概要:

Two- and three-dimensional motion analysis methods are commonly used for the measurement of dynamic lower limb alignment. However, there has been very few comparative studies between these two methods. The purpose of the present study was to investigate the correlation of the biomechanical data between two- and three-dimensional motion analysis methods for the evaluation of dynamic knee alignment. Seven female and 7 male college asketball players were recruited to … perform a drop jump test. The Knee/Hip ratio for evaluation of valgus alignment of the knee in the coronal plane was measured by a two-dimensional motion analysis system with a digital video camera. The joint kinematics and kinetics of the knee were evaluated by a three-dimensional motion analysis system. From toe touch to maximum knee flexion, the knee/hip ratio decreased significantly both in males and females. However, the knee valgus angle and the peak knee valgus moment were not correlated with change in the knee/hip ratio. Both males and females showed a similar change in the knee/hip ratio in the two-dimensional motion analysis during the drop jump, but signifi cant diff erences in joint kinematic and kinetic patterns were seen in the three-dimensional motion analysis. These diff erences should be taken into account when using the two diff erent motion analysis systems. 続きを見る
