Little is known about the functional characteristics of prosthetic feet and their effects on gait. This study examined the effects of prosthetic foot forefoot flexibility on the amount of oxygen needed to walk a given distance (oxygen cost) and the preference for these systems by persons with unilateral transtibial amputations. The flexibility of the forefoot did not significantly affect the oxygen cost during walking on a treadmill at self-selected speeds. However, prosthesis users tended to dislike prosthetic feet with an overly flexible forefoot in favor of those that more closely matched the biological system's flexibility during walking.
