简要总结
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.
详细描述
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.

Visual presentation of arithmetic equations (Addition, Subtraction, Multiplication) projected on a screen. Participants must calculate and verbally report the answer within a 10-second window per equation.
干预措施: Mental Arithmetic (Behavioral)
Passive Viewing
Passive viewing of a black screen with no cognitive demand.
干预措施: Passive Viewing (Behavioral)
结局指标
主要结局
Gait Speed (10mWT)
时间窗: Immediately following the 30-second cognitive stimulus.
Assessed using the Ten-Meter Walk Test (10mWT). Participants walk 14 meters; time is recorded for the middle 10 meters to determine steady-state gait speed.
Dynamic Balance (TUG)
时间窗: Immediately following the 30-second cognitive stimulus.
Assessed using the Timed Up and Go (TUG) test. Time taken to stand from a chair, walk 3 meters, turn, walk back, and sit down.
