Objective: To explore the impact of physiological factors, such as age, gender, and childbirth experience, on
external anal sphincter electromyography.
Methods: A total of 62 healthy volunteers (37 women and 25 men) participated in the study.The female subjects
were divided into three groups according to various childbirth experiences: the nulliparous group, the caesarean
group, and the vaginal delivery group. Motor unit potentials were obtained from the bilateral external anal sphincter
of each subject using multi-MUP analysis. The mean values of each parameter (including duration, amplitude, area,
mean number of turns, mean number of phases, and satellite rate) were calculated for each subject. The impact of
age, gender, and childbirth experience on the parameters of the anal sphincter electromyography were analyzed
