Community Walking Trials: Investigational Prosthetic Foot

Community Walking Trials: Investigational Prosthetic Foot

The research team has developed a prosthetic foot that is designed to be adaptable on uneven
ground and side-slopes as well as for uncertain placement of foot on the ground. The
investigational foot may also help to reduce forces acting through the prosthesis
socket. The purpose of this study is to compare a participant’s usual prosthetic foot with the new prosthetic foot during usual daily activities. The study hopes to understand if participant’s experience any differences between different foot prostheses.
