used real-time dynamic MRI and found a mean PFM downward movement of 7.4 В± 5.8 mm during coughing in healthy nulliparous women in the supine position. investigated vesical neck descent by using ultrasonography during coughing in standing continent nulliparous women and found a mean downward movement of 8.2 В± 4.1 mm. Both groups concluded that this gradual PFM adaptation might be one of the main factors contributing to urinary and fecal continence in women. also compared SUI affected with continent women and found a lack of modulated PFM response during successive coughing efforts. The authors concluded that the cough anal reflex is not an unambiguous response (response or non-response) but rather a modulated reflex. investigated external anal sphincter electromyography (EMG) during coughing and found that cough intensity was significantly related to EMG activity for the anal sphincter. ДЇast and high impact loads on the PFMs require reflexive muscle contractions to guarantee continence.

Such impact loads occur within milliseconds (ms) for example, peak-flow happens within 57 to 110 ms during coughing in women. Activities or efforts that typically provoke SUI rapidly increase the intra-abdominal pressure and the impact loading on the pelvic floor muscles (PFMs). Stress leakage is presumed to be due to increased abdominal pressure. The signs of stress urinary incontinence (SUI) are involuntary leakage from the urethra with effort or physical exertion or on sneezing or coughing. Potential crosstalk from other muscles involved in coughing could limit the interpretation of our results. Therefore, coughing is expected to be heterogeneous, with low reliability, in clinical test situations. Although we standardized coughing, EMG variables for PFM activity showed poor reliability. PFM activity during reflex latency response time intervals during coughing was significantly higher than at rest, which suggests PFM pre-activity and reflex activity during coughing. The mean %EMG (normalized to maximal voluntary PFM contraction) for EMG variables was 35.1 to 52.2 and was significantly higher during coughing than for PFM activity at rest (mean 24.9 В± 3.7%EMG P < 0.05). The variables represented the mean EMG activity for PFMs during 30-ms time intervals of pre-activity (initial time point of coughing and minus 30 ms) and reflex activity ( T 0вЂ“30, 30вЂ“60, 60вЂ“90, 90вЂ“120 and 120вЂ“150 ms after T 0) of stretch-reflex latency responses. We describe 6 variables, averaged over 3 coughs per subject, and tested their reliability (intraclass correlation coefficient 3,1 and ICC(3, k ), related standard error of measurement (SEM) and minimal difference ). This was an exploratory and reliability study including 11 young healthy women to characterize EMG reflex activity in PFMs during coughing. Here, we used electromyography (EMG) to describe PFM pre-activity and reflexivity during coughing and examined the reliability of the measurements. However, PFM characteristics during coughing, including their reliability, have not been investigated. Coughing can cause urinary leakage and is often used to test SUI.

Activities that provoke stress urinary incontinence (SUI) rapidly increase the intra-abdominal pressure and the impact loading on the pelvic floor muscles (PFMs).
