Peculiarities of the Use of the DIERS Class Systems for the Analysis of the Condition of Spine and Lower Extremities in Rehabilitation Technologies

Abstract

The objective of the study is to analyze the characteristics of the functional and structural characteristics, the use of the modern DIERS class systems, for the analysis of the state of the spine and lower limbs in rehabilitation technologies.The main area of the research is the functional analysis of the musculoskeletal system (MSS).Attention in the research and development is given to light optical 3d/4d analysis of the spinal column and posture, pressure analysis of feet and walk, and the DIERS FAMUS line (analysis of the functionality of the muscular system).The system for the spine analysis works without X-rays for reduction of the high radiation load on a person during the resumption (treatment). This technology allows conducting the non-rayed topography of the human body and 3d-reconstruction of the spine. The system displays a large number of clinical parameters of objective and quantitative analysis of the body and posture, including scoliosis and all forms of spinal curvature. The Formetric technology analyzes the shape of the back without the necessity to place the markers. Anatomical landmarks (VP, SP, DL, DR), as well as the geometric axis of the back and spinal rotation automatically turn out to be a system.With the new generation of the DIERS 4d motion systems, a new level has been achieved in the field of spinal column analysis – for the first time it is possible to measure the spine and posture during movement of a person.This measurement technology is based on the physical principle of triangulation, because the system has an optical projector that projects a grid of lines on a person’s back, and the result is recorded by a video camera.Software (SW) analyzes the curvature of lines and simulates the 3d-surface of the back using photogrammetry. Unlike other systems, DIERS formtric, together with the back surface, produces a 3d-reconstruction of the spine without special markers.Automatic detection of the anatomical landmarks and using the scientific method of the correlation model which describes the relationship between the surface curvature and orientation of each vertebra, therefore, you can resume the spinal curve and measure the parameters of the pelvis.
