摘要

痙攣狀態嚴重程度的測定，在臨床應用上仍多以主觀的半定量方式為之。本研究的目的乃希望對於中風後有上肢痙攣的病人，能夠定出一個客觀而定量的模式，進行痙攣嚴重程度的定量評估。運用Kin-Com等速運動機，針對16位有不等痙攣程度的中風病人，分別以每秒5度到每秒210度的8種速度，在完全放鬆且不受重力影響的姿勢下，拉動受測者的肘關節，並計錄其抗力曲線，經過比較之後，發現在每秒150度的速度下，是測量肌肉痙攣狀態的最佳速度。對於肘屈肌而言，最後40度的平均抗力值是最佳的參數；對於肘伸肌而言，最後50度抗力曲線的斜率則最佳。

Subjective semi-quantitative method is often used to evaluate the severity of spasticity in clinical condition. The purpose of this study is to develope an objective and quantitative model to evaluate the severity of spasticity for hemiplegic patients. We utilize Kin-Corn III isokinetic machine to evaluate 16 hemiplegic patients with 8 velocities from 5 to 210 degrees per second. The elbow joints of subjects are pulled when subjects totally relaxed and under no influence of gravity. The curve of resistance force was recorded and analyzed. We found 150 degrees per second is the best velocity for the evluation. And for elbow flexor, the average force of the last 40 degrees is the best parameter; and the slpoe of curve of last 50 degrees is the best one for elbow extensor.
