背景以前的研究表明，一个单一的会议反复滑暴露可以减少超过40%的实验室诱导的老年人福尔斯下降。本研究的目的是确定在多大程度上这种扰动训练翻译为减少老年人的年度福尔斯的风险，在他们的日常生活。212名居住在社区的老年人（≥ 65岁）被随机分配到训练组（N = 109）和对照组（N = 103）中，训练组随后暴露于24次未经通知的重复滑倒，对照组在相同的保护性实验室环境中在相同的步行过程中仅经历一次滑倒。我们记录了他们在前一年（通过自我报告的历史）和在接下来的12个月（通过福尔斯日记和电话监测）的福尔斯。通过这一单次的重复滑动暴露，训练将老年人每年福尔斯跌倒的风险降低了50%（从34%降低到15%，p <0.05）。在相同的12个月随访期间，仅经历一次滑倒的人比经历24次重复滑倒的人跌倒的可能性高2.3倍（p <0.05）。这种训练效果在有跌倒史者中尤为突出。一个单一的会议反复滑暴露可以提高社区居住的老年人的弹性姿势障碍，因此，显着降低他们的年度风险福尔斯。
Background. Previous studies indicated that a single session of repeated-slip exposure can reduce over 40% of laboratory-induced falls among older adults. The purpose of this study was to determine to what degree such perturbation training translated to the reduction of older adults' annual falls risk in their everyday living.Methods. Two hundred and twelve community-dwelling older adults (>= 65 years old) were randomly assigned to either the training group (N = 109), who then were exposed to 24 unannounced repeated slips, or the control group (N = 103), who merely experienced one slip during the same walking in the same protective laboratory environment. We recorded their falls in the preceding year (through self-reported history) and during the next 12 months (through falls diary and monitored with phone calls).Results. With this single session of repeated-slip exposure, training cut older adults' annual risk of falls by 50% (from 34% to 15%, p < .05). Those who experienced merely a single slip were 2.3 times more likely to fall during the same 12-month follow-up period (p < .05) than those who experienced the 24 repeated slips. Such training effect was especially prominent among those who had history of falls.Conclusion. A single session of repeated-slip exposure could improve community-dwelling older adults' resilience to postural disturbances and, hence, significantly reduce their annual risk of falls.
