舞蹈改善轻度认知障碍老年人认知功能和平衡能力的系统综述

Effect of Dance Intervention on Cognitive Function and Balance Function in Elderly with Mild Cognitive Impair‐ment:A Systematic Review

目的系统综述舞蹈对轻度认知障碍(MCI)老年人认知功能和平衡能力的干预效果。方法检索Cochrane图书馆、PubMed、CBM、WebofScience、Embase、中国知网、维普、万方等数据库,收集建库至2021年6月7日公开发表的关于舞蹈干预对轻度认知障碍老年人认知功能和平衡能力影响的随机对照试验研究,通过Cochrane偏倚风险评估工具对文献质量进行评价。结果最终纳入英文文献6篇,中文文献2篇,均为随机对照试验,整体研究质量较高。舞蹈干预组的简易精神状态检查(MMSE)、蒙特利尔认知评估量表(MoCA)评分显著高于对照组,在韦氏记忆量表(WMS)、连线测试(TMT)-B和言语流畅性任务中成绩优于对照组,但是对执行功能TMT-A反应时的改善效果不明显。舞蹈干预有助于提高MCI老年人的Berg平衡量表评分。结论舞蹈干预显著改善轻度认知障碍老年人的整体认知功能、记忆功能、执行功能和平衡能力。

Objective To explore the effect of dance intervention on the cognitive function and balance function in the elderly with mild cognitive impairment and its possible mechanism through systematic review of related literatures.Methods The literatures of randomized controlled trials on the impact of dance intervention on the cognitive function and balance function of the elderly with mild cognitive impairment were searched in the Cochrane library,PubMed,CBM,Web of Science,EMBASE,CNKI,VIP,Wanfang data and other databases,from establishment to June 7th,2021.Two researchers screened the literature according to the inclusion and exclusion criteria,extracted data,and evaluated the quality.Results The scores of Mini-Mental State Examination(MMSE)and Montreal Cognitive Assessment(MoCA)were better in the dance intervention experimental group than in the control group,as well as the scores of Wechsler Memory Scale(WMS),Trail Making Test(TMT)-B and Verbal Fluency Test.However,no significant difference was found in the response time in TMT-A between two groups.Dance intervention could improve the scores of Berg Balance Scale.Conclusion Dance intervention can improve overall cognitive function,memory function,executive function and balance function of the elderly with mild cognitive impairment.
