摘要：

目的:探索不同认知任务对轻度认知障碍(mild cognitive impairment,MCI)和正常老年人(normal cognition,NC)步行速度和双重任务消耗(dual-task costs,DTC)的影响。方法:根据最新诊断标准入组MCI和NC老年人,采用2m长的电子步道进行双重任务步态采集。每位受试者完成一项单任务步行和4项不同认知任务的双重任务步行(步行+计算,步行+说动物名,步行+记忆故事,步行+记忆词语)。计算不同任务下的步行速度和DTC并分析其组间差异。DTC是指单任务和双重任务步行速度之间差异的百分比:[(单任务速度-双重任务速度)/单任务速度]×100%。结果:本研究入组MCI老年人18人和NC老年人25人。两组间年龄、性别、教育年限等基线数据组间没有差异(P>0.05)。MCI和NC的四个不同认知任务之间存在显著性差异(P=0.004,P=0.010)。MCI仅有记忆单词下双重任务步行速度的DTC显著高于NC组(P=0.034)。结论:MCI和NC老年人不同认知任务下的DTC存在显著性差异。MCI老年人记忆单词的双重任务DTC显著高于正常老年人。
