Some functions of walking are adversely affected in prosthesis users because of reduced or absent ankle motion. However, combining a prosthetic ankle unit with a particular prosthetic foot could have unanticipated consequences. This study investigated the effect of prosthetic ankle units on the gait of persons with bilateral transtibial amputations. Subjects were tested while walking with and without Endolite Multiflex Ankles. The ankle units were found to increase ankle motion, but the foot-ankle rocker radius was decreased, which could adversely affect gait. Therefore, prosthetists need to carefully consider the effect of combining different prosthetic components on overall walking function.
