In 1997, several types of the micro reflective markers were produced and were tested for motion analysis of fingers, resulting that a roundness and a reflectivity were important for the accuracy. At this time the number and the location of reflective markers were defined. Until the end of this year, the methodology of the finger motion analysis using the VICON and the micro reflective markers was established.In 1998, the pinch motion of eleven normal subjects was analyzed. The pinch motion was performed by the thumb and the index finger and each subject repeated to pinch the three kind of objects, small ball, coin, and small bar, which was used in the vocational test defined by Japanese Government. In each pinch motion, the thumb and the index finger showed constractive pattern in the flexion angle of the DIP, PIP, and MCP joint.In 1999, the motion analysis was performed in the patients with the cubital tunnel syndrome. In this study, the clinical score for ulnar nerve palsy was counted and was compared to the hand motion of normal subjects. In the patients with a distal ulnar nerve palsy, the flexion angle of each finger joint angle (I. E. flexion angle of the DIP, PIP, and MCP joint) was significantly larger than that of normal subjects. This result showed that the palsy hand flexed the finger joints more in order to produced larger strength than the normal.

1997年，生产了几种类型的微反射标记，并测试了手指的运动分析，结果是圆度和反射率对精度很重要。此时，确定了反射标记的数量和位置。直到今年年底，VICON和微反射标记的手指运动分析方法才得以建立。1998年，我们分析了11名正常受试者的手指运动。捏的动作是用拇指和食指，每个受试者重复捏三种物体：小球、硬币和小棒子，这是日本政府规定的职业测试中使用的。1999年对肘管综合征患者进行了运动分析，发现拇指和食指在DIP、PIP、MCP关节屈曲角度上均表现为收缩。在这项研究中，计算了尺神经麻痹的临床评分，并与正常受试者的手运动进行了比较。远端尺神经麻痹患者各指关节屈曲角度(DIP、PIP、MCP关节屈曲角度)均明显大于正常人。这一结果表明，瘫痪的手比正常人更多地弯曲手指关节，以产生更大的力量。
