摘要: The diabetic foot is one of the most serious complications diabetes mellitus and it can lead to ulcerations amputations. Finite element analysis quantifies loads developed in different anatomical structures describes how these affect tissue during foot–floor interaction. This approach for subjects' could provide valuable information process plantar orthosis fabrication fit. purpose this study was develop two finite models hindfoot, healthy neuropathic subjects. These accounts vivo kinematics, kinetics, pressure (PP) data magnetic resonance images. were acquired gait on 10 neuropathics Validity has been assessed through comparison between peak PPs simulated experimental data: root mean square error (RMSE) percentage value evaluated. Two elements performed: subject-specific simulations terms both geometry analysis, by adopting complete dataset as boundary conditions. Model predicted pressures good agreement with those experimentally measured. Best obtained case (RMSE 13%).
