Investigation of drivers poses influence to the intervertebral forces in the junction of thoracic and lumbar spinal curves

Abstract

The investigation was performed with purpose to establish correlation between drivers pose and interverteb-ral forces in junction of thoracic and lumbar spinal curves with vertical direction kinematical upward impact. An mo-del created for analyzis, it consist of manikin and envin-ronment. Between manikins vertebras are placed contact elements which monitor intervertebral force changes. Du-ring simuliation there was changed manikins hip and knee settings and monitored changes of intervertebral forces. According stated rezults of this investigation, there was established driver pose with lowest intervertebral force values.
