The purpose of the study is to establish the quantification of steadiness in children, and determine its ability. The fluctuations in index finger during movement matching tasks in horizontal plane were measured by multiple high-resolution laser displacement sensors. It was demonstrated that motor skill of index finger is determined by two-dimensional plane not by optimal direction. In addition, fluctuations of index finger in children were larger than those in young adults. These results suggest that poor motor control for children is related to weak stiffness around the joint.

该研究的目的是建立儿童稳定性的量化，并确定其能力。利用多个高分辨率激光位移传感器测量了食指在水平面内运动匹配任务中的波动。结果表明，食指的运动技能是由二维平面决定的，而不是由最佳方向决定的。此外，儿童的食指波动大于青年人。这些结果表明，儿童运动控制不良与关节周围的弱刚度有关。
