The Effect of Arch Pad on Ankle Kinematics during Running / 대한스포츠의학회지

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) (p0.25, 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.
