While focusing at accurate 3D joint kinematics, this paper explores the problem of how to perform a robust rigid registration for a sequence of object surfaces observed using standard 3D medical imaging techniques. Each object instance is assumed to give access to a polyhedral encoding of its boundary. We consider the case where object instances are noised with significant truncations and segmentation...
The aim of the present study is to develop a comprehensive, geometric, nonlinear finite element model of the occipito-atlanto-axial (C0-C1-C2) complex. More accurate geometric and material properties profited from Visible Human Male dataset which was introduced for the first time in the finite element research of the cervical spine. The biomechanical response of the model was validated and corresponded...
A four-segment biomechanical model and a control characterizing the action of the central nervous system (CNS) are used to investigate optimization of the postural stabilization process and the execution of voluntary movement. The point-to-point voluntary movement is optimized using different measures of performance (cost functions) in the time- and frequency domains. In particular kinematic measure...
Will being an important part of modern operation room, in recent years computer-aided technology has become more and more integrated in different surgical procedures, such as brain, spine, ENT, hip, knee etc. A vast number of papers have been published on computer assisted knee surgery recently with inspiring clinical results, such as more precise alignment and more minimally invasive. An innovative...
The purpose of this study was to calculate three-dimensional angular displacements, moments and joint reaction forces of the ankle joint during the waist pulling, and then, we assessed the reaction forces and bone-on-bone forces within ankle joint during postural balance control movement. With experiments and MATLAB simulation we could calculate ankle joint kinematic and kinetic data. The results...
