## Abstract During multi‐motor unit action potential (MUAP) analysis of the tonically contracted external anal sphincter (EAS), a mild interference pattern often obscures the baseline, affecting the algorithm's ability to determine accurate boundaries of detected MUAPs. To assess the equivalence of
The different parts of the external anal sphincter (EAS) are usually regarded as one muscle with common EMG characteristics. This assumption was addressed by comparing the number of continuously firing motor units (MUs) during relaxation, as well as the parameters of motor unit potentials (MUPs) and
Motor unit potentials (MUP) of the perineal muscles and in particular of the extcrnal anal sphincter (EA sph.), of the external urethral sphincter (EU sph.) and of the bulbocavernosus muscle (BC) have been seldom analyzed. There is no uniformity of view about amplitude and duration of MUP of these m
