NCT07327814

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Gait Speed (10mWT)

    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.

    Immediately following the 30-second cognitive stimulus.

  • Dynamic Balance (TUG)

    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.

    Immediately following the 30-second cognitive stimulus.

Study Arms (2)

Intervention: Behavioral: Mental Arithmetic

EXPERIMENTAL

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.

Behavioral: Mental Arithmetic

Passive Viewing

PLACEBO COMPARATOR

Passive viewing of a black screen with no cognitive demand.
