有氧舞蹈对轻度认知障碍患者认知和运动功能的影响

Effects of aerobic dance on cognitive and motor functions in patients with mild cognitive impairment

目的:探讨自主设计的有氧舞蹈对轻度认知障碍(MCI)患者认知和运动功能的干预作用。方法:将MCI患者随机分为运动组和对照组,运动组接受35min/次、3次/周、为期3个月的有氧舞蹈,对照组仅接受健康宣教。所有受试者在干预前、干预3月后、入组6个月随访时接受认知功能和运动功能评估。结果:干预前,两组的基线评估结果无显著性差异(P>0.05)。3个月有氧舞蹈干预后,运动组简易精神状态评分(mini-mental state examination,MMSE)、蒙特利尔认知评估(Montreal cognitive assessment,MoCA)评分、韦氏逻辑记忆测试评分、连线测试-A所需时间和连线测试-B所需时间与干预前比较均有显著性差异(P<0.05);韦氏逻辑记忆量表评分,连线测试-B所需时间与对照组比较有显著性差异(P<0.01,P<0.05)。随访时运动组MoCA评分,韦氏逻辑记忆测试评分、连线测试-A与干预前比较有显著性差异(P<0.05)。3个月干预后,运动组Berg平衡量表评分与干预前和对照组比较差异均有显著性意义(P<0.05)。结论:有氧舞蹈能够改善MCI患者的认知功能和运动功能。

Objective:To investigate the effects of aerobic dance on cognitive and motor functions in patients with mild cognitive impairment.Method:Sixty patients were randomized into treatment group and the control group in the single-blinded design.The treatment group accepted aerobic dance for 35 minutes a session with 3 times a week for 3 months.Minimental state examination(MMSE),Montreal cognitive assessment(Mo CA),Wechsler memory scale-revised(WMS-R),and trail making test(TMT)-A and TMT-B were used to assess the cognitive function and rate pressure product(RPP),metabolic equivalent(METs),max heart rate(HRmax)and Berg balance scale(BBS)were used to assess the motor function of each patient at baseline,3 months,and 6 months of follow-up.Result:The characteristics of patients in the aerobic dance group and control group were similar at baseline.Fifty-four patients completed the intervention and follow-up.The scores of MMSE,Mo CA,WMS-R,TMT-A and TMT-B in treatment group significantly improved after 3 months’aerobic dance compared with the baseline(P<0.05).The scores of WMS-R,TMT-B in treatment group significantly improved after 3 months’aerobic dance compared with the control group(P<0.05).The scores of WMS-R,TMT-A significantly improved in treatment group at 6 months of follow-up compared with the baseline.The score of BBS improved in treatment group at 6 months of follow-up compared with the baseline and the control group.Conclusion:Aerobic dance improves the cognitive and motor function in patients with MCI.
