Gait Change Using an Ankle-Foot Orthosis with an Oil Damper in a Stroke Patient with Hyperextension of the Knee Joint in Late Stance

Yamamoto S, Katsuhira J and Miura N

The gait of a stroke patient who showed hyperextension of the knee joint in late stance was measured and compared with and without an ankle-foot orthosis. When the patient walked using an ankle-foot orthosis with an oil damper that assisted the heel rocker, the center of pressure was kept at the heel in loading response and the start of the plantarflexion moment was delayed. Forward inclination of the shank in early midstance was obtained, and the hyperextension of the knee joint in late midstance was reduced. The orthosis was able to control the shank inclination, and the shank vertical angle was found to be an important parameter for understanding the gait of stroke patients with and without ankle-foot orthoses.
