BIOMECHANICS OF AVOIDING A FALL FOLLOWING A SLIP

描述：(逐字摘自应用程序) 目前提议的项目是减少老年人受伤的发生率 因滑倒而跌倒的成年人。我们将诱导受控滑行进入 年轻人和老年人使用专门设计的滑台。这个 目前提出的项目的目的是确定生物力学 变数限制了年轻人和老年人防止落后的能力 由于在运动过程中脚部向前滑行而摔倒。在……里面 特别是，我们将把注意力集中在后腿的防滑上，作为一种 恢复平衡和避免跌倒的关键组成部分。我们 假设在滑倒后避免跌倒是由 非滑脱小腿的生物力学和较高的跌倒速度 老年人可以归因于后部不打滑的生物力学 腿。如果假设得到支持，那么结果将为 进一步研究老年人可以通过哪些适当的方法做得更好 防止因滑倒而摔倒和受伤。我们将检验这些假设 通过解决以下具体目标。 具体目标1：描述区分能力的滑移条件 年轻人和老年人，以避免滑倒后摔倒。 具体目标2：描述区别不同关节的生物力学差异 年轻人和老年人在滑倒后避免摔倒的能力。 具体目标3：明确后腿防滑的重要性，以避免 一次又一次滑倒。 这项拟议工作的影响是它将量化生物力学 滑落事件结果的决定因素(恢复或下降)。这个 该项目与健康有关的特点是它将有助于进一步 系统地设计和测试可能有效的干预方法 减少因滑倒而受伤和死亡的人数，特别是老年人 成年人。

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.
