Each patient underwent two counterbalanced interventions of stimulation (ctDCS and sham) separated by a 1-week rest period. Each intervention consisted of five consecutive days of stimulation coupled with customary rehabilitative word-retrieval training (see Methods). A standardized, validated Korean version of the BNT (Kim & Na, 1997), composed of 60 culturally customized pictures was administered before and after the series of stimulation sessions as an outcome measure.
