Comparison of carbon fiber and glass fiber partial foot orthosis by Experimental and computational method

Abstract

Many persons living in industrialized nations who have undergone lower limb amputations now have better function and a higher quality of life because of significant prosthetic foot research and development advancements over the past 20 years. A drawback of this new R&D is that the vast majority of end users in developing nations cannot use it because of the components' high price, low durability, high maintenance requirements, and limited accessibility. Research is needed in this area to build and improve a prosthetic foot that is extremely valuable, meets economic, environmental, and physical standards, and can withstand harsh working environments and climates. A successful prosthesis that strives to maximize function while minimizing production costs typically relies on the elasticity of its component materials to produce a “spring,” which resembles a physiological foot's stride. To identify design elements influencing improved functional results, this study examined the mechanical parameters of PFOs, specifically structural stiffness, rotational motion, and strut deflection. Diabetes patients frequently receive prescriptions for insoles and footwear to help avoid the development of foot ulcers. Plantar peak pressure (PPP) is decreased in areas of interest using insoles and sturdy footwear (ROI). These areas are known as the heel and metatarsal phalangeal joints 1–2. While previous research has looked at the effectiveness of individual materials in partial foot orthoses, this study provides a direct comparison of carbon fiber and glass fiber materials. By using both experimental and computational methods, the study is able to provide a comprehensive assessment of the performance of these materials in partial foot orthoses.This study is designed to compare the pressure distribution of two different kinds of insoles.
