Condition: Stroke · tDCS · Action Observation Therapy · Sponsor: Universiti Malaysia Sabah
This study investigates the neurophysiological mechanisms underlying the combined use of transcranial direct current stimulation (tDCS) and action observation therapy (AOT) for hand motor recovery in individuals with stroke. Background: While both tDCS and AOT have shown promise individually for stroke rehabilitation, the neural mechanisms of their combined effects remain unclear. Understanding these mechanisms could optimise rehabilitation protocols and improve functional outcomes. Intervention: Participants will receive 10 sessions of anodal tDCS over the ipsilesional motor cortex combined with AOT over two weeks in a clinical setting, followed by 8 weeks of home-based AOT practice. Control groups will receive tDCS alone or AOT alone. Neurophysiological changes will be assessed using motor evoked potentials (MEPs) to evaluate corticospinal excitability. Clinical hand function will be assessed using standardised outcome measures. Measurements: Assessments will be conducted at baseline, during intervention (week 2), and after the home practice phase (week 10) to evaluate neuroplastic changes. Significance: This study will provide mechanistic insights into how neuromodulation and observational learning interact to promote motor recovery, informing evidence-based rehabilitation strategies for stroke survivors in Malaysia and globally. Study Design: Randomised controlled trial with three parallel arms, recruiting 60 participants with chronic stroke from Sabah, Malaysia.
