What this Trial Is About
Stroke often impairs lower limb control, resulting in gait abnormalities and difficulties in dual-task performance, such as walking while engaging in cognitive activities. This study examines the effects of a single session of transcranial direct current stimulation (tDCS) targeting the left dorsolateral prefrontal cortex (DLPFC) on dual-task walking performance in individuals with chronic stroke. Using a cross-over design, participants will undergo two sessions (active or sham tDCS, 7 ± 2 days apart) of stimulation at 2 mA for 30 minutes. Walking performance will be measured using single and dual-task conditions combining motor (e.g., 20 m walk) and cognitive tasks (e.g., word association, random number recall). Primary outcomes include walking speed (m/s), stride length (m), and dual-task cost (DTC) for mobility and cognitive speed. The study aims to evaluate tDCS as a potential tool to reduce DTC, improve dual-task performance, and improve daily function and quality of life in stroke survivors. Results may guide the development of tailored dual-task interventions in stroke rehabilitation.
