About this trial
This study aims to evaluate the effects of tDCS combined with cognitive-motor training on dual-task interference during walking and foot pedaling, alongside corresponding alterations in brain activity assessed via fNIRS. Additionally, an fMRI component was conducted as a nested sub-study for deep mechanistic exploration.

having a Montreal Cognitive Assessment score ≥ 22,
Disqualifiers
neurological disorders, gait-precluding pain or comorbidity,
receiving any formal rehabilitation training,
