摘要
目的:探讨高低音频-运动刺激模式对农村轻度认知障碍老年人注意力和记忆力的干预效果。方法:2019年9月至2020年5月选取符合纳入排除标准的轻度认知障碍老年人80名,抽签法分为试验组、对照组,每组40名。对照组给予手指保健操训练,试验组在手指保健操训练基础上,给予高低音频-运动刺激模式训练。分别于干预前后使用数字划销任务(number cancellation test,NCT)、基于Stroop效应设计的E-prime范式对持续性注意力和选择性注意力进行测评,使用Rivermead行为记忆测验第2版(Rivermead behavioral memory test,version 2,RBMT-Ⅱ)进行记忆力测评。使用SPSS 17.0软件进行数据统计。采用独立样本t检验,配对样本t检验,Mann-Whitney U检验进行统计分析。结果:干预后试验组持续注意力指数(0.86±0.48)显著高于对照组(0.63±0.47,t=4.336,P<0.05),干预后试验组的一致反应时[(2263.38±437.87)ms]和逆向反应时[(2335.75±599.86)ms]显著低于对照组[(2703.95±506.34)ms,(2667.43±585.38)ms](t=-4.068,-2.447,P<0.05),一致正确率[(0.84±0.14)]和逆向正确率[(0.87±0.10)]显著高于对照组[(0.71±0.19),(0.73±0.15)](t=3.571,4.931,均P<0.05)。干预后试验组RBMT-Ⅱ各维度及总标准分[19.00(18.00,20.00)分]均高于对照组[11.00(10.00,12.00)分](Z=7.299,P<0.05)。结论:高低音频-运动刺激模式对农村轻度认知障碍老年人注意力和记忆力有改善效果。
Objective To explore the intervention effects of high and low audio-motor stimulation mode on attention and memory of elderly with mild cognitive impairment in rural areas.Methods From September 2019 to May 2020,80 subjects with mild cognitive impairment meeting the inclusion and exclusion criteria were selected and randomly divided into experimental group and control group according to the drawing lots,with 40 participants in each group.The experimental group was given high and low audio-motor stimulation mode training,and the control group was given finger exercises training.Before and after the intervention,sustained and selective attention were assessed using number cancellation test(NCT),E-Prime paradigm based on Stroop effect design,and memory was assessed using the Rivermead behavioral memory test,version 2(RBMT-Ⅱ).SPSS 17.0 software was used to perform data statistics.The independent sample t test,paired sample t test and Mann Whitney U test were used for statistical analysis.Results After intervention,the sustained attention index of the experimental group(0.86±0.48)was significantly higher than that of the control group(0.63±0.47,t=4.336,P<0.05).After intervention,the unanimous response time of the experimental group((2263.38±437.87)ms)and the reverse reaction time((2335.75±599.86)ms)were significantly lower than those of the control group((2703.95±506.34)ms,(2667.43±585.38)ms)(t=-4.068,-2.447,P<0.05).The consistent correct rate((0.84±0.14))and the reverse correct rate((0.87±0.10))were significantly higher than those of the control group((0.71±0.19),(0.73±0.15))(t=3.571,4.931,both P<0.05).RBMT-Ⅱdimensions and total standard scores of the experimental group(19.00(18.00,20.00))were higher than those of the control group(11.00(10.00,12.00))(Z=7.299,P<0.05).Conclusion High and low audio-motor stimulation improves attention and memory in rural elderly with mild cognitive impairment.
