“…The evaluation of PFM functioning with the use of surface electromyography, measured during maximal voluntary contraction, showed good to excellent intra-rater reliability (ICC = 0.70–0.98), but the test–retest reliability was poor to good (ICC = 0.20–0.76). In another study, the PFM bioelectrical activity was reported as more reliable, and intra-rater, as well as test–retest, showing moderate to excellent reliability of both time-domains and quantitative parameters of PFM recruitment [ 32 ]. Nonetheless, as was underlined in those studies, the bioelectrical signal measured in the PFMs at rest and during different types of contraction may be influenced by many factors such as the type of vaginal probe, pelvis position during measurement, contact between the probe and surrounding PFMs, subject age or birth status [ 14 ].…”

The aim of this study was to assess the reliability of pelvic floor muscles evaluation via transabdominal ultrasonography in young nulliparous women and to present the methodology for quantitative assessment of the ultrasound image of the pelvic floor muscles visible as displacement of the posterior wall of the bladder, caused by action of the pelvic floor muscles. The study comprised 30 young, Caucasian, nulliparous women (age 22–27; 168.6 ± 5.1 cm; 57.1 ± 11.8 kg) without pelvic floor muscle dysfunctions. The intra-rater, test-retest and inter-rater reliability of pelvic floor muscles evaluation was performed using transabdominal ultrasound at rest and during voluntary contraction. The reliability was assessed at three points of the image (at the middle, on the right and left side). The reliability of the three-point measurement of the pelvic floor muscles transabdominal ultrasound is excellent in the case of intra-rater assessments, both at rest (ICC = 0.98–0.99) and during contraction (ICC = 0.97–0.98); moderate at rest (ICC = 0.54–0.62) and poor during contraction (ICC = 0.22–0.50) in the case of test–retest assessment; excellent at rest (ICC = 0.95–0.96), and good during contraction (ICC = 0.81–0.87) in the case of inter-rater assessment. Transabdominal ultrasound is a reliable method of pelvic floor muscle evaluation. The three-points of assessment used in our study allowed for broader and more comprehensive imaging of the pelvic floor muscle, e.g., for quantitative detection contractility imbalances between the left and right side Due to the fact that understanding mechanisms of pelvic floor muscle functioning is crucial in the therapy of pelvic floor dysfunctions, therefore, reliable, valid tests and instruments are important.

“…The findings of a study by Auchincloss and McLean16 call into question the reliable use of surface EMG for between-subject comparisons or for use as between-day outcome measure. However, Oleksy and colleagues17 demonstrated good (intraclass correlation coefficient ≥ 0.80) between-trial and between-day reliability for average mean and peak amplitude PFM resting tone with 2 different protocols. Participants in both of these studies were adult women with assumedly better motor control ability to isolate PFMs during maximal contractions than children.…”

Purpose: The study aimed to understand the effects of a set of simple gross motor exercises on pelvic floor muscle (PFM) resting tone (RT) in children with dysfunctional voiding symptomology. Methods: The study compared PFM RT for a single-sample before and after 2 protocols: exercise versus relaxation (metric standard). Results: Participants included 27 children ages 5.00 to 10.92 years. Preintervention PFM RT was similar between the interventions: 63% (exercise) and 78% (relaxation) of children decreased PFM RT following intervention. Betweenintervention post-minus-prechanges in PFM RT were compared. Between-intervention differences were similar. Conclusions: Exercise and relaxation protocols were comparable in lowering PFM RT in children with voiding dysfunction. Findings are clinically worthy in that either exercises or relaxation prior to toileting may assist with more complete emptying in children with symptoms.

Purpose This study sought to explore the obstetric factors affecting early postpartum pelvic floor function of primiparas after vaginal delivery. Patients and Methods We included 3362 primiparas who underwent postpartum re-examination in International Peace Maternity and Child Health Hospital at 42–60 days after delivery. The Glazer Protocol was used to evaluate their pelvic floor function, and univariate and multivariate logistic regression analyses were performed to identify obstetric factors that might affect it. Results Forceps-assisted delivery significantly increased the risk of the decline in fast- and slow-twitch muscle strength in the early postpartum period when compared with natural vaginal delivery (P < 0.05). Women with a pre-pregnancy body mass index (BMI) of ≥18.5 kg/m 2 had a decreased risk of decline in fast-twitch muscle strength than those with a pre-pregnancy BMI of <18.5 kg/m 2 (P < 0.05). Women who had a pre-pregnancy BMI of 24.0 to <28.0 kg/m 2 bore a decreased risk of decline in slow-twitch muscle strength than those with a pre-pregnancy BMI of <18.5 kg/m 2 (P < 0.05). The risk of decline in fast-twitch muscle strength and slow-twitch muscle in women with anemia during pregnancy was significantly increased (P < 0.05); women with second-stage labors of >2 h had an increased risk of fast-twitch and slow-twitch muscle strength decline than those with <2 h (P < 0.05). Conclusion Both pre-pregnancy underweight and obesity may cause impairment of early postpartum pelvic floor function. Forceps delivery, anemia during pregnancy, and the length of second stage of labor are independent factors leading to pelvic floor function impairment.
