本研究的目的是描述正常成人和运动障碍患者中常见的滚动运动，并试图了解该运动的机制。十名健康的年轻人参加了实验，并被要求用对侧脚压地板从仰卧翻身为侧卧。他们在任务中的动作是通过 3D 分析系统和力平台测量的。髋部外展-内收角位于中立位置附近，并且在整个滚动运动过程中近似恒定。髋部旋转角度在运动开始时处于中立或轻微内旋位置，并且在滚动运动结束时呈线性外旋。正如动力学分析所表明的那样，这些模式被认为在机械上对于受试者执行运动来说是最有效的。
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.
