<h4>Background</h4>Risks of pelvic organ prolapse and urinary incontinence increase after the first vaginal delivery. During the early postpartum period, a time of active regeneration and healing of the pelvic floor, women may be particularly vulnerable to greater pelvic floor loading.<h4>Objective</h4>This prospective cohort study aimed to determine whether objectively measured moderate to vigorous physical activity in the early postpartum period predicts pelvic floor support and symptoms 1 yea ...[more]

Project description:ObjectiveTo determine whether 2 aspects of trunk recovery after childbirth, intraabdominal pressure (IAP) generation and trunk flexor endurance (TFE), predict measures of pelvic floor health 1 year postpartum.MethodsIn this prospective cohort study, we enrolled nulliparas in their third trimester and followed up those delivered vaginally for 1 year. We measured IAP while lifting a weighted car seat (IAPLIFT), IAP during TFE testing (IAPTFE), and TFE duration 5 to 10 weeks postpartum and assessed pelvic floor support and symptoms 1 year postpartum.ResultsMean age of the 624 participants was 28.7 years. At 5 to 10 weeks postpartum, mean (SD) maximal IAPLIFT and IAPTFE were 47.67 (11.13) and 51.57 (12.34) cm H2O, respectively. Median TFE duration was 126 seconds (Interquartile range, 74-211). At 1 year postpartum, 9.3% demonstrated worse support (maximal vaginal descent at or below hymen) and 54% met criteria for symptom burden (bothersome symptoms in ≥2 domains of Epidemiology of Prolapse and Incontinence Questionnaire). In multivariable models, neither IAPLIFT nor IAPTFE were associated with worse support or symptom burden (P = 0.54-1.00). Trunk flexor endurance duration increased prevalence of worse support (prevalence ratio, 1.05; 95% confidence interval, 1.01-1.08) per 60-second increase, P = 0.005) but not symptom burden (prevalence ratio, 1.00; 95% confidence interval, 0.98-1.03; P = 0.92).ConclusionsThese results provide some reassurance to early postpartum women, who are unlikely to perform routine activities that generate IAP far outside the range tested. Further research is needed to understand why women with long TFE durations have increased prevalence of worse support.

Project description:INTRODUCTION:Pelvic floor disorders (PFDs), including pelvic organ prolapse (POP), stress and urgency urinary incontinence, and faecal incontinence, are common and arise from loss of pelvic support. Although severe disease often does not occur until women become older, pregnancy and childbirth are major risk factors for PFDs, especially POP. We understand little about modifiable factors that impact pelvic floor function recovery after vaginal birth. This National Institutes of Health (NIH)-funded Program Project, 'Bridging physical and cultural determinants of postpartum pelvic floor support and symptoms following vaginal delivery', uses mixed-methods research to study the influences of intra-abdominal pressure, physical activity, body habitus and muscle fitness on pelvic floor support and symptoms as well as the cultural context in which women experience those changes. METHODS AND ANALYSIS:Using quantitative methods, we will evaluate whether pelvic floor support and symptoms 1?year after the first vaginal delivery are affected by biologically plausible factors that may impact muscle, nerve and connective tissue healing during recovery (first 8?weeks postpartum) and strengthening (remainder of the first postpartum year). Using qualitative methods, we will examine cultural aspects of perceptions, explanations of changes in pelvic floor support, and actions taken by Mexican-American and Euro-American primipara, emphasising early changes after childbirth. We will summarise project results in a resource toolkit that will enhance opportunities for dialogue between women, their families and providers, and across lay and medical discourses. We anticipate enrolling up to 1530 nulliparous women into the prospective cohort study during the third trimester, following those who deliver vaginally 1?year postpartum. Participants will be drawn from this cohort to meet the project's aims. ETHICS AND DISSEMINATION:The University of Utah and Intermountain Healthcare Institutional Review Boards approved this study. Data are stored in a secure password-protected database. Papers summarising the primary results and ancillary analyses will be published in peer-reviewed journals.

Project description:BackgroundThere is a risk of pelvic floor dysfunction (PFD) from baby delivery. Many clinical guidelines recommend pelvic floor muscle training (PFMT) as the conservative treatment for PFD because pelvic floor muscles (PFMs) play a crucial role in development of PFD. However, there is disagreement about the method and intensity of PFM training and the relevant measurements. To pilot the study in PFM training, we designed a Pelvic Floor Workout (PEFLOW) for women to train their pelvic through entire body exercises, and we planned a trial to evaluate its effectiveness through comparing the outcomes from a group of postpartum women who perform PELFLOW at home under professional guidance online with the control group.Methods/designThe randomized controlled trial was projected to be conducted from November 2021 to March 2023. A total of 260 postpartum women would be recruited from the obstetrics departments of the study hospital and women would be eligible for participation randomized into experimental or control groups (EG/CG) if their PFM strength are scaled by less than Modified Oxford grading Scale (MOS) to be less than grade 3. Women in EG would perform a 12-week PEFLOW online under the supervision and guidance of a physiotherapist, while women in CG would have no interventions. Assessments would be conducted at enrollment, post intervention (for EG) or 18th to 24th week postpartum (for CG), and 1 year postpartum. Assessment would be performed in terms of pelvic floor symptoms, including MOS, cough stress test, urinary leakage symptoms, pelvic organ prolapse quantitation (POP-Q), and vaginal relaxation, clinic examinations including Pelvic floor electrophysiological test, Pelvic floor ultrasound and Spine X-ray, overall body test including trunk endurance test, handgrip test, body composition test, and questionnaires including International Physical Activity Questionnaire Score-Short Form(IPAQ-SF), Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20), Pelvic Floor Impact Questionnaire-7 (PFIQ-7), the 6-item Female Sexual Function Index (FSFI-6), and the Pittsburgh Sleep Quality Index (PSQI). Primary analysis will be performed to test our main hypothesis that PEFLOW is effective with respect to strengthen PFM strength.DiscussionThis trial will demonstrate that pelvic floor-care is accessible to most women and clinical practice on PFD may change relevantly should this study find that Online PEFLOW approach is effective to improve PFMs.Trial registrationClinicalTrials.gov, NCT05218239.

Project description:ObjectiveThis study aimed to determine whether measures of muscular fitness modify the effect of intra-abdominal pressure (IAP) during lifting on pelvic floor support.MethodsParticipants, primiparous women 1 year after vaginal delivery, underwent the Pelvic Organ Prolapse Quantification examination, measurement of IAP via a vaginal sensor while lifting a weighted car seat, pelvic floor muscle force assessment using an instrumented speculum, grip strength using a hand dynamometer, and trunk flexor endurance by holding an isometric contraction while maintaining a 60-degree angle to the table. We dichotomized pelvic floor support as worse (greatest descent of the anterior, posterior, or apical vagina during maximal strain at or below the hymen) versus better (all points above the hymen).ResultsOf 825 participants eligible after delivery, 593 (71.9%) completed a 1-year study visit. Mean (SD) age was 29.6 (5.0) years. One year postpartum, 55 (9.3%) demonstrated worse support. There were no differences in IAP during lifting or in other measures of pelvic floor loading between women with better and worse support. In multivariable analyses, neither grip strength nor pelvic floor muscle force modified the effect of IAP on support. In women with trunk flexor endurance duration ≥13 minutes, the odds of worse support increased significantly as IAP increased. No fitness measure modified the effect of other measures of pelvic floor loading on support.ConclusionsPrimiparous women with higher IAP during lifting and greater muscular fitness did not have reduced odds of worse pelvic floor support compared with those with lower IAP at the same muscular fitness.

Project description:BackgroundThe aim of this study was to describe the natural course of pelvic floor symptoms and pelvic floor anatomy for women long-term after hysterectomy.MethodsWomen who underwent hysterectomy between 1996-2004 carried out the PFDI-20 questionnaire and POP-Q examination. We collected data on the presence and type of pelvic floor symptoms and its relation to the degree of pelvic organ prolapse (POP) per compartment (≥ stage 2).ResultsWe obtained data from 247 women on average sixteen years after hysterectomy, with no prolapse (n = 94), anterior prolapse (n = 76), posterior prolapse (n = 38), both anterior- and posterior prolapse (n = 20), and a prolapse involving the vaginal vault (n = 19). Of all 153 women with ≥ stage 2 prolapse, 80 (52%) experienced moderate and/or severe symptoms of the PFDI-20. Most frequently reported symptoms by women with POP were uncontrollable flatus, urinary frequency and urge incontinence. Bulging was associated with a prolapse beyond the hymen. 39% Of women without prolapse experienced bothersome pelvic floor symptoms as well. Most often these were stress incontinence, straining to pass stool and incomplete bowel emptying. Women with a history of hysterectomy for prolapse have more pelvic floor symptoms than women who underwent hysterectomy for other indications, regardless of the current presence of POP (57% versus 40%, p = 0.009).ConclusionIn a group of post-hysterectomy women who did not actively seek help, 47% experienced problematic pelvic floor symptoms, independent of the presence or absence of an anatomic POP. Creating more knowledge and awareness of the impact of hysterectomy on the pelvic floor can help women in the future.Trial registrationThe study was registered in the Dutch Trial Registry; Trial NL5967 (NTR6333, 2017-02-01) and approved by the Medical Research Ethics Committee of the Máxima Medical Center (NL60096.015.16, 2017-02-24).

Project description:BackgroundTraumatic sexual experiences can negatively affect sexual functioning and increase pelvic floor activity in women, especially when post-traumatic stress disorder (PTSD) is developed. However, little is known about the effect of other types of interpersonal and non-interpersonal, traumatic experiences on sexual function and pelvic floor overactivity.ObjectiveThe aim of this study was to examine the effects of lifetime traumatic experiences and subsequent PTSD symptoms on sexual function and pelvic floor activity and to investigate whether the effects differ for interpersonal and non-interpersonal trauma.MethodsWomen (N=82) with obesity and a history of infertility, participating in a follow-up study of an RCT investigating a lifestyle intervention programme, completed questionnaires on lifetime exposure to traumatic events (LEC-5), PTSD symptoms (PC-PTSD-5), sexual function (MFSQ) and pelvic floor activity (AOPFS-SV).ResultsA large majority of women (85%) reported exposure to at least one traumatic event during their lifetime. Sexual function and pelvic floor activity did not differ between women who experienced non-interpersonal or interpersonal (including sexual) trauma and those who did not experience traumatic events during their lifetime. Women who had developed PTSD symptoms, however, did have higher pelvic floor activity, but sexual function was not affected. Women with a positive screen for PTSD had the highest pelvic floor activity score, and individual PTSD symptoms nightmares and hypervigilance were associated with significantly higher pelvic floor activity scores.ConclusionTrauma exposure is associated with pelvic floor overactivity in women with a positive screen for PTSD, such that pelvic floor overactivity is more severe with greater PTSD severity. These findings suggest that the development of PTSD after interpersonal trauma is pivotal in this association. Sexual function was unrelated to trauma exposure and pelvic floor function, perhaps related to the fact that the interpersonal trauma events reported in this study were mainly non-sexual.

Project description:Pelvic organ prolapse (POP) and associated symptoms of urinary incontinence, fecal incontinence, obstructive micturition, defecation, and pain are frequent and a widespread disease with relevant reduction of quality of life and high costs. New insights into functional anatomy and pathophysiology of these pelvic floor dysfunctions let us recognize how ligamentous laxities/defects lead to these dysfunctions. Results of the PROpel study (ClinicalTrials.gov-Identifier: NCT00638235) are shown in which a detailed observation of symptoms (patient-related outcome measures) pre- and postoperatively was performed. Ligamentous vaginal repair of POP enables symptom cure in high percentages for urinary urge incontinence (up to 82%), nocturia (up to 92%), obstructive micturition (up to 87%), fecal incontinence (58-72%), obstructive defecation (71-84%), and pain (53-90%), if caused by POP. Women with POP‑Q stage 2 have similar symptom frequencies as women with POP‑Q stage 3-4, and also similar cure rates of their symptoms. If good anatomical prolapse repair (in responders) was achieved, the cure rates for obstructive micturition, urinary urgency incontinence, and nocturia were significantly higher than in those women with less effective surgical repair. In the future, pelvic floor surgery should have symptom cure as the primary objective and should lead to improved quality of life. The different, currently performed techniques for POP repair have to be investigated concerning this matter.

Project description:ObjectivesThis study aimed to explore associations between relative and maximal intra-abdominal pressure (IAP) on pelvic floor outcomes in primiparas delivered vaginally.MethodsAt 5-10 weeks and 1 year postpartum, we measured absolute IAP by vaginal sensor while participants lifted a weighted car seat (IAPLIFT) and performed isometric trunk flexion endurance (IAPTFE) and seated maximal strain (IAPSTRAIN). Primary outcomes, completed 1 year postpartum, included worse pelvic floor support (descent to or beyond the hymen) and positive symptom burden (bothersome symptoms in ≥2 of 6 domains on the Epidemiology of Prolapse and Incontinence Questionnaire). We calculated relative IAP (as absolute IAP/IAPSTRAIN).ResultsOf 542 participants, 9.7% demonstrated worse support and 54.3% demonstrated symptom burden at 1 year postpartum. In multivariable analyses, absolute IAPLIFT and absolute IAPTFE at 5-10 weeks postpartum were not associated with worse support. As relative IAP at 5-10 weeks increased, the prevalence of worse support decreased (prevalence ratio [PR] of 0.77 [95% confidence intervals (CIs), 0.63-0.94] and PR of 0.79 [95% CI, 0.67-0.93]) per 10% increase for relative IAPLIFT and relative IAPTFE, respectively. This was largely due to IAPSTRAIN, which increased the prevalence of worse support (PR, 1.15 [95% CI, 1.06-1.25]) per 10 cm H2O increase. One year postpartum, only IAPSTRAIN increased the prevalence of worse support (PR, 1.11 [95% CI, 1.02-1.20]) per 10 cm H2O. Of all IAP measures at both time points, only absolute IAPLIFT at 1 year significantly increased the prevalence of symptom burden (PR, 1.11 [95% CI, 1.05-1.18]) per 10 cm H2O.ConclusionsThis exploratory analysis suggests that postpartum IAPSTRAIN may increase the prevalence of worse support in primiparas delivered vaginally.

Project description:The impairment of pelvic floor muscle functions and Lactobacillus-deficient vaginal microbiota is common in postpartum women. However, few studies have explored the correlation between pelvic floor muscle functions and vaginal microbiota. Given this research gap, our study aims to investigate any potential association between these two conditions of postpartum women (6-8 weeks after childbirth). A total of 230 women who required postpartum pelvic floor function examination at Peking University International Hospital from December 2021 to April 2022 were enrolled in this study. The collected questionnaire information included progestational weight, body mass index (BMI), weight gain during pregnancy, neonatal weight, delivery type, multiparity, postpartum time, and urinary incontinence (UI). A total of 187 samples of vaginal secretions were collected, and the vaginal microbiota was detected by 16S rRNA sequence analysis. Finally, 183 samples were analyzed in the trial. All individuals were divided into two groups according to the results of pelvic floor muscle assessment to explore the difference between the incidence of postpartum urinary incontinence and vaginal microbiota. We found that the prevalence of UI was higher in the group with weakened pelvic floor muscles. Vaginal delivery, overweight, age, neonatal weight, and weight gain during pregnancy were all risk factors for postpartum urinary incontinence. The vaginal microbiome was no longer Lactobacillus dominant of most postpartum women (91.8%), while the diversity of microbiota increased. The Lactobacillus-deficient community, commonly labeled as community state type (CST) IV, was sub-divided into four communities. The abundance of vaginal Lactobacillus decreased in the group with compromised pelvic muscle functions, while the species richness and diversity increased significantly. In conclusion, the decreased pelvic floor muscle functions of postpartum women 6-8 weeks after delivery may disrupt the balance of vaginal microbiota, and the restoration of pelvic floor functions may contribute to a healthy and balanced vaginal microbiota.

Project description:Introduction and hypothesisVaginal delivery may lead to tearing of the levator ani (LA) muscle from its bony insertions (complete LA avulsion) and increased levator hiatus (LH) area, both risk factors for pelvic floor dysfunctions. Early active rehabilitation is standard treatment after musculo-skeletal injury. We hypothesized that pelvic floor muscle training (PFMT) early postpartum would reduce the presence of LA avulsions and reduce LH area.MethodsWe carried out a planned secondary analysis from a randomized controlled study. Primiparous women (n=175) giving birth vaginally were included 6 weeks postpartum, stratified on complete LA avulsion, and thereafter randomized to PFMT or control. The training participants (n=87) attended a supervised PFMT class once a week and performed home-based PFMT daily for 16 weeks. The control participants (n=88) received no intervention. Presence of complete LA avulsion, LH area at rest, maximal contraction, and maximal Valsalva maneuver were assessed by transperineal ultrasound. Between-group comparisons were analyzed by analysis of covariance for continuous data, and relative risk (RR) for categorical data.ResultsSix months postpartum, the number of women who had complete LA avulsion was reduced from 27 to 14 within the PFMT group (44% reduction) and from 28 to 17 within the control group (39% reduction). The between-group difference was not significant, RR 0.85 (95% CI 0.53 to 1.37). Further, no significant between-group differences were found for LH area at rest, during contraction, or Valsalva.ConclusionsSupervised PFMT class combined with home exercise early postpartum did not reduce the presence of complete LA avulsion or LH area more than natural remission.
