摘要

人类上肢的运动是一种自然行为,需要多块肌肉在空间和时间上的协调。在人体运动控制中,神经策略是如何控制上肢运动的。这些上肢运动包括外展、内收、肩屈和肩伸。根据我们的研究,我们提出了一个假设,即不同主体之间的一些肌肉协同作用可能具有相似的特性。为了验证这一假设,我们收集并分析了6名健康受试者的肌电图数据。需要九块肌肉来重现每个受试者的运动。我们使用非负因子分解方法来识别任务期间的肌肉协同作用,并检查这种协同作用对自然行为的功能意义。通过这一发现,可以清楚地解释这些运动中上肢的神经肌肉控制策略,也可能为支持肌肉协同假说提供重要证据,并为康复提供依据。

Muscle Synergy Analysis on Upper Limb Movements of Human Arms
Upper limb movements of human arms are natural behaviors which require both the spatial and temporal coordination of multiple muscles. We now investigate how the neural strategy control upper limb movements in the human movement control. These upper limb movements include abduction, adduction, shoulder flexion and shoulder extension. According to our research, we make a hypothesis that a few muscle synergies across different subjects may have similar properties. To validate this hypothesis, we collected and analyzed EMG data in six healthy subjects. Nine muscles were required to reproduce the movement of each subjects. We used a nonnegative factorization approaches to identify muscle synergies during the tasks and to examine the functional significance of such synergies for natural behaviors. Through this finding, the neuromuscular control strategies of upper limb in these movements could be explained clearly, which may also provide significant evidence to support the hypothesis of muscle synergies and a basis for rehabilitation.
