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

我们使用“手指延伸”和“手指延伸”的短语，考虑到它们处于同一描述水平。然而，我们的大脑可能无法平等地处理这些动作。本研究的结果表明，手指屈曲和前臂旋前被认为是更显着的。此外，当循环地移动两个关节时，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.
