Abstract
The present scientific review of medical and technical literature presents the attempt to assess modern technological stage of spine biomechanical hardware diagnostics in terms of its objectivity, as well as diagnostic and prognostic value on the example of etiopathogenesis analysis of spine degenerative-dystrophic diseases. A set of structural and extra vertebral factors contributing to the onset and progression of spine degenerative-dystrophic diseases was identifi ed to determine diagnostic and prognostic value studying particular literature sources, which use empirical and mathematical research methods. Central indicator value of intersegmental compression-distractive kinetics and loads shift s related to these factors was also determined. When considering the objectivity of spine biomechanics video analysis, the reliability of kinetics and spinal motion segments kinematics was separately assessed. Furthermore, impropriety of the latter was established in terms of reliability and repeatability of diagnostic results. Only vertical force indicator is valid in kinetics, reflecting intersegmental compression load, due to the sufficient objectivity and weak dependence of its values on the type of computer mathematical models used by commercial systems of video motion analysis. Walking is optimal motional act for calculating vertical force by modern optoelectronic soft ware and hardware systems.
