Abstract
High plantar pressures is one of the major causes for the plantar ulceration of diabetic patients. In clinical practice, total contact insoles are routinely used to reduce the risk of ulcerations and the efficacy is quite satisfactory. However there is little scientific evidence to support the efficacy of such orthosis. The purpose of this study was to examine the plantar pressure in the interface between foot plantar and different total contact insoles by using a quasi-static three dimensional finite element model. Also the EMED-Pedar system was used to measure the plantar pressure distribution and the results were compared with finite element results for the verification of the analysis model. In addition, based on different material characteristic, finite element models of three different material combinations of total contact insoles were created and the contact stress analyses were performed. Result showed that with material combination of medium Plastazote, Microcelpuff and Neoprene crepe soling performed best in reducing plantar pressures.
