Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This preliminary study aimed to examine the effect of excitatory (anodal) stimulation of right inferior frontal gyrus (IFG) on naming abilities of chronic people with aphasia (PWA) to examine the compensatory versus interference role of RH in language recovery, and to confirm the application of tDCS does not induce adverse effects on other cognitive and language functions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
anodal tDCS
20 minutes of one mA anodal High-Definition tDCS (HD-tDCS) over right IFG combined with 40 minutes of naming therapy for five consecutive days in week 1
tDCS stimulation
The study examines the effect of excitatory stimulation of right inferior frontal gyrus (IFG) on naming abilities of people with aphasia (PWA) as compared to sham stimulation to examine the compensatory versus interference role of right hemisphere in language recovery after stroke.
sham tDCS
20-minutes sham HD-tDCS with 40-minutes therapy of naming therapy for five consecutive days in week 1
tDCS stimulation
The study examines the effect of excitatory stimulation of right inferior frontal gyrus (IFG) on naming abilities of people with aphasia (PWA) as compared to sham stimulation to examine the compensatory versus interference role of right hemisphere in language recovery after stroke.
