Design and testing of a flexible leg for a below-knee prosthesis

Abstract

A flexible prosthetic leg was designed and manufactured under Based on SOLIDWORKS knee using software For the dimensions of the human body. Anthropometric data The design was tested using ANSYS Workbench. To analyze stress and stiffness based on the effect of weight and compare it to other designs. The leg was manufactured locally at a low cost and underwent practical testing, including The crawler's weight (VO2max) was checked.To confirm the leg's structural integrity, the results showed improved patient performance with a 5.5% and 12.4% reduction in fatigue during walking at varying speeds with the flexible leg. These findings confirm that walking with a flexible leg is closer to natural walking at a lower cost, allowing access to benefits typically only available with advanced and expensive prosthetics.
