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.

Trial outcomes

Primary outcomes

1

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.

Time frame
From baseline assessment to 4-weeks post treatment

Secondary outcomes

1

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.

Time frame
From baseline assessment to 1-week post treatment
2

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.

Time frame
From baseline assessment to 24-weeks post treatment
3

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).

Time frame
From baseline assessment to 4-weeks post treatment
4

Functional Communication

To demonstrate superiority of active tDCS with speech therapy compared to sham tDCS with speech therapy in improving functional communication.

Time frame
From baseline assessment to 4-weeks post treatment
