To provide reference values for the isolated motor unit potentials (MUPs) in the external anal sphincter (EAS) muscle, as mean duration, mean amplitude, mean area, number of turns and number of phases, related to the age of the patient. These data are not available in worldwide literature in spite of the fact that the EAS muscle is being increasingly mentioned in relation to differential diagnosis.
Study of 235 subjects aged 0-80 years using an automated analysis program.
The study performed shows a clear gradual progression of the mean duration with patient age. The variability of all other parameters tested is also analyzed.
Our study shows that the classical values of MUPs isolated in the EAS muscle are directly related to age, and that this method is fully reliable to study its pathological conditions.
提供与患者年龄相关的肛门外括约肌(EAS)肌肉中孤立运动单位电位(MUP)的参考值,包括平均时限、平均波幅、平均面积、转折数和相数。尽管在鉴别诊断中越来越多地提及EAS肌肉,但全球文献中尚无这些数据。
使用自动分析程序对235名年龄在0至80岁的受试者进行研究。
所进行的研究显示平均时限随患者年龄呈明显的逐渐进展。还分析了所有其他测试参数的变异性。
我们的研究表明,EAS肌肉中孤立MUP的经典值与年龄直接相关,并且该方法在研究其病理状况时完全可靠。
