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.
Article in Annals of rehabilitation medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
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<0.001), motor function (MD=-2.00, 95% CI=-3.32 to -0.67; p<0.001), functional mobility (MD=-1.64, 95% CI=-2.01 to -1.26; p<0.001), and dual-tasking (MD=-3.39, 95% CI=-4.67 to -2.11; p<0.001). Meta-regression revealed that dynamic balance improved with moderately challenging and moderate-intensity DT exercises, practised for 2 hours weekly with ≥90% session adherence. Subgroup meta-analyses revealed that practising for more than 4 weeks significantly improved dynamic balance and functional mobility. Compared with traditional single-task exercises, motor-cognitive DT exercises improved dynamic balance, functional mobility, motor function, and dual-tasking. Further studies examining the effects of DT exercises on falls among individuals with PD are warranted.
