摘要

Objectives: Activities that provoke stress urinary incontinence (SUI) rapidly increase the intra-abdominal pressure and the impact loading on the pelvic floor muscles (PFMs). Coughing can cause urinary leakage and is often used to test SUI. However, PFM characteristics during coughing, including their reliability, have not been investigated. Here, we used electromyography (EMG) to describe PFM pre-activity and reflexivity during coughing and examined the reliability of the measurements. Methods: This was an exploratory and reliability study including 11 young healthy women to characterize EMG reflex activity in PFMs during coughing. We describe 6 variables, averaged over 3 coughs per subject, and tested their reliability (intraclass correlation coefficient 3,1 1CC(3,1)J and lCC(3,k), related standard error of measurement (SEM) and minimal difference MD). The variables represented the mean EMG activity for PFMs during 30-ms time intervals of pre-activity (initial time point of coughing TO and minus 30 ms) and reflex activity (TO-30, 30-60, 60-90, 90-120 and 120-150 ms after TO) of stretch-reflex latency responses.
