OBJECTIVE
The aim of these modeling studies on the generation of motor unit potentials (MUPs) was to establish the influence of MU parameters and recording conditions on the shape irregularity of MUPs. The focus was on the dependence of the irregularity of MUPs on fiber density, fiber diameters and the recording distance from the end-plate zone.
METHODS
The study was performed using the 'EMG Simulator' software for modeling of MUP and our own software for calculations.
RESULTS
The results indicate that the irregularity of a MUP increases with increased recording distance from the end-plate zone and decreases with increased fiber diameter and/or with increased fiber density. The quantitative relationship between these factors has been derived.
CONCLUSIONS
The relationships determine the structural conditions in which irregular potential may be generated and therefore may be helpful in the interpretation of atypical MUPs.
目的
这些关于运动单位电位（MUP）产生的建模研究旨在确定运动单位（MU）参数和记录条件对MUP形状不规则性的影响。重点在于MUP不规则性对纤维密度、纤维直径以及距终板区记录距离的依赖性。
方法
本研究使用“肌电图模拟器”软件进行MUP建模，并使用我们自己的软件进行计算。
结果
结果表明，MUP的不规则性随着距终板区记录距离的增加而增加，随着纤维直径的增加和/或纤维密度的增加而减小。已得出这些因素之间的定量关系。
结论
这些关系确定了可能产生不规则电位的结构条件，因此可能有助于解释非典型MUP。
