Effectiveness of TDCS Over Broca's Area in Verb Naming: a Randomized, Double-Blind, Crossover Study

Brief summary (registry, in English)

This clinical trial investigated whether transcranial direct current stimulation (tDCS) over Broca's area (F5) could improve verb naming abilities in adults with aphasia. Additionally, the study evaluated the stability of the treatment response to tDCS over time. The main questions this study sought to answer were: * Does tDCS improve verb naming abilities compared to inactive (sham) stimulation? * Are the observed effects stable over time? Participants received 10 daily sessions of tDCS over two consecutive weeks (5 days per week). The study included two treatment conditions, separated by one-month washout period: * Active tDCS: Stimulation over Broca's area at 2 mA; * Sham tDCS: Stimulation mimicking the active condition without delivering electrical current. During the treatment, participants were asked to name aloud videos of actions displayed on a computer screen. One month after each treatment condition, follow-up testing was conducted to evaluate the stability of the treatment response.
