Abstract Compared to adults, it has been documented that children are at elevated risk for concussion, repeated concussions, and experience longer recovery times. What is unknown, is whether the developing brain may be injured at differing strain levels. This study examined peak and cumulative brain strain from 20 cases of concussion in both young children and adults using physical reconstructions and finite element modelling of the brain response to impacts. The child group showed lower impact kinematics as well as strain metrics. Results suggest children may suffer concussive injuries with lower brain strains compared to adults.

由跌倒引起的模拟脑应变在幼儿和成人的脑震荡事件之间有所不同

摘要 与成人相比，儿童脑震荡、反复脑震荡的风险更高，恢复时间更长。未知的是发育中的大脑是否会在不同的应变水平下受伤。这项研究使用物理重建和大脑对冲击反应的有限元建模，检查了 20 例幼儿和成人脑震荡的峰值和累积脑应变。儿童组表现出较低的冲击运动学和应变指标。结果表明，与成人相比，儿童可能遭受脑震荡较低的脑震荡。
