Timing of salient phases of joint movements affect multi-limb coordination

我们使用“手指延伸”和“手指延伸”这两个短语是考虑到它们在同一层次上的描述。然而，我们的大脑可能不会平等地处理这些动作。本研究结果表明，手指屈曲和前臂旋前被认为是更显著的。此外，当两个关节循环运动时，关节运动中的显著相位往往同时发生。

We use the phrases of “finger extension” and “finger extension” with considering that they are on the same level of description. However, our brain may not handle those movements equally. The results of the present study showed that finger flexion and forearm pronation were considered to be more salient. In addition, when moving two joints cyclically, the salient phase in joint movements tend to occur coincidentally.
