本研究旨在探讨太极拳对老年认知功能障碍患者认知功能的影响，并分析影响因素。我们检索了8个电子数据库，以获得截至2020年6月14日发表的关于TCC对认知功能影响的随机对照试验。采用PEDro量表评价纳入文献的方法学质量。采用Stata14.0软件进行Meta分析、亚组分析和发表偏倚检验。共纳入19项研究和1，970份样本。纳入文献的方法学质量一般至良好，无发表偏倚。总体而言，研究表明TCC对老年认知障碍患者的影响具有统计学意义（SMD = 0.31，p < 0.0001）。其中5个认知功能子领域是显著的调节因子[Q（5）= 15.66，p=0.008]，总体认知功能的效应量（ES）最大（SMD = 0.41），其次是执行功能（SMD = 0.33）、记忆（SMD = 0.31）和语言流畅性（SMD = 0.27）。关于运动处方变量，结果受运动训练长度的显著调节[Q（2）= 6.00，p=0.05]，中等长度的ES最大（SMD = 0.41），其次是短长度（SMD = 0.40）和长长度（SMD = 0.29）。然而，结果并不受会议时间或频率的影响。TCC可改善老年认知功能障碍患者的多项认知功能。干预效果受锻炼长度的调节，但不受锻炼时间和频率的调节。
This systematic and meta-analytic review aimed to investigate the effects of Tai Chi Chuan (TCC) on the cognitive function of the elderly with cognitive impairment and to analyze the moderators of these effects. We searched eight electronic databases for randomized controlled trials on the effects of TCC on cognitive function, published up to June 14, 2020. The PEDro scale was used to evaluate the methodological quality of the included literature. Stata14.0 software was used for meta-analysis, subgroup analysis, and publication bias testing. A total of 19 studies and 1,970 samples were included. The methodological quality of the included literature was fair to good, and there was no publication bias. Overall, the research shows that the effect of TCC on the elderly with cognitive impairment is statistically significant (SMD = 0.31, p < 0.0001). Five of the cognitive function subdomains were significant moderators [Q (5) = 15.66, p=0.008], and the effect size (ES) was the largest for global cognitive function (SMD = 0.41), followed by executive function (SMD = 0.33), memory (SMD = 0.31), and verbal fluency (SMD = 0.27). Regarding the exercise prescription variables, results were significantly moderated by the length of exercise training [Q (2) = 6.00, p=0.05], with ESs largest for moderate length (SMD = 0.41), followed by short length (SMD = 0.40) and long length (SMD = 0.29). However, the results were not moderated by session time or frequency. TCC can improve multiple cognitive functions of the elderly with cognitive impairment. The intervention effects are moderated by exercise length, but not by exercise session time and frequency.
