过去对双手协调的研究表明,人们普遍倾向于以对称方式移动四肢,也称为同相模式。其对应的非对称或反相模式的精度和稳定性较低。这种激活同源肌肉群的普遍趋势被称为肌肉分组约束(自我中心约束)。本研究证实了这种约束在水平面上执行的各种协调模式中的普遍性。此外,有证据表明外部空间中的运动方向也会限制双手协调(非中心约束)。总的来说,目前的观察表明方向是一个重要的运动参数,它在中枢神经系统中编码,并且受到双肢神经规范之间相互作用的影响。
Past studies on bimanual coordination have revealed a general preference to move the limbs in a symmetrical fashion, also denoted as the in-phase mode. Its counterpart, the asymmetrical or anti-phase mode, is performed with lower degrees of accuracy and stability. This ubiquitous tendency to activate the homologous muscle groups is referred to as the muscle grouping constraint (egocentric constraint). The present study confirmed the generalizability of this constraint across various coordination patterns, performed in the horizontal plane. In addition, evidence was generated that movement direction in extrinsic space also constrains bimanual coordination (allocentric constraint). Overall, the present observations suggest that direction is an important movement parameter that is encoded in the central nervous system and that is subject to interactions between the neural specifications of both limbs.
