive and individual physical therapy session.
