New assessment approach could personalize dual-task walking rehabilitation after stroke
Multitasking while walking—be it mentally drafting a grocery list or replying to a text message on a phone—is simply second nature to many. For stroke survivors with weakened mobility and cognitive abilities, however, this common practice of dual-task walking can present a formidable challenge.
A new study conducted by researchers at The Hong Kong Polytechnic University (PolyU) could revolutionize the way stroke rehabilitation is approached, particularly for dual-task walking. This assessment method aims to personalize rehabilitation by considering the interaction of cognitive task type and complexity on dual-task interference (DTI), which can significantly impact both physical and mental performance.
Led by Professor Marco Pang, the study revealed that patients with chronic stroke often experience DTI during dual-task walking, impacting their walking distance and cognitive function, such as recall tasks. The research also demonstrated that the severity of DTI varies depending on the type of cognitive task. Tasks requiring internal processing, like serial subtraction, caused greater walking impairment compared to externally driven tasks.
Professor Pang emphasized the need for individualized assessments to better understand these challenges faced by stroke survivors. He stated that dual-task exercise training can reduce DTI and fall risk, but a comprehensive Dual-Task Effect (DTE) profile is essential for effective rehabilitation.
Assistant Professor Charlotte Tsang added that a one-size-fits-all approach to rehabilitation is inadequate, as strokes affect different brain regions responsible for cognitive and physical functions. The study highlights the necessity of incorporating realistic dual-task scenarios into rehabilitation programs to improve outcomes for stroke patients.
