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：（逐字化的应用程序）的长期目标目前建议的项目是减少年龄较大的伤害的发生率与滑动相关的成年人跌倒。我们将在年轻人和老年人使用专门设计的滑动平台。这目前建议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向后的能力在移动过程中，由于脚向前倾斜而跌落。在特别是，我们将注意力集中在非滑动后腿上恢复平衡并避免跌倒的关键组成部分。我们假设避免在滑动后避免跌倒是由非滑腿的生物力学，并且降低的速度较高老年人可以归因于非滑动后的生物力学腿。如果支持假设，则结果将为进一步调查老年人可以更好的适当手段免受与滑动相关的瀑布和伤害的保护。我们将检验这些假设通过解决以下特定目标。特定目标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。特定目的2：表征区分生物力学差异年轻人和老年人避免滑倒后跌倒的能力。特定目标3：定义非滑动，后腿的重要性滑倒后跌倒。拟议工作的影响是它将量化生物力学下滑事件结果（恢复或跌落）的决定因素。这该项目的健康相关性是它将有助于进一步可能有效的干预方法的系统设计和测试减少与滑动相关的伤害和死亡的数量，尤其是在年龄较大的成年人。
