Study Summary

Typically people need separate prosthetic feet for running and walking. To bridge the gap, this study will test the Compliant Adaptive Energy Storage and Return (CAESAR) foot. This foot can change from a walk mode to a run mode with the push of a button. The investigators will test and improve this foot design mechanically, and then test this design on individuals with lower limb amputation in a lab setting. The goal of this project is to develop a passive prosthetic foot that can serve two purposes in someone's daily life: walking and running, to allow them to be more active.

Primary Outcome

Participants will walk over sensors that measure the force under their foot. Peak ground reaction force in the anterior direction is measured in Newtons and then divided by the individual's body weight (BW). The resultant force is measured in Body-weights.
