Insole Optimization for Rheumatoid Arthritis Patients

Summary

Rheumatoid arthritis affects 0.5% of the population, often leading to foot deformities and pain that are difficult to treat. Management is based on controlling inflammation, adapting footwear and using custom-made insoles, all of which have proven effective. The aim of this research is to build a digital model of plantar pressures based on CT scans, in order to optimize orthopedic insoles. The study will analyze the gait of patients with and without standard insoles to identify mechanical criteria correlated with pain. The ultimate aim is to design optimized insoles, validated by a new gait analysis.
