Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women

Group early intervention eye movement desensitization and reprocessing therapy as a video-conference psychotherapy with frontline/emergency workers in response to the COVID-19 pandemic in the treatment of post-traumatic stress disorder and moral injury—An RCT study

Objective

Frontline mental health, emergency, law enforcement, and social workers have faced unprecedented psychological distress in responding to the COVID-19 pandemic. The purpose of the RCT (Randomized Controls Trial) study was to investigate the effectiveness of a Group EMDR (Eye Movement Desensitization and Reprocessing) therapy (Group Traumatic Episode Protocol—GTEP) in the treatment of Post-Traumatic Stress Disorder (PTSD) and Moral Injury. The treatment focus is an early intervention, group trauma treatment, delivered remotely as video-conference psychotherapy (VCP). This early intervention used an intensive treatment delivery of 4x2h sessions over 1-week. Additionally, the group EMDR intervention utilized therapist rotation in treatment delivery.

Methods

The study’s design comprised a delayed (1-month) treatment intervention (control) versus an active group. Measurements included the International Trauma Questionnaire (ITQ), Generalized Anxiety Disorder Assessment (GAD-7), Patient Health Questionnaire (PHQ-9), Moral Injury Events Scale (MIES), and a Quality-of-Life psychometric (EQ-5D), tested at T0, T1: pre—treatment, T2: post-treatment, T3: 1-month follow-up (FU), T4: 3-month FU, and T5: 6-month FU. The Adverse Childhood Experiences – International version (ACEs), Benevolent Childhood Experience (BCEs) was ascertained at pre-treatment only. N = 85 completed the study.

Results

Results highlight a significant treatment effect within both active and control groups. Post Hoc comparisons of the ITQ demonstrated a significant difference between T1 pre (mean 36.8, SD 14.8) and T2 post (21.2, 15.1) (t11.58) = 15.68, p < 0.001). Further changes were also seen related to co-morbid factors. Post Hoc comparisons of the GAD-7 demonstrated significant difference between T1 pre (11.2, 4.91) and T2 post (6.49, 4.73) (t = 6.22) = 4.41, p < 0.001; with significant difference also with the PHQ-9 between T1 pre (11.7, 5.68) and T2 post (6.64, 5.79) (t = 6.30) = 3.95, p < 0.001, d = 0.71. The treatment effect occurred irrespective of either ACEs/BCEs during childhood. However, regarding Moral Injury, the MIES demonstrated no treatment effect between T1 pre and T5 6-month FU. The study’s findings discuss the impact of Group EMDR therapy delivered remotely as video-conference psychotherapy (VCP) and the benefits of including a therapist/rotation model as a means of treatment delivery. However, despite promising results suggesting a large treatment effect in the treatment of trauma and adverse memories, including co-morbid symptoms, research results yielded no treatment effect in frontline/emergency workers in addressing moral injury related to the COVID-19 pandemic.

Conclusion

The NICE (2018) guidance on PTSD highlighted the paucity of EMDR therapy research used as an early intervention. The primary rationale for this study was to address this critical issue. In summary, treatment results for group EMDR, delivered virtually, intensively, using therapist rotation are tentatively promising, however, the moral dimensions of trauma need consideration for future research, intervention development, and potential for further scalability. The data contributes to the emerging literature on early trauma interventions.

Pelvic Floor Disorders and Pelvic Floor Muscle Exercise: A Survey on Knowledge, Attitude, and Practice among Pregnant Women in Northwest Ethiopia

The purpose of the study was to investigate 1: overall knowledge of pelvic organ prolapse (POP) and urinary incontinence (UI) as well as knowledge, attitudes, and practice of pelvic floor muscle exercise (PFME); and 2: the association of these factors with parity in pregnant women in Gondar, Ethiopia. A facility-based cross-sectional study was performed in the Central Gondar zone, northwest Ethiopia between February and April 2021. The associations between parity and knowledge of POP and UI, and knowledge, attitude, and practice towards PFME were estimated using logistics regression models and presented as crude and adjusted odds ratios with 95% confidence intervals. Nulliparous women were used as the reference. Adjustments were made for maternal age, antenatal care visits, and level of education. The study sample comprised 502 pregnant women: 133 nulliparous, and 369 multiparous. We found no association between parity and knowledge of POP, UI, or knowledge, attitude, and practice toward PFME. The sum score indicated poor knowledge about both POP, UI, and PFME in the study population, and poor attitude and practice of PFME. Despite a high attendance in antenatal care services, knowledge, attitude, and practice were poor, indicating a need for quality improvement of the services.

Educational Technology on Urinary Incontinence during Pregnancy: Development and Validation of an Online Course for the Brazilian Population

Objective: To describe the development and validation process of an online course on urinary incontinence during pregnancy in Brazil. Materials and methods: This methodological study followed an online course’s literature search, development, and validation steps. A total of 22 specialists participated in the validation step, and the content validity index (CVI) was used. Fifty-one Physical Therapy students (target audience) also participated in the Suitability Assessment of Materials. Results: The synthesis reached in the integrative review provided the basis for the course’s theoretical content, which was regarded as suitable by the specialists regarding its content, language, presentation, stimulation/motivation, and cultural adequacy (CVI = 0.99). The target audience considered the course organized, easily understandable, engaging, and motivational, with a positive response index ranging from 84.3 % to 100 %. Conclusions: The Brazilian version of the online course was considered sufficiently adequate in content and interface quality by both specialists and the target audience.

The "Mother Load" and Return to Sport: A Case Report of Returning to Professional Netball Following Cesarean Section

Background

Increasing numbers of elite female athletes are competing in professional sport, and many wish to become pregnant and return to competitive sport after childbirth. Athletes have a higher risk of pelvic floor dysfunction (PFD) than non-athletes (54% versus 7%) and there is also an increased prevalence in post-partum women compared to nulliparous women (35% versus 2.8-7.9%). Additionally, PFD has been shown to influence athletic performance. High quality evidence for elite athletes is lacking, and there are no exercise guidelines specifically for these women to prepare or effectively guide their safe return to sport (RTS). The purpose of this case report is to detail the management of an elite athlete who presented following cesarean section (CS) with the goal of RTS within 16 weeks.

Case Description

A 27-year-old primiparous Caucasian professional netballer presented at four weeks post- caesarean section (CS) for RTS screening and assessment of pelvic floor muscle (PFM) function. Assessment included readiness and fear of movement screening, dynamic pelvic floor muscle function, structural integrity of the CS wound, levator hiatal dimensions, bladder neck descent, and early global neuromuscular screening. Measures were collected at four weeks, eight weeks, and six months post-partum. The post-partum athlete demonstrated alterations in pelvic floor muscle function, reduced lower limb power and psychological readiness. A functionally staged dynamic and sport specific pelvic floor muscle training program was implemented and adapted to the patient for her early post-partum timeline.

Results

Rehabilitation strategies were effective in achieving the primary outcome of RTS at 16 weeks post-partum with no adverse events reported at 6 months follow-up.

Discussion

This case highlights the need for a holistic and individualised RTS management approach that includes women's and pelvic health risk factors in a professional athlete.

Strenuous physical activity, exercise, and pelvic organ prolapse: a narrative scoping review

INTRODUCTION AND HYPOTHESIS

High-intensity physical activity and exercise have been listed as possible risk factors for pelvic organ prolapse (POP). The aim of the present study is to conduct a literature review on the prevalence and incidence of POP in women who engage in regular physical activity. In addition, we review the effects of a single exercise or a single session of exercise on pelvic floor support. Finally, the effect of exercises on POP in the early postpartum period is reviewed.

METHODS

This is a narrative scoping review. We searched PubMed and Ovid Medline, the Physiotherapy Evidence Database (PEDro), and the Cochrane Database of Systematic Reviews up to May 2022 with the following MeSH terms: "physical activity" AND "exercise" AND "pelvic floor" AND "pelvic organ prolapse".

RESULTS

Eight prevalence studies were retrieved. Prevalence rates of symptomatic POP varied between 0 (small study within different sports) and 23% (Olympic weightlifters and power lifters). Parity was the only factor associated with POP in most studies. Three studies evaluated the pelvic floor after a single exercise or one session of exercise and found increased vaginal descent or increased POP symptoms. One prospective cohort study reported the development of POP after 6 weeks of military parashot training, and one randomized trial reported increased POP symptoms after transverse abdominal training. There is scant knowledge on exercise and POP in the postpartum period.

CONCLUSIONS

Prevalence of POP in sports varies widely. Experimental and prospective studies indicate that strenuous exercise increased POP symptoms and reduced pelvic floor support.

Does a Kegel Exercise Program Prior to Resistance Training Reduce the Risk of Stress Urinary Incontinence?

This comparative pre-post intervention study investigated the feasibility and benefits of Kegel exercises amongst incontinent women, prior to commencing resistance training (RT), to reduce the risk of stress urinary incontinence (SUI) compared to a group of women without prior Kegel exercises (KE). Incontinence severity index (ISI) score, pelvic floor muscle strength (PFMS), and body composition (such as body mass index (BMI), fat, and muscle mass), were obtained pre and post intervention. Results demonstrated that RT reduced SUI to a significantly greater extent only if preceded by KE as was observed in the Kegel exercise plus RT group (KE + RT) over time. The improvements in total ISI in both the KE + RT and RT groups were large (d = 1.50 and d = 1.17 respectively). A two-way ANOVA indicated a statistically significant improvement in average PFMS within the KE + RT group over time and between the two groups. A positive correlation was found between the average strength of pelvic floor muscles and SUI. Participants in KE + RT group demonstrated a significant increase in muscle mass (p ≤ 0.001) and concomitant reduction in fat mass (p = 0.018). This study determined a dedicated program of KE preceding a RT program improved average pelvic floor muscle strength and was effective in reducing SUI among incontinent women.

How about the RCTs' quality of acupuncture treatment for female urinary incontinence in recent 20 years? A report quality assessment

PURPOSE

To evaluate the quality of randomized controlled trials (RCTs) of acupuncture on female urinary incontinence (UI).

METHODS

We searched for related RCTs of acupuncture on female UI from seven databases (PubMed, Embase, Cochrane library, Web of Science, Medline, ClinicalKey, and Clinical trials). We applied CONSORT (2010 year) and STRICTA criteria to evaluate the relevant factors of included RCTs. Two trained researchers scored independently, and concordance was assessed by Cohen's к-statistic. The median and interquartile range summarized the CONSORT and STRICTA scores of the included studies. In addition, two independent sample t tests were used to assess the differences in the study quality between the 2000-2010 and the 2011-2022 years.

RESULTS

A total of 25 RCTs were finally included, and the scores were consistent between different assessors. The average CONSORT score was 10.50 (IQR 9.0-15.0) (total score was 25.0). Overall, the studies generally included scientific background (24/25, 96%), inclusion and exclusion criteria (24/25, 96%), outcome indicators (24/25, 96%), randomization methods (21/25, 84%), generalizability (19/25, 76%), and financial support (15/25, 60%). Most lacked sample size calculation (5/25, 20%), type of randomization (5/25, 20%), blinding (6/25, 24%), case screening period and follow-up (4/25, 16%), and study registration (6/25, 24%), etc. The average STRICTA score was 3.380 (IQR 3.02-3.95) (total score was 6.0). There had a lack of education on treatment methods for patients (3/25, 12%) and the qualification of acupuncturists (6/25, 24%).

CONCLUSION

The overall quality of RCTs on acupuncture treatment of female UI was suboptimal. It is still necessary to improve the research methods, especially the application of random methods, blinding, the interpretation of treatment, and the identification qualification of acupuncturists.

Long-term effects and costs of pelvic floor muscle training for prolapse: trial follow-up record-linkage study

INTRODUCTION AND HYPOTHESIS

Pelvic organ prolapse affects around 40% of women aged over 50 years. A multicentre parallel group randomised trial (the Pelvic Organ Prolapse PhysiotherapY (POPPY) trial) demonstrated that pelvic floor muscle training (PFMT) was effective in reducing prolapse symptoms compared with no treatment. However, insight into the long-term impact of PFMT on health outcomes and health-service utilisation is scarce.

METHODS

This study utilised linkage of Scottish administrative health records to follow-up POPPY trial participants resident in Scotland over 11 years. Mixed effects logistic regression determined the likelihood of receiving further prolapse treatment for those in the PFMT and control groups. Analyses were adjusted for age group, prolapse stage, baseline symptom severity and attitude towards surgery. A cost assessment estimated longitudinal costs to the UK National Health Service (in Scotland) of accessing further prolapse treatment for each trial group.

RESULTS

Two hundred and ninety-three women, aged 25 to 79 years, were followed up. One hundred and forty-one women (48.1%) had received further prolapse treatment: 65 (of 149; 43.6%) in the PFMT group compared with 76 (of 144; 52.8%) in the control group. PFMT was associated with a reduction in the odds of any prolapse treatment during follow-up (AOR 0.61; 95% CI 0.37 to 0.99). Total cost of secondary care was £154,544 (GBP) in the PFMT group and £172,549 (GBP) in the control group.

CONCLUSIONS

Although PFMT did not lead to significant differences in total costs for further prolapse treatment over a post-intervention period of more than 10 years, it reduced the overall long-term risk of requiring hospital-based treatment for pelvic floor disorders.

The feasibility of pelvic floor training to treat urinary incontinence in women with breast cancer: a telehealth intervention trial

PURPOSE

To investigate the feasibility of recruiting into a pelvic floor muscle training (PFMT) program delivered via telehealth to treat urinary incontinence (UI) in women with breast cancer on aromatase inhibitors.

METHODS

We conducted a pre-post single cohort clinical trial with 54 women with breast cancer. Participants underwent a 12-week PFMT program using an intra-vaginal pressure biofeedback device: femfit^®. The intervention included eight supervised individual PFMT sessions over Zoom^™ and a 12-week home exercise program. The primary outcome of this study was feasibility, specifically consent rate. Secondary outcomes which included prevalence and burden of UI measured using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), and pelvic floor muscle (PFM) strength measured as intravaginal squeeze pressure were compared using McNemar's and paired t tests.

RESULTS

The mean age of participants was 50 years (SD ± 7.3). All women who were eligible to participate in this study consented (n = 55/55, 100%). All participants reported that the program was beneficial and tailored to their needs. The results showed a statistically significant decline in the prevalence (percentage difference 42%, 95% CI 28, 57%) and burden (ICIQ-UI SF score mean change 9.4, 95% CI 8.5, 10.4) of UI post intervention. A significant increase in PFM strength was observed post-intervention (mean change 4.8 mmHg, 95% CI 3.9, 5.5).

CONCLUSION

This study indicated that PFMT delivered via telehealth may be feasible and potentially beneficial in treating stress UI in women with breast cancer. Further studies such as randomized controlled trials are required to confirm these results.

Comparing Periurethral Injection of Autologous Muscle-Derived Stem Cell and Fibroblasts with Mid-Urethral Sling Surgery in the Treatment of Female Stress Urinary Incontinence: A Randomized Clinical Trial

Objective

In this study, we analyzed the therapeutic effect of periurethral injection of autologous muscle-derived stem cell versus mid-urethral sling surgery at a 1-year follow-up.

Method

This randomized controlled clinical trial was conducted on 30 women with stress urinary incontinence (SUI) who had not responded to conservative treatments, after registering the participants and obtaining informed consent. Patients were divided into two groups of 15 each treated with periurethral injection of muscle-derived stem cells (MDSCs) and mid-urethral sling surgery, respectively. Follow-ups were done at 1, 3, 6, and 12 months after the treatment using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UISF) and Incontinence Quality of Life Questionnaire (I-QOL) questionnaires, clinical examination, cough test, and 1-hour pad test. The results were analyzed within the groups and then compared between the two groups. Moreover, both groups were compared in terms of postoperative complications.

Results

At the 1-year follow-up, in the stem cell group, 10 patients (66.6%) experienced improvements after the periurethral injection of stem cells; half of these patients (33.3%) reported a full recovery. In the mid-urethral sling group, 13 patients (93.3%) experienced improvement, and 12 patients (80%) reported a full recovery. The analysis of ICIQ-UISF and I-QOL questionnaires indicated that the responses in both groups were significant, but the response in the stem cell group was significantly lower compared with the standard surgery group. No considerable complications were observed in the two groups.

Conclusion

Although the periurethral injection of MDSCs considerably improves the symptoms with minimum complications in women with SUI, its therapeutic response is significantly lower compared with mid-urethral sling surgery.

The effectiveness of eHealth interventions on female pelvic floor dysfunction: a systematic review and meta-analysis

INTRODUCTION AND HYPOTHESIS

eHealth interventions represent a promising novel strategy in pelvic floor management for women. Nevertheless, the effectiveness of eHealth interventions among women with or at risk of pelvic floor dysfunction (PFD) has not been adequately discussed to date. This study aimed to determine the effectiveness of eHealth interventions in preventing and treating PFD among women.

METHODS

Eleven electronic databases were searched for randomized controlled trials (RCTs) from inception until August 28, 2021.

RESULTS

Twenty-four RCTs were included in this meta-analysis that included 3691 women. The meta-analysis showed that eHealth interventions were not only vital for preventing PFD (pregnant women: pooled OR = 0.25, 95% CI: 0.14 to 0.45, p < 0.001; postnatal women: pooled OR = 0.19, 95% CI: 0.06 to 0.60, p = 0.005), but also for reducing the severity of PFD (pooled SMD = -0.63, 95% CI: -1.20 to -0.06, p = 0.031). In addition, compared with traditional care, eHealth interventions showed significant positive effects on several outcome indicators, including quality of life (pooled SMD = 0.49, 95% CI: 0.19 to 0.80, p = 0.002), pelvic floor type I muscle strength (pooled OR = 1.92, 95% CI: 1.30 to 2.82, p = 0.001), pelvic floor type II muscle strength (pooled OR = 2.04, 95% CI: 1.38 to 3.01, p < 0.001), sexual function (pooled SMD = 0.51, 95% CI: 0.29 to 0.73, p < 0.001), satisfaction (pooled OR = 3.93, 95% CI: 2.73 to 5.66, p < 0.001), and self-efficacy (pooled SMD = 2.62, 95% CI: 2.12 to 3.13, p < 0.001).

CONCLUSIONS

eHealth interventions are an effective emerging treatment and preventive modality for female PFD. Higher quality, larger scale, and strictly designed RCTs are warranted to evaluate the effectiveness of eHealth interventions on female pelvic floor management.

Attitudes and barriers to pelvic floor muscle exercises of women with stress urinary incontinence

Background

Pelvic floor muscle exercise (PFME) is a first-line treatment for stress urinary incontinence (SUI), but adherence to PFME is often problematic. The aim of this study was to better understand the attitudes and barriers to practicing pelvic floor muscle exercise among women with SUI.

Methods

We conducted a qualitative study using semi-structured interviews. Purposive sampling was used to approach eligible participants. The interview included questions focused on women’s perceptions regarding SUI and PFME, sources of information, support, and barriers and motivators of PFME. In-depth interviews were conducted until data saturation occurred. After several readings of written interview transcripts, codes were retrieved, and thematic analysis was conducted.

Results

Seven women participated in the study (average age 53.2 years), and most (4/7) were retired. Three salient themes emerged from the data: (1) perception of SUI, (2) barriers to PFME, and (3) motivators to exercise. Participants highlighted various barriers to PFME: (1) lack of self-discipline owing to both intrinsic and extrinsic factors, (2) lack of confidence in how to perform the exercises properly, and (3) skepticism regarding the efficacy of treatment according to women’s direct and indirect experiences. Achievement of desired outcomes, symptom severity, women’s expectations, and fear of surgery were motivators to regularly perform PFME.

Conclusions

The main barriers to regular PFME were inadequate self-discipline, knowledge, and confidence in performing the exercises, and a poor perception about the effectiveness of PFME.

Efficacy of Biofeedback and Electrostimulation-Assisted Pelvic Floor Muscle Training between Women with Mild and Moderate to Severe Stress Urinary Incontinence

BACKGROUND

To evaluate the efficacy of biofeedback and electrical stimulation-assisted pelvic floor muscle training (PFMT) between women with mild and moderate to severe stress urinary incontinence (SUI).

METHODS

This retrospective cohort study was conducted at a single center from 2014 to 2021. We included 57 patients with urodynamically proven SUI who underwent a biofeedback and electrical stimulation-assisted PFMT. They were categorized into mild and moderate to severe SUI. One-hour pad test from 2 to 10 g was defined as mild SUI, and ≥11 g was defined as moderate to severe SUI.

RESULTS

Fifty-seven patients were reviewed during the study period. Incontinence-related symptoms of distress, including the UDI-6, ISI, and VAS, all significantly improved in the mild SUI group (p = 0.001, p = 0.001 and p = 0.010, respectively), while only UDI-6 and VAS statistically improved in the moderate to severe SUI group (p = 0.027 and p = 0.010, respectively). There was significant improvement in IIQ-7 in the mild SUI group during serial treatments, but only in Session 6 in the moderate to severe SUI group. After 18 sessions of treatment, the UDI-6, ISI, and IIQ-7 scores showed significantly greater improvements in the mild SUI group compared to the moderate to severe SUI group (p = 0.003, p = 0.025, and p = 0.002, respectively).

CONCLUSIONS

Although biofeedback and electrical stimulation-assisted PFMT is an effective treatment option for SUI, it is more beneficial for patients with mild SUI and a 1-h pad weight ≤ 10 g urine leak.

Feasibility, acceptability and effects of a group pelvic floor muscle telerehabilitation program to treat urinary incontinence in older women

INTRODUCTION

Urinary incontinence (UI) is one of the most prevalent health concerns in women age 65 and over. The recommended first-line treatment for UI is individual pelvic floor muscle training (PFMT). However, healthcare systems worldwide are unable to meet the demand for this resource-intensive approach. Recently, the Group Rehabilitation Or IndividUal Physiotherapy (GROUP) trial showed that group-based PFMT was not inferior to individual PFMT to treat UI in older women, despite using fewer resources. This study aims to assess the feasibility, acceptability and effects on UI-related symptoms and associated quality of life (QoL) of an online adaptation of the GROUP program (teleGROUP) for UI in older women.

METHODS AND ANALYSIS

This pilot study will involve the recruitment of 32 older women with UI. Participants' attendance to online sessions, adherence to weekly home exercises, and side effects, in addition to the physiotherapist's fidelity to the program delivery will be collected to evaluate the program's feasibility. Participants' dropout rates, reasons for dropout, satisfaction and usability scores will be collected to evaluate the program's acceptability for participants. A survey will evaluate the program's acceptability for the physiotherapists. Additionally, at the end of the study, qualitative semi-structured interviews and focus groups will investigate further feasibility and acceptability. To measure the effects of teleGROUP, number of weekly leakages and percentage reduction will be the primary outcomes.

The development of a physical therapy service to treat urinary incontinence: Results of a RE-AIM evaluation

Background

A conservative physiotherapy service development addressed to treat urinary incontinence for older women was studied using the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework.

Design

We conducted a pragmatic case study design based on RE-AIM.

Settings/participants

Included women ≥ 60 years of age, with self-reported UI symptoms.

Results

A total of 34 older women were enrolled in the service with a mean age of 61.53 years. There was a significant improvement in the strength of the pelvic floor muscles, power, endurance, and fast contraction capacity after the intervention, however, it was observed a high dropout rate. Program implementation was supported by Physical Therapy teams who engaged in care coordination. The program has been maintained for over 4 years.

Conclusion

Our findings demonstrate that UI patients would benefit from physiotherapy treatment and that this intervention is feasible. This RE-AIM evaluation provides lessons learned and strategies for future adoption, implementation, and maintenance of a Physical Therapy pelvic service.

Effect of pelvic floor muscle training using mobile health applications for stress urinary incontinence in women: a systematic review

BACKGROUND

Pelvic floor muscle training (PFMT) is the first-line treatment for urinary incontinence, but adherence to PFMT is generally poor. Currently, a number of novel strategies exist to facilitate adherence of PFMT. We sought to determine effectiveness of mHealth app-based PFMT for treating stress urinary incontinence (SUI) or stress-predominant mixed urinary incontinence (MUI) in women. The primary objective was to assess the effects of mHealth app-based PFMT and usual treatment on severity of the symptom, the quality of life (QoL) of users and the patient's global impression of improvement. The secondary objective was to assess how mHealth app use affects adherence of PFMT.

METHODS

All randomized controlled trials and quasi-randomized controlled trials aimed at evaluating the effects of mHealth app-based PFMT in women with SUI or stress-predominant MUI were included. Twelve electronic databases, namely the Cochrane Library, PubMed, CINAHL, Embase, Web of science, OVID, SciELO, REHABDATA, PEDro database, Chinese CNKI and Wanfang and the Open Grey databases were used as search sources. The protocol was registered in PROSPERO (CRD 42020183515). This systematic review was developed following the PRISMA 2020 Checklist. The Cochrane Handbook for Systematic Reviews of Interventions for Randomized Controlled Trials was used to assess risk of bias in included studies. Two authors extracted the data into a standardized spreadsheet.

RESULTS

Six studies that met the eligibility criteria were included. The full sample included 439 patients with treatment via mHealth app and 442 controls of usual treatment. ICIQ-UI SF, ICIQ-VS, and QUID scores decreased after follow-up in the mHealth app and control groups in six studies. ICIQ-LUTS QoL scores decreased after follow-up in the mHealth app and control groups in three studies. In only one study, ICIQ-VS QoL scores decreased after 1 month and 2 months of follow-up in the mHealth app group, but increased abruptly after 3 months of follow-up. EQ5D-VAS scores increased in both groups in one study. The percentage of PGI-I increased in the mHealth app group in three studies after follow-up. After follow-up in three studies, BPMSES scores and self-reported adherence scores increased in the mHealth app group relative to the initial time point, but in one study, at 6 months compared with 3 months of follow-up, adherence scores decreased slightly in the mHealth app group.

CONCLUSIONS

This systematic review determined that mHealth app-based PFMT showed promise from the perspective of improving both outcomes and exercise adherence.

The influence of one-time biofeedback electromyography session on the firing order in the pelvic floor muscle contraction in pregnant woman–A randomized controlled trial

Many women are initially unable to contract the pelvic floor muscles (PFMs) properly, activating other muscle groups before, or instead of, PFM. Numerous authors have proved that biofeedback can be an ideal tool supporting learning of the PFM contraction. However, there is currently a lack of scientific data on how many biofeedback sessions are necessary in this educational process. In this study we aimed at assessing the effects of one-time electromyography (EMG) biofeedback session on the order in which PFM are activated (so called firing order) during conscious contractions in relation to selected synergistic muscles in pregnant, continent women. A randomized controlled trial was conducted in 90 healthy nulliparous women with uncomplicated pregnancies and without diagnosed urinary incontinence. We divided the participants into a biofeedback group (50) and a control group (40). They were, respectively: 30 ± 4 and 30 ± 4 years old, at their 23 ± 5 or 25 ± 7 week of gestation and presented 23 ± 5 or 24 ± 5 kg/m² BMI value (M + SD). Surface EMG with vaginal probes has been used to assess the PFM firing order in selected tasks: in five 3-s maximal contractions (quick flicks), five 10-s contractions, and in a 60-s contraction (static hold). We used the 1–5 scale, where “1” meant the best score, awarded when PFM was activated first in order. The most important finding of our study is that a single EMG biofeedback substantially improved the PFM contractions in pregnant women. First, when applying one-time biofeedback session, more women maintained correct technique or improved it in the second assessment, compared to the control group (73 vs. 65%). Secondly, using the quantitative and qualitative analysis with the Chi-square McNamara B/C test, in the biofeedback group we observed a statistically significant improvement of PFM firing order in four tasks: in the first quick flicks (p = 0.016), third quick flicks (p = 0.027), fifth quick flicks (p = 0.008), and in the first 10-s contractions (p = 0.046). In the control group we observed better outcome only in one motor task: in the fourth 10-s contraction (p = 0.009). Given the positive effects of a single session of EMG biofeedback on the firing order in the PFM contractions, it should be recommended for pregnant women without urinary incontinence to teach them how to perform PFM exercises correctly.

Patient and economic benefits of psychological support for noncompliant patients

The current paper provides an overview of treatment noncompliance at various points in the treatment pathway, especially with respect to treatment for Pelvic-floor Dysfunction (PFD). The effects of noncompliance on healthcare are considered, and examples of supporting patients psychologically to increase compliance are discussed. An outline of a method to identify costs of non-compliance, and where such costs most intensely impact the healthcare system, is provided. It is suggested that psychological support is effective in terms of increased compliance and improved healthcare economics. The model is presented for PFD, but the principles developed can be generalised to many aspects of healthcare.

The Perception of Pelvic Floor Muscle Function amongst Exercising Women Who Are Repeatedly Instructed to Contract Their Pelvic Floor Muscles

In this study, the self-perception of pelvic floor muscle (PFM) contractions amongst women receiving repeated verbal instructions during exercise classes was examined. The prevalence and severity of urinary stress incontinence were also assessed. This cross-sectional observational study included 46 women (mean age 48 (±8.6)), who regularly participated in Pilates classes where repeated instruction was given to contract PFM (“instruction group”; N = 22) or not (controls, N = 24). PFM function was evaluated using transabdominal ultrasound. Simultaneously, the participant described her personal evaluation of her PFM contraction ability. The International Consultation on Incontinence Questionnaire–Short Form was also utilized. Most women (80%) correctly contract PFM; however, 95% did not perform a voluntary contraction during leg movement, without differences observed between groups. A higher perception of PFM contraction was found in the “instruction group” when performing knee flexion towards the chest without specific verbal instruction. Women who were instructed to contract their PFM suffered less incontinence and had a lower degree of severity than the controls. Most women performing Pilates exercises correctly contracted their PFM. However, there was no PFM voluntary contraction during leg movement. Exposure to repeated verbal instructions to contract PFM, over time, might lead to an improvement in women’s perception of their ability to contract PFM. Verbal instructions for PFM contraction were found to be effective in reducing urinary incontinence.

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

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.

Conservative interventions for treating urinary incontinence in women: an Overview of Cochrane systematic reviews

BACKGROUND

Urinary incontinence (UI) is the involuntary loss of urine and can be caused by several different conditions. The common types of UI are stress (SUI), urgency (UUI) and mixed (MUI). A wide range of interventions can be delivered to reduce the symptoms of UI in women. Conservative interventions are generally recommended as the first line of treatment.

OBJECTIVES

To summarise Cochrane Reviews that assessed the effects of conservative interventions for treating UI in women.

METHODS

We searched the Cochrane Library to January 2021 (CDSR; 2021, Issue 1) and included any Cochrane Review that included studies with women aged 18 years or older with a clinical diagnosis of SUI, UUI or MUI, and investigating a conservative intervention aimed at improving or curing UI. We included reviews that compared a conservative intervention with 'control' (which included placebo, no treatment or usual care), another conservative intervention or another active, but non-conservative, intervention. A stakeholder group informed the selection and synthesis of evidence. Two overview authors independently applied the inclusion criteria, extracted data and judged review quality, resolving disagreements through discussion. Primary outcomes of interest were patient-reported cure or improvement and condition-specific quality of life. We judged the risk of bias in included reviews using the ROBIS tool. We judged the certainty of evidence within the reviews based on the GRADE approach. Evidence relating to SUI, UUI or all types of UI combined (AUI) were synthesised separately. The AUI group included evidence relating to participants with MUI, as well as from studies that combined women with different diagnoses (i.e. SUI, UUI and MUI) and studies in which the type of UI was unclear.

MAIN RESULTS

We included 29 relevant Cochrane Reviews. Seven focused on physical therapies; five on education, behavioural and lifestyle advice; one on mechanical devices; one on acupuncture and one on yoga. Fourteen focused on non-conservative interventions but had a comparison with a conservative intervention. No reviews synthesised evidence relating to psychological therapies. There were 112 unique trials (including 8975 women) that had primary outcome data included in at least one analysis. Stress urinary incontinence (14 reviews) Conservative intervention versus control: there was moderate or high certainty evidence that pelvic floor muscle training (PFMT), PFMT plus biofeedback and cones were more beneficial than control for curing or improving UI. PFMT and intravaginal devices improved quality of life compared to control. One conservative intervention versus another conservative intervention: for cure and improvement of UI, there was moderate or high certainty evidence that: continence pessary plus PFMT was more beneficial than continence pessary alone; PFMT plus educational intervention was more beneficial than cones; more-intensive PFMT was more beneficial than less-intensive PFMT; and PFMT plus an adherence strategy was more beneficial than PFMT alone. There was no moderate or high certainty evidence for quality of life. Urgency urinary incontinence (five reviews) Conservative intervention versus control: there was moderate to high-certainty evidence demonstrating that PFMT plus feedback, PFMT plus biofeedback, electrical stimulation and bladder training were more beneficial than control for curing or improving UI. Women using electrical stimulation plus PFMT had higher quality of life than women in the control group. One conservative intervention versus another conservative intervention: for cure or improvement, there was moderate certainty evidence that electrical stimulation was more effective than laseropuncture. There was high or moderate certainty evidence that PFMT resulted in higher quality of life than electrical stimulation and electrical stimulation plus PFMT resulted in better cure or improvement and higher quality of life than PFMT alone. All types of urinary incontinence (13 reviews) Conservative intervention versus control: there was moderate to high certainty evidence of better cure or improvement with PFMT, electrical stimulation, weight loss and cones compared to control. There was moderate certainty evidence of improved quality of life with PFMT compared to control. One conservative intervention versus another conservative intervention: there was moderate or high certainty evidence of better cure or improvement for PFMT with bladder training than bladder training alone. Likewise, PFMT with more individual health professional supervision was more effective than less contact/supervision and more-intensive PFMT was more beneficial than less-intensive PFMT. There was moderate certainty evidence that PFMT plus bladder training resulted in higher quality of life than bladder training alone.

AUTHORS' CONCLUSIONS

There is high certainty that PFMT is more beneficial than control for all types of UI for outcomes of cure or improvement and quality of life. We are moderately certain that, if PFMT is more intense, more frequent, with individual supervision, with/without combined with behavioural interventions with/without an adherence strategy, effectiveness is improved. We are highly certain that, for cure or improvement, cones are more beneficial than control (but not PFMT) for women with SUI, electrical stimulation is beneficial for women with UUI, and weight loss results in more cure and improvement than control for women with AUI. Most evidence within the included Cochrane Reviews is of low certainty. It is important that future new and updated Cochrane Reviews develop questions that are more clinically useful, avoid multiple overlapping reviews and consult women with UI to further identify outcomes of importance.

Current State of Non-surgical Devices for Female Stress Urinary Incontinence

PURPOSE OF REVIEW

The purpose of this review is to summarize and assess the current non-surgical devices for the treatment of stress urinary incontinence (SUI).

RECENT FINDINGS

Devices for SUI can generally be divided into two categories. One category is the augmentation of pelvic floor muscle training (PFMT), wherein devices such as vaginal cones, intravaginal biofeedback, and electrical or magnetic stimulation are used to strength the pelvic floor musculature, though none are more effective than traditional PFMT. The second category of devices mechanically occludes the outlet and includes incontinence pessaries, intravaginal occlusion devices, and urethral plugs and patches. While these are palliative rather than curative, they share similar rates of improvement in leakage. A number of novel devices exist for the treatment and management of SUI. Though no single device has been shown to be more effective than PFMT alone, they may be beneficial for women who have difficulty isolating their pelvic floor muscles, desire accountability, or prefer technology-based engagement. Outlet occlusion devices are less comfortable for the patient, but remain an option for women who do not desire surgery.

Faecal incontinence in adults

Faecal incontinence, which is defined by the unintentional loss of solid or liquid stool, has a worldwide prevalence of ≤7% in community-dwelling adults and can markedly impair quality of life. Nonetheless, many patients might not volunteer the symptom owing to embarrassment. Bowel disturbances, particularly diarrhoea, anal sphincter trauma (obstetrical injury or previous surgery), rectal urgency and burden of chronic illness are the main risk factors for faecal incontinence; others include neurological disorders, inflammatory bowel disease and pelvic floor anatomical disturbances. Faecal incontinence is classified by its type (urge, passive or combined), aetiology (anorectal disturbance, bowel symptoms or both) and severity, which is derived from the frequency, volume, consistency and nature (urge or passive) of stool leakage. Guided by the clinical features, diagnostic tests and therapies are implemented stepwise. When simple measures (for example, bowel modifiers such as fibre supplements, laxatives and anti-diarrhoeal agents) fail, anorectal manometry and other tests (endoanal imaging, defecography, rectal compliance and sensation, and anal neurophysiological tests) are performed as necessary. Non-surgical options (diet and lifestyle modification, behavioural measures, including biofeedback therapy, pharmacotherapy for constipation or diarrhoea, and anal or vaginal barrier devices) are often effective, especially in patients with mild faecal incontinence. Thereafter, perianal bulking agents, sacral neuromodulation and other surgeries may be considered when necessary.

Knowledge, Attitudes, and Practice of Pelvic Floor Muscle Training in People With Spinal Cord Injury: A Cross-Sectional Survey

BACKGROUND

There is emerging evidence that pelvic floor muscle training (PFMT) may be useful for treating some urogenital conditions in people with spinal cord injury (SCI). Future clinical investigations would benefit from understanding the extent to which people with SCI are aware of and practicing PFMT, and their attitude toward this therapy.

OBJECTIVE

The goal of this study was to assess the knowledge, attitudes, and practices related to PFMT among people with SCI.

METHODS

We distributed an internet survey internationally via SCI related organizations for 2 months. We used descriptive statistics to summarize each survey item, and Chi-square and Mann-Whitney U tests to explore the differences in results between sexes and level of motor-function.

RESULTS

Complete data from 153 respondents were analyzed. Sixty-two percent of respondents were female and 71% reported having complete paralysis. More than half of respondents reported being aware of PFMT (63%); more females than males reported knowledge of PFMT (p = 0.010). Females (p = 0.052) and people with partial paralysis (p = 0.008) reported a stronger belief that they would benefit from PFMT. Few people with SCI had practiced PFMT (20%), and of those who practiced, most of them had SCI resulting in partial paralysis (p = 0.023).

CONCLUSIONS

While people with SCI may be aware of and have favorable attitudes toward PFMT, few had practiced PFMT and there were notable differences in attitudes toward PFMT depending on the sex and level of motor function of the respondents.

Use of Virtual Reality-Based Therapy in Patients with Urinary Incontinence: A Systematic Review with Meta-Analysis

It is estimated that over 400 million people worldwide experience some form of urinary incontinence (UI). Pelvic floor muscle training (PFMT) is commonly used in cases of urine loss. Game therapy (GT) has been suggested as a new conservative modality for UI treatments. GT represents a form of virtual reality (VR) that allows users to interact with elements of a simulated scenario. The purpose of this review was to assess the potential of using VR-based PFMT in the treatment of UI with a particular focus on the impact of this form of therapy on the patients’ muscle function, symptoms of UI and quality of life (QoL). The following electronic databases were searched: PubMed, Embase, Cochrane Library, Scopus and Web of Science. Systematic review methods were based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Electronic medical databases were searched from inception to 28 January 2021. From a total of 38 articles, 26 were analyzed after removing duplicates, then 22 records were excluded according to inclusion criteria and 4 were assessed as full texts. Finally, 2 randomized controlled trials (RCT) with 79 patients were included. For the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the meta-analysis showed a significant difference in favor of the control condition (MD = 2.22; 95% CI 0.42, 4.01; I² = 0%). Despite the popularity of the use of VR in rehabilitation, we found a scarcity of literature evaluating the application of VR in the field of UI therapy. Only one study matched all of the criteria established. The effects of VR training improved PFM function and QoL; however, these changes were comparable to those of traditional PFMT. It is not possible to reach final conclusions from one study; thus, further development of VR interventions in the field of UI treatments are needed.

Mechanisms of pelvic floor muscle training for managing urinary incontinence in women: a scoping review

BACKGROUND

Pelvic floor muscle training is recommended as first line treatment for urinary incontinence in women based on three proposed theorized mechanisms: 'Enhanced Pelvic Floor Muscle Strength,' 'Maximized Awareness of Timing,' and 'Strengthened Core Muscles'. The purpose of this scoping review was to systematically map evidence for and against theorized mechanisms through which pelvic floor muscle training interventions work to reduce urinary incontinence in women.

METHODS

The scoping review is based upon a comprehensive search of relevant literature published from 1990 to 2020 in PubMed, CINAHL, PsycINFO, ClinialTrials.gov, reference lists from review articles, and hand searches of articles by known researchers in the field. We included English-language, peer-reviewed articles on pelvic floor muscle training as an intervention for adult women if they provided empirical evidence to testing the theorized intervention mechanisms. Two independent reviewers screened articles for inclusion and extracted data to describe details of each study (author, year, country, design, sampling), measures of pelvic floor muscle strength and urinary incontinence, statistical analysis of linkage between changes in the measures, and pelvic floor muscle training regimens. Data were summarized to facilitate the integration of diverse evidence to draw conclusions on supporting or refuting the three proposed theorized mechanisms for managing urinary incontinence in women.

RESULTS

Of the 278 articles identified with the search, 13 (4.7%) met inclusion criteria. There was weak to no evidence for the mechanism of enhanced pelvic floor muscle strength, equivocal support for maximized awareness of timing, and no evidence for strengthened core muscles.

CONCLUSIONS

This review revealed extremely limited data supporting the proposed theorized mechanisms underlying pelvic floor muscle training programs to manage urinary incontinence in women. Such evidence is needed to help women and clinicians understand how, why and when a woman benefits from pelvic floor muscle training. Future studies should specifically state and report statistical analysis that relates the theorized mechanisms to the training outcomes observed.

Comparing the efficacy of the Knack maneuver on pelvic floor muscle function and urinary symptoms using different teaching methods: a prospective, nonrandomized study

INTRODUCTION AND HYPOTHESIS

This study was aimed at comparing the efficacy of Knack maneuver training taught using different techniques on pelvic floor muscle (PFM) function, urinary symptoms, and perception of improvement in women with stress urinary incontinence (SUI).

METHODS

We conducted a prospective nonrandomized study of 46 women with SUI. Assessments included: PFM functions (secondary outcome, SO) using a Myomed 932 EMG biofeedback device, urinary incontinence symptoms using the International Consultation on Incontinence Questionnaire Urinary Incontinence-Short Form (ICIQ-SF; primary outcome), the Urogenital Distress Inventory-6 (UDI-6; SO), and the Incontinence Severity Index (ISI; SO), and perception of improvement using the Global Perceived Impact scale. The women were divided into three groups according to their preference: group 1 (Knack maneuver training with electromyography biofeedback), group 2 (Knack maneuver training with verbal instruction), and group 3 (Knack maneuver training with vaginal palpation). An education program was also given to all women individually. The training program was 1 day per week for 4 weeks.

RESULTS

There was an improvement in UDI-6, ICIQ-SF, and ISI scores in all groups (p<0.05). The maximum voluntary contraction (MVC) of the PFMs increased in group 2 (p=0.002), whereas both the MVC of PFMs and PFM contraction during Valsalva increased in group 3 (p=0.011 and p=0.042).

CONCLUSIONS

Regardless of the teaching methods, the Knack maneuver and education programs were effective on urinary symptoms in women with mild to moderate SUI. The Knack maneuver training with vaginal palpation and verbal instruction improved MVC of PFMs. All three different teaching methods might be used in SUI treatment programs.

Stress urinary incontinence and the forgotten female hormones

The use of hormones to treat stress urinary incontinence (SUI) has fallen out of favor because of concerns over safety following publication of the Women's Health Initiative study. In addition, there are data that suggest that estrogen treatment does not help SUI. As women age, the decline in androgen output mirrors the increasing prevalence of SUI implying a potential causal association. Therefore, we suggest that androgens are the 'forgotten female hormone.' Vaginal estrogens can treat pelvic floor structures without significant systemic effects; we suggest that vaginal androgens can act similarly and thereby avoid the unwanted systemic effects of androgenization in women. Based on available preclinical and clinical data, we suggest that research should investigate vaginal treatment with androgen hormones as adjunctive therapy to pelvic floor exercises for SUI. In a postmenopausal woman, this could be supplemented with estrogens if trial data warrant it.

The effect of pelvic floor muscle training on pelvic floor function and sexuality postpartum. A randomized study including 300 primiparous

PURPOSE

Although pregnancy and childbirth are physiological processes they may be associated with pelvic floor disorders. The aim of this study was to evaluate the influence of pelvic floor muscle training on postpartum pelvic floor and sexual function of primiparous.

METHODS

This is a randomized prospective study including 300 primiparous women. Due to the dropout 200 women were analyzed. Inclusion criteria were the delivery of the first, mature baby, the ability to speak and understand German. The participants were evaluated by clinical examinations and questionnaires after 6 and 12 months postpartum. After 6 months, the women were randomized in two groups. Compared to the control group the intervention groups participated in 45-min pelvic floor muscle training and pelvic floor perception once a week over 6 weeks.

RESULTS

The results of the questionnaires showed no significant differences between the groups after 12 months. A significant stronger pelvic floor muscle strength was found for the intervention group after 12 months. The improvement of the pelvic floor and sexual function over the time showed a significant improvement in both groups.

CONCLUSION

Supervised pelvic floor muscle training did not improve both the pelvic floor and the female sexual function in comparison to the control group. After 12 months, the pelvic floor and sexual function improved significant in all women.

TRIAL REGISTRATION

German Clinical Trials Register (DRKS00024725), retrospectively registrated.

Pelvic Floor Dysfunctions and Their Rehabilitation in Multiple Sclerosis

Urinary, bowel, and sexual dysfunctions are the most frequent and disabling pelvic floor (PF) disorders in patients with multiple sclerosis (MS). PF dysfunction negatively impacts the performance of daily living activities, walking, and the physical dimension of quality of life (QoL) in people with MS. Patient-reported outcomes on sphincteric functioning could be useful to detect PF disorders and their impact on patients’ lives. PF rehabilitation proposed by Kegel is based on a series of regularly repeated exercises for “the functional restoration of the perineal muscles”. Over time, various therapeutic modalities have been added to PF muscles exercises, through the application of physical or instrumental techniques, such as intravaginal neuromuscular electrical stimulation, electromyographic biofeedback, transcutaneous tibial nerve stimulation. PF rehabilitation has been applied in MS treatment, with improvements of lower urinary tract symptoms severity, QoL, level of anxiety and depression, and sexual dysfunction. This review aims to examine the different PF disorders in MS to evaluate the application of PF rehabilitation in MS and to highlight its advantages and limits, suggesting a multidisciplinary management of PF disorders, with a well-deserved space reserved for PF rehabilitation.

The effect of pelvic floor muscle training for women with pelvic organ prolapse: a meta-analysis

INTRODUCTION AND HYPOTHESIS

This study was aimed at evaluating the effect of pelvic floor muscle training (PFMT) as a conservative treatment for patients with pelvic organ prolapse (POP).

METHODS

A comprehensive search to identify eligible randomized controlled trial (RCT) studies was conducted using electronic databases including PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Embase up to 10 June 2021. Results were presented as risk ratio (RR), the weighted mean difference (WMD), with 95% confidence interval (95% CI) using the random effects model. Outcome variables were pooled using Review Manager version 5.3.

RESULTS

Thirteen studies were included. Our results demonstrated that women who received PFMT intervention had a greater improvement than controls in prolapse symptom score (POP-SS; mean difference [MD] -1.66, 95% CI -2.36 to -0.97, p < 0.00001] and POP stages (risk ration [RR] 1.51, 95% CI 1.14-2.01, p = 0.004). The number of participants who felt better after PFMT was higher (RR 1.98, 95% CI 1.21-3.24, p = 0.006). Subgroup analysis showed that the symptoms of prolapse and the degree of prolapse were improved significantly in the short term, but there was no significant difference in the long-term effect. In addition, there was no significant difference in the impact of PFMT on the elderly and the quality of life. More RCTs are needed to evaluate the effect of PFMT on the elderly and whether the quality of life can be improved.

CONCLUSIONS

We found that PFMT can improve subjective symptoms and objective POP severity. More research is needed on the long-term effect.

Effectiveness of ultrasound-guided pelvic floor muscle training in improving prolonged urinary incontinence after robot-assisted radical prostatectomy

Persistence of urinary incontinence (UI) after robot-assisted radical prostatectomy (RARP) is a bothersome problem because of its negative effect on the patient's quality of life (QOL). This study aimed to evaluate the effect of transperineal ultrasound (TPUS)-guided pelvic floor muscle training (PFMT) on prolonged UI after RARP. Thirty men with stress UI persisting for > 1 year after RARP underwent biofeedback PFMT using TPUS once every 2-3 weeks for 3 months. The frequency and duration of sustaining pelvic floor muscle (PFM) contractions were assessed using ultrasound imaging. The severity of UI and UI-related QOL were evaluated using a 24-hour pad test and the incontinence quality of life (I-QOL) questionnaire. Twenty-four men (mean age, 72.2 years) completed the TPUS-guided PFMT. The mean duration from RARP to PFMT was 1,228.9 days. The mean cumulative session and the total duration of TPUS-guided PFMT were 4.6 times and 73.3 days, respectively. Compared with the data before TPUS-guided PFMT, the frequency of PFM contractions and duration of sustaining contraction significantly improved after TPUS-guided PFMT (p < 0.05). Additionally, the total amount of urinary leakage after TPUS-guided PFMT was reduced significantly (248.6 ± 280.6 g vs. 397.0 ± 427.0 g, p = 0.024). The I-QOL score was significantly increased after TPUS-guided PFMT (72.1 ± 16.8 vs. 61.0 ± 19.0, p < 0.001). TPUS-guided PFMT may be effective in improving prolonged UI occurring > 1 year after RARP.

Should pregnant women know their individual risk of future pelvic floor dysfunction? A qualitative study

BACKGROUND

The study aimed to explore: • pregnant women's and healthcare professionals' perspectives on provision of individual risk scores for future Pelvic Floor Dysfunction (PFD), • the feasibility of providing this during routine maternity care, • actions women might take as a result of knowing their PFD risk.

METHODS

Qualitative study.

SETTING

UK NHS Health Board.

PARTICIPANTS

Pregnant women (n = 14), obstetricians (n = 6), midwives (n = 8) and physiotherapists (n = 3). A purposive sample of pregnant women and obstetric healthcare professionals were introduced to the UR-CHOICE calculator, which estimates a woman's PFD risk, and were shown examples of low, medium and high-risk women. Data were collected in 2019 by semi-structured interview and focus group and analysed using the Framework Approach.

RESULTS

Women's PFD knowledge was limited, meaning they were unlikely to raise PFD risk with healthcare professionals. Women believed it was important to know their individual PFD risk and that knowledge would motivate them to undertake preventative activities. Healthcare professionals believed it was important to discuss PFD risk, however limited time and concerns over increased caesarean section rates prevented this in all but high-risk women or those that expressed concerns.

CONCLUSION

Women want to know their PFD risk. As part of an intervention based within a pregnant woman/ maternity healthcare professional consultation, the UR-CHOICE calculator could support discussion to consider preventative PFD activities and to enable women to be more prepared should PFD occur. A randomised controlled trial is needed to test the effectiveness of an intervention which includes the UR-CHOICE calculator in reducing PFD.

The Efficacy and Mid-term Durability of Urethral Sphincter Injections of Platelet-Rich Plasma in Treatment of Female Stress Urinary Incontinence

Aims: This study investigated the therapeutic effect of repeated urethral sphincter injections of autologous platelet-rich plasma (PRP) in treatment of stress urinary incontinence (SUI) in women due to intrinsic sphincter deficiency (ISD) refractory to medical treatment or after the first anti-incontinence surgery.

Methods: Twenty-six women with SUI due to urodynamically proven ISD were prospectively enrolled. Five milliliters of PRP (2.5–5 times of the platelet concentrations in peripheral blood) were injected into the external sphincter at 5 sites, with 4 treatments at monthly interval. The primary end-point was post-treatment Global Response Assessment (GRA, scored 0–3) score after four PRP treatments. A GRA ≥ 2 was considered as a successful result. The secondary endpoints included changes in visual analog scale (VAS) of SUI and urodynamic parameters. The follow-up date was 12 months after the fourth PRP treatment.

Results: The mean age was 61.7 ± 15.3 years. The overall success rate was 50% with the post-treatment mean GRA of 1.5 ± 1.1. Complete dryness was achieved in 12 patients (46.2%) after the PRP treatment, and 7 (26.9%) kept total continence at 12 months. The mean VAS of SUI score decreased significantly from 6.4 ± 2.3 to 3.9 ± 2.3 after treatment (p < 0.001). The abdominal leak point pressure increased significantly from 117.5 ± 63.8 to 133.6 ± 61.7 cmH₂O (p = 0.045). No perioperative adverse events or severe complications occurred, except 1 (3.8%) patient reported straining to void which was self-limited.

Conclusion: Repeated urethral sphincter injections of autologous PRP are a safe procedure that provides significant reduction in the severity of female SUI and a mid-term durability, suggesting PRP treatment is effective to increase urethral sphincter resistance for female SUI.

European Association of Urology Guidelines on the Diagnosis and Management of Female Non-neurogenic Lower Urinary Tract Symptoms. Part 1: Diagnostics, Overactive Bladder, Stress Urinary Incontinence, and Mixed Urinary Incontinence

CONTEXT

Female lower urinary tract symptoms (LUTS) are a common presentation in urological practice. Thus far, only a limited number of female LUTS conditions have been included in the European Association of Urology (EAU) guidelines compendium. The new non-neurogenic female LUTS guideline expands the remit to include these symptoms and conditions.

OBJECTIVE

To summarise the diagnostic section of the non-neurogenic female LUTS guideline and the management of female overactive bladder (OAB), stress urinary incontinence (SUI), and mixed urinary incontinence (MUI).

EVIDENCE ACQUISITION

New literature searches were carried out in September 2021 and evidence synthesis was conducted using the modified GRADE criteria as outlined for all EAU guidelines. A new systematic review (SR) on OAB was carried out by the panel for the purposes of this guideline.

EVIDENCE SYNTHESIS

The important considerations for informing guideline recommendations are presented, along with a summary of all the guideline recommendations.

CONCLUSIONS

Non-neurogenic female LUTS are an important cause of urological dysfunction. Initial evaluation, diagnosis, and management should be carried out in a structured and logical fashion based on the best available evidence. This guideline serves to present this evidence to health care providers in an easily accessible and digestible format.

PATIENT SUMMARY

This report summarises the main recommendations from the European Association of Urology guideline on symptoms and diseases of the female lower urinary tract (bladder and urethra) not associated with neurological disease. We cover recommendations related to diagnosis of these conditions, as well as the treatment of overactive bladder, stress urinary incontinence, and mixed urinary incontinence.

Sexual Health Dysfunction After Radiotherapy for Gynecological Cancer: Role of Physical Rehabilitation Including Pelvic Floor Muscle Training

Introduction

The present study aims to describe: 1. How the side effects of radiotherapy (RT) could impact sexual health in women; 2. The effectiveness of physical rehabilitation including pelvic floor muscle training (PFMT) in the management of sexual dysfunction after RT.

Materials and Methods

Search keys on PubMed, Web of Science, Scopus, PEDro, and Cochrane were used to identify studies on women treated with radical or adjuvant RT and/or brachytherapy for gynecological cancers with an emphasis on vulvo-vaginal toxicities and PFMT studies on sexual dysfunction for this group of women.

Results

Regarding the first key question, we analyzed 19 studies including a total of 2,739 women who reported vaginal dryness, stenosis, and pain as the most common side effects. Reports of dosimetric risk factors and dose-effect data for vaginal and vulvar post-RT toxicities are scant. Only five studies, including three randomized controlled trials (RCTs), were found to report the effect of PFMT alone or in combination with other treatments. The results showed some evidence for the effect of training modalities including PFMT, but to date, there is insufficient evidence from high-quality studies to draw any conclusion of a possible effect.

Conclusions

Gynecological toxicities after RT are common, and their management is challenging. The few data available for a rehabilitative approach on post-actinic vulvo-vaginal side effects are encouraging. Large and well-designed RCTs with the long-term follow-up that investigate the effect of PFMT on vulvo-vaginal tissues and pelvic floor muscle function are needed to provide further guidance for clinical management.

Improvements following multimodal pelvic floor physical therapy in gynecological cancer survivors suffering from pain during sexual intercourse: Results from a one-year follow-up mixed-method study

BACKGROUND

A large proportion of gynecological cancer survivors suffer from pain during sexual intercourse, also known as dyspareunia. Following a multimodal pelvic floor physical therapy (PFPT) treatment, a reduction in pain and improvement in psychosexual outcomes were found in the short term, but no study thus far has examined whether these changes are sustained over time.

PURPOSE

To examine the improvements in pain, sexual functioning, sexual distress, body image concerns, pain anxiety, pain catastrophizing, painful intercourse self-efficacy, depressive symptoms and pelvic floor disorder symptoms in gynecological cancer survivors with dyspareunia after PFPT, and to explore women's perceptions of treatment effects at one-year follow-up.

METHODS

This mixed-method study included 31 gynecological cancer survivors affected by dyspareunia. The women completed a 12-week PFPT treatment comprising education, manual therapy and pelvic floor muscle exercises. Quantitative data were collected using validated questionnaires at baseline, post-treatment and one-year follow-up. As for qualitative data, semi-structured interviews were conducted at one-year follow-up to better understand women's perception and experience of treatment effects.

RESULTS

Significant improvements were found from baseline to one-year follow-up on all quantitative outcomes (P ≤ 0.028). Moreover, no changes were found from post-treatment to one-year follow-up, supporting that the improvements were sustained at follow-up. Qualitative data highlighted that reduction in pain, improvement in sexual functioning and reduction in urinary symptoms were the most meaningful effects perceived by participants. Women expressed that these effects resulted from positive biological, psychological and social changes attributable to multimodal PFPT. Adherence was also perceived to influence treatment outcomes.

CONCLUSIONS

Findings suggest that the short-term improvements following multimodal PFPT are sustained and meaningful for gynecological cancer survivors with dyspareunia one year after treatment.

Pelvic floor muscle exercise and training for coping with urinary incontinence

The pelvic floor consists of levator ani muscles including puborectalis, pubococcygeus and iliococcygeus muscles, and coccygeus muscles. Pelvic floor muscle exercise (PFME) is defined as exercise to improve pelvic floor muscle strength, power, endurance, relaxation, or a combination of these parameters. PFME strengthens the pelvic floor muscles to provide urethral support to prevent urine leakage and suppress urgency. This exercise has been recommended for urinary incontinence since first described by Kegel. When treating urinary incontinence, particularly stress urinary incontinence, PFME has been recommended as first-line treatment. This article provides clinical application of PFME as a behavioral therapy for urinary incontinence. Clinicians and physical therapist should understand pelvic floor muscle anatomy, evaluation, regimen, and instruct patients how to train the muscles properly.

50 years in urinary incontinence: a bibliometric analysis of the top 100 cited articles of the last 50 years

INTRODUCTION

A large body of literature has been published on urinary incontinence, ranging from medical treatment, epidemiology and surgical techniques. A bibliometric analysis is used to identify high-quality research papers using criteria such as citation rate and journal impact factor.

OBJECTIVES

To describe key themes and topics in urinary incontinence literature in the last 50 years.

METHODS

Thomson Reuters Web of Science citation indexing database was used to identify the top 100 cited articles in urinary incontinence in the last 50 years. Data sets were subdivided into manuscript type, theme, author, institution, country of origin, journal and citation rate.

RESULTS

Mean number of citations in the top 100 group for manuscripts was 676, ranging between 2444 and 306. Most cited paper was by Irwin et al.

Role of Incontinence Severity Index in Evaluating Severity and Impact of Treatment Of Stress Urinary Incontinence

Background

Stress urinary incontinence (SUI) is a common ailment in affecting quality of life. This study was performed to see role of incontinence severity index (ISI) in evaluating severity of SUI and to see the impact of treatment of SUI.

Materials and Methods

A total of 40 women with the diagnosis of SUI on history and clinical examination were enrolled. ISI was calculated on all the women before treatment. All women were treated with either conservative treatment (pelvic floor exercises, life style modification, and duloxetine therapy) (4, 10%) or Burch's colposuspension (18, 45%) or tension-free obturator tape (18, 45%) as per clinical situation after discussion with patients. ISI was again calculated 6 months after treatment.

Results

Mean age, parity, body mass index in the study were 41.60 years, 2.73, and 24.2 kg/m², respectively. All 40 (100%) patients had SUI with the mean duration of symptoms being 4.04 years. A total of 11 (27.5%) had moderate SUI (ISI 3-6), while 24 (60%) had severe SUI (ISI 8-9), while 5 (12.5%) had very severe SUI (ISI 12). Range of pretreatment ISI was 3-12 with mean being 8.8 ± 3.2. Posttreatment ISI reduced significantly with range of 1-4 and mean of 1.3 ± 0.4 (P < 0.001). The reduction was significant for all the groups, but there was no significant difference in efficacy of three treatment groups. Statistical analysis was done using SPSS IBM Version 2-1-0 using Chi-square test, Fisher's Extract test, and ANOVA test as appropriate.

Conclusion

ISI is a useful modality to evaluate the severity of SUI and to see the impact of treatment modalities on SUI.

Antenatal pelvic floor muscle training and urinary incontinence: a randomized controlled 7-year follow-up study

Introduction and hypothesis

Urinary incontinence is common postpartum. Our aims were to assess whether antenatal exercise including pelvic floor muscle training (PFMT) has long-term effects on urinary incontinence (UI) and to explore factors associated with UI 7 years postpartum.

Methods

A follow-up of a two-centre randomized controlled trial performed at St. Olavs Hospital and Stavanger University Hospital, Norway. In the original trial women were randomized to a 12-week structured exercise protocol including PFMT or standard antenatal care during pregnancy. Link to an electronic questionnaire was sent by postal mail 7 years postpartum. Prevalence of UI was assessed with Sandvik severity index and compared between groups. Factors associated with UI were studied using multivariable logistic regression analysis.

Results

The response rate was 35% (298/855). UI was reported by 78 (51%) in the intervention group and 63 (57%) in the control group (p = 0.539). In the multivariable logistic regression analyses, women with UI at inclusion had a five-fold increase in odds of UI at 7 years (OR 5.4, 95% CI 2.6, 11.5). Engaging in regular exercise was not significantly associated with UI at 7 years; however, UI was associated with lower exercise intensity (OR 2.4, 95% CI 1.2, 4.6).

Conclusions

We found no group differences of antenatal exercise including PFMT on UI after 7 years among the responders. UI in pregnancy increased the risk of long-term UI. Regular exercise was not associated with UI at 7 years; however, women with UI were more than twice as likely to exercise at lower intensity than continent women.

What Influences Women to Adhere to Pelvic Floor Exercises after Physiotherapy Treatment? A Qualitative Study for Individualized Pelvic Health Care

Conservative treatment of pelvic floor dysfunction (PFD) includes therapeutic exercise for pelvic floor muscle (PFM) training or other complementary exercise modalities, such as hypopressive exercises. However, the long-term effectiveness of the conservative treatment depends on a patient's adherence to the exercises and the integration of professional health advice into their daily life. The objective of this study was to establish the adherence experience of women with diagnosed PFD in home-based exercises after an intensive face-to-face physiotherapy treatment. A qualitative study from an interpretive paradigm was developed. Semi-structured individual and group interviews were performed 6 months after finishing individual physiotherapy treatment. The interviews were recorded, fully transcribed and analyzed thematically by creating categories. Thirty-one women were interviewed. The women reported that their adherence to home PFM exercises depended on the exercise program itself, its efficacy, their personal experiences with the exercises, intrinsic factors such as self-awareness or beliefs, and extrinsic factors, such as professional or instrumental feedback. Thus, therapeutic adherence could be more likely with effective physiotherapy programs that include mutually agreed home exercises and simple movements women can build into their daily lives. Improving awareness and knowledge of the pelvic region and the importance of PFM treatment as well as consideration for potential worsening of PFD will also encourage women to adhere to the exercises.

Treatment of urinary incontinence in women with chronic obstructive pulmonary disease-a randomised controlled study

BACKGROUND

Little is known regarding treatment of urinary incontinence (UI) in women with chronic obstructive pulmonary disease (COPD). The aim of the study was to explore the efficacy of pelvic floor muscle training (PFMT) or cough-suppression techniques (CST) on UI in women with COPD.

METHODS

A three-armed, two-centred, single-blinded, randomised controlled study was performed. Subjects were randomised to (a) PFMT for 16 weeks, (b) 2-3 educational sessions in CST, or (c) written information only. All participants completed questionnaires about UI, cough symptoms, and health status and underwent clinical examinations to evaluate the strength of the pelvic floor muscles and exercise capacity. Daily physical activity levels were measured using an activity monitor and lung function with spirometry. With a significance level of 5% and an 80% chance of detecting a significant difference between groups of 2.5 points on the ICIQ UI SF score, our sample size calculation showed that a total of 78 women, 26 in each group, was required to complete the study.

RESULTS

During the period 2016 to 2018, 95 women were invited to the study. A total of 42 were recruited, three were excluded and 10 (24%) dropped out during the follow-up period. Mean ICIQ-UI SF total baseline score was 9.6 (range: 1-17) and 7.0 (range: 0-16) at follow-up. Changes in subjective UI as measured with the ICIQ-UI SF questionnaire were seen in the PFMT group and control group, but not in the CST group.

CONCLUSION

Due to the low number of available participants and recruitment difficulties including practical issues such as travel distance, lack of interest, poor state of health, and high number of comorbidities, our results are inconclusive. However, reduced subjective UI was observed in the PFMT and control groups with a trend towards best effect in the PFMT group. Screening for UI is advisable in all women with COPD to be able to identify and treat these women to reduce symptom burden and improve quality of life. Future studies should focus on barriers to recruitment as well as randomised controlled studies with larger sample sizes.

Pelvic floor rehabilitation in the treatment of mixed urinary incontinence among women

Background

Mixed urinary incontinence (MUI) is a common underreported problem among females; it has a major effect on patients’ quality of life. Treatment may be difficult since a single modality cannot be enough to alleviate both the urge and the stress symptoms. Biofeedback-assisted pelvic floor muscle training (PFMT) has a great role in strengthening the pelvic floor muscles especially when accompanied by electrical stimulation. Neuromodulation is another safe well-tolerated method that may improve symptoms of female voiding dysfunction. There are no previous studies that assessed the efficacy of biofeedback-assisted pelvic floor muscle training versus two different types of peripheral neuromodulation which are transcutaneous posterior tibial nerve stimulation (TPTNS) and anogenital neuromodulation in the treatment of mixed urinary incontinence among women. The aim of this work is to study the effectiveness of biofeedback-assisted pelvic floor muscle training with electrostimulation versus two different methods of peripheral neuromodulation techniques in the treatment of women with MUI. Patients were subjected to history taking, assessment questionnaires (Questionnaire for female Urinary Incontinence Diagnosis (QUID), Australian Pelvic Floor Questionnaire (PFQ), and International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF)), clinical examination, and manometric pressure assessment. The patients were allocated randomly into three groups. Group I received biofeedback-assisted pelvic floor muscle training and faradic electrical stimulation, group II received posterior tibial neuromodulation, and group III received anogenital neuromodulation.

Results

The present study included 68 non-virgin female patients with mixed urinary incontinence. Significant improvement was noticed in the three studied groups on the subjective and objective levels. No statistically significant difference was reported between the studied groups following the different types of intervention.

Conclusions

Biofeedback-assisted pelvic floor muscle training with electrostimulation is as effective as anogenital neuromodulation and posterior tibial neuromodulation in the treatment of mixed urinary incontinence among females.

Pelvic floor muscle function in the standing position in women with pelvic floor dysfunction

INTRODUCTION AND HYPOTHESIS

Clinical assessment of the pelvic floor muscles (PFMs) in a standing position may provide a more valid representation of PFM function experienced by patients in daily life than assessment in the lying position. The primary aim of this study was to examine PFM function in a standing versus a lying position in parous women with any type of urinary incontinence and/or pelvic organ prolapse.

METHODS

In this exploratory cross-sectional study, participant symptom status was determined using the Australian Pelvic Floor Questionnaire. Pelvic floor muscle function was assessed in standing and lying positions with a randomised order of testing. The primary outcome measure was vaginal squeeze pressure (VSP) using intra-vaginal manometry. Secondary outcomes included vaginal resting pressure, total PFM work and digital muscle testing. The difference between PFM function in a standing position compared with a lying position was analysed using paired t test or Wilcoxon's signed rank test.

RESULTS

Vaginal squeeze pressure assessed with manometry was higher in a standing than in a lying position (p = 0.001): standing (mean [SD]) 24.90 [12.67], lying 21.15 [14.65]. In contrast, PFM strength on digital muscle testing was lower in a standing position than in a lying position.

CONCLUSIONS

This study has demonstrated that PFM function in a standing position is different from that in a lying position in women with pelvic floor dysfunction. Whether the higher VSP observed in a standing position reflects a true difference in strength between positions, or a higher pressure reading due to incorrect PFM contraction technique in a standing position is uncertain. Further research with larger cohorts and a measurement tool that can accurately distinguish a rise in intra-vaginal pressure from PFM contraction rather than increasing intra-abdominal pressure is required to confirm this difference, and the clinical significance of any difference.

Impact of urinary incontinence on quality of life in female CrossFit practitioners: A cross-sectional study

OBJECTIVE

Investigate the impact of urinary incontinence (UI) on quality of life (QoL) in female CrossFit practitioners and to verify the strategies used by them to minimize the occurrence of urine leakage. In addition, to verify whether anthropometric and clinical characteristics increase the UI impact on QoL of female CrossFit practitioners.

STUDY DESIGN

This was an online cross-sectional survey. The impact of UI on QoL was investigated by International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF). Associations between the impact of UI on QoL and the clinical (age, BMI, gestations, mode of delivery, practice of other physical activities) and the others pelvic floor dysfunctions (PFD) related independent variables were tested using logistic regression analysis.

RESULTS

A total of 828 female CrossFit practitioners answered the questionnaire and 36% reported UI symptoms. The women who obtained the highest score on the ICIQ-SF have high UI interference in QoL. Previous history of two or more gestations and sexual dysfunctions (dyspareunia or vaginismus) or pelvic organ prolapse increase 2.65 and 1.82 times the risk of female CrossFit practitioners with UI having a high impact of UI on their QoL, respectively (OR = 2.65 95% CI 1.30-5.40, p = 0.01; and OR = 1.82 95% CI 1.04-3.21, p = 0.04, respectively). The most strategies used by them to minimize the occurrence of urine leakage were emptying the bladder before training (77.5%) and use absorbent (17.8%).

CONCLUSIONS

Women who had higher scores on the ICIQ-SF reported greater impact on QoL, and the previous history of two or more gestations and sexual dysfunction/pelvic organ prolapse increase the risk of women with UI who practice CrossFit to have a greater impact on QoL. Multigravida and women with sexual dysfunction/pelvic organ prolapse who practice CrossFit could have more attention on the UI symptoms due to the high impact on their QoL.

Basic versus biofeedback-mediated intensive pelvic floor muscle training for women with urinary incontinence: the OPAL RCT

BACKGROUND

Urinary incontinence affects one in three women worldwide. Pelvic floor muscle training is an effective treatment. Electromyography biofeedback (providing visual or auditory feedback of internal muscle movement) is an adjunct that may improve outcomes.

OBJECTIVES

To determine the clinical effectiveness and cost-effectiveness of biofeedback-mediated intensive pelvic floor muscle training (biofeedback pelvic floor muscle training) compared with basic pelvic floor muscle training for treating female stress urinary incontinence or mixed urinary incontinence.

DESIGN

A multicentre, parallel-group randomised controlled trial of the clinical effectiveness and cost-effectiveness of biofeedback pelvic floor muscle training compared with basic pelvic floor muscle training, with a mixed-methods process evaluation and a longitudinal qualitative case study. Group allocation was by web-based application, with minimisation by urinary incontinence type, centre, age and baseline urinary incontinence severity. Participants, therapy providers and researchers were not blinded to group allocation. Six-month pelvic floor muscle assessments were conducted by a blinded assessor.

SETTING

This trial was set in UK community and outpatient care settings.

PARTICIPANTS

Women aged ≥ 18 years, with new stress urinary incontinence or mixed urinary incontinence. The following women were excluded: those with urgency urinary incontinence alone, those who had received formal instruction in pelvic floor muscle training in the previous year, those unable to contract their pelvic floor muscles, those pregnant or < 6 months postnatal, those with prolapse greater than stage II, those currently having treatment for pelvic cancer, those with cognitive impairment affecting capacity to give informed consent, those with neurological disease, those with a known nickel allergy or sensitivity and those currently participating in other research relating to their urinary incontinence.

INTERVENTIONS

Both groups were offered six appointments over 16 weeks to receive biofeedback pelvic floor muscle training or basic pelvic floor muscle training. Home biofeedback units were provided to the biofeedback pelvic floor muscle training group. Behaviour change techniques were built in to both interventions.

MAIN OUTCOME MEASURES

The primary outcome was urinary incontinence severity at 24 months (measured using the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form score, range 0-21, with a higher score indicating greater severity). The secondary outcomes were urinary incontinence cure/improvement, other urinary and pelvic floor symptoms, urinary incontinence-specific quality of life, self-efficacy for pelvic floor muscle training, global impression of improvement in urinary incontinence, adherence to the exercise, uptake of other urinary incontinence treatment and pelvic floor muscle function. The primary health economic outcome was incremental cost per quality-adjusted-life-year gained at 24 months.

RESULTS

A total of 300 participants were randomised per group. The primary analysis included 225 and 235 participants (biofeedback and basic pelvic floor muscle training, respectively). The mean 24-month International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form score was 8.2 (standard deviation 5.1) for biofeedback pelvic floor muscle training and 8.5 (standard deviation 4.9) for basic pelvic floor muscle training (adjusted mean difference -0.09, 95% confidence interval -0.92 to 0.75; p = 0.84). A total of 48 participants had a non-serious adverse event (34 in the biofeedback pelvic floor muscle training group and 14 in the basic pelvic floor muscle training group), of whom 23 (21 in the biofeedback pelvic floor muscle training group and 2 in the basic pelvic floor muscle training group) had an event related/possibly related to the interventions. In addition, there were eight serious adverse events (six in the biofeedback pelvic floor muscle training group and two in the basic pelvic floor muscle training group), all unrelated to the interventions. At 24 months, biofeedback pelvic floor muscle training was not significantly more expensive than basic pelvic floor muscle training, but neither was it associated with significantly more quality-adjusted life-years. The probability that biofeedback pelvic floor muscle training would be cost-effective was 48% at a £20,000 willingness to pay for a quality-adjusted life-year threshold. The process evaluation confirmed that the biofeedback pelvic floor muscle training group received an intensified intervention and both groups received basic pelvic floor muscle training core components. Women were positive about both interventions, adherence to both interventions was similar and both interventions were facilitated by desire to improve their urinary incontinence and hindered by lack of time.

LIMITATIONS

Women unable to contract their muscles were excluded, as biofeedback is recommended for these women.

CONCLUSIONS

There was no evidence of a difference between biofeedback pelvic floor muscle training and basic pelvic floor muscle training.

FUTURE WORK

Research should investigate other ways to intensify pelvic floor muscle training to improve continence outcomes.
