背景：福尔斯通常是由于对意外的外部扰动的反应失败而导致的。基于表现、基于反应和/或基于适应的评估工具是否能预测社区居住的老年人未来的福尔斯尚不清楚。目的：本初步前瞻性研究探讨了老年人未来跌倒风险与他们对重复滑倒的反应和适应以及他们的功能状态之间的关系。方法：13名居住在社区的成年人（>64岁）最初经历了一段反复滑倒的过程。大约30个月后，从这些参与者中收集了前一年自我报告的福尔斯经历数据。滑结果（跌倒，失去平衡，或恢复），滑得分（加权总和的滑结果），定时上升和去的分数，和未来的跌倒发病率recorded.Results：四名参与者谁报告至少有1个秋天有显着较高的滑分数比其余的。相比之下，无论是失败的恢复第一次滑倒，也没有更高的TUG评分预测未来的更大的几率福尔斯。结论：社区居住的老年人的适应性外部施加的扰动可能会揭示他们未来的跌倒风险。
Background: Falls often result from failed responses to unexpected, externally applied perturbations. Whether performance-based, reaction-based, and/or adaptation-based assessment tools can predict future falls among community-dwelling older adults is unknown.Purpose: This preliminary prospective study examined the relationship between older adults' future fall risk and their reactive responses and adaptations to repeated slips, and their functional status.Methods: Thirteen community-dwelling adults (>64 years) were exposed initially to a session of repeated slips. About 30 months later, self-reported falls experience data were collected for the preceding year from these participants. Slip outcome (fall, loss of balance, or recovery), slip score (weighted sum of slip outcomes), Timed Up and Go scores, and future fall incidence were recorded.Results: Four participants who reported at least 1 fall had significantly higher slip scores than the rest. In contrast, neither failed recovery on the first slip nor a higher TUG score predicted greater odds of future falls.Conclusion: Community-dwelling older adults' adaptability to externally imposed perturbations may reveal their future fall risk.
