Abstract: Despite the use of homologated Child Restraint Systems, children are still vulnerable on roads. This social and economic major issue is explained by the lack of biomechanical knowledge on injury mechanisms and associated physical parameters, specifically for children. The present project was supported by the GDR “Biomécanique des chocs“ (CNRS/INRETS/GIE PSA Renault) and funded by the French National Research Agency.
The aim of this study is to improve the biomechanical knowledge of the children trunk. In order to improve the reliability of children models, subject-specific inertial parameters of the body segments were calculated using 3D reconstructions from low dose biplanar X-rays. The fine description of the ribs, costal cartilage and sternum was performed on 3D models from CT-scan. The 3D geometry of the intra-abdominal child organs (kidney, spleen and liver) was defined by measurements based upon 3D modeling using abdominal CT-scan.
The quantification of the thoracic and abdominal behaviors was obtained in observing in vivo trunk manipulations carried out within the framework of usual physiotherapist treatments.
This research will be used to improve or develop the trunk bio-fidelity of child models and constitute a first step toward an enhanced knowledge of the child biomechanics based directly on in vivo experimentation.
