Abstract

The relationship between movements and their postural adjustments was studied on the basis of the relation between the displacement of center of pressure (CoP) on grand force platform in the anterior-posterior direction and angular changes in the ankle and hip joints during squat in six healthy individuals. It was shown that during the fxation of the joint angles at the squatting the ankle joint more fexed than the hip joint when the CoP shifted forward, while the back displacement of the CoP resulted in more prominent changing of angular joint at the hip joint than at the ankle joint. A linear relationship between the displacement of CoP and the fexion angles more frequently observed at the ankle joint than at the hip, which may indicate that during squatting at the locked position of the joint angles the fexion of the ankle joint was determined mainly by the biomechanics of the skeleton,while in the hip joint biomechanical factors could largely combined with the central processes controlling posture.

Keywords: biomechanics, lower extremity, joint angles,stabilography.
