Abstract

CURRENT RESEARCH IN FOOT BIOMECHANICS INCLUDES STUDIES ON PREVENTION OF RECURRENCE OF NEUROPATHIC FOOT ULCERS. THIS PRESCRIBES ACCOMMODATIVE INSOLES, WHICH REDUCE PLANTAR PRESSURE LEVELS PARTICULARLY UNDER THE HALLUX. THERE IS LITTLE QUANTITATIVE INFORMATION AVAILABLE REGARDING THE EFFECTS OF INSOLE MATERIALS. THE INSOLE MODELS AVAILABLE IN THE LITERATURE ARE MOSTLY TWO- DIMENSIONAL (2-D). HENCE, THERE IS A NEED TO DEVELOP A 3-D MODEL WITH ACTUAL GEOMETRY WHICH INCLUDES SUFFICIENT DETAILS. IN THIS STUDY A THREE-DIMENSIONAL (3-D) MODEL OF THE INSOLE WAS CONSTRUCTED. A LINEAR AND NON-LINEAR STATIC ANALYSIS USING FINITE ELEMENT METHOD (FEM) WAS DONE. RESULTS WERE COMPARED FOR DIFFERENT MATERIALS SUCH AS SILICON GEL, PLASTOZOT, POLYFOAM, AND ETHINIL VINYL ACETATE (EVA). TO CONSTRUCT OUR 3-D FINITE ELEMENT MODEL 14736 NODES AND 16170 ELEMENTS WERE USED. THIS RESEARCH HAS SHOWN THAT MOST OF THESE MATERIALS ARE VERY EFFECTIVE IN TERMS OF REDUCTION OF STRESS CONCENTRATIONS. THE TECHNIQUES USED IN THIS RESEARCH PROVIDE A PROMISING APPROACH TO UNDERSTAND THE BEHAVIOR OF INSOLE MATERIALS AND PROVIDES A DESIGN GUIDELINE IN THE DESIGN OF THERAPEUTIC FOOTWEAR AND ORTHOSES FOR INSENSATE FEET.
