תקציר

An analysis of spinal configuration during the act of dynamic lifting is described. The methodology for data collection is based on a computerized spot detection system and a video recording setting. Data were obtained in a factorial design for a variety of lifting tasks, performed by male and female subjects in a laboratory spinal geometry, by means of angular displacements in four regions along the spinal column, is studied to assess the architectural changes created by the balancing forces during the lifting act. On this basis, two-dimensional geometrical changes of the spine during lifting have been evaluated. The analysis allows to discuss the objective effects of lifting postures, horizontal reach distances and load weights on spinal changes during the different phases of the lifting act. Interactions between practical lifting parameters reveal the effects of lifting variables on postural deviation as performed by the spinal system. Relevance to industry: Geometrical measures of spinal configuration during lifting are important for simulation of working postures, design of job requirements and modeling of the human spine. The analysis of spinal segment angular displacement is essential to enhance the practical design of manned work stations and contributes to the scientific effort directed toward the prevention of back injury.
