Finite Element Model Construction And Design Of Pressure-Reducing Physiotherapy Socks For Diabetic Foot

As a disease that is continuously growing worldwide,diabetic foot poses a serious threat to the health of diabetic patients.Diabetes can lead to many complications,and diabetic foot is one of the most serious.Diabetic foot ulcers are related to factors such as abnormal concentration and distribution of pressure and shear stress on the feet of patients.Existing preventive measures,such as foot ulcer risk assessment,regular checkups,and the use of professional footwear and accessories,can reduce the amputation rate of diabetic foot by more than 50%.This article studies the effects of pressure-relieving therapy socks on the distribution of plantar pressure based on the pathological characteristics of type 2 diabetic foot patients.Finite element models,plantar pressure tests,and peak foot stress data are used to verify the effectiveness of pressure-relieving therapy socks.To achieve this goal,a computer-based foot model was simulated and created using a reverse engineering method based on data obtained from CT and MRI scans.After mesh optimization processing,finite element analysis was performed to analyze the foot pressure distribution when wearing pressure-relieving therapy socks for type 2 diabetic foot.Ecoflex gel was chosen as the main material for pressure-relieving therapy socks,and factors such as sock length,tightness,material,and stitching were considered in the design of the half-wrapped pressure-relieving therapy socks to reduce foot pressure.Compared to pressure-relieving products on the market,the half-wrapped design of pressure-relieving therapy socks focuses on the high-stress areas of the entire foot and the toes,providing a more cost-effective,effective,and easy-to-use product for foot pressure relief.In the experiment,Tactilus multi-point thin film pressure sensor system and Tekscan insole pressure testing system were used to verify the effect.The NRS and VAS evaluation scales were used to evaluate the effect of pressurerelieving therapy socks for subsequent improvement optimization and data analysis.This research topic still needs to establish a more comprehensive and updated foot database to explore better design principles and pressure-relieving effects.Longer-term use tracking and efficacy evaluation of the product is also required for more objective evaluation.Considering the significant differences in the feet of different diabetic patients,more standard schemes need to be provided to better serve diabetic foot patients.Furthermore,further research on the pathogenesis and treatment of diabetic foot is needed to explore the design and optimization of pressure-relieving therapy socks,integrating biocompatible materials and artificial intelligence technologies to develop more intelligent and personalized pressurerelieving products.
