Research on the gait of people with partial foot amputation suggests that effective foot length can be restored if the prosthesis has a stiff forefoot, has an above-ankle anterior shell, and restricts dorsiflexion. By independently manipulating these design features of the prosthesis in two participants with partial foot amputation, we showed (using three-dimensional motion analysis) that the prosthesis must include each of these design features to restore effective foot length. When these design features were used at the same time, the participants' gait pattern was more like that of people without limb loss.
