Optical Measurement of 6-DOF Kinematics of Internal Body Structures During Frontal Impact Restraint Loading

This paper presents an optical method for measuring motion of internal body structures during impact. Orthogonal arrays of reflective markers are mounted to bones via rigid rods. The motion of the array is measured in an inertial coordinate system and transformed using computed tomography and rigid body dynamics to determine 6-DOF kinematics of the anatomical structure to which the array is mounted. Local 6-DOF kinematics of the ribs, sternum, and vertebrae during frontal impact belt loading are presented.
