Pelvic floor muscle function in women with and without urinary incontinence: are strength and endurance the only relevant functions? a cross-sectional study

Technologies for Evaluation of Pelvic Floor Functionality: A Systematic Review

Pelvic floor dysfunction is a common problem in women and has a negative impact on their quality of life. The aim of this review was to provide a general overview of the current state of technology used to assess pelvic floor functionality. It also provides literature research of the physiological and anatomical factors that correlate with pelvic floor health. This systematic review was conducted according to the PRISMA guidelines. The PubMed, ScienceDirect, Cochrane Library, and IEEE databases were searched for publications on sensor technology for the assessment of pelvic floor functionality. Anatomical and physiological parameters were identified through a manual search. In the systematic review, 114 publications were included. Twelve different sensor technologies were identified. Information on the obtained parameters, sensor position, test activities, and subject characteristics was prepared in tabular form from each publication. A total of 16 anatomical and physiological parameters influencing pelvic floor health were identified in 17 published studies and ranked for their statistical significance. Taken together, this review could serve as a basis for the development of novel sensors which could allow for quantifiable prevention and diagnosis, as well as particularized documentation of rehabilitation processes related to pelvic floor dysfunctions.

Can We Improve the Technique of Pelvic Floor Muscle Exercises in Postmenopausal Women Using a Single Electromyography Biofeedback Session? An Experimental Study

Background: The aim of this study was to assess the effect of a single session of EMG biofeedback in a group of postmenopausal women on improving technique in pelvic floor muscle (PFM) contractions (exercises). Methods: Sixty-two women aged 60 to 85 years (69 ± 4; mean ± SD) participated in the study. We assessed the technique of PFM exercises via surface electromyography (EMG) using a vaginal probe. A single assessment sequence consisted of 11 exercises involving the conscious contraction of the PFM, during which the order of activation for selected muscles was determined. We then awarded scores for exercise technique on a scale from 0 to 4, where 4 represented the best technique and 0 represented no activation of PFMs. In the second assessment, we used a biofeedback method to teach PFM exercise technique. Results: In total, 32% (n = 20) of the participants were unable to correctly perform the first PFM contraction, scoring 0.9 ± 0.79. After a single EMG biofeedback session, these women received 1.7 ± 1.08 scores (p = 0.003). In the tenth exercise, there was also a statistically significant improvement between the first (baseline) and second assessment (1.7 ± 1.34 and 2.15 ± 1.09, respectively; p = 0.037). For the remaining exercises, the results were not statistically significant, but we observed a positive trend of change. Conclusions: The use of a single EMG biofeedback session is an effective method of improving technique in PFM exercises in a group of women who initially performed them incorrectly.

Pelvic floor muscle training in telerehabilitation: a systematic review and meta-analysis

PURPOSE

This systematic review aims to identify, critically appraise, and summarize current evidence regarding the feasibility and efficacy of pelvic floor muscle training in telerehabilitation.

METHODS

Three bibliographic databases, PubMed, Embase, and Scopus were searched from inception to October 1, 2023. Clinical trials assessing the feasibility and efficacy of pelvic floor muscle training in telerehabilitation were eligible for inclusion. The Physiotherapy Evidence Database scale and National Institutes of Health Study Quality Assessment Tool were used for methodological quality assessment. Study selection, data extraction, and quality assessment were completed by two independent reviewers. Meta-analyses were performed to determine the effects of pelvic floor muscle training in telerehabilitation.

RESULTS

Five randomized controlled trials and three single cohort clinical trials were included in this review. Four studies were evaluated as good quality, and four as fair. Pelvic floor telerehabilitation was well tolerated and demonstrated good patient compliance and satisfaction. Pooled analysis indicated significant effects of pelvic floor telerehabilitation on the severity of urinary incontinence with a large effect size, pelvic floor muscle strength with a large effect size, and quality of life with a medium effect size.

CONCLUSION

This systematic review demonstrates that pelvic floor muscle training in telerehabilitation is a feasible and effective approach and highlights its efficacy in patients with urinary incontinence. This review supports the application of pelvic floor muscle training in telerehabilitation and informs further clinical and research endeavors to incorporate digital health technologies in managing pelvic floor dysfunction.

Exploring transvaginal sonographic characteristics of the levator ani muscle in women with postpartum pelvic floor myofascial pain

BACKGROUND

Pelvic floor myofascial pain is one of the pelvic floor dysfunction diseases disturbing women after delivery. There is a lack of objective standardization for the diagnosis of pelvic floor myofascial pain due to the various symptoms and the dependence on the palpating evaluation. Ultrasound imaging has the advantages of safety, simplicity, economy and high resolution, which makes it an ideal tool for the assistant diagnosis of pelvic floor myofascial pain and evaluation after treatment.

METHODS

This is a retrospective case-control study including women accepting evaluation of pelvic floor function at 6 weeks to 1 year postpartum. They were divided into pelvic floor myofascial pain group and normal control group. A BCL 10-5 biplane transducer was applied to observed their puborectalis. The length, minimum width, area, deficiency, deficiency length, deficiency width, deficiency area, rate of deficiency area, local thickening,angle between the tendinous arch of levator ani muscle and puborectalis of corresponding puborectalis in different groups were observed and measured.

RESULTS

A total of 220 postpartum women participated in the study, with 77 in the pelvic floor myofascial pain group and 143 in the normal control group. The Intraclass correlation coefficient value was over 0.750, and Kappa ranged from 0.600 to 0.800. puborectalis deficiency (adjusted odds ratio = 11.625, 95% confidence interval = 4.557-29.658) and focal thickening (adjusted odds ratio = 16.891, 95% confidence interval = 1.819-156.805) were significantly associated with higher odds of having postpartum pelvic floor myofascial pain. Grayscale or the angle between the arch tendineus levator ani and puborectalis measurements on the pain side tended to be smaller than on the non-pain side in patients with unilateral puborectalis or iliococcygeus pain (P < 0.05).

CONCLUSIONS

This study demonstrated that transvaginal ultrasound was a potentially efficient technique for evaluating postpartum pelvic floor myofascial pain due to its ability to assess various sonographic characteristics of the levator ani muscles.

Assessment of Involuntary PFM Contractions in Comparison with Existing Literature and IUGA/ICS Terminology Reports

INTRODUCTION AND HYPOTHESIS

Involuntary pelvic floor muscle (PFM) contractions are thought to occur during an increase in intra-abdominal pressure (IAP). Although no studies have assessed their presence in women with normal pelvic floor (PF) function, existing literature links the absence of involuntary PFM contractions to various PF dysfunctions. This study rectifies this lacuna by evaluating involuntary PFM contractions during IAP in healthy nulliparous women with no PF dysfunction, using visual observation and vaginal palpation. Results were compared with the literature and the IUGA/ICS Terminology Reports.

METHODS

Nulliparous (n=149) women performed three sets of three maximal coughs. Visual observation and vaginal palpation were conducted in the standing and supine positions. The women were not instructed to contract their PFMs. Occurrence rates were calculated for each assessment method and position; differences between positions were analyzed using the Chi-squared test.

RESULTS

Rates of occurrence of involuntary PFM contraction were low across both assessments and positions (5-17%). Significant differences were found between standing (5%) and supine (15%) positions for visual observation, but not vaginal palpation (15%, 17% respectively). Occurrence rates also differed compared with the literature and terminology reports.

CONCLUSIONS

Contrary to clinical expectations, rates of occurrence of involuntary PFM contraction among our cohort of nulliparous women were extremely low. Digital palpation results showed high agreement with the terminology reports, but only partial agreement was observed for the visual observation results. Our study underscores the need for more research aimed at defining normal involuntary PF functions, a review of our understanding of involuntary PFM contractions, and better standardized guidelines for involuntary PFM assessment methods.

Pelvic Pain of Myofascial Origin in Women: Correlation with Lower Urinary Tract Symptoms

Introduction

Women with lower urinary tract symptoms (LUTS) and high-tone pelvic floor often experience pain and have positive trigger points upon pelvic floor examination. However, the correlation of these findings has not yet been systematically examined and sufficiently understood. The aim of this cross-sectional study is to examine the correlation of pelvic myofascial pain with LUTS and pelvic floor tone.

Materials and Methods

All participants filled a standardized pelvic floor questionnaire to assess LUTS, which consists of a total of 43 questions regarding bladder, bowel, and sexual function as well as prolapse symptoms. Myofascial trigger points in different muscle groups including pubococcygeus, iliococcygeus, and obturator as well as pelvic floor muscle tone were assessed using a standardized digital examination technique.

Results

110 women were included in the study. There was a significant correlation between pain in various muscle groups and LUTS as well as high-tone pelvic floor muscle. A significant correlation could also be found between high pelvic floor muscle tone and the overall questionnaire score (p < 0.001) as well as the bladder function score (p < 0.001) and various pain scores of the different groups. Individuals with high-tone pelvic floor were more likely to have more LUTS and higher pain scores.

Conclusions

The existence of myofascial pelvic floor trigger points and high pelvic floor muscle tone seem to be reflective of pelvic floor symptoms, as assessed with a standardized pelvic floor questionnaire.

Do pelvic floor muscle function parameters differ in women according to continence status? A systematic review

BACKGROUND

Current literature highlights the difficulty in identifying which pelvic floor muscle (PFM) functions are correlated with urinary incontinence (UI).

AIM

In this study, we compared parameters of PFM function (strength, endurance, tone, control, reaction, and/or coordination) according to continence status in women (presence or absence, type and/or severity of urinary incontinence).

EVIDENCE ACQUISITION

A systematic review was conducted following the 2020 PRISMA guidelines. Three databases (Pubmed, Web of Science, and LiSSa) were searched from inception to December 31, 2021. Assessment of risk of bias was performed using the Joanna Briggs Institute critical appraisal checklist.

EVIDENCE SYNTHESIS

The initial research yielded 4733 studies. Forty-two studies met the inclusion criteria, including 4015 participants. No statistical association was found between PFM function and the presence or absence of UI, the different type of UI or the different levels of severity of UI. The heterogeneity in methodologies and analyzes of the results only with the P-value are important limitations of this review.

CONCLUSION

It appears that muscle function is not always associated with presence or absence of UI. No association is found between PFM function and type or severity of UI. These results reinforce the need to carry out a bio-psycho-social evaluation of UI that does not only focus on PFM functions. As such, the results reported herein can be considered a resource for more specific research.

The effects of one-time soft tissue therapy on pelvic floor muscle electromyographic signals in women with urinary incontinence: A randomized intervention trial

AIMS

To investigate the effects of one-time soft tissue therapy (STT) on pelvic floor muscle (PFM) electromyographic signals in women with stress and/or mixed urinary incontinence.

METHODS

An intervention study conducted with 63 women with stress and/or mixed urinary incontinence. Participants were randomly assigned to either the one-time STT group (experimental group) or the control group. The same teaching model for voluntary contraction and relaxation of the PFM was used for all participants. Electromyographic signals from the PFM during functional tasks were the primary clinical outcome measures at baseline and immediately after the intervention. Electromyographic signals were analyzed using root mean square amplitude.

RESULTS

There was no significant difference between groups in electromyographic PFM signals in prebaseline rest (mean difference: -0.146 [95% confidence interval (CI): -0.44 to 0.148; p = 0.470]), phasic contractions (mean difference: 0.807 [95% CI: 0.123-1.491; p = 0.459]), tonic contractions (mean difference: 1.06 [95% CI: 0.255-1.865; p = 0.302]), endurance contractions (mean difference: 0.896 [95% CI: 0.057-1.735; p = 0.352]) and postbaseline rest (mean difference: -0.123 [95% CI: -0.406 to 0.16; p = 0.591]) immediately after the one-time STT intervention.

CONCLUSION

A one-time STT intervention does not appear to effectively alter electromyographic signal of the PFM in women with urinary incontinence. Due to the limitations of the study, further research is needed to confirm these results.

Pelvic floor muscle strength and influencing factors based on vaginal manometry among healthy women at different life stages: A multicentre cross-sectional study

OBJECTIVE

To assess pelvic floor muscle (PFM) strength and influencing factors among healthy women at different life stages.

DESIGN

Multicentre cross-sectional study.

SETTING

Fourteen hospitals in China.

POPULATION

A total of 5040 healthy women allocated to the following groups (with 1680 women per group): premenopausal nulliparous, premenopausal parous and postmenopausal.

METHODS

The PFM strength was evaluated by vaginal manometry. Multivariate logistic regression was used to determine the influencing factors for low PFM strength.

MAIN OUTCOME MEASURES

Maximum voluntary contraction pressure (MVCP).

RESULTS

The median MVCP values were 36, 35 and 35 cmH2 O in premenopausal nulliparous (aged 19-51 years), premenopausal parous (aged 22-61 years), and postmenopausal (aged 40-86 years) women, respectively. In the premenopausal nulliparous group, physical work (odds ratio, OR 2.05) was the risk factor for low PFM strength, which may be related to the chronic increased abdominal pressure caused by physical work. In the premenopausal parous group, the number of vaginal deliveries (OR 1.28) and diabetes (OR 2.70) were risk factors for low PFM strength, whereas sexual intercourse (<2 times per week vs. none, OR 0.55; ≥2 times per week vs. none, OR 0.56) and PFM exercise (OR 0.50) may have protective effects. In the postmenopausal group, the number of vaginal deliveries (OR 1.32) and family history of pelvic organ prolapse (POP) (OR 1.83) were risk factors for low PFM strength.

CONCLUSIONS

Physical work, vaginal delivery, diabetes and a family history of POP are all risk factors for low PFM strength, whereas PFM exercises and sexual life can have a protective effect. The importance of these factors varies at different stages of a woman's life.

What more comprehensive physiotherapy techniques than pelvic floor muscles training should be investigated in the context of post-prostatectomy? A narrative review

BACKGROUND

In a previous article, we have underlined the emerging level of evidence for the effectiveness of a more comprehensive functional physical therapy than solely pelvic floor muscles training (PFMT) for men after radical prostatectomy (RP). More and more authors suggest that physiotherapy programs should not focus only on the side effect of continence, but more generally on the interaction of continence disorders with all other side effects related to patient's physical and emotional functioning.

RESEARCH QUESTION

The aims of this narrative review are to highlight rehabilitation approaches unrelated to analytical PFMT that would seem relevant to consider in the future for post-RP men.

METHOD

Our narrative review sought to map the body of literature relevant to the primary objective (non-PFMT), supplementing the data from our previous review with additional recent articles that were not eligible due to not meeting the inclusion criteria for a systematic review.

RESULTS

After full text screening, 13 interventional studies have been selected. Intervention strategies were based on five major type of exercises: flexibility, synergism & co-activation, coordination & movement control, strength & endurance, aerobic & games therapy. Most of the studies of this narrative review focused on synergies, co-activations and movement control techniques that emphasized the deep abdominal muscles and PFMs reflexive activation. The wide variety of countries represented in the 13 studies with consistent results point to the potential effectiveness and replicability across various socio-cultural, ethnical, or religious contexts.

CONCLUSION

We found 13 studies from 9 different countries that provide a more complete rehabilitation approach than PFMT alone in men post-RP. Intervention strategies were built around five main types of exercises, with the majority of them emphasizing synergies, co-activations, and movement control techniques. In light of these data, we hope that future research will enable us to offer the most relevant and patient-centered physiotherapy treatment.

Sensory and muscular functions of the pelvic floor in women with endometriosis - cross-sectional study

PURPOSE

The aim of this study was to analyze the sensory and muscle functions of the pelvic floor in women with endometriosis, trying to improve overall knowledge/findings regarding pelvic floor muscle functions in patients with endometriosis.

METHODS

Sample size calculated as 92 patients with endometriosis, aged between 18 and 45 years, not virgin, without other causes of pain and could not be pregnant. Patients underwent the Pelvic Floor Sensorial and Muscle Function Exam (EFSMAP). Descriptive data were recorded with mean and standard deviation, median (range), and absolute and relative frequency. The Kolmogorov-Smirnov test was used to observe the normality of quantitative variables. The significance level adopted for this study was 5%.

RESULTS

Of 92 women assessed, 93.3% had pain and 75% had increased tone in the levator ani muscle; 50.4% had impaired pelvic floor relaxation with median strength of 3 by the Oxford scale and endurance of 2 s.

CONCLUSIONS

The patients had a high prevalence of pain and dysfunction of the pelvic floor muscles, such as low muscle endurance and difficulty to relax. It shows that these patients should be referred to a pelvic floor physiotherapist, as soon as they have the diagnosis of endometriosis, to be assessed to prevent and/or treat pelvic floor impairments.

The effect of an abdominopelvic exercise program alone VS in addition to postural instructions on pelvic floor muscle function in climacteric women with stress urinary incontinence. A randomized controlled trial

INTRODUCTION

Scarce literature exists regarding the influence of posture-based interventions for the treatment of stress urinary incontinence (SUI).

OBJECTIVE

The aim of this randomized controlled trial with two parallel groups was to investigate whether the addition of postural instructions to a 12-week abdominopelvic exercise program is superior to an abdominopelvic exercise program alone, in terms of PFMs function and symptoms in climacteric women with SUI.

METHODS

Climacteric women aged between 40-75 years old who presented with SUI were included in this parallel study (NCT03727945). Two randomized groups performing one 40-minutes session per week for 12-weeks were compared: one performing an abdominopelvic exercise program (AEP) and a second one performing the same intervention with the addition of postural instructions (AEPPI). PFMs electromyographical (EMG) activity and strength (Oxford Grading Scale) were quantified during a maximal voluntary contraction. SUI symptoms were assessed using a 3-day bladder diary. These outcomes were collected at baseline, immediately after intervention, and 3-months after the intervention.

RESULTS

A total of 47 women were included in the study (AEP [n = 23], AEPPI [n = 24]). Between-group analysis showed significant differences for post-intervention EMG and strength values, showing higher values for the AEPPI compared to the AEP group. At 3-months follow-up, statistically significant differences were only obtained in strength, with higher values in the AEPPI group. No significant differences were obtained in terms of UI symptoms.

CONCLUSION

A 12-session abdominopelvic exercise program supplemented with postural instructions is superior to an abdominopelvic exercise program alone in terms of PFMs function in women with SUI.

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.

Strength and Bioelectrical Activity of the Pelvic Floor Muscles and Sexual Function in Women with and without Stress Urinary Incontinence: An Observational Cross-Sectional Study

Stress urinary incontinence (SUI) results from an increase in intravesical pressure, which exceeds the pressure at which the urethra remains closed. Symptoms cause social and sexual intercourse discomfort directly or indirectly, which affect health-related quality of life and are associated with pelvic floor muscle (PFM) dysfunction. We aimed to verify the variation in strength and PFM bioelectrical activity and sexual function in women with SUI. Additionally, we analyzed the impact of this dysfunction on quality of life. This was an observational cross-sectional study. Women aged 25−55 years with frequent sexual intercourse were included. Women with SUI were included in a study group (G2, n = 17), and those without any type of incontinence were included in a control group (G1, n = 16). Primary outcomes were level of strength and PFM bioelectrical activity and sexual function as determinants of worse SUI in the control group. Secondary outcomes were associated between the primary outcomes and severity of urinary loss, impact on daily life, and quality of life in women with SUI. In the domains evaluated in the Female Sexual Function Index (FSFI), only sexual desire was lower in women with SUI (G2) than in the controls (p = 0.033). During analysis of G1 variables, a positive and moderate correlation was observed between power/myoeletric activation and maximum voluntary contraction (MVC) (p < 0.01), peak (p < 0.01), and mean amplitudes (p = 0.017). There was a high positive correlation between sexual arousal and other variables, including vaginal lubrication, sexual orgasm, and total FSFI value (p < 0.001 for all analyses). During evaluation of G2 variables, the MVC was positively correlated with the peak and mean amplitudes (p < 0.0001). Additionally, there was a high and positive correlation between the mean amplitudes (%MVC) and personal relationships (KHQ) (p = 0.001); the same was observed between the total (ICIQ) and activities of daily living (ICIQ) (p < 0.0001). Therefore, women with SUI presented with lower sexual desire and bioelectric activity but were not related to PFM strength. Additionally, the domains of sexual function and certain variables of quality of life are aggravated by SUI.

The influence of the menstrual cup on female pelvic floor muscles variables: a prospective case series

The aim was to assess and report the effects of menstrual cup on pelvic floor muscles (PFM) function and tone, as well as check the acceptability after a period of three menstrual cycles in healthy young women. The data collected in assessments and reassessments included the International Consultation on Incontinence Questionnaire - Vaginal Symptoms (ICIQ-VS) questionnaire, evaluation of PFM function through PERFECT Scheme, PFM muscle tone, and PFM manometry (Peritron 9300®). A diary regarding the overall colletor acceptability and satisfaction was collected. Ten healthy young women completed the study. There was an improvement in the mean values of maximal voluntary contraction (MVC) (p = 0.032), a decrease in the vaginal resting pressure (VRP) (p = 0.05), and an increase in the number of repetitions of sustained muscle contractions (p = 0.042). Seven women reported some discomfort while using the vaginal cup only in the first cycle while three revealed discomfort during the whole experiment. This study provides preliminary case-based evidence that the use of the vaginal cup for a period of three menstrual cycles changes the VRP, MVC, and PFM tone, as well as improves the repetitions of PFM assessed by digital palpation. Moreover, the women reported the use of vaginal cup as a positive experience.

Objetivo:

Investigar la prevalencia de la incontinencia urinaria (IU) y sus factores asociados en estudiantes universitarias del interior del estado brasileño del Amazonas.

Método:

Estudio transversal, observacional, analítico y cuantitativo. La muestra de conveniencia fue compuesta por 72 estudiantes universitarias de entre 18 y 30 años. Un cuestionario sobre datos sociodemográficos y de salud fue aplicado. La prevalencia y caracterización de las pérdidas urinarias fueron obtenidas por el International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), en su versión adaptada y validada para Brasil. Los datos fueron analizados por estadísticas descriptivas e inferenciales. Se emplearon las pruebas Wilcoxon-Mann-Whitney, Chi-cuadrado de Pearson y Exacto de Fisher, además de regresión logística (intervalo de confianza: 95% p<0,05).

Resultados:

La prevalencia de IU fue de 36,11% (26/72 estudiantes), predominantemente (80,77%) de urgencia (IUU). La edad difirió (p=0,031) entre los grupos de mujeres continentes (promedio=22,72. Desviación estándar (DE)=2,93 años) e incontinentes (promedio=21,23. DE=2,72 años). La situación predominante de pérdida fue “antes de llegar al baño” (30,77%) y el impacto de la IU sobre las actividades diarias fue considerado bajo. En el modelo de regresión logística, la edad fue un factor asociado a la presencia de IU (odds ratio (0R)=0,68; p=0,006).

Improving the Technique of Pelvic Floor Muscle Contraction in Active Nulliparous Women Attending a Structured High-Low Impact Aerobics Program-A Randomized Control Trial

Learning the correct technique of performing pelvic floor muscle (PFM) exercises is a very important factor influencing the effectiveness of this muscle group training. Correctly performed PFM contractions are involved in the urinary continence mechanism. In this study, we tested the hypothesis that a six-week high-low impact aerobics program, supported by one EMG biofeedback session and pelvic floor muscle training, improves the technique of PFM contraction. Participants were 42 active nulliparous women (age 22 ± 2 years, mean ± SD), randomly allocated into intervention (n = 18) and control (n = 24) groups. We analyzed the technique of PFM contractions, taking into account the order in which selected muscle groups were activated, so called 'firing order'. In both groups, we assessed the PFM contraction technique using surface electromyography (sEMG) and intravaginal probes, before and after six weeks of intervention. The intervention group received one biofeedback session on how to properly contract PFM and afterwards participated in a high-low impact aerobics program supplemented by PFM training. The control group did not receive any intervention. In the pre-test, 67% of the intervention group activated PFM first in order in short, quick contractions. After six weeks of training, this task was correctly performed by 100% of this group (p = 0.04). The proper performance of PFM short contraction in the control group was 75% and 67%, before and after intervention, respectively. In the intervention group we also observed statistically significant improvement in the PFM contraction technique in 10-s contractions. The presented intervention was beneficial for the improvement of PFM contraction. High-low impact aerobics, supplemented by one EMG biofeedback session and pelvic floor muscle training can be recommended for active nulliparous women.

Urinary Incontinence in Physically Active Older Women of Northeast Brazil

Low- and moderate-impact physical activity (PA) is associated with the prevention of urinary incontinence (UI). The objective of the cross-sectional study presented herein is to analyze the factors associated with UI in physically older active women who participate in senior community groups. The variable UI was measured by the International Consultation Incontinence Questionnaire Short Form (ICIQ-SF). Socioeconomic variables were also collected, along with data on life habits and clinical history. The multivariate analysis employed Poisson's Regression with robust variance for factors associated with UI. Of the 106 participants evaluated, 54.7% presented UI, of which stress incontinence was more frequent, with 40.6%. UI presented a statistically significant association with dizziness/loss of balance during Activities of Daily Living (ADL) (prevalence ratio-PR 1.48; 95% CI 1.06-2.07) and nocturia (PR 1.63; 95% CI 1.05-2.55). Despite PA being a protection factor, UI presented an elevated prevalence in the older population, and therefore, other biological, social, and cultural aspects could also contribute to the occurrence of UI in this age group. Moreover, physically active older women with UI presented nocturia and dizziness/loss of balance during ADL, regardless of education levels and the number of births. These findings can help improve multi-professional programs aimed at promoting, preventing, and managing UI in the public.

Avaliação da função dos músculos do assoalho pélvico e incontinência urinária em universitárias: um estudo transversal

RESUMO O objetivo deste estudo foi avaliar a função e pressão de contração dos Músculos do Assoalho Pélvico (MAP) e a prevalência de Incontinência Urinária (IU) em universitárias. Realizou-se um estudo transversal, com universitárias entre 18 e 35 anos, nulíparas, que já tiveram relação sexual e que nunca realizaram tratamento fisioterapêutico para Disfunções dos Músculos do Assoalho Pélvico (DMAP). Todas as voluntárias realizaram a anamnese, responderam aos questionários international consultation on incontinence questionnaire - Short Form (ICIQ-SF) e incontinence severity index questionaire (ISI-Q), e realizaram avaliação da função e manometria dos MAP. Foi utilizado o teste de Shapiro-Wilk e os valores da amostra são expressos em medianas, intervalos interquartílicos, frequências absolutas e relativas. Foram avaliadas 35 mulheres, das quais 65,72% apresentaram tônus normal, mas apenas 5,71% realizavam a contração adequada dos MAP, com medianas baixas para todas as etapas do PERFECT e na manometria dos MAP. A prevalência de IU foi 57,14%, sendo a Incontinência Urinária de Urgência (IUU) a queixa mais prevalente (50%) e com severidade moderada (55%). Este estudo permitiu identificar déficit na função dos MAP e altos índices de IU em universitárias, demostrando a importância de conscientizar esse público sobre essa DMAP.

Association of pelvic floor function with postoperative urinary incontinence in cervical cancer patients after the radical hysterectomy

AIMS

To assess the pelvic floor function in cervical cancer patients after radical hysterectomy and its relationship with urinary incontinence (UI).

METHODS

Cervical cancer patients who underwent radical hysterectomy were recruited from 18 hospitals in China from January 2012 to March 2015. Pelvic floor examinations were conducted by measuring the pelvic floor muscle strength, fatigue of pelvic floor muscle fatigue, dynamic pressure of vaginal, nerve injury, A3 feedback, muscle potential, static tension, and dynamic tension. Postoperative urinary incontinence (UI) was identified using the International Consultation on Incontinence Questionnaire. Multivariable logistic regression analysis was used to assess the association of pelvic floor function examination results with postoperative UI.

RESULTS

Totally 169 patients were included in this study. The prevalence of UI was 39.6% (67/169). The proportion of abnormal fatigue of Type I muscle (64% vs. 36%, p = .04) and abnormal A3 feedback (53.9% vs. 46.1%, p = .03) were higher among patients with postoperative UI compared to those without UI. In the multivariable analysis, abnormal fatigue of Type I muscle (odds ratio [OR] = 3.73, 95% confidence interval [CI]: 1.42-9.84), abnormal A3 feedback (OR = 2.40, 95% CI: 1.04-5.51), and length of resected vagina > 3 cm (OR = 3.44, 95% CI: 1.27-9.31) were associated with postoperative UI. Compared to laparoscopy, laparotomy was less likely to cause postoperative UI (OR = 0.12, 95% CI:0.04-0.33).

CONCLUSIONS

The abnormal function of the pelvic floor muscle is related to postoperative UI. Early assessment among these patients is needed to prevent the development of pelvic floor disorder postoperatively.

The Rolf Method of Structural Integration and Pelvic Floor Muscle Facilitation: Preliminary Results of a Randomized, Interventional Study

The management of pelvic floor dysfunctions might need to be based on a comprehensive neuro-musculoskeletal therapy such as The Rolf Method of Structural Integration (SI). The aim of the study was to evaluate the pelvic floor muscle (PFM) after the tenth session of SI by using surface electromyography (sEMG). This was a randomized, interventional study. Thirty-three healthy women were randomly assigned to the experimental (SI) or control group. The outcome measures included PFM bioelectrical activity, assessed using sEMG and endovaginal probes. An intervention in the SI group included 60 min of SI once a week, and teaching on how to contract and relax PFMs; in the control group, only the teaching was carried out. In the SI group, a significant difference was found between the PFM sEMG activity during “pre-baseline rest” (p < 0.014) and that during “rest after tonic contraction” (p = 0.021) in the supine position, as were significant increases in “phasic contraction” in the standing position (p = 0.014). In the intergroup comparison, higher PFM sEMG activity after the intervention “phasic contraction” (p = 0.037) and “pre-baseline rest” (p = 0.028) was observed in the SI group. The SI intervention significantly changes some functional bioelectrical activity of PFMs, providing a basis for further research on a new approach to PFM facilitation, particularly in clinical populations.

Urinary Incontinence in Women: Modern Methods of Physiotherapy as a Support for Surgical Treatment or Independent Therapy

Urinary incontinence (UI) is a common health problem affecting quality of life of nearly 420 million people, both women and men. Pelvic floor muscle (PFM) training and other physiotherapy techniques play an important role in non-surgical UI treatment, but their therapeutic effectiveness is limited to slight or moderate severity of UI. Higher UI severity requires surgical procedures with pre- and post-operative physiotherapy. Given that nearly 30%-40% of women without dysfunction and about 70% with pelvic floor dysfunction are unable to perform a correct PFM contraction, therefore, it is particularly important to implement physiotherapeutic techniques aimed at early activation of PFM. Presently, UI physiotherapy focuses primarily on PFM therapy and its proper cooperation with synergistic muscles, the respiratory diaphragm, and correction of improper everyday habits for better pelvic organ support and continence. The purpose of this work is a systematic review showing the possibilities of using physiotherapeutic techniques in the treatment of UI in women with attention to the techniques of PFM activation. Evidence of the effectiveness of well-known (e.g., PFM training, biofeedback, and electrostimulation) and less-known (e.g., magnetostimulation, vibration training) techniques will be presented here regarding the treatment of symptoms of urinary incontinence in women.
