| 摘 要： | 为了探讨人体上肢运动功能康复评定方法,本文研究了健康人抓取过程中的运动协调模式。实验检测了8名健康受试者在不同条件下抓取水杯喝水动作时手臂运动轨迹和主要控制肌群的肌电信号,并且与理论计算结果进行了比较分析,探讨了抓取运动的协调规律。结果表明抓取动作具有运动轨迹的拓扑不变性,关节角度之间存在线性协同变化关系,多块肌群结成运动协调元实现抓取运动的控制。

| Abstract: | In order to discuss the evaluation method of human upper limb movements, the patterns of movement coordination during healthy people prehension have been researched. Eight subjects were asked to perform different reaching-grasping and drinking water from the cup tasks with different indices of difficulty, and the arm movement trajectories and the main muscles group electromyography (EMG) data were collected. To explore the prehension control mechanism, a comparison has been made between the solution of the theoretic calculation and the experimental data. The results show that the topological invariance was observed in the trajectories of different task performance, and the linear relationships between joints covariation were exhibited. Moreover, the different muscles were controlled and combined into units of synergistic muscular group necessary to reach and grasp the goal. |
