项目摘要

DESCRIPTION: (verbatim from application) The long-term objective of the presently proposed project is to reduce the incidence of injuries to older adults that result from slip-related falls. We will induce controlled slips in young and older adults using a specially designed slipping platform. The purpose of the presently proposed project is to determine the biomechanical variables limit the ability of young and older adults to prevent a backward fall as a result of a forward-directed slip of the foot during locomotion. In particular, we will focus our attention on the non-slipping rear leg as a crucial component of recovering one's balance and avoiding a fall. We hypothesize that avoidance of a fall subsequent to a slip is dictated by the biomechanics of the non-slipping leg and that the higher rate of falling by older adults can be attributed to the biomechanics of the non-slipping rear leg. If the hypotheses are supported then the results will provide support for further investigating appropriate means by which older adults can be better protected from slip-related falls and injuries. We will test these hypotheses by addressing the following Specific Aims. Specific Aim 1: characterize the slip conditions that distinguish the ability of young and older adults to avoid a fall after slipping. Specific Aim 2: characterize the biomechanical differences that distinguish the ability of young and older adults to avoid a fall after slipping. Specific Aim 3: define the importance of the non-slipping, rear leg to avoiding a fall after slipping. The impact of the proposed work is that it will quantify biomechanical determinants of the outcome (recovery or fall) of a slipping event. The health-relatedness of the project is that it will contribute to further systematic design and testing of intervention methods that may effectively reduce the number of slip-related injuries and deaths, particularly in older adults.

描述：（申请中逐字逐句）该项目的长期目标目前提议的项目是减少老年人受伤的发生率因滑倒导致的成年人。我们将诱导受控滑移年轻人和老年人使用专门设计的滑动平台。这目前提出的项目的目的是确定生物力学变量限制了年轻人和老年人防止落后的能力因运动过程中脚向前滑动而跌倒。在特别是，我们将重点关注防滑后腿作为恢复平衡和避免跌倒的重要组成部分。我们假设避免滑倒后的跌倒是由防滑腿的生物力学以及较高的跌倒率老年人可以归因于防滑后部的生物力学腿。如果假设得到支持，那么结果将支持进一步研究使老年人能够更好地生活的适当方法防止滑倒和受伤。我们将测试这些假设通过解决以下具体目标。具体目标1：表征区分能力的滑移条件年轻人和老年人避免滑倒后跌倒。具体目标 2：表征区分不同个体的生物力学差异年轻人和老年人滑倒后避免跌倒的能力。具体目标 3：明确后腿防滑对于避免滑倒的重要性滑倒后摔倒。拟议工作的影响在于它将量化生物力学滑倒事件结果（恢复或跌倒）的决定因素。这该项目与健康的相关性在于它将有助于进一步系统地设计和测试可以有效地干预的方法减少与滑倒相关的伤害和死亡数量，特别是老年人成年人。
