Abstract

<p>The purpose of this study establishes an evaluation of correlation between the gait and the structure of the knee- brace (CB-brace) for K-OA. The optical 3D motion capture analysis system was used for gait analysis. In advance, we confirmed the fit of the knee brace and the ratio of the medial compartment by two measurement methods.One confirmed the ratio of the medial compartment of the knee by measuring the gap between the center of the knee joint and Mikulicz line while another carried out gait analysis without wearing and while wearing knee-brace. The extent of the knee pain of the each subject can be objectively evaluated by referring to the visual analogue scale (VAS) for each trial. We measured the structure characteristic of the knee-brace attached 8makers on arm support during gait. The results showed ① The angle change amount of each arm. ② The distance between the top of each arm and the joint. ③ The posture change of the knee brace by the degree of the rotation angle of the X, Y, Z axis by the orthosis coordinate system. In conclusion, we evaluated the correlation of the knee-orthosis structure during gait.</p>
