“…However, EMG amplitude was not normalized in any of these studies, putting them at high risk of detection bias [ 141 , 142 ]. Baseline/resting EMG amplitude of the LAM was similar or lower in women with SUI versus continent women in three studies where statistical comparisons between the groups were not performed because of the nature of the studies (i.e, two training studies that did not compare between groups at baseline [ 30 , 31 ] and a reliability study that recruited separate groups of women with and without SUI [ 29 ].…”

The pathophysiology of stress urinary incontinence: a systematic review and meta-analysis

Introduction and hypothesis To evaluate the evidence for pathologies underlying stress urinary incontinence (SUI) in women. Methods For the data sources, a structured search of the peer-reviewed literature (English language; 1960–April 2020) was conducted using predefined key terms in PubMed and Embase. Google Scholar was also searched. Peer-reviewed manuscripts that reported on anatomical, physiological or functional differences between females with signs and/or symptoms consistent with SUI and a concurrently recruited control group of continent females without any substantive urogynecological symptoms. Of 4629 publications screened, 84 met the inclusion criteria and were retained, among which 24 were included in meta-analyses. Results Selection bias was moderate to high; < 25% of studies controlled for major confounding variables for SUI (e.g., age, BMI and parity). There was a lack of standardization of methods among studies, and several measurement issues were identified. Results were synthesized qualitatively, and, where possible, random-effects meta-analyses were conducted. Deficits in urethral and bladder neck structure and support, neuromuscular and mechanical function of the striated urethral sphincter (SUS) and levator ani muscles all appear to be associated with SUI. Meta-analyses showed that observed bladder neck dilation and lower functional urethral length, bladder neck support and maximum urethral closure pressures are strong characteristic signs of SUI. Conclusion The pathology of SUI is multifactorial, with strong evidence pointing to bladder neck and urethral incompetence. While there is also evidence of impaired urethral support and levator ani function, standardized approaches to measurement are needed to generate higher levels of evidence.

“…In addition, in paper III, pregnancy-related complications such as pre-eclampsia, risk of miscarriage, vaginal bleeding and fever were excluded because we used EMG biofeedback to teach PFM contractions at the first visit. Previous studies using EMG biofeedback for PFMT in pregnant women have only included healthy pregnant women (219)(220)(221)(222). Since this was the first time EMG biofeedback was used at Dhulikhel Hospital, the gynaecologists preferred to be extra cautious; therefore, we included only healthy low-risk pregnant women to avoid any complications.…”

Estrogens influence differentially on the pelvic floor muscles activation at somatovisceral reflexes involved in micturition of rabbits

et al. 2021

Objective: To determine the estrogen-dependency of the bladder and urethral function and the coordinated activation of pelvic floor muscles (PFM) during micturition.Methods: We allocated age-matched female rabbits to control, 1-month ovariectomized (OVX), and OVX plus 2-week estradiol benzoate (EB) groups to record cystometry, urethral pressure, and electromyograms of bulbospongiosus (Bsm), and pubococcygeus muscles (Pcm) simultaneously. We also measured serum estradiol levels and myofiber cross-sectional area. We assessed urodynamic and urethral variables, categorized the Bsm-Pcm activation patterns at storage and voiding phases, and obtained the power spectrum density of muscle activation around the voiding phase. We investigated the influence of ovarian hormones, in general, and the contribution of estrogen, particularly on the functions of the bladder, urethra, and PFM. Statistical significance was set at P < 0.05.Results: Ovarian hormones influence the bladder, urethral, and PFM functions. The urodynamics analyses indicated estrogens contribute to voiding duration and, to a lesser extent, to the time between bladder contractions. Urethral pressure at closure (maximal pressure-to-maximal urethral pressure ratio) improved partially (8%, P < 0.05) in the OVX plus 2-week estradiol benzoate compared with OVX, but urethral resistance increased ($1.9-fold, P < 0.05) compared with control rabbits. Our findings support that Pcm activity at voiding is estrogensensitive, albeit EB administration reduced it at storage resume, which relates to high urethral resistance.Conclusions: Ovariectomy impairs bladder and urethral pressures and Bsm and Pcm activation at micturition in anesthetized rabbits. Estrogen administration partially reverts some of these effects and influences Pcm activation.
