The Effects of Dual-Task Exergaming versus Conventional Balance Training on Motor and Cognitive Function in Chronic Stroke: A Protocol for a Single-Blind Randomized Controlled Trial

Stroke is a principal cause of global death and disability, creating a substantial economic and societal burden 1, 2. In the United States alone, around 795, 000 strokes happen each year, with costs estimated at 56. 2 billion for 2019-2020 3. Survivors frequently contend with persistent motor dysfunction like hemiparesis, balance problems that increase fall risk, and cognitive impairments affecting memory, attention, and executive function, all of which disrupt daily life 456. While restoring balance and gait is essential for regaining independence, traditional rehabilitation often addresses physical and cognitive deficits separately 7, 8. This approach is suboptimal, as real-world activities demand the simultaneous use of both motor and cognitive skills-a capability often diminished in stroke survivors 9. The performance decline observed when two tasks are performed concurrently, known as dual-task interference, is more pronounced in individuals post-stroke compared to healthy controls 10. The need for more comprehensive interventions has
