Abstract: A three-dimensional motion simulation model of an open-loop kinematically constrained mechanical system is developed to simulate the motion response of a robotic arm to externally applied static ...

Abstract: The present paper examines the role of theoretical kinematics of rigid body motion in solving some of the basic research problems in the study of intervertebral motion in human spine. The ...

Abstract: Facet joints provide rigidity to the lumbar motion segment and thus protect the disk, particularly against torsional injury. A surgical procedure that fully or partially removes the facet joints ...

Abstract: The paper presents the kinematic analysis of motion segments of ten, human-lumbar spines. In order to achieve this objective, a spine fixture and a linkage transducer were designed. The spine ...

Abstract: Based on the earlier work by the author on the development of a theoretical motion simulation model of an open-loop, kinematic chain, the present paper examines the motion characteristics of ...

Abstract: The technique used to incise the disc during discectomy may play a role in the subsequent healing and change in biomechanical stiffness of the disc. Several techniques of lumbar disc annulotomy ...
