Effects of Shoe Heel Height on the Roll-Over Shapes of Prosthetic Ankle-Foot Systems: Implications for Heel-Height-Adjustable Components

In Brief When wearing shoes of different heel heights, able-bodied persons alter their ankle flexion in a way that keeps their ankle-foot roll-over shapes (i.e., their effective rockers) similarly oriented (parallel) in the shank-reference frame. The purpose of this study was to examine the effects of shoe heel height on the roll-over shapes of prosthetic ankle-foot systems. The hypothesis was that the orientation of the roll-over shapes of...
