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.
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.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Short tests of memory and thinking, each scored out of 30. Lower scores suggest more difficulty; criteria give a range, either to include people with memory problems or to leave them out.

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 of a black screen with no cognitive demand.
Behavioral: Passive Viewing

Passive viewing of a black screen with no cognitive demand.
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.
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.
Plan to share: Yes — Individual participant data (IPD) that underlie the results reported in this article (after de-identification) will be shared. This includes the data used to generate the tables and figures.
Supporting information: Study protocol, Statistical analysis plan, Informed consent form
Time frame: Data will be available beginning 6 months and ending 5 years following article publication.
Access criteria: Data will be shared with researchers who provide a methodologically sound proposal to the corresponding author. Proposals should be directed to ahmadrifaisarraj@ul.edu.lb. To gain access, data requestors will need to sign a data access agreement.
Start is estimated for Sep 2026; primary completion for Dec 2026, 3 months later.
Of 3,108 non-industry interventional studies with no phase under Stroke, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 46. This study's planned 3 months is below that.
Counting every sponsor, half of 3,252 studies reached it within 23 months; a quarter within 10 and three quarters within 46.
