所有人在衰老过程中都会出现认知能力下降，药物只能缓解症状，而且价格昂贵。一些研究表明太极具有预防认知衰退的潜力，而另一些研究结果表明太极对认知障碍没有影响。因此，我们对认知障碍患者练习太极拳的有效性和安全性进行了系统的综述和荟萃分析。应用计算机检索PubMed、Cochrane、MEDLINE(Ovid)、Web of Science、Embase、Scope us、QicINFO(Ovid)、CKNI、万方、VIP、SinoMed、ClinicalTrails等数据库，收集有关太极治疗认知障碍患者的随机对照试验。主要结果包括认知功能的变化，次要结果包括记忆功能的变化。数据由两个独立的个体提取，Cochrane Risk of Bias工具2.0版用于纳入研究。采用Revman 5.3软件进行系统评价和荟萃分析。结果9项研究共827例，其中试验组375例，对照组452例。Meta分析显示，简易智力状态检查量表 = 为1.5 2，95%CI为0.90，2.14；蒙特利尔认知量表为 = 3.5，95%CI为0.76，6.2 4；临床痴呆评定量表为 = −为0.5 5，95%CI为−0.80，−为0.2 9；逻辑记忆延迟回忆为 = 1.1，95%CI为0.0 4，2.16；前向数字跨度 = 为0.53，95%可信区间[−0.65，1.71]；后向数字跨度 = −为0.1，95%可信区间[−0.38，0.19]。纳入的文章中没有不良事件的报道。只有有限的证据支持练习太极对患有认知障碍的老年人有效。太极拳似乎是一种安全的运动，它能带来更好的认知功能分数的变化。
Cognitive decline occurs in all persons during the aging process and drugs can only alleviate symptoms and are expensive. Some researches demonstrated that Tai Chi had potential in preventing cognitive decline while others' results showed Tai Chi had no influence on cognitive impairment. Therefore, we conduct a systematic review and meta-analysis to assess the efficacy and safety of cognitive impairment patients practicing Tai Chi. A comprehensive literature search was carried out in multiple databases, including PubMed, Cochrane, MEDLINE (Ovid), Web of Science, Embase, Scopus, PsycInfo (Ovid), CKNI, Wan Fang, VIP, SinoMed, and ClinicalTrails, from their inception to 1 July 2020 to collect randomized controlled trials about practicing Tai Chi for patients with cognitive impairment. Primary outcomes included changes of cognitive function and secondary outcomes included changes of memory functions. Data were extracted by two independent individuals and Cochrane Risk of Bias tool version 2.0 was applied for the included studies. Systematic review and meta-analysis were performed by RevMan 5.3 software. The results included 827 cases in 9 studies, of which 375 were in the experimental group and 452 were in the control group. Meta-analysis showed that Mini-Mental State Examination WMD = 1.52, 95% CI [0.90, 2.14]; Montreal Cognitive Assessment WMD = 3.5, 95% CI [0.76, 6.24]; Clinical Dementia Rating WMD = −0.55, 95% CI [−0.80, −0.29]; logical memory delayed recall WMD = 1.1, 95% CI [0.04, 2.16]; digit span forward WMD = 0.53, 95% CI [−0.65, 1.71]; and digit span backward WMD = −0.1, 95% CI [−0.38, 0.19]. No adverse events were reported in the included articles. There is limited evidence to support that practicing Tai Chi is effective for older adults with cognitive impairment. Tai Chi seems to be a safe exercise, which can bring better changes in cognitive function score.
