This meta-analysis of randomized controlled trials (published or unpublished RCTs in English) examined the effectiveness of dance interventions compared to waitlist/active controls on cognitive functions in patients with mild cognitive impairment (MCI). Literature search was conducted on MEDLINE, EMBASE, CINAHL and related databases through 3 August 2019. Risk of bias was assessed with the PEDro scale regarding randomization, allocation concealment, group comparability, blinding, attrition and selective reporting. Five included RCTs (N = 358) used Latin, ballroom and aerobic dances (frequency: 1−3 session/week; intensity: light to moderate; time: 25−60 min/session; type: aerobic). Results show that dance interventions improve global cognition (SMD [95 % CI] = 0.48 [0.21, 0.74]), attention (SMD [95 % CI] = 0.33 [0.12, 0.54]), immediate (SMD [95 % CI] = 0.54 [0.38, 0.71]) and delayed recall (SMD [95 % CI] = 0.33 [0.01, 0.64]), and visuospatial ability (SMD [95 % CI] = 0.16 [0.01, 0.32]). Study limitations include a small number of RCTs and high heterogeneity in some cognitive domains. In summary, dance interventions improve some cognitive domains in MCI.

这项对随机对照试验（英语已发表或未发表的RCT）的荟萃分析检验了轻度认知障碍（MCI）患者中舞蹈干预相对于认知功能候补/积极对照的有效性。文献检索截止到2019年8月3日在MEDLINE，EMBASE，CINAHL和相关数据库上进行。使用PEDro量表评估偏倚风险，涉及随机，分配隐瞒，组间可比性，盲目，损耗和选择性报告。包括5个RCT（N = 358），使用拉丁舞，舞厅舞和有氧舞蹈（频率：1-3节/周；强度：轻至中度；时间：25-60分钟/节；类型：有氧）。结果表明，舞蹈干预可提高整体认知度（SMD）[95％CI] = 0.48 [0.21，0.74]），注意力（SMD [95％CI] = 0.33 [0.12，0.54]），立即（SMD [95％CI] = 0.54 [0.38，0.71]）和延迟召回（SMD [95％CI] = 0.33 [0.01，0.64]）和视觉空间能力（SMD [95％CI] = 0.16 [0.01，0.32]）。研究局限性包括少数RCT和某些认知领域的高度异质性。总之，舞蹈干预可以改善MCI中的某些认知领域。（PROSPERO注册：CRD42019145418）
