Development of the methodology of computer aided designing of tailor-made ortheses of the tarsal joint

Abstract eng:
This work aimed to develop the methodology of the selection of ortheses using computer aided engineering tools. Within the framework of this research an orthesis model was formulated by means of reverse engineering. Modification of the model was done by cutting the material with a tool in the shape of an ellipse. Next, a multi-variant numerical analysis was conducted, where the geometry and location of the tool were adopted as parameters. Boundary conditions for a static analysis and fatigue analysis were chosen on the basis of gait tests conducted by means of the BTS Smart - a system for a three-dimensional motion analysis. On the basis of the conducted numerical analyses, the most desirable shape of the orthesis was obtained taking into account the orthesis's real lifetime and comfort of use.
