Invariant positions on a phase plane of joint angular position and velocity have been proposed as a means by which interlimb coordination may be achieved. This note identifies a problem in the testing, using conventional statistics, of hypotheses derived using the phase plane model. A possible solution is proposed based on directional statistics. Conclusions regarding phase angle invariance, which are based on conventional statistics, must be viewed with some caution.
关节角位置和速度相平面上的不变位置已被提出作为实现肢体间协调的一种方式。本注释指出了在使用传统统计方法检验基于相平面模型得出的假设时存在的一个问题。基于方向统计提出了一种可能的解决方案。基于传统统计得出的关于相角不变性的结论必须谨慎看待。
