Technology Transfer in Biokinematics of the Human Spine

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 paper presents an extensive literature search in the bio-kinematics of human spine and discusses the opportunities for technology transfer in theoretical kinematics to study the mechanics of human spine.

Application of Line geometry to theoretical kinematics and the kinematic analysis of mechanical systems

The theory of screws as developed by R. S. Ball, is concerned principally with rigid-body motions in three-dimensional Euclidean space. A number of scattered references, notably F. Klein [18], have mentioned algebraic approaches to the subject. In this paper which is essentially tutorial, we have used concepts of line geometry in order to present such a self-contained algebraic formulation. Other approaches to the subject, which are not considered here, are possible and useful: for example, motor algebra (F. M. Dimentberg) and surface geometry (K. H. Hunt, K. J. Waldron). The algebraic treatment is both general and well-adapted to kinematic analysis and numerical methods. These applications have been described.
