Abstract:
The purpose of this study was to evaluate the change in three-dimensional (3D) ankle joint kinematics on the arch pad. Ten male subjects performed running trials on treadmill, and ten motion capture system were used to record a position data of the reflected markers on the lower limb. Two conditions (no support and support: arch pad) were compared with the joint angles which were analyzed by the Cardan method. As a result, ankle joint eversion angles with support shoe (-6.5degrees+/-2.5degrees) were significantly lower than that with no support shoe (-10.2degrees+/-3.2degrees) (p<0.01). Nevertheless, differences in ankle joint dorsiflexion and abduction angles were not significantly different between support (20.1degrees+/-3.1degrees, -2.5degrees+/-1.9degrees) and no support shoe (20.4degrees+/-3.4degrees, -2.4degrees+/-2.1degrees) (p>0.25, p>0.11). Shoes with medial arch support or using special shoe inserts may help correct one's running form by reducing pronation and may reduce risk of running injury.
