我们确定了分心对健康老年人和阿尔茨海默病(AD)患者步态的影响。采用重复测量设计和组间比较，比较了同时进行语言流畅任务(背诵男性或女性名字的效果)对步行30英尺所需时间和步数的影响，其中居住在社区的健康老年人(Oold；n=20；平均年龄+/-SD，86+/-4.4)、健康年轻老年人(yOld；n=23；平均年龄+/-SD，72+/-3.6)和可能的AD患者(n=15；平均年龄+/-SD，74+/-13)之间进行了组间比较。AD患者较老年组(p=0.005)和老年组(p=0.002)减慢更多。年龄与年龄差异无统计学意义(p=0.68)。平均(+/-SD)时间差为：Yold，-2.2+/-1.9；Oold，-1.6+/-2.0；AD，-7.1+/-9.2秒。步骤的变化在不同的组之间没有不同。在双重任务中，AD患者的步行速度比老年受试者慢得多。这可能会增加AD跌倒的风险。
We determined the effects of distraction on gait in healthy elderly subjects and Alzheimer's disease (AD) patients. The effects of simultaneous performance of a verbal fluency task (effect of reciting male or female names) on the time and number of steps taken to walk 30 feet were compared using a repeated-measures design with between-group comparison between community-dwelling healthy old old (oOld; n = 20; mean age +/- SD, 86 +/- 4.4), healthy young old (yOld; n = 23; mean age +/- SD, 72 +/- 3.6), and probable AD subjects without parkinsonism (n = 15; mean age +/- SD, 74 +/- 13). AD patients slowed more than the yOld (p = 0.005) and the oOld (p = 0.002). The yOld and oOld did not differ from each other (p = 0.68). Mean (+/-SD) differences in time were as follows: yOld, -2.2 +/- 1.9; oOld, -1.6 +/- 2.0; AD, -7.1 +/- 9.2 seconds. The change in steps did not differ between groups. Walking speed of AD patients slowed more than that of elderly subjects during the dual task. This may contribute to the risk of falls in AD.
