" STRAIN CLUSTERS " ANALYSIS TO CHARACTERIZE THE RISK OF PRESSURE ULCER: APPLICATION TO HEEL ULCERS

Résumé

Foot pressure ulcers (PU) mainly result from excessive pressure intensity (internal strains above 50% for about 10 minutes) or prolonged compression (internal strains above 20% for about two hours). It is therefore crucial to monitor the internal strains using biomechanical models combined with skin surface pressure measurements to improve daily examination. A biomechanical Finite Element foot model was elaborated to analyze the internal strains. A new criterion, defined as “cluster volume”, was introduced by considering the volume of the largest group of adjacent nodes exhibiting a Von Mises (VM) strain over the 20 and 50% thresholds.
