Abstract

Legg-Calve-Perthes Disease is a disorder involving the closure of the blood supply of the femoral head, resulting in the hip bone turning black. The deformity of femoral head occurs as a result of hip joint irritability and this depends on the severity of the disease. Treatment methods for Perthes disease are divided into operative and non-operative fields, where in the non-operative field different orthosis are prescribed. These orthosis are designed based on the idea of reducing the stress applied on the hip joint; the most famous one called Scottish Rite orthosis. To facilitate study of effect of different orthosis and their design parameters on the forces applied to the hip joint, a mathematical model of such patients during walking would be useful. The prerequisite of such model is the knowledge of gait performance of the patients using it and also the perception of the effects this orthosis has on the walking pattern of these patients. To this end, an analysis of the gait performance is given here. This analysis will then be useful in a path planning procedure. For the analysis to take place a Gait Analyzing System that uses QTM software to capture motions and also a Visual 3D software is used. © 2014 IEEE.
