Abstract：
The aging population warrants the increase of mild cognitive impairment (MCI) prevalence, a condition that could progress to dementia. Efforts have been made to improve the MCI and prevent its progression, including the introduction of Tai Chi, a Chinese traditional exercise. The aim of this systematic review and meta-analysis was to evaluate the efficacy of Tai Chi in attenuating MCI among the elderly population. Records investigating the effect of Tai Chi exercise intervention on cognitive function among elderly patients were searched systematically from PubMed, ScienceDirect, Google Scholar, and Europe PMC as of April 13, 2023. The risk of bias (RoB 2.0) quality assessment was employed in the quality appraisal of the studies included. Review Manager 5.4.1 was used for data extraction and meta-analysis, where the standard mean difference (SMD) and 95% confidence interval (95%CI) were computed. Eight randomized control trials with a total of 1379 participants were included in this meta-analysis. Six trials assessed Montreal Cognitive Assessment scores, where its pooled analysis suggested that Tai Chi was as effective as conventional exercise (SMD=0.15, 95%CI: -0.11 to 0.40, p=0.26). However, pooled analysis of the Mini-Mental Status Examination suggested that Tai Chi intervention more effectively improved cognitive function and reduced the rate of cognitive impairment in elderly patients (SMD=0.36, 95%CI: 0.18 to 0.54, p<0.01) as compared to the control group. This systematic review and meta-analysis suggest that, in some extent, Tai Chi is efficacious in improving cognitive function and slowing down the rate of cognitive impairment among elderly patients.
摘要：
人口老龄化导致轻度认知障碍（MCI）患病率增加，可能发展为痴呆症的情况。已经努力改善MCI并防止其进展，包括太极拳的引进,中国传统的锻炼。本系统评价和荟萃分析的目的是评估太极拳在减轻老年人群MCI中的功效。从PubMed系统检索太极拳运动干预对老年患者认知功能影响的记录,ScienceDirect,谷歌学者，和截至2023年4月13日的欧洲PMC。偏倚风险（RoB2.0）质量评估用于纳入研究的质量评估。ReviewManager5.4.1用于数据提取和荟萃分析，计算标准平均差(SMD)和95%置信区间(95CI)。该荟萃分析包括8项随机对照试验，共有1379名参与者。六项试验评估了蒙特利尔认知评估得分，其汇总分析表明太极拳与常规运动一样有效（SMD=0.15，95CI：-0.11至0.40，p=0.26）。然而,对简易精神状态检查的汇总分析表明，与对照组相比，太极拳干预更有效地改善了老年患者的认知功能并降低了认知障碍的发生率（SMD=0.36，95CI：0.18至0.54，p<0.01）。这项系统评价和荟萃分析表明，在某种程度上,太极拳可有效改善老年患者的认知功能，减缓认知障碍的发生率。
