An anatomically based, multi-body model of the C5/C6 motion segment was developed to study soft-tissue neck injury mechanisms in rear impacts. This was integrated into the MADYMO-based van der Horst head and neck model.Responses were compared with volunteer test data up to head restraint impact. Soft-tissue loading was predicted for a series of rear-end vehicle crashes with crash recorders (n=78) and known long-term pain outcomes. Facet capsule shear and impingement injury mechanisms at C5/C6 were demonstrated. Facet capsule loading correlated well with NICmax and was able to predict the risk of AIS1 neck injuries with persisting pain. For the covering abstract see ITRD E134311.
