Objectives:
Stroke predominantly affects older adults and is accompanied by age-related declines in balance and mobility. Given the inter-individual variability in post-stroke functional capacity, identifying the most effective dual-task training modalities for specific patient profiles is essential for precision-based stroke rehabilitation. This systematic review and meta-analysis aimed to investigate the differential effectiveness of motor dual-task training (MDT) and cognitive dual-task training (CDT) on gait performance, balance control, and motor function while exploring other moderating factors.
Methods:
The study followed the PRISMA guidelines. A comprehensive search of six English databases (Web of Science, PubMed, Medline, Embase, Cochrane Library, CINAHL) and one Chinese database (CNKI) was conducted from November 2023 to June 2025. Randomized controlled trials involving adult stroke survivors were included. Outcomes included gait, balance, and lower-extremity motor function. Random-effects meta-analysis, subgroup analyses, and meta-regression were performed to evaluate modality-specific effects and moderating factors.
Results:
Twenty-one RCTs (n = 786) were included. Dual-task training demonstrated moderate improvements in both temporal (SMD = 0.50, p = 0.03) and spatial (SMD = 0.5, p = 0.04) gait performance and balance control (SMD = 0.71, p = 0.02), but not motor function. MDT demonstrated superior effects on gait speed and stride length (SMD = 1.15, p = 0.01; SMD = 0.89, p < 0.01), whereas CDT showed greater benefits for balance (SMD = 0.59, p < 0.01). Greater balance improvements were observed in individuals at high fall risk, and subacute patients showed enhanced responsiveness.
Conclusions:
These findings provide guidance for tailoring dual-task modality and timing to individual patient profiles, though high heterogeneity and the lack of direct comparisons between MDT and CDT limit definitive conclusions.
