OBJECTIVE: The aim of this study was to evaluate the intra and inter-rater reliability of pelvic floor muscle (PFM) dynamometric measurements for maximum and average strengths, as well as endurance. METHOD: A convenience sample of 18 nulliparous women, without any urogynecological complaints, aged between 19 and 31 (mean age of 25.4±3.9) participated in this study. They were evaluated using a pelvic floor dynamometer based on load cell technology. The dynamometric evaluations were repeated in three successive sessions: two on the same day with a rest period of 30 minutes between them, and the third on the following day. All participants were evaluated twice in each session; first by examiner 1 followed by examiner 2. The vaginal dynamometry data were analyzed using three parameters: maximum strength, average strength, and endurance. The Intraclass Correlation Coefficient (ICC) was applied to estimate the PFM dynamometric measurement reliability, considering a good level as being above 0.75. RESULTS: The intra and inter-raters' analyses showed good reliability for maximum strength (ICCintra-rater1=0.96, ICCintra-rater2=0.95, and ICCinter-rater=0.96), average strength (ICCintra-rater1=0.96, ICCintra-rater2=0.94, and ICCinter-rater=0.97), and endurance (ICCintra-rater1=0.88, ICCintra-rater2=0.86, and ICCinter-rater=0.92) dynamometric measurements. CONCLUSIONS: The PFM dynamometric measurements showed good intra- and inter-rater reliability for maximum strength, average strength and endurance, which demonstrates that this is a reliable device that can be used in clinical practice.

ObjectiveTo evaluate the effectiveness of abdominopelvic training by virtual reality compared to pelvic floor muscle training (PFMT) using a gym ball (a previously tested and efficient protocol) on postmenopausal women’s pelvic floor muscle (PFM) strength.MethodA randomized controlled trial was conducted with 60 postmenopausal women, randomly allocated into two groups: Abdominopelvic training by virtual reality – APT_VR (n=30) and PFMT using a gym ball – PFMT_GB (n=30). Both types of training were supervised by the same physical therapist, during 10 sessions each, for 30 minutes. The participants’ PFM strength was evaluated by digital palpation and vaginal dynamometry, considering three different parameters: maximum strength, average strength and endurance. An intention-to-treat approach was used to analyze the participants according to original groups.ResultsNo significant between-group differences were observed in most analyzed parameters. The outcome endurance was higher in the APT_VR group (p=0.003; effect size=0.89; mean difference=1.37; 95% CI=0.46 to 2.28).ConclusionBoth protocols have improved the overall PFM strength, suggesting that both are equally beneficial and can be used in clinical practice. Muscle endurance was higher in patients who trained using virtual reality.

We evaluated primiparous women within 12 to 24 months of delivery and found that VD was associated with PFM avulsion. There was no difference among VD and nonelective or elective CS in symptomatology or other anatomic alterations evaluated through 3D/4D transperineal US.

This virtual reality program promoted an increase in PFM contractility and a decrease in postmenopausal urinary symptoms.

Objective To investigate the feasibility of pelvic floor muscle training (PFMT) through gametherapy for relieving urinary symptoms of climacteric women with stress or mixed urinary incontinence (UI). Methods Randomized clinical trial, divided into two groups: Gametherapy (G_Game) and Control (G_Control). Both groups received recommendations about unsupervised PFMT, and G_Game also received supervised PFMT through gametherapy. After 5 consecutive weeks, the feasibility was investigated considering participant adherence, urinary symptoms (evaluated by the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form [ICIQ-UI-SF] questionnaire), and pelvic floor function (PERFECT Scheme: power, endurance, repetition and fast). The Fisher exact, Kruskal-Wallis, Wilcoxon sign paired, and Mann-Whitney U tests were used by intention-to-treat analysis, using STATA 15.1 (StataCorp, College Station, TX, USA) software. Results The present study included 20 women per group and observed a higher adherence in G_Game. In the intragroup analysis, a decrease in the ICIQ-UI-SF score was observed in both groups (14.0 to 10.0; 13.5 to 0), associated with increased endurance (2.5 to 3.5; 2.5 to 4.0) in G_Control and G_Game, respectively. Moreover, there was a concomitant increase in pelvic floor muscles (PFMs) power (2.0 to 3.0), repetition (3.0 to 5.0), and fast (10.0 to 10.0) in G_Game. In the intergroup analysis, a reduction of UI was observed (p < 0.001; r = 0.8), as well an increase in PFM power (p = 0.027, r = 0.2) and endurance (p = 0.033; r = 0.3) in G_Game. Conclusion The feasibility of supervised PFMT through gametherapy was identified by observing participant adherence, relief of urinary symptoms, and improvement in PFM function.

Introduction and objectives:Several studies have been investigated co-activation can enhance the effectveness of PFM training protocols allowing preventive and therapeutic goals in pelvic floor dysfunctions. The objective of the present study was to investigate if an abdominal-pelvic protocol of training (APT) using gametherapy would allow co-activation of PFM and transversus abdominis/oblique internal (TrA/OI) muscles.Patients and methods:Twenty-five nulliparous, continent, young females, with median age 24.76 (±3.76) years were evaluated using digital palpation (DP) of PFM and surface electromyography of PFM and TrA/OI simultaneously, during maximal voluntary contraction (MVC), alternating PFM and TrA/OI contraction requests. All women participated on a supervised program of APT using gametherapy, that included exercises of pelvic mobilization associated to contraction of TrA/OI muscles oriented by virtual games, for 30 minutes, three times a week, in a total of 10 sessions. Electromyographic data were processed and analyzed by ANOVA - analysis of variance.Results:When MVC of TrA/OI was solicited, it was observed simultaneous increase of electromyographic activity of PFM (p=0.001) following ATP. However, EMG activity did not change significantly during MVC of PFM.Conclusion:Training using gametherapy allowed better co-activation of pelvic floor muscles in response to contraction of TrA, in young nulliparous and continent women.

Background Vulvodynia is a disabling condition in which pelvic floor muscles' (PFM) hypertonicity plays an important role. Aim To evaluate biometric changes in PFM in women with vulvodynia undergoing kinesiotherapy treatment protocol (KTP). Methods A single-blinded randomized controlled trial of 57 women with vulvodynia randomly assigned to either KTP + amitriptyline or amitriptyline alone (controls) for treatment. Four-dimensional translabial ultrasound assessed PFM regarding symphysis-levator distance at rest, anorectal angle at rest, excursion of the levator plate angle, and levator hiatal narrowing. Volunteers underwent a vaginal examination for a cotton swab test (CST), fulfillment of Friedrich criteria score and PFM power of contraction, and completed a diary of sexual pain and frequency of vaginal intercourse. Outcomes were assessed at baseline and after 8 weeks of treatment. Outcomes Primary outcomes were differences in biometric parameters assessed by four-dimensional translabial ultrasound after treatment, between groups. Secondary outcomes were changes in clinical variables (CST, Friedrich criteria, PFM power of contraction, frequency of intercourse, and intensity of sexual pain) between groups and correlation analysis between biometric parameters and clinical variables. Results Only the KTP group had statistically significant changes in biometric parameters after treatment (symphysis-levator distance: 0.22 ± 0.2, 95% CI = 0.1–0.4, P = .008; levator hiatal narrowing: −0.33 ± 0.2, 95% CI = −1 to −0.2, P = .04). Comparisons between groups showed that symphysis-levator distance (0.3, 95% CI = 0.2–0.6, P = .005) and excursion of levator plate angle (4.9, 95% CI = −0.4 to 10.1, P = .02) improved significantly after KTP treatment. Clinical variables showed greater improvement in the group treated with KTP for CST (difference of −3.7, 95% CI = −7 to −0.4, P = .01), Friedrich criteria (difference of −1.9, 95% CI = −3.2 to −0.6, P = .003), PFM power of contraction (0.3, 95% CI = 0.1–0.6, P = .05) and intensity of sexual pain (reduction of 1.7, 95% CI = −3.1 to −0.2, P = .01). Some clinical and biometric variables correlated positively, for example, frequency of vaginal intercourse and anorectal angle (P = .04; r = 0.25), or inversely, for example, pain intensity at CST and anorectal angle (P = .004, r = −0.31). Clinical Implications This study provides evidence on efficiency of a physical therapy protocol for improvement of symptoms of vulvodynia and hypertonicity changes. Conclusion This pilot study suggests that KTP for women with vulvodynia promoted significant changes in PFM biometric measures, consistent with alterations in hypertonicity and clinical improvement.

Objective: The primary objective was to evaluate the impact of app use on urinary incontinence control through pelvic floor muscle training when compared to the postal treatment plan. The secondary objectives were to evaluate how app use may affect the quality of life (QoL) of users and treatment adherence. Material and Methods: Eight databases (PubMed, SciELO, Embase, Web of Science, LILACS, Open Gray, Open Thesis, and OATD) were used as research sources. The protocol was registered in PROSPERO (CRD 42020145709).Randomized controlled trials assessing urinary incontinence (UI) control with app use, with no restriction of year, language, and status of publication were included. The JBI Systematic Reviews Checklist for Randomized Controlled Trials assessed the risk of bias of the studies selected. The mean scores of QoL between the pre-and postintervention periods were compared through standardized mean differences, which were weighted according to the number of months between the two periods. Results: Only three studies met the eligibility criteria and were included. The methodological quality of the studies was from "low" to "moderate" risk of bias.The full sample included 203 patients with app-based treatment e 203 controls of postal treatment. All studies showed the reduction of urinary symptoms. In addition, two studies showed a reduction of QoL scores specific for the condition, while one study presented increased scores.Conclusion: Reminder therapy seems to be a promising strategy for controlling UI.
