Validation of the neck injury criterion (NIC) using kinematic and clinical results from human subjects in rear-end collisions

In this study, neck injury criterion (NIC) values were calculated using human subject kinematic data and compared to their clinical results. Twenty-nine percent and 38% of the subjects exhibited whiplash-associated disorders (WAD) at rear-end speed changes of 4 and 8 km/h, respectively. None of the subjects' NIC values exceeded 15 m2/s2, which had been proposed as a tolerance level for Abbreviated Injury Scale (AIS) 1 cervical injury. NIC was not able to predict the presence of symptoms in the test population. This may be due to differences between the subjects' anatomical source of pain and the nature and type of injury predicted by NIC. (A) For the covering abstract of the conference see ITRD E203725.
