Abstract

In this study, the kinematic effect of two molding methods in the manufacture of foot orthoses on ankle joint was examined. The aim of this study was to determine a more beneficial method about ankle kinematics in the manufacture of insoles for people with flexible flat foot. Ten males aged 19 to 27 years, with normal BMI and normal gait pattern participated in this study, all of them had flexible flatfoot. Each person wearing special shoes on three situations: stepped without the insole, with the Slipper cast insole and Circumferential wrap method insole and in each situation completed a walk cycle. The kinematic data were collected and measured for each subject under three assumed positions by VICON motion analysis system. For comparison and analysis of three assumed situation, repeated measures test (ANOVA) was used. The results of this study show that the use of two molding method, had no immediate effect on reducing the average maximum eversion angle of the ankle. Eversion speed limit in the ankle was not affected by insole molding and no significant difference was observed. Compared to the situation without insoles, insole with the Slipper cast and Circumferential wrap molding method led to little difference in amplitude eversion. This study evaluated immediate effect of insoles. Two custom foot orthotics intervention did not lead to significant decreases in maximum eversion angle of ankle in the frontal plane.
