Abstract

[Purpose] The purpose of this study was to reveal the characteristics of dynamic postural adjustments in rats using a posturography technique. [Subjects] Five adult rats. [Methods] We measured changes of center of pressure (COP) during floor inclination in the lateral (left) side and anteroposterior directions at angles from 0 to 30 degrees using different angular velocities ranging from 1.8 to 15 degree/sec. [Results] Animals maintained a standing posture at all inclination angles in all directions, and exhibited COP changes along with increase of the inclination angle. Animals showed dynamic postural adjustments together with characteristic COP changes in lateral side direction at angular velocities from 1.8 to 10 degree/sec. In anteroposterior directions, however, animals showed COP changes without dynamic postural adjustments in accordance with the increase of floor inclination. [Conclusion] These results suggest that animals correct posture in response to lateral disturbances using dynamic postural adjustments, and that animals stabilize posture without dynamic postural adjustments in anteroposterior disturbances. <br>
