这项初步研究调查了直接测量头部旋转是否改善了对轻度创伤性脑损伤(MTBI)的预测。虽然许多研究表明旋转是mTBI的主要原因，但监管安全标准使用仅3自由度(3DOF)平移的运动学标准来预测损伤。直接测量人体头部旋转(3DOF)和平移(3DOF)的6自由度是否可以检验额外的自由度是否能改善损伤预测，这在以前是不存在的。我们使用6自由度仪表式护口器测量了美式足球、拳击和混合武术中的头部撞击，并使用12个现有的运动学标准和6个现有的脑有限元(FE)标准预测了临床医生诊断的损伤。在513个测量的撞击中，前两个6个自由度的测量是临床诊断的mTBI。对于该数据集，6DOF标准是最能预测损伤的标准，超过3DOF仅平移和3DOF仅旋转标准。6自由度有限元标准中的主应变峰值是最强的预测指标，其次是旋转测量、旋转加速度峰值和头部冲击力(HIP)。这些结果表明，头部旋转测量可能会改善损伤预测。然而，需要更多的6DOF数据来证实对现有损伤标准的评估，并开发考虑损伤方向性敏感性的新标准。
This preliminary study investigated whether direct measurement of head rotation improves prediction of mild traumatic brain injury (mTBI). Although many studies have implicated rotation as a primary cause of mTBI, regulatory safety standards use 3 degree of freedom (3DOF) translation-only kinematic criteria to predict injury. Direct 6DOF measurements of human head rotation (3DOF) and translation (3DOF) have not been previously available to examine whether additional DOFs improve injury prediction. We measured head impacts in American football, boxing, and mixed martial arts using 6DOF instrumented mouthguards, and predicted clinician-diagnosed injury using 12 existing kinematic criteria and 6 existing brain finite element (FE) criteria. Among 513 measured impacts were the first two 6DOF measurements of clinically-diagnosed mTBI. For this dataset, 6DOF criteria were most predictive of injury, more than 3DOF translation-only and 3DOF rotation-only criteria. Peak principal strain in the corpus callosum, a 6DOF FE criteria, was the strongest predictor, followed by two criteria that included rotation measurements, peak rotational acceleration magnitude and Head Impact Power (HIP). These results suggest head rotation measurements may improve injury prediction. However, more 6DOF data is needed to confirm this evaluation of existing injury criteria, and to develop new criteria that considers directional sensitivity to injury.
