The aim of the present study was to systematically evaluate and quantify the effectiveness of dual-task training on gait parameters, motor symptoms and balance in individuals diagnosed with Parkinson's disease.
A systematic review of published literature was conducted until May 2020, using PubMed, EMBASE, Cochrane Library, Web of Science, EBSCO and CNKI databases.
We included randomized controlled trials (RCTs) and non-RCTs to evaluate the effects of dual-task training compared with those of non-intervention or other forms of training. The measurements included gait parameters, motor symptoms and balance parameters. Methodological quality was assessed using the PEDro scale. Outcomes were pooled by calculating between-group mean differences using fixed- or random-effects models based on study heterogeneity.
A total of 11 RCTs comprising 322 subjects were included in the present meta-analysis. Results showed that dual-task training significantly improved gait speed (standardized mean difference [SMD], -0.23; 95% confidence interval [CI], -0.38 to -0.08; = 0.002), cadence (SMD, -0.25; 95% CI, -0.48 to -0.02; = 0.03), motor symptoms (SMD, 0.56; 95% CI, 0.18 to 0.94; = 0.004) and balance (SMD, -0.44; 95% CI, -0.84 to -0.05; = 0.03). However, no significant changes were detected in step length or stride length.
Dual-task training was effective in improving gait performance, motor symptoms and balance in patients with Parkinson's disease relative to other forms of training or non-intervention.
本研究旨在系统评估和量化双重任务训练对帕金森病患者步态参数、运动症状和平衡的有效性。
截至 2020 年 5 月，使用 PubMed、EMBASE、Cochrane 图书馆、Web of Science、EBSCO 和中国知网数据库对已发表文献进行了系统评价。
我们纳入了随机对照试验（RCT）和非 RCT，以评估与非干预或其他形式的训练相比，双重任务训练的效果。测量指标包括步态参数、运动症状和平衡参数。使用 PEDro 量表评估方法学质量。根据研究异质性，采用固定或随机效应模型计算组间平均差异来汇总结果。
本荟萃分析共纳入 11 项 RCT，共 322 名受试者。结果表明，双重任务训练显著提高了步态速度（标准化均数差 [SMD]，-0.23；95%置信区间 [CI]，-0.38 至 -0.08； = 0.002）、步频（SMD，-0.25；95% CI，-0.48 至 -0.02； = 0.03）、运动症状（SMD，0.56；95% CI，0.18 至 0.94； = 0.004）和平衡（SMD，-0.44；95% CI，-0.84 至 -0.05； = 0.03）。然而，步长或跨步长度没有明显变化。
与其他形式的训练或非干预相比，双重任务训练对帕金森病患者的步态表现、运动症状和平衡具有改善作用。
