OBJECTIVE
The purpose of this study was to determine whether healthy adult volunteers report symptoms following exposure to low-speed frontal crashes at low velocities.
METHODS
Nineteen medically screened, healthy, informed, and willing volunteers (17 men, 2 women; mean age, 37 years) were exposed to low-speed frontal crashes. All volunteers were seated in the rear seat position of the bullet vehicle. Closing velocities ranged from 4.1 to 8.3 mph (mean, 6.7 mph). For the bullet vehicle, the delta V ranged from 1.4 to 3.9 mph with a mean of 2.8 mph.
RESULTS
Eighty-eight percent of volunteers attributed symptoms of discomfort to their crash exposure. All reported symptoms were transient, and none required medical treatment. The mean duration was 1 day.
CONCLUSIONS
Even at relatively low speeds, there is no lower threshold below which it can be reasonably assumed that healthy and prepared volunteer rear seat passengers will not sustain some level of minor injury in a frontal collision. Although the reported mean delta V for injured persons in real-world frontal crashes has been reported to be as high as 8.1 mph, this does not offer any insight into the minimum threshold for such injuries among all at-risk vehicle occupants.
目的
本研究旨在确定健康成年志愿者在遭遇低速正面碰撞后是否会报告出现症状。
方法
19名经过医学筛查、健康、知情且愿意参与的志愿者（17名男性，2名女性；平均年龄37岁）遭遇了低速正面碰撞。所有志愿者均坐在撞击车辆的后排座位。碰撞速度范围为每小时4.1至8.3英里（平均每小时6.7英里）。对于撞击车辆，速度变化范围为每小时1.4至3.9英里，平均为每小时2.8英里。
结果
88%的志愿者将不适症状归因于碰撞。所有报告的症状都是短暂的，且无人需要接受治疗。平均持续时间为1天。
结论
即使在相对较低的速度下，也不存在一个较低的阈值，据此可以合理假定健康且有准备的后排座位志愿者乘客在正面碰撞中不会受到一定程度的轻伤。尽管据报道现实世界中正面碰撞受伤者的平均速度变化高达每小时8.1英里，但这对于所有有风险的车辆乘员中此类损伤的最低阈值并无任何启示。
