Abstract

Knowledge of using the Ankle foot Orthosis in patients with severe developmental dysplasia of the hip is crucial and may help to improve the gait cycle during walking. This paper aimed to evaluate and study the kinematics and kinetics of the hip joint during walking in the sagittal plane for a patient with severe hip dislocation age 26 ( the author of this paper) who is experiencing using two different types of ankle-foot Orthosis (Custom-made, and Leaf-AFO). The data were collected using ten cameras and one force plate. We used an inverse dynamic approach to calculate sagittal joint angles, moments and power. The results pointed out that The Custom-Orthosis had a higher moment during the late stance of the gait cycle than that of Barefoot; the data showed significant change by a mean difference of 0.1604 Nm/kg. However, the Leaf AFO Spring Orthosis did not change much the flexion moment during the late stance phase. The paper concluded that both orthosis wearing the custom –made AFO improved the kinetics of the hip joint in special while wearing the custom –made AFO leading to reduce the pain associated with loading during walking.
