Abstract
While walking, we often change our direction and speed as necessary. The movement made to change the direction is divided into two types: the spin turn and the step turn. The axis of the lower extremity in the spin turn is on the same side as the direction in which the turn is made, whereas in the step turn, it is on the opposite side. In this study, with respect to the spin turn and step turn, the center of pressure trajectories and the electromyography patterns of the lower extremity were measured. Based on these results, the function of the lower extremity required for the spin turn and step turn is explained and discussed.
