Description

[Purpose] The purpose of this study was to show the influence of calcaneal eversion on the trunk angle, pelvic alignment, lower extremity angle, and center of gravity (COG) while quietly standing in three dimensions. [Methods] Twelve young healthy subjects participated in the study. Subjects were requested to remain in a quiet standing position in four different modes: feet flat on the floor and on wedges angled at 5°, 10°and 15° designed to induce calcaneal eversion. Sequencing was randomly captured by a three-dimensional motion analysis system and force platforms. [Results] A significant increase was found in calcaneal eversion, calcaneal anteversion and ankle dorsiflexion. This result was based on the kinematic link. COG was shifted forward, which corresponds with the increase in the slope’s angle. [Conclusions] Hip and pelvis function played an increasingly important role as the angle of wedges increased.
