Abstract

The socket for lower limb prosthesis is the central element of artificial leg that needs to be optimize with the aim to increase comfort and reduce pain. Nowadays, the modeling of this part is completely manual and based on prosthetist skills. The key parameter determining if the socket is properly designed is the pressure distribution in the interface between the skin of residual limb and the internal surface of the socket. In this paper, we expose a method to measure this pressure thought resistive pressure sensors and we illustrate a case study of a transfemoral amputee patient. A visualization tool has been developed to dynamically show pressure data on the 3D model of the residual limb during topic moments of the gait by a color scale. Achieved results and future work will be discussed in the paper.
