摘要: 目的 探讨认知双重任务对平衡功能的影响,分析平衡维持的感觉策略。方法 2015年6月至2016年6月,34例健康青年随机分为对照组(n=17)和观察组(n=17),在动态平衡仪上进行改良临床平衡测试。2周后,对照组再次进行测试,观察组在测试时加心算任务。记录站立在硬面和软垫上,睁眼、闭眼状态下的质心摆动速度和质心摆动速度综合值。结果 第2次测量时,对照组闭眼软垫站立时,质心摆动速度较第1次降低(t=2.535, P<0.05);观察组睁眼软垫站立时,质心摆动速度较第1次增加(t=-2.220, P<0.05),与对照组相比明显增加(t=-3.128, P<0.01);质心摆动速度综合值对照组较第1次明显降低(t=3.007, P<0.01),观察组较第1次增加(t=-2.170, P<0.05),两组间有显著性差异(t=-2.143, P<0.05)。结论 健康青年在加入认知任务后,平衡功能被干扰,特别是睁眼软垫站立时更明显;执行两种或以上任务时,感觉系统优先分配维持平衡。

Abstract: Objective To explore the influence of cognitive-dual task on balance function and analyze the sensory strategy of balance maintained.Methods Form June, 2015 to June, 2016, 34 healthy young people were randomly divided into control group (n=17) and observation group (n=17). They were tested with the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) on Neurocom Balance Manager, and retested two weeks later, while the observation group completed mental arithmetic cognitive task simultaneously. The center of gravity (COG) sway velocity and the comprehensive sway velocity were measured in both eyes open (EO) and eyes closed (EC) standing on firm or foam support.Results For the second test, The COG sway velocity decreased in the control group as EC standing on foam support (t=2.535, P<0.05), while it increased in the observation group as EO standing on foam support (t=-2.220, P<0.05), and it was more than that in the control group (t=-3.128, P<0.01). The comprehensive sway velocity decreased in the control group (t=3.007, P<0.01), but increased in the observation group (t=-2.170, P<0.05), which was significantly different between two groups (t=-2.143, P<0.05).Conclusion Cognitive tasks may interfere balance function in healthy youth, especially in the condition of EO standing on foam support. Sensory resource may preferer to meet the balance maintained during cognitive-dual tasks.
