运动控制的一个长期目标是确定中枢神经系统控制的基本输出:中枢神经系统是控制单个运动单元、单个肌肉、肌肉群、运动的运动学或动力学特征的激活,还是仅仅关心完成一项任务?当然,由CNS控制的输出可能不是排他性的,而是可以并行或分层控制多个输出。在这篇综述中,我们研究了一个特定的假设控制水平:中枢神经系统通过肌肉群的灵活组合或肌肉协同作用产生运动。最近的几项研究检验了这一假设,提供了支持和反对这一假设的证据。我们讨论这些结果和肌肉协同假说的现状。
A long standing goal in motor control is to determine the fundamental output controlled by the CNS: does the CNS control the activation of individual motor units, individual muscles, groups of muscles, kinematic or dynamic features of movement, or does it simply care about accomplishing a task? Of course, the output controlled by the CNS might not be exclusive but instead multiple outputs might be controlled in parallel or hierarchically. In this review we examine one particular hypothesized level of control: that the CNS produces movement through the flexible combination of groups of muscles, or muscle synergies. Several recent studies have examined this hypothesis, providing evidence both in support and in opposition to it. We discuss these results and the current state of the muscle synergy hypothesis.
