We will invite patients recently admitted to the stroke unit of the study centers to participate in our research project. Once patients consent to our study we will randomly assign them to one of three experimental groups. For 12 days, all groups of patients will be setup with brain stimulation during their usual rehabilitation sessions. Two of those groups (treatment groups) will each receive a different type of brain stimulation (rTMS and tDCS), in the third group, patients will not receive real stimulation (placebo group). By comparing the extent of aphasia recovery between groups, we will determine the benefits attributable to brain stimulation relative to SLT alone.
