Pelvic floor muscle training vs radiofrequency for women with vaginal laxity: randomized clinical trial.

BACKGROUND: Vaginal laxity (VL) is a complaint of excessive vaginal looseness with a prevalence ranging from 24% to 38% across studies. AIM: The study sought to compare the effect of radiofrequency (RF) and pelvic floor muscle training (PFMT) on the treatment of women with VL. METHODS: From February 2020 to December 2021, a prospective, parallel, noninferiority, randomized clinical trial was carried out in women ≥18 years of age and complaining of VL in a tertiary hospital. Two groups (RF and PFMT) were evaluated at the beginning of the study and 30 days and 6 months postintervention. A total of 42 participants per arm was sufficient to demonstrate a difference in sexual function on the Female Sexual Function Index at 90% power, 1-sided type 1 error of 0.025 with a noninferiority margin of 4 on the FSFI total score. Analysis was intention-to-treat and per-protocol based. OUTCOMES: The primary endpoint was the change of FSFI score after treatment, and the secondary outcomes were improvement in symptoms of VL and changes in questionnaire scores of sexual distress, vaginal symptoms, and urinary incontinence, in the quantification of pelvic organ prolapse, and pelvic floor muscle (PFM) contraction. RESULTS: Of 167 participants recruited, 87 were included (RF: n = 42; PFMT: n = 45). All questionnaires improved (P < .05) their total scores and subscales in both groups and during the follow-ups. After 30 days of treatment, RF was noninferior to PFMT to improving FSFI total score (mean difference -0.08 [95% confidence interval, -2.58 to 2.42]) in the per-protocol analysis (mean difference -0.46 [95% confidence interval, -2.92 to 1.99]) and in the intention-to-treat analysis; however, this result was not maintained after 6 months of treatment. PFM contraction improved significantly in both groups (RF: P = .006, 30 days; P = .049, 6 months; PFMT: P < .001, 30 days and 6 months), with better results in the PFMT group. CLINICAL IMPLICATIONS: Sexual, vaginal, and urinary symptoms were improved after 30 days and 6 months of treatment with RF and PFMT; however, better results were observed in the PFMT group after 6 months. STRENGTHS & LIMITATIONS: The present randomized clinical trial used several validated questionnaires evaluating quality of life, sexual function and urinary symptoms, in addition to assessing PFM contraction and classifying the quantification of pelvic organ prolapse aiming at anatomical changes in two follow-up periods. The limitations were the lack of a sham-controlled group (third arm) and the difficulty of blinding researchers to assess treatments due to the COVID-19 pandemic. CONCLUSION: After 30 days and 6 months of treatment, sexual, vaginal, and urinary symptoms improved with RF and PFMT; however, better results were observed in the PFMT group after 6 months. RF was noninferior to PFMT in improving FSFI total score after 30 days; however, this result was not maintained after 6 months of treatment.

Impact of pelvic floor muscle strength on female sexual function: retrospective multicentric cross-sectional study.

INTRODUCTION AND HYPOTHESIS: The female pelvic floor muscles (PFM) play an important role in sexual function. We hypothesize that there is a relation between PFM strength and sexual function in women with and without sexual dysfunction. METHODS: Retrospective multicentric cross-sectional study including women with and without sexual dysfunction [Female Sexual Function Index (FSFI) cutoff point < 26.55], analyzed by age range, considering demographic, clinical, anthropometric and PFM strength [Modified Oxford Scale (MOS)] data. Chi-square, Mann-Whitney test and linear regression (ranks) were used, with 5% significance (SAS 9.4). RESULTS: Out of 1013 medical records, 982 women with an average age of 45.76 (± 15.25) were included in the study. Of these, 679 (69.14%) presented FSFI score < 26.55, while 303 (30.86%) presented FSFI ≥ 26.55. It was identified that the higher scores were among white women, < 45 years old, single, with higher education, family income > 4 minimum wages, body mass index < 25 kg/m2, lower parity, regular physical activity practitioner and higher PFM strength (MOS: 4-5). Desire, arousal, lubrication and orgasm domains were higher among women with MOS 4-5, while satisfaction and pain domains were higher among those with MOS 3-5. CONCLUSION: Demographic, clinical and anthropometric conditions can influence both PFM strength and female sexual function. Our findings demonstrate that women with higher PFM strength present fewer complaints about sexual dysfunction.

Effect of radiofrequency and pelvic floor muscle training in the treatment of women with vaginal laxity: A study protocol.

BACKGROUND: Vaginal laxity is an underreported condition that negatively affects women's sexual function and their relationships. Evidence-based studies are needed to better understand this complaint and to discuss its treatment options. Thus, we present a study protocol to compare the effect of radiofrequency and pelvic floor muscle training in the treatment of women with complaints of vaginal laxity. METHODS/DESIGN: This is a prospective, parallel-group, two-arm, randomized clinical trial (Registry: RBR-2zdvfp-REBEC). Participants will be randomly assigned to one of the two groups of intervention (Radiofrequency or Pelvic Floor Muscle Training). The study will be performed in the Urogynecology outpatient clinic and in the physiotherapy outpatient clinic at the State University of Campinas-UNICAMP and will include women aged ≥ 18 years and with self-reported complaints of vaginal laxity. Participants will be assessed at baseline (pre-intervention period) and will be followed up in two periods: first follow-up (30 days after intervention) and second follow-up (six months after intervention). EXPECTED RESULTS: The results of this randomized clinical trial will have a positive impact on the participants' quality of life, as well as add value to the development of treatment options for women with complaints of vaginal laxity. TRIAL REGISTRATION: Registry: RBR-2zdvfp-Registro Brasileiro de Ensaios Clínicos-REBEC (19/02/2020).

Can Supervised Pelvic Floor Muscle Training Through Gametherapy Relieve Urinary Incontinence Symptoms in Climacteric Women? A Feasibility Study.

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.

Pelvic floor muscle assessment by digital palpation and translabial ultrasound of women with cervical or endometrial cancer after pelvic radiotherapy: a cross-sectional study.

INTRODUCTION AND HYPOTHESIS: We hypothesized that anatomical changes in the pelvic floor muscles (PFM) could be detected using four-dimensional translabial ultrasound (4D TLUS) in patients with cervical (CC) or endometrial cancer (EC) who underwent pelvic radiotherapy (RT) as digital palpation may present sensitivity limitations. METHODS: This was a cross-sectional study that included 64 women (26 with CC and 38 with EC). PFM function was assessed by digital palpation, grading muscle strength according to the Modified Oxford Scale and by 4D TLUS. Ultrasonographic variables were: levator plate angle, hiatal area, puborectalis muscle thickness, puborectalis strain and levator ani muscle integrity. These variables were also correlated with clinical and sociodemographic data from all these patients. A 5% significance level was adopted. RESULTS: When assessed by digital palpation, no significant difference was found in PFM strength between women with CC and those with EC (p = 0.747). However, when assessed by 4D TLUS, women with CC presented greater thickening of the left (p = 0.039) and right (p = 0.014) lower portion of the puborectalis muscle during PFM contraction compared to those with EC. After pooling the groups, higher cancer staging (p = 0.028) was associated with smaller narrowing in the symphysis-levator distance, and shorter RT finishing duration (< 60 months) was associated with higher thickening in the left (p = 0.029) and right (p = 0.013) upper portion of the puborectalis muscle during PFM contraction as well as a shorter menopause duration (p = 0.007 and p = 0.002, respectively). CONCLUSIONS: Anatomical changes in the puborectalis muscle during PFM contraction were detected by 4D TLUS within gynecological cancer patients after pelvic RT.

Is pelvic floor muscle strength and thickness associated with pelvic organ prolapse in Nepali women? - A cross-sectional study.

BACKGROUND: Pelvic floor muscle function has been shown to be inversely associated with pelvic organ prolapse in Western women, however differences have been documented between ethnic groups. OBJECTIVE: To determine if pelvic floor muscle strength and thickness and hiatal area are associated with pelvic organ prolapse in Nepali women. METHODS: This cross-sectional study included non-pregnant Nepali women ≥18 years attending an outpatient gynecology clinic in Kathmandu, Nepal. A clinical examination included the pelvic organ prolapse quantification (POP-Q)- system examination and Modified Oxford Scale. Puborectalis muscle thickness and hiatal area were assessed using 3D/4D translabial ultrasound. Statistical analysis included Pearson's correlation and multiple regression (p<0.05). RESULTS: Of the 123 women; 14 (11%) had POP-Q stage 0 prolapse, 29 (24%) stage I, 69 (56%) stage II, 8 (7%) stage III, and 3 (2%) stage IV. Mean±SD Modified Oxford Scale was 3.37±0.48 and muscle thickness was 1.14±0.21cm, hiatal area at rest was 14.67±3.11cm2 and on contraction was 11.29±2.51cm2. No associations were found between pelvic floor muscle strength or thickness and POP-Q stages 0-IV. There was a positive correlation found between hiatal area at rest and pelvic organ prolapse stage (r=0.34, p<0.001)and hiatal area on contraction and prolapse stage (r=0.30, p<0.001) and a negative correlation between pelvic floor muscle strength and hiatal area on contraction (r=-0.36, p<0.001). CONCLUSION: In contrast to previous findings, pelvic floor muscle strength and thickness are not associated with pelvic organ prolapse in this sample of Nepali women. It is important to consider these findings when developing pelvic organ prolapse treatment and management strategies in this population.

Pelvic Floor Biometric Changes Assessed by 4D Translabial Ultrassound in Women With Vulvodynia Submitted to Physical Therapy: A Pilot Study of a Randomized Controlled Trial.

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.

Use of mobile apps for controlling of the urinary incontinence: A systematic review.

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.

Four-dimensional translabial ultrasound concordance with digital palpation and surface electromyography during dynamic pelvic floor muscles assessment: A cross-sectional study.

AIM: To investigate whether pelvic floor muscle (PFM) morphological changes obtained through four-dimensional translabial ultrasound (4D TLUS) correlate with a PFM contraction as evaluated by digital palpation and PFM electromyographic activity evaluated by surface electromyography (sEMG). The secondary objective was to investigate which ultrasound parameter is more strongly associated with digital palpation. METHODS: This cross-sectional study included 210 women and their PFMs were evaluated by digital palpation (graded according to the Modified Oxford Scale), sEMG and 4D TLUS. Offline analysis of ultrasound volume datasets was performed for measuring the change in levator plate angle, bladder neck elevation, hiatal area narrowing, puborectalis strain, and puborectalis muscle thickness at rest and during PFM contraction. Statistical analysis included Kruskal-Wallis, Dunn, and Spearman's tests in addition to univariate and multivariate logistic regression, adopting a significance level of 5%. RESULTS: A weak but significant correlation between the change in levator plate angle and sEMG (P = .04; r = 0.14) was found. All 4D TLUS measurements, except the puborectalis muscle thickness, significantly correlated with digital palpation (P < .0001); with the puborectalis strain and the change in levator plate angle having the strongest combined parameters associated with digital palpation (R2 = 21.77%), despite the low coefficient of determination. CONCLUSION: We found that 4D TLUS significantly correlates with digital palpation and sEMG, being the change in the levator plate angle the parameter that best correlates with both methods. While digital palpation is essential during a PFM functional assessment, 4D TLUS is recommended as a beneficial noninvasive clinical tool for a more in-depth evaluation.

Birthweight and pelvic floor trauma after vaginal childbirth.

INTRODUCTION AND HYPOTHESIS: Birthweight seems to be a risk factor for levator ani muscle (LAM) avulsion and a predictive factor for pelvic organ prolapse (POP). Most trauma seems due to first vaginal birth. METHODS: One thousand one hundred twenty-five women with at least two vaginal deliveries underwent a physician-directed interview, followed by clinical examination (digital palpation and Pelvic Organ Prolapse Quantification-POPQ) and 4D translabial ultrasound. Ultrasound volume data were obtained at rest, on pelvic floor contraction and Valsalva. The investigator, blinded to all other data, performed offline analysis of the LAM integrity and hiatal area on Valsalva. We tested for associations between birthweight of the first and of the largest vaginally born baby on the one hand and avulsion and symptoms/signs of prolapse on the other hand. RESULTS: Between July 2014 and July 2017, 1575 patients were seen. After exclusion of nulliparae and women with just one vaginal birth, 1202 remained. Another 77 were excluded due to missing data, leaving 1125. A significant association was found between birthweight and LAM avulsion as well as significant prolapse on POPQ. The birthweight of the first vaginally born baby was at least as predictive for avulsion as the birthweight of any subsequent births, even when adjusted for maternal age at first delivery and use of forceps. CONCLUSIONS: The birthweight of the first vaginally born baby is associated with levator avulsion and subsequent POP. Maximum weight of vaginal births does not seem to be a stronger predictor.

Clinical and ultrasonographic evaluation of the pelvic floor in primiparous women: a cross-sectional study.

INTRODUCTION AND HYPOTHESIS: We used clinical examination and transperineal 3D/4D ultrasound (US) to evaluate pelvic floor muscles (PFM) after different delivery modes. METHODS: Women were surveyed using validated questionnaires. PFM were evaluated and classified according to the Modified Oxford Scale following 3D/4D transperineal US. For statistical analysis, Kruskal-Wallis, Mann-Whitney, chi-square, and Fisher exact tests were used. RESULTS: Fifty-three women were evaluated: 32 with previous vaginal delivery (VD) and 21 with cesarean section (CS) (8 nonelective and 13 elective). No significant difference among groups was observed regarding urinary incontinence (UI) after delivery (p = 0.39), loss of muscle strength referred by the patient (p = 0.48), or evaluated through digital examination (p = 0.87). No patient with elective CS had avulsion, with difference between VD and elective CS (p = 0.008). US evaluation identified no differences in bladder-neck elevation (p = 0.69) or descent (p = 0.65) , and no difference in genital hiatus size (p = 0.35), levator ani thickness (p = 0.35 -0.44), or presence of major or minor levator ani avulsion (p = 0.10). CONCLUSIONS: 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.

Training through gametherapy promotes coactivation of the pelvic floor and abdominal muscles in young women, nulliparous and continents.

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 surfasse 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.

Training through gametherapy promotes coactivation of the pelvic floor and abdominal muscles in young women, nulliparous and continents

ABSTRACT 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.

The effects of training by virtual reality or gym ball on pelvic floor muscle strength in postmenopausal women: a randomized controlled trial.

OBJECTIVE: To 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. METHOD: A 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. RESULTS: No 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). CONCLUSION: Both 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.

The effects of training by virtual reality or gym ball on pelvic floor muscle strength in postmenopausal women: a randomized controlled trial

ABSTRACT Objective To 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. Method A 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. Results No 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). Conclusion Both 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.

Virtual reality: a proposal for pelvic floor muscle training.

INTRODUCTION AND HYPOTHESIS: This video's proposal was to present one of the pelvic floor muscle (PFM) training programs, used in our research, that we designed as a virtual reality intervention protocol and investigated its effects on PFM contractility. METHODS: Two clinical, controlled and prospective studies were conducted, one with 19 nulliparous women without urinary symptoms, who were evaluated by both electromyography and digital palpation (DP) and another with 27 postmenopausal women with mixed urinary symptoms (assessed by both ICIQ UI-SF and ICIQ-OAB), evaluated by vaginal dynamometry and DP, with a total of 46 women in both studies. This protocol was designed so that the participant would play a video game, seated on a pressure base platform, while commanding it through her pelvic movements. Using a virtual reality game, five activities were performed during 30 min, twice a week, with a total of 10 sessions. RESULTS: A significant increase in PFM strength was found in both the nulliparous (p = 0.0001) and the postmenopausal (p = 0.0001) groups of women, as ascertained by DP. A significant increase in postmenopausal women's muscle strength and endurance assessed by dynamometry (p = 0.05) and a concomitant decrease in their urinary symptoms, were observed. CONCLUSION: This virtual reality program promoted an increase in PFM contractility and a decrease in postmenopausal urinary symptoms.

Abdominopelvic kinesiotherapy for pelvic floor muscle training: a tested proposal in different groups.

INTRODUCTION AND HYPOTHESIS: This video's proposal was to present one of the pelvic floor muscle (PFM) training programs used in our research, and to study the effects of abdominopelvic kinesiotherapy on female PFM function. METHODS: A total of 82 women participated in this study, 11 nulliparous, 13 primiparous pregnant, 20 primiparous postpartum and 38 postmenopausal women, who were evaluated first by digital palpation, then by either electromyography or vaginal dynamometry to investigate their PFM strength, followed by ICIQ UI-SF and ICIQ-OAB to evaluate urinary symptoms. This intervention protocol lasted for 60 min, three times a week, with a total of 10 sessions, and was supervised by a physiotherapist, using a gym ball, according to Marques and collaborators. RESULTS: A significant increase in PFM strength was observed by digital palpation in all groups. This finding was confirmed by electromyography in both pregnant (p = 0.0001) and postpartum (p = 0.0001) groups, as well as in 20 of the 38 women from the postmenopausal group (p = 0.003) then by vaginal dynamometry (p = 0.02) in the rest of the women (18) from the same group, with a concomitant decrease in urinary symptoms (p < 0.05). CONCLUSION: The abdominopelvic kinesiotherapy program promotes an increase in pelvic floor muscle strength and a decrease in urinary symptoms.

Intra and inter-rater reliability study of pelvic floor muscle dynamometric measurements.

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 (ICC(intra-rater1)=0.96, ICC(intra-rater2)=0.95, and ICC(inter-rater)=0.96), average strength (ICC(intra-rater1)=0.96, ICCi(ntra-rater2)=0.94, and ICC(inter-rater)=0.97), and endurance (ICC(intra-rater1)=0.88, ICC(intra-rater2)=0.86, and ICC(inter-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.
