INTRODUCTION
This study aimed to obtain normal MUAP values in 2 facial muscles and to compare the results of different analysis methods.
METHODS
The frontalis muscle of 36 and the mentalis muscle of 28 normal subjects were examined, and mean and outlier values of all MUAP parameters were calculated with the automatic method. Next, manual editing of the recorded raw data provided new sets of values for comparison.
RESULTS
The frontalis muscle MUAPs have significantly shorter duration, smaller amplitude and a lower number of turns and phases compared with those of mentalis. Higher MUAP duration values in the frontalis were the only significant difference after the comparison of the different analysis methods.
CONCLUSIONS
The set of normal values for frontalis and mentalis in this study could be useful in routine practice. Careful manual editing of the frontalis MUAPs is recommended for more accurate determination of their duration.
简介
本研究旨在获得 2 块面部肌肉的正常 MUAP 值，并比较不同分析方法的结果。
方法
对 36 名受试者的额肌和 28 名受试者的颏肌进行检查，使用自动方法计算所有 MUAP 参数的均值和异常值。然后，对记录的原始数据进行手动编辑，提供新的数据集进行比较。
结果
与颏肌 MUAP 相比，额肌 MUAP 的持续时间更短、幅度更小、匝数和相位更少。在不同分析方法的比较中，额肌 MUAP 持续时间值更高是唯一的显著差异。
结论
本研究中额肌和颏肌的正常值集可在常规实践中使用。建议对手部 MUAP 进行仔细的手动编辑，以更准确地确定其持续时间。
