Customization designs and biomechanical analysis of transtibial prosthetic leg

A prosthesis is a technical mechanism that is designed as a substitution of the function of a missing limb or body part. This device has been effectively used as an essential tool for amputees. Therefore, the main purpose of this study is to biomechanically evaluate and optimize the prosthetic'...
