Dual-task training has been a popular intervention for individuals with balance impairments. However, the effects of dual-task training on chronic ankle instability (CAI) have not been comprehensively analyzed and reliable clinical evidence is scarce. The purpose of this systematic review and meta-analysis is to evaluate the effectiveness of dual-task training on postural stability and functional ability in individuals with CAI.
PubMed, Web of Science, EBSCO, Cochrane Library, Physiotherapy Evidence Database (PEDro), and China National Knowledge Infrastructure (CNKI) were researched from inception to November 2022. This study was conducted by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two reviewers assessed the studies for inclusion and extracted data. The Cochrane Risk of Bias list was used to assess the risk of bias in included studies. Mean differences (MD) with a 95% confidence interval (CI) were calculated with the RevMan 5.3 software.
A total of 7 randomized controlled trials with 192 CAI met the inclusion criteria. The meta-analysis results showed that compared with the control group, dual-task training significantly improved the Y-balance test (MD = 1.60, 95% CI: -0.00 to 3.21, P = 0.050) and reduced COP-area (MD = - 0.94, 95% CI: -1.62 to - 0.26, P = 0.007) in individuals with CAI. However, there is no significant difference between dual-task training and the control group on COP-velocity (MD = - 0.26, 95% CI: -0.70 to 0.17, P = 0.240), hop test (MD = - 0.20, 95% CI: -0.66 to 0.26, P = 0.386) and BESS (MD = - 1.24, 95% CI: -2.95 to 0.48, P = 0.157) in individuals with CAI.
This meta-analysis showed that dual-task training may be effective in improving static and dynamic postural stability. However, more high-quality randomized controlled trials are needed to verify the short and long-term effectiveness of dual-task training on CAI.
双任务训练已成为一种治疗平衡障碍患者的常用方法。然而，关于双任务训练对慢性踝关节不稳定（CAI）的影响尚未进行全面分析，可靠的临床证据也很少。本系统评价和荟萃分析的目的是评估双任务训练对 CAI 患者姿势稳定性和功能能力的有效性。
从建库至 2022 年 11 月，检索了 PubMed、Web of Science、EBSCO、Cochrane 图书馆、物理治疗证据数据库（PEDro）和中国知网（CNKI）。本研究按照系统评价和荟萃分析的首选报告项目（PRISMA）指南进行。两名审查员评估纳入研究的纳入和提取数据。使用 Cochrane 偏倚风险清单评估纳入研究的偏倚风险。使用 RevMan 5.3 软件计算具有 95%置信区间（CI）的均数差（MD）。
共有 7 项符合纳入标准的随机对照试验，涉及 192 名 CAI 患者。荟萃分析结果显示，与对照组相比，双任务训练显著改善了 Y 平衡测试（MD=1.60，95%CI：0.00 至 3.21，P=0.050）和减少了 CAI 患者的姿势控制测试（COP）面积（MD=-0.94，95%CI：-1.62 至 -0.26，P=0.007）。然而，双任务训练与对照组在 CAI 患者的 COP 速度（MD=-0.26，95%CI：-0.70 至 0.17，P=0.240）、跳测试（MD=-0.20，95%CI：-0.66 至 0.26，P=0.386）和 BESS 测试（MD=-1.24，95%CI：-2.95 至 0.48，P=0.157）方面无显著差异。
本荟萃分析表明，双任务训练可能有助于改善静态和动态姿势稳定性。然而，需要更多高质量的随机对照试验来验证双任务训练对 CAI 的短期和长期效果。
