We describe the innervation zone (IZ) location in 43 muscles to provide information for appropriate positioning of bipolar electrodes for clinical and research applications.
The IZ was studied in 40 subjects (20 men and 20 women) using multichannel surface electromyography (sEMG). Signal quality was checked visually to identify motor unit action potentials and estimate muscle fiber conduction velocity.
Results in 33 muscles were classified as excellent or good, because it was possible to identify an area which is favorable for appropriate positioning of an electrode pair without the need to previously determine the IZ location.
Knowledge of IZ location will increase standardization and repeatability of sEMG measures.
我们描述了 43 块肌肉的神经支配区（IZ）位置，为临床和研究应用中双极电极的适当定位提供信息。
使用多通道表面肌电图（sEMG）在 40 名受试者（20 名男性和 20 名女性）中研究了 IZ。通过视觉检查信号质量来识别运动单位动作电位并估计肌肉纤维传导速度。
33 块肌肉的结果被分类为优秀或良好，因为可以识别出一个有利于适当放置电极对的区域，而无需事先确定 IZ 位置。
IZ 位置的知识将提高 sEMG 测量的标准化和可重复性。
