| Research Abstract |
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.
