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 [ICC(3,1)] and ICC(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 [T0] and minus 30ms) and reflex activity (T0–30, 30–60, 60–90, 90–120 and 120–150ms after T0) of stretch-reflex latency responses. Results 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±3.7%EMG; P<0.05). ICC(3,k) ranged from 0.67 to 0.91 (SEM 6.1–13.3%EMG and MD 16.7–36.8%EMG) and was higher than ICC(3,1) (range 0.40–0.77; SEM 9.0–18.0%EMG, MD 24.9–50.0%EMG). Conclusions 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. Although we standardized coughing, EMG variables for PFM activity showed poor reliability [good to excellent ICC(3,k) and fair to excellent ICC(3,1) but high SEM and MD]. Therefore, coughing is expected to be heterogeneous, with low reliability, in clinical test situations. Potential crosstalk from other muscles involved in coughing could limit the interpretation of our results.

Reliability of pelvic floor muscle electromyography tested on healthy women and women with pelvic floor muscle dysfunction / Irene Koenig in Annals of physical and rehabilitation medicine, Vol. 60, n° 6 (November 2017)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 60, n° 6 (November 2017) . - p. 382-386 Titre : Reliability of pelvic floor muscle electromyography tested on healthy women and women with pelvic floor muscle dysfunction Type de document : texte imprimé Auteurs : Irene Koenig, Auteur ; Lorenz Radlinger, Auteur ; Helena Luginbuehl, Auteur Année de publication : 2017 Article en page(s) : p. 382-386 Langues : Anglais (eng) Français (fre) Mots-clés : Femme  Muscle  Appareil urogénital [pathologie]  Analyse  Électrodiagnostic  Analysis,Female,Pelvic floor,Reproducibility Résumé : Objectives: Electromyography (EMG) is a well-established method to quantify the relative pelvic floor muscle (PFM) activity. PFM EMG has shown good reliability in healthy women. However, its reliability has not been tested in women with PFM dysfunction. The reliability of EMG analysis methods concerning EMG normalization needs to be determined to assess specific therapeutic interventions. Therefore, the aim of this study was to investigate the intra-session reliability of PFM EMG variables by using 3 different analysis methods in women with PFM dysfunction. Methods: EMG data analysis involved women who were healthy, had weak PFM and had stress urinary incontinence (SUI). We evaluated the reliability of EMG during rest and maximum voluntary contraction and compared muscle activity onset by visual determination and by calculation. All variables were checked for normality (Shapiro-Wilk). Descriptive statistics (mean, SD), systematic error within repeated measures (Wilcoxon) and reliability indexes were tested and presented descriptively (intraclass correlation coefficient [ICC], standard error of measurement [SEM], SEM%, minimal difference [MD], MD%). Results: For 20 women who were healthy, 17 with weak PFM and 50 with SUI, ICC values were high for all variables (0.780–0.994), and SEM and MD values were relatively high (SEM%: 7.5–15.7; MD%: 21.0–43.8). Conclusion: We need reliable methods to analyse clinical intervention studies. PFM EMG variables had high ICCs, but relatively high SEM and MD values modified the reliability. All EMG analysis methods were comparable in healthy women, but only the visual-onset determination was dependable in women with PFM dysfunction.
