Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study investigates the effect of cognitive priming through mental arithmetic on functional mobility in post-stroke patients. It hypothesizes that performing mental calculations (addition, subtraction, multiplication) prior to movement stimulates frontoparietal networks, thereby improving gait speed and dynamic balance compared to a passive control condition.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Stroke often results in impaired sensorimotor integration and executive dysfunction, leading to gait and balance deficits. Emerging evidence suggests a link between numerical cognition and motor control networks. This randomized controlled trial compares an experimental group (performing 30-second mental arithmetic tasks) against a control group (passive visual exposure). Functional mobility is assessed immediately following the cognitive stimulus using the Ten-Meter Walk Test (10mWT) and the Timed Up and Go (TUG) test to evaluate the immediate "priming" effects of cognitive load on motor performance.
