Non-invasive brain stimulation for enhancing dual-task performance in individuals with chronic poststroke hemiparesis: protocol for systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Dual-tasking is commonly used to assess functional capacity in neurologically intact and poststroke populations. Stroke survivors often experience significant dual-task deficits due to cognitive-motor interference and neurological impairments that limit mobility and daily participation. Emerging evidence suggests non-invasive brain stimulation (NIBS) may enhance neuroplasticity and improve dual-task performance; however, findings remain limited and inconsistent. This systematic review aims to evaluate the effects of NIBS as a central nervous system priming technique on dual-task performance in individuals poststroke. Methods and analysis: This protocol follows Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines and is registered with PROSPERO (CRD420250644455). A comprehensive search will be conducted in PubMed (MEDLINE), Embase, Web of Science and Scopus using keywords related to stroke, dual-tasking and NIBS. Reference lists of included studies will also be manually screened. Eligible studies must be randomised controlled trials or crossover designs involving adults poststroke that use NIBS while explicitly evaluating dual-task performance. Two independent reviewers will assess study quality using the Cochrane Risk of Bias tool, with disagreements resolved by a third reviewer. Meta-analysis will be conducted when feasible; otherwise, a narrative synthesis will be provided.This review will clarify current evidence supporting NIBS for improving dual-task motor-cognitive outcomes in stroke rehabilitation and may guide clinical decision-making and future neurorehabilitation research. Ethics and dissemination: Ethical approval is not required because no human participants are involved. Findings will be disseminated through peer-reviewed publications and conference presentations. PROSPERO registration number: CRD420250644455.
