Abstract

The study of a human operator's trunk-spine system dynamics is a difficult one, owing to the great number of degrees of freedom of the mechanical system and the postural regulation mode complexity (reflex, proprioceptive, exteroceptives loops). A good knowledge of these phenomena may be applied to the research on aviations and earthmover operator's spinal traumatisms.

In order to have a better knowledge of the postural regulation applied to the mechanical trunk-spine system; this paper presents the results of a study concerning the spinal curvature variations in the sagittal plane of an operator submitted to acceleration in a horizontal plane.

After a brief survey of the material and experimental setup characteristics, this paper present a statistical and frequential analysis applied to the recordings obtained concerning spine curvature variations. The results of this process lead to a simplified model of the trunk-spine system. The last paragraph refers to the simulation of this model on an analog computer and its validity.
