Never Too Late to Train: The Effects of Pelvic Floor Muscle Training on the Shape of the Levator Hiatus in Incontinent Older Women.

ABSTRACT: Pelvic floor muscle (PFM) training is the first-line treatment for women of all ages with urinary incontinence (UI), but evidence supporting its effects on the functional anatomy of the pelvic floor is scarce in older women. We aimed to evaluate the long-term (one-year) effects of PFM training on the shape of the levator hiatus (LH) in older women with UI and its association with PFM force, incontinence severity, and potential effect modifiers (age, UI severity, BMI, and UI type). This is a secondary analysis of the GROUP study, a non-inferiority RCT assessing the effects of a structured and progressive 12-week PFM training program to treat UI in older women. Data were available from 264/308 participants at the one-year follow-up. PFM training resulted in reduced LH size toward a more "circular" shape, which was consistently associated with greater PFM force and reduced UI severity. Further, no significant interactions were found between LH shape changes and any of the potential effect modifiers, suggesting that women will potentially benefit from PFM training, regardless of age, UI severity, BMI, and UI type (stress or mixed), with changes that can be observed in the functional anatomy of the pelvic floor and sustained in the long-term.

Project description:IntroductionPelvic floor muscle training (PFMT) strongly recommended to incontinent pregnant women. The Kegel Exercise Pregnancy Training-app trial is a multicentre cluster-randomised study aims to assess the effectiveness and its cost-effectiveness of the mobile app guidance in PFMT among incontinent pregnant women.Methods and analysis370 pregnant women (aged 18 years old and above) will be recruited with International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form. Ten clusters (primary care clinics) will be randomly assigned to either PFMT or usual care in a 1:1 ratio by an independent researcher (sealed envelope). The primary outcome will be urinary incontinence, and the secondary outcomes (quality of life; PFMT adherence, psychological status and mobile apps' usability) will be assessed at four measurement time points (t0: baseline) and postintervention (t1: 4 weeks, t2: 8 weeks and t3: 8 weeks postnatal). T-test analysis will determine any significant differences at the baseline between the control and intervention groups. The mixed-model analysis will determine the effectiveness of the intervention at the population-average level for both the primary and secondary outcomes. For the cost-effectiveness analysis, expenditures during the study and 6 months after the intervention will be compared between the groups using the multiway sensitivity analysis. The recruitment planned will be in December 2020, and the planned end of the study will be in August 2021.Ethics and disseminationThis study protocol was approved by the Ethics Committee for Research Involving Human Subjects, Universiti Putra Malaysia (JKEUPM-2019-368) and Medical Research and Ethics Committee (MREC), Ministry of Health Malaysia, NMRR-19-412-47116 (IIR) with the ANZCTR registration. This study will obtain informed written consent from all the study participants. The results which conform with the Consolidated Standards of Reporting Trials and the Recommendations for Interventional Trials will be published for dissemination in peer-reviewed journals and conference proceedings.Trial registration numberACTRN12619000379112.

Project description:BackgroundWe believe that physiotherapy with muscle training (MT) of the postpartum pelvic floor may lead to a change in the clinical management of patients with avulsion of the puborectal portion of the levator ani muscle (LAM). Our objective is to assess whether physiotherapy with MT of the postpartum pelvic floor in patients with LAM avulsion produces changes in pelvic floor morphology evaluated by 3/4D transperineal ultrasound.MethodsThis parallel randomized controlled trial (RCT) included 97 primiparous patients. A study was conducted in three parts. In the first part (3 months postpartum), primiparous patients with LAM avulsion were recruited, and the levator hiatus and the LAM areas were measured using 3/4D transperineal ultrasound. In the second part (3 to 6 months postpartum), patients were randomized into two groups, with one undergoing rehabilitation (experimental group) and another without rehabilitation (control group). At the end of 6 months, a new transperineal ultrasound was performed. In the third part (9 months postpartum), the levator hiatus and LAM dimensions were analyzed again. The RCT was registered at ClinicalTrials.gov (NCT03686956). Project PI16/01387 funded by Instituto de Salud Carlos III (Spain) integrated in the national I+D+i 2013-2016 and cofounded by the European Union (ERDF/ESF, "Investing in your future").ResultsA total of 92 completed the study, including 46 patients in the experimental group and 46 in the control group. The experimental group had a greater LAM area at 6 months (9.2±1.9 vs. 7.6±2.1 cm2, P=0.008; 95% CI: 0.6-3.0) and 9 months after labor (9.4±2.7 vs. 7.6±2.0 cm2, P=0.012; 95% CI: 0.4-3.2), which was not observed at 3 months postpartum (8.3±1.6 vs. 7.5±2.3 cm2; P=0.183; 95% CI: 0.39-1.99). The levator hiatus area decreased more in the experimental group in almost all comparisons. The most significant change occurred from 3 to 6 months during the Valsalva maneuver (-3.92±5.12 vs. 0.45±3.06 cm2; P<0.005; 95% CI: 2.64-5.00).ConclusionsWomen with a rehabilitated LAM through physiotherapy showed a significant reduction in the levator hiatus area during Valsalva while receiving in-person physical therapy (3 to 6 months after delivery). These differences did not persist once physical therapy was completed (6 to 9 months after delivery).Trial registrationClinicalTrials.gov identifier NCT03686956.
