The purpose of this study was to describe a rolling motion, which is common in normal adults and patients with motor disorder, and to try to understand the mechanism of the motion. Ten healthy young adults participated in the experiment and were requested to roll from supine to side-lying by pressing the floor with their contra-lateral foot. Their motions in the task were measured with a 3-D analysis system and a force platform. The hip abduction-adduction angle was at around the neutral position and was approximately constant throughout the rolling motion. The hip rotation angle was at a neutral or slightly internally rotated position at the beginning of the motion, and it externally rotated linearly toward the end of the rolling motion. These patterns were thought to be mechanically the most effective for the subjects to perform the motion as was also indicated by the kinetic analysis.
本研究的目的是描述一种在正常成年人和运动障碍患者中常见的滚动运动，并试图理解该运动的机制。十名健康的年轻成年人参与了实验，他们被要求用对侧脚压地，从仰卧位滚动到侧卧位。使用三维分析系统和测力平台测量他们在该任务中的动作。髋关节外展-内收角度处于中立位置左右，并且在整个滚动运动过程中大致保持恒定。髋关节旋转角度在运动开始时处于中立或略内旋位置，并且在滚动运动接近结束时线性地向外旋转。动力学分析也表明，这些模式在机械上对受试者执行该运动最为有效。
