PROJECT SUMMARY Falls are the leading cause of accidental injury and death among older adults. Fall related injuries occur when the impact force of the fall is greater than tissue strength. An alternative approach to current practice is teaching older adults protective movements that reduce the impact force when they to fall. This high risk/high reward approach is fundamentally different from traditional approaches in injury prevention. There is evidence that teaching safe landing strategies (i.e. movement patterns) can significantly reduce hip impact forces and head acceleration in young adults. Recent pilot data suggests that older adults can learn to fall so that they minimize their impact forces and head acceleration. However, the sample was limited to older adults with minimal risk of falls. Consequently it is not clear if older adults at risk of falls can safely learn to fall safely. The ultimate goal of this innovative proposal is to set the stage for the development of a novel approach to reduce fall related injuries in older adults. The immediate goal of this proposed R21 is to determine the feasibility of Falling Safely Training program in an at-fall risk older adult group, the key measureable stages of FAST mastery, and, most importantly, the effect size, compared to Otago Exercise Program (an evidence- based fall risk reduction program) controls, to inform a larger future trial. The current investigation, is a necessary step, to determine if teaching older adults at risk of falls in a standardized progressive program is safe (Aim 1), and whether at risk older adults can learn to fall with reduced head acceleration and hip impact forces (Aim 2). 28 participants will be randomized into one of two groups (fall training or balance training). All participants will perform standardized sideway falls and have their hip impact and head acceleration quantified utilizing validated techniques. Participants will undergo 8 standardized progressive training sessions, undergo baseline and post training assessments and a 3-month follow-up session. Consistent with the principles of motor learning, learning will be quantified with changes in hip impact force and head acceleration following training, and 3-month retention. The overall goal of this project is to systematically determine whether training older adults to fall safely has potential utility as a strategy to reduce fall-related injuries which can be combined with current fall prevention efforts.

项目摘要 福尔斯是老年人意外伤害和死亡的主要原因。跌倒相关伤害发生在 坠落的冲击力大于组织强度。现行做法的另一种做法是 教老年人保护性动作，减少他们跌倒时的冲击力。高风险/高风险 奖励方法与传统的伤害预防方法有着根本的不同。 有证据表明，教授安全着陆策略（即运动模式）可以显著降低髋关节 冲击力和头部加速度。最近的试点数据表明，老年人可以学会 使他们的冲击力和头部加速度最小化。然而，样本仅限于年龄较大的 福尔斯跌倒风险最小的成年人。因此，尚不清楚有福尔斯跌倒危险的老年人是否能安全地学会跌倒 平安 这一创新提案的最终目标是为开发一种新的方法奠定基础， 减少老年人跌倒相关的伤害。这一拟议的R21的直接目标是确定 在有跌倒风险的老年人群体中实施安全跌倒训练计划的可行性， 快速掌握，最重要的是，效果大小，与奥塔哥锻炼计划相比（证据- 基于跌倒风险降低计划）的控制，以告知未来更大的试验。目前的调查，是一个 必要的一步，以确定是否教学老年人在福尔斯的风险，在一个标准化的渐进计划， 安全（目标1），以及处于风险中的老年人是否可以在头部加速度和臀部撞击降低的情况下学会跌倒 力（目标2）。28名参与者将被随机分为两组（跌倒训练或平衡训练）。所有 参与者将进行标准化的侧倒福尔斯，并对其臀部冲击和头部加速度进行量化 使用经过验证的技术。参与者将接受8次标准化的渐进式培训， 基线和培训后评估以及3个月的随访。符合以下原则： 运动学习，学习将随着以下髋关节冲击力和头部加速度的变化而量化 培训和3个月的保留。本项目的总体目标是系统地确定培训是否 老年人安全跌倒作为一种减少跌倒相关伤害的策略具有潜在的实用性， 目前的预防措施。
