About this trial
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.

Treatments tested in this trial
Mental Arithmetic
BehavioralVisual 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.
Passive Viewing
BehavioralPassive viewing of a black screen with no cognitive demand.
Treatment groups
17 Participants
are divided into 2 treatment groupsGroup A: Intervention: Behavioral: Mental ArithmeticExperimental treatment 1 intervention
Group B: Passive ViewingPlacebo comparator 1 intervention
Trial outcomes
Primary outcomes
1
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.
Time frame
Immediately following the 30-second cognitive stimulus.2
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.
Time frame
Immediately following the 30-second cognitive stimulus.Sponsors and contacts
