When sampling electromyograms (EMGs) with one pair of electrodes, it seems implicitly assumed the detected signal reflects the net muscle excitation. However, this assumption is discredited by observations of local muscle excitation. Therefore, we hypothesize that the accurate assessment of muscle excitation requires multiple EMG detection and consideration of electrode-fiber alignment. We advise prudence when drawing inferences from individually collected EMGs.
当使用一对电极采集肌电图 (EMG) 时，似乎隐含地假设检测到的信号反映了肌肉的净兴奋。然而，这种假设被局部肌肉兴奋的观察结果所否定。因此，我们假设准确评估肌肉兴奋需要进行多次 EMG 检测并考虑电极-纤维排列。我们建议在从单独采集的 EMG 中得出推论时要谨慎。
