Effects of Cognitive Motor Dual-Task Training on Stroke Patients: A RCT-based Meta-Analysis.

Based on a randomized controlled trial (RCT), this meta-analysis aimed to comprehensively analyze the effects of cognitive motor dual-task training (CMDT) on stroke patients. The electronic databases PubMed, Embase, and the Cochrane Library were searched for papers on the influence of CMDT on stroke patients. Weighted mean difference (WMD) and 95% confidence interval (95% CI) were used as effect sizes. Cochran's Q and I-2 tests were performed for heterogeneity. Thirteen articles involving 326 patients were included in the study. The meta-analysis showed that CMDT significantly improved the walking balance of patients with stroke (P = 0.01). In addition, CMDT significantly improved the gait ability of patients with stroke (P < 0.0001). Furthermore, CMDT had a significant effect on the improvement of upper limb ability in patients with stroke (P < 0.00001). CMDT could significantly improve balance ability, gait, and upper limb function in patients with chronic stroke, which is worthy of clinical promotion. (C) 2021 Elsevier Ltd. All rights reserved.
