Abstract

[Purpose] This study aimed to clarify the relationship between the trajectory of center of pressure (COP) during gait and mobility of the subtalar joint (STJ). [Subjects and Methods] The subjects were ten healthy adults. The trajectory of the COP during gait was measured by a foot pressure distribution measuring system. The positions of COP in the rearfoot, midfoot and forefoot were calculated from the COP trajectory and examined to estimate the correlation with measured physical parameters of STJ. [Results] The COP traced a trajectory that passed from rearfoot to midfoot slightly on the outer side of the foot, and moved inward in the forefoot. In addition, the outward trajectory of COP in the rearfoot and forefoot might be related to the small pronation mobility of STJ. [Conclusion] The results of this study suggest that the habitual activities of supination muscles of STJ lead to a shift in the COP trajectory to the outside and a reduction of pronation mobility of STJ.
