Recently, several cases of mild traumatic brain injury to American professional football players have been reconstructed using instrumented Hybrid III anthropomorphic test dummies ATDs. The translational and rotational acceleration responses of injured and uninjured players' heads have been documented. The acceleration data have been processed according to all current head injury assessment functions including the GSI, HIC and GAMBIT among others. A new hypothesis is propounded that the threshold for head injury will be exceeded if the rate of change of kinetic energy of the head exceeds some limiting value. A functional relation is proposed, which includes all six degrees of motion and directional sensitivity characteristics, relating the rate of change of kinetic energy to the probability of head injury. The maximum value that the function achieves during impact is the maximum power input to the head and serves as an index by which the probability of head injury can be assessed.
最近，利用配备仪器的混合III型人体模拟试验假人（ATD）对几例美国职业橄榄球运动员的轻度创伤性脑损伤案例进行了重建。已记录了受伤和未受伤球员头部的平移和旋转加速度响应。加速度数据已根据所有当前的头部损伤评估函数进行处理，包括广义严重性指标（GSI）、头部损伤标准（HIC）和GAMBIT等。提出了一个新假设，即如果头部动能的变化率超过某个极限值，就会超过头部损伤阈值。提出了一种函数关系，其中包括所有六个运动自由度和方向敏感性特征，将动能变化率与头部损伤概率联系起来。该函数在撞击过程中达到的最大值是输入到头部的最大功率，并作为评估头部损伤概率的一个指标。
