Clinical Trial Summary

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.


Clinical Trial Description

Our long-term goal is to develop safe and effective treatments for the communication problems of Aphasia due to stroke that restore patients to higher levels of functioning, decrease disability, and promote higher quality of life. While language therapy for aphasia is effective, improvements are typically slow, and gains may be small. Noninvasive brain stimulation has been suggested as a method to enhance outcomes from language therapy. This study will examine whether outcomes for language therapy with brain stimulation are different from outcomes for language therapy without brain stimulation in people with aphasia. Our central hypotheses are (1) targeted right hemisphere HDtDCS (RH-HD-tDCS) administered in combination with language treatment will result in greater changes in naming accuracy than language treatment with the sham RH-HD-tDCS (2) RH-HD-tDCS plus language treatment will result in greater increases in communication within the affected hemisphere compared to language treatment plus sham RH-HD-tDCS (3) RH-HD-tDCS plus language treatment will result in greater increases in perilesional areas working together immediately post-treatment compared to language treatment plus sham RH-HD-tDCS ;
