Current sEMG systems differ in regard to electrode arrangement and data reproducibility. The aim of this study was to determine the intrasession, intraday, and interday reliabilities of sEMG parameters using a probe with circumferential electrode-position.\n\nMethods\nThe intrasession, intraday, and interday reliabilities of maximum isometric voluntary contractions (MVC) of the pelvic floor muscles were assessed for 19 healthy continent women. Three sEMG parameters that are used to describe muscle activity were verified: maximal EMG (EMGmax), mean over 500 ms around EMGmax (EMGA0.5), and mean over 2 seconds during MVC plateau (EMGA2-4). Relative and absolute reliability parameters were calculated, and the statistical methods described by Bland and Altman were applied to the data.\n\nResults\nWe observed substantial reliabilities for all obtained parameters (EMGmax, EMGA2-4, and EMGA0.5) in regard to the intrasession measurements (ICC = 0.93-0.97; CI = 0.86-0.99). Overall, the intraday reliability has been moderate (ICC = 0.64-0.75; CI = 0.27-0.90). EMGmax (ICC = 0.75; CI = 0.45-0.90) and EMGA2-4 (ICC = 0.73, CI = 0.42-0.89) were higher than EMGA0.5 (ICC = 0.64; CI = 0.27-0.85). However, the interday reliability was only fair for EMGmax (ICC = 0.48; CI = 0.04-0.77) and EMGA0.5 (ICC = 0.51; CI = 0.07-0.78) but moderate for EMGA2-4 (ICC = 0.65; CI = 0.28-0.85).\n\nConclusions\nThis intrasession, intraday, and interday reliability results are similar to the results reported in the literature using probes with longitudinally oriented bars. The mean sEMG signal over 2 seconds (EMGA2-4) exhibited the highest reliability and is recommended for further studies. The interday reliability might be enhanced by considering the menstruation cycle.","annote":"","author":[],"citation-label":"siebert2020intraday","collection-editor":[{"family":"Siebert","given":"Tobias"}],"collection-title":"","container-author":[{"family":"Siebert","given":"Tobias"}],"container-title":"Wiley Online Library Neurourology and Urodynamics","documents":[],"edition":"","editor":[{"family":"Siebert","given":"Tobias"}],"event-date":{"date-parts":[["2020","10"]],"literal":"2020"},"event-place":"","id":"88f633199ed2d6814a99626939d3d01binspo5","interhash":"daa15e055c72f0862fdcf0dab766cd8b","intrahash":"88f633199ed2d6814a99626939d3d01b","issue":"1","issued":{"date-parts":[["2020","10"]],"literal":"2020"},"keyword":"surface isometric voluntary maximal muscles s electromyography PFM pelvic MVC contraction floor EMG","misc":{"doi":"https://doi.org/10.1002/nau.24187"},"note":"","number":"1","number-of-pages":"7","page":"271-278","page-first":"271","publisher":"","publisher-place":"","status":"","title":"Intraday and interday reliability of pelvic floor muscles electromyography in continent woman.

Any mixing of fluid phases is\n\tavoided by using the flow solver in the bulk regions only, and a\n\tghost-fluid approach close to the interface. The coupling states\n\tfor the numerical solution in the bulk regions are determined by\n\tthe solution of local multi-phase Riemann problems across the interface.\n\tThe Riemann solution accounts for the relevant physics by enforcing\n\tappropriate jump conditions at the phase boundary. A wide variety\n\tof interface effects can be handled in a thermodynamically consistent\n\tway. This includes surface tension or mass/energy transfer by phase\n\ttransition. Moreover, the local normal speed of the interface, which\n\tis needed to calculate the time evolution of the interface, is given\n\tby the Riemann solution. The interface tracking itself is based on\n\ta level-set method. The focus in this paper is the description of\n\tthe multi-phase Riemann solver and its usage within the sharp interface\n\tapproach. One-dimensional problems are selected to validate the approach.\n\tFinally, the three-dimensional simulation of a wobbling droplet and\n\ta shock droplet interaction in two dimensions are shown. In both\n\tproblems phase transition and surface tension determine the global\n\tbulk behavior.","annote":"","author":[{"family":"Fechter","given":"Stefan"},{"family":"Munz","given":"Claus-Dieter"},{"family":"Rohde","given":"Christian"},{"family":"Zeiler","given":"Christoph"}],"citation-label":"fechter2017sharp","collection-editor":[],"collection-title":"","container-author":[],"container-title":"J.
