About this trial
The purpose of this study is to help us understand if adding transcranial Direct Current Stimulation (tDCS), a non-invasive brain stimulation technique, to Speech Therapy improves language recovery in people with Broca's aphasia and is more effective than Speech Therapy alone.

Treatment groups
Trial outcomes
Primary outcomes
Naming
Change in the number of correctly named items between the average of the two pre-treatment Philadelphia Naming Test (PNT) assessments and the average of the two post-treatment PNT sessions at 4-weeks post treatment.
Secondary outcomes
Naming
To demonstrate superiority of active tDCS with speech therapy compared to sham tDCS with speech therapy in improving naming at 1-week post treatment.
Naming
To demonstrate superiority of active tDCS with speech therapy compared to sham tDCS with speech therapy in improving naming at 24-weeks post treatment.
Aphasia Severity
To demonstrate superiority of active tDCS with speech therapy compared to sham tDCS with speech therapy in reducing aphasia severity as measured by the Western Aphasia Battery-Revised Aphasia Quotient (WAB-R AQ).
Functional Communication
To demonstrate superiority of active tDCS with speech therapy compared to sham tDCS with speech therapy in improving functional communication.
