Because of the increasing protection offered by recent cars, the neck has become a challenging question during the past decade. However, no biofidelic tool for low speed rear-end impact is available at the moment, and additional biomechanical data are still needed to refine the existing dummies or numerical models. Within the framework of the European project "Whiplash", we carried out several tests aiming at obtaining a detailed description of the human neck behaviour in low speed rear-end impact. The emphasis was put on the kinematics acquisition at different vertebral levels.
