Dual-Task Exercises for Dynamic Balance, Motor Function, Functional Mobility, and Dual-Tasking in Individuals With Parkinson’s Disease: A Meta-Analysis With Meta-Regression

Vollständiger Abstract

Worum geht es in dieser Arbeit?

To evaluate the (1) effectiveness of dual-task (DT) exercise in improving dynamic balance, motor function, functional mobility, dual-tasking, and falls, and (2) influence of DT intervention parameters on treatment effects in individuals with Parkinson’s disease (PD). A comprehensive literature search was conducted across 12 electronic databases to identify relevant published articles from inception to September 2025. Risk of bias, methodological rigour, and evidence quality were evaluated using the RoB-2, PEDro, and GRADE tools, respectively. Dynamic balance, motor function, functional mobility, dual-tasking, and falls were assessed. Meta-analysis was performed to estimate intervention effects, and meta-regression evaluated how parameters of DT intervention affected treatment effects. The meta-analysis included 25 studies involving 1,162 individuals with PD. The mean PEDro score was 6.5, RoB-2 indicated a low risk of bias in 11 studies (45%), and GRADE indicated low to high evidence quality. Meta-analysis revealed significant improvements in dynamic balance (mean difference [MD]=4.45, 95% confidence interval [CI]=2.06 to 6.84; p
