Targeted Transcranial Direct Current Stimulation to Enhance Speech-Language Treatment Outcome in Persons With Chronic Post-Stroke Aphasia
62 patients who are one year post stroke and have Aphasia as a result of that stroke will be recruited. Participants will have 4 assessment sessions and 15 treatment sessions. The TDCS will be to right Inferior Frontal Gyrus (IFG) (25 active, 25 sham) for 15 days. A combined semantic feature analysis/phonological components analysis treatment will be paired with the stimulation. Two assessment sessions will be pretreatment, 1 session immediately post-treatment, and 1 session at 3 months follow-up.
