Development of an easy and effective attachment system for lower limb prosthesis

Abstract

This study aimed to introduce a new suspension system that is capable of increasing the amputee’s satisfaction in terms of locking the residual limb inside the prosthetic socket. This paper describes the design and development phases carried out to optimize the final solution. The design system was based on the amputee’s needs and the requirements of prosthetic suspension systems. The final solution is a combination of a guiding and fixation system, to overcome some of the reported problems with the current systems, presenting a new simple suspension method that improves the donning and doffing of prosthesis. The new suspension system is a good alternative system to improve the life quality of amputees with lower activity level on the daily basis and, consequently, ease their rehabilitation.
