The Effects Of Walking Speed On Gait Propulsion When Wearing An Ankle-Foot Orthosis, Alli Kalina

UNO Student Research and Creative Activity Fair

Peripheral artery disease (PAD) is a cardiovascular disease that results from blockage of one or more arteries in the lower extremity. Often, patients with PAD have reduced ability to push off with the foot at the end of the gait cycle. When walking, the ankle contributes the majority of the power to propel the body into the next step. An ankle-foot orthosis (AFO) is a device that aids in ankle propulsion by increasing the energy return, thus decreasing the ankle deficit in pathological individuals. The purpose is to investigate the effect of walking speed on ankle propulsion during walking. Subjects …
