Muscles oscillate with a frequency around 10 Hz. But what happens with myofascial oscillations, if two neuromuscular systems interact? The purpose of this study was to examine this question, initially, on the basis of a case study. Oscillations of the triceps brachii muscles of two subjects were determined through mechanomyography (MMG) during isometric interaction. The MMG-signals were analyzed concerning the interaction of the two subjects with algorithms of nonlinear dynamics. In this case study it could be shown, that the muscles of both neuromuscular systems also oscillate with the known frequency (here 12 Hz) during interaction. Furthermore, both subjects were able to adapt their oscillations against each other. This adjustment induced a significant (α < .05) coherent behavior, which was characterized by a phase shifting of approximately 90°. The authors draw the conclusion, that the complementary neuromuscular partners potentially have the ability of mutual synchronization.
肌肉以约10赫兹的频率振荡。但是，如果两个神经肌肉系统相互作用，肌筋膜振荡会发生什么情况呢？本研究的目的首先是基于一个案例研究来探讨这个问题。在等长相互作用期间，通过肌动图（MMG）测定了两名受试者肱三头肌的振荡情况。利用非线性动力学算法对MMG信号进行了关于两名受试者相互作用的分析。在这个案例研究中可以表明，在相互作用期间，两个神经肌肉系统的肌肉也以已知频率（此处为12赫兹）振荡。此外，两名受试者能够使他们的振荡相互适应。这种调整引发了显著（α < .05）的相干行为，其特征是相位偏移约90°。作者得出结论，互补的神经肌肉伙伴可能具有相互同步的能力。
