Biomechanics of fall-related impacts and balance in seniors

跌倒相关伤害是影响老年人的重要公共卫生问题。它们是老年人住院的主要原因，每年直接花费加拿大经济约28亿加元。特别值得关注的是髋部骨折和创伤性脑损伤（TBI），这两种损伤都是由福尔斯跌倒引起的，在老年人中高达90%。指导该建议的基本原则是，跌倒相关损伤的风险与施加到身体组织的载荷与组织强度的比率（称为风险系数）直接相关。因此，为了开发和实施循证干预措施，我们需要更深入地了解在跌倒相关影响期间影响施加到身体的负荷的变量，包括个人因素（年龄，性别，人体测量学），平衡控制因素（平衡恢复和保护性反应的策略）和外部工程设备。

Fall-related injuries are an important public health issue affecting seniors. They are the leading cause of hospitalizations in seniors and cost the Canadian economy approximately $2.8 billion in direct annual costs. Of particular concern are hip fractures and traumatic brain injuries (TBI), both of which are precipitated by falls in up to 90% of cases in older adults. The underlying principle that guides this proposal is that the risk of a fall-related injury is directly related to the ratio of loads applied to body tissues vs. the strength of the tissues (termed factor of risk). Consequently, to develop and implement evidence-based interventions we require greater insights into the variables that influence the loads applied to the body during fall-related impacts including individual factors (age, gender, anthropometrics), balance control factors (strategies of balance recovery and protective responses), and external engineering devices.
