Effects of Custom-Made Insole Materials on Frictional Stress and Contact Pressure in Diabetic Foot with Neuropathy: Results from a Finite Element Analysis

Offloading plantar pressure in a diabetic foot with neuropathy is challenging conventional clinical practice. Custom-made insole (CMI) materials play an important role reduction, but the assessment costly and time-consuming. Finite element analysis (FEA) can provide efficient evaluation of different insoles on distribution. This study investigated effect CMI their combinations reduction for using FEA. The was conducted by constructing three-dimensional model along to peak contact between CMI. softer material (E = 5 MPa) resulted better compared stiffer 11 MPa). well redistributed its combination. In addition, single reduced frictional stress under first metatarsal head combination materials. have beneficial redistribution neuropathy. provided effective approach selection
