Design and simulation of spine affected by scoliosis and proposition of dynamic brace

Abstract

This paper deals with 2D, and 3D simulations of a human equipped with back bone pitch and roll joints to study the advantages of having such a mechanism for daily human-like movements. A comparison between a normal spine and deformed spine due to scoliosis is made. The contribution of this paper consists of designing the mechanism for correcting abnormal postures of the human spine, taking into account the specifications of forward, backward and left/right sideways bending amplitudes. The mechanism is 2 legs mechanism composed of a bottom platform and a top platform connected by two articulated arms and a vertical central rod.
