Abstract :

This article focuses on the design and analysis of a custom medical insole developed using SolidWorks software for 3D modeling and OpenSim for muscle simulation. The aim of this study is to address and improve the structural and functional weaknesses of individuals' feet by conducting a detailed analysis of foot pressure distribution and optimizing the design of personalized insoles accordingly. The process involved gathering data from 3D foot scans and pressure measurements to ensure the precise fit and effectiveness of the insoles. Results from the pressure tests demonstrate that these custom insoles significantly enhance pressure distribution across the foot and improve the performance of leg muscles during movement. Furthermore, this research highlights the potential of custom-made insoles as a valuable solution for correcting structural foot abnormalities, improving balance, and reducing pain caused by gait-related issues. The findings suggest that personalized insoles can be a highly effective therapeutic tool for addressing common foot problems and enhancing overall mobility in patients.
