Falls from beds and other household furniture are common scenarios stated to conceal child abuse. Knowledge of the biomechanics associated with short-distance falls may aid clinicians in distinguishing between abusive and accidental injuries. Computer simulation is a useful tool to investigate injury-producing events and to study the effect of altering event parameters on injury risk. In this study, a paediatric bed fall computer simulation model was developed and validated. The simulation was created using Mathematical Dynamic Modeling(®) software with a child restraint air bag interaction (CRABI) 12-month-old anthropomorphic test device (ATD) representing the fall victim. The model was validated using data from physical fall experiments of the same scenario with an instrumented CRABI ATD. Validation was conducted using both observational and statistical comparisons. Future parametric sensitivity studies using this model will lead to an improved understanding of relationships between child (fall victim) parameters, fall environment parameters and injury potential.
从床上和其他家具上跌落是据称可能掩盖虐待儿童行为的常见情况。了解与短距离跌落相关的生物力学知识可能有助于临床医生区分虐待性损伤和意外损伤。计算机模拟是研究致伤事件以及研究改变事件参数对受伤风险影响的有用工具。在本研究中，开发并验证了一个儿科床面跌落计算机模拟模型。该模拟使用数学动态建模（®）软件创建，采用一个代表跌落受害者的12个月大儿童约束气囊相互作用（CRABI）拟人测试装置（ATD）。该模型使用来自相同场景的带有仪器化CRABI ATD的物理跌落实验数据进行验证。使用观察性比较和统计性比较进行验证。使用该模型进行的未来参数敏感性研究将有助于更好地理解儿童（跌落受害者）参数、跌落环境参数与受伤可能性之间的关系。
