rTMS plus dual-task gait training to improve walking and thinking after stroke
Effects of Dorsolateral Prefrontal Cortex rTMS Primed Dual-Task Gait Training on Walking and Cognitive Outcomes After Stroke: A Randomized Sham-Controlled Trial
NA · The Hong Kong Polytechnic University · NCT07356687
This trial will test whether brief rTMS to the dorsolateral prefrontal cortex given before dual-task walking training helps people with chronic stroke walk and think better when doing both at once.

What this trial studies
This randomized, double-blind, placebo-controlled trial will allocate community-dwelling adults with chronic unilateral stroke to receive either active or sham rTMS to the dorsolateral prefrontal cortex immediately before the same standardized dual-task gait training program. Participants complete 12 supervised sessions over 3 weeks, with assessments at baseline, immediately after training, and at a 4-week follow-up. Co-primary outcomes are dual-task cost for gait speed and cognitive-task performance during walking, while secondary outcomes include balance, community participation, mood, sleep, and fall incidence. The protocol also measures prefrontal cortex activity during single- and dual-task walking to explore neural mechanisms.
Who should consider this trial
Good fit: Ideal candidates are community-dwelling adults aged 50 or older who are at least 6 months post unilateral ischemic or hemorrhagic stroke, can walk independently for at least one minute (assistive device allowed), have mRS 1–3 and MoCA ≥22, and can follow commands.
Not a fit: Patients with cerebellar or brainstem strokes, severe aphasia, uncontrolled seizures, pacemakers or other TMS contraindications, inability to tolerate exercise, or those receiving concurrent formal rehabilitation elsewhere are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, combining rTMS with dual-task gait training could improve walking speed and cognitive performance during everyday multitasking, potentially reducing fall risk and increasing independence.
How similar studies have performed: Small prior studies suggest rTMS can modulate prefrontal function and improve cognitive or motor outcomes after stroke, but directly combining DLPFC rTMS with dual-task gait training is a novel approach with limited direct evidence.
