Design, Construction, and Implementation of a Transtibial Prosthesis Integrating Three Degrees of Freedom Mobility at the Ankle Level

This project focuses on the design, construction, and implementation of a transtibial prosthesis to address the functional and comfort limitations experienced by individuals with lower limb amputations, a condition exacerbated by pathologies like diabetes. The primary goal is to improve patient quality of life, considering that transtibial amputations account for nearly half of all lower limb amputations globally. The methodology involves an exhaustive literature review and a critical analysis of existing prostheses on the market, including their control systems (pneumatic, hydraulic), socket types (PTB, TSB, HST), and materials (titanium, silicone, Kevlar). The innovation specifically targets the foot sole design, the ankle mechanism (incorporating three degrees of freedom), cushioning, and the socket. Evaluation will include computerized gait analysis of the patient using the current prosthesis to identify deficiencies, followed by a redesign assisted by numerical simulation using finite element software. Finally, the prototype will be implemented and tested on the patient for a minimum of 30 days, incorporating electronic enhancements to optimize efficiency before final delivery.<br/><br/><b>Goal</b>: <br/>To design, construct, and implement an advanced transtibial prosthesis aimed at significantly improving the gait and comfort of amputee patients, focusing on the device's efficiency, aesthetics, and ergonomics.<br/><br/><b>Research lines</b>: <br/>Orthotics and prosthetics
