Relationship between female sexual function, vaginal volume, vaginal resting tone, and pelvic floor muscle strength in women with stress urinary incontinence.

Vaginal morphology and pelvic floor muscle (PFM) strength may influence sexual stimulation, sensation, and orgasmic response. This study aimed to determine the relationship between female sexual function and PFM strength and vaginal morphology (represented by vaginal resting tone and vaginal volume) in women with stress urinary incontinence (SUI). Forty-two subjects with SUI were recruited for the study. Female sexual function was measured using the female sexual function index (FSFI) questionnaire. PFM strength was measured by digital palpation. Vaginal resting tone (mmHg) and vaginal volume (mL) were measured using a perineometer. The significance of the correlations between female sexual function and PFM function and hip muscle strength was assessed using Pearson's correlation coefficients. If a significant correlation between vaginal morphology and FSFI score was confirmed using Pearson's correlation, the cutoff value was confirmed through a decision tree. PFM strength was significantly correlated with desire (r=0.397), arousal (r=0.388), satisfaction (r=0.326), and total (r=0.315) FSFI scores. Vaginal resting tone (r=-0.432) and vaginal volume (r=0.332) were significantly correlated with the FSFI pain score. The cutoff point of vaginal resting tone for the presence of pain-related sexual dysfunction was >15.2 mmHg. PFM strength training should be the first strategy to improve female sexual function. Additionally, because of the relationship between vaginal morphology and pain-related sexual dysfunction, surgical procedures to achieve vaginal rejuvenation should be carefully considered.

Effects of Different Delivery Methods on The Functional Status of The Postpartum Pelvic Floor and Guidance on Pelvic Floor Rehabilitation Training

Objective: This study is to investigate the effects of normal and cesarean delivery on the pelvic floor function of pregnant women in the early postpartum period. Methods: 277 pregnant women who delivered in our hospital were divided into two groups: normal delivery and cesarean delivery, and pelvic floor muscle function testing was performed at 42 d after delivery to compare the functional status of the pelvic floor in the two groups. Results: The overall score of the cesarean delivery group was higher than that of the normal delivery group; among the indicators, the incidence of abnormal pelvic floor muscles in the pre and post resting stages was higher in the cesarean delivery group than in the normal delivery group, and the incidence of abnormalities in the fast and slow muscle stages and the endurance test stage was lower than that in the normal delivery group, and the differences were statistically significant (p<0.05). Conclusion: Although cesarean delivery could reduce the incidence of early pelvic floor muscle abnormalities, postoperative pelvic floor muscle function and life would still be affected to a certain extent, and early instruction of pelvic floor rehabilitation training for pregnant women was beneficial to the recovery of pelvic floor function.

Acute Effect of a Half-Marathon over the Muscular Function and Electromyographic Activity of the Pelvic Floor in Female Runners with or without Urinary Incontinence: A Pilot Study.

to verify the acute effect of running a half marathon on pelvic floor muscle (PFM) function and electromyographic (EMG) activity in female runners with and without urinary incontinence. This is a cross-sectional pilot study. The sample was divided into two groups: runners with urinary incontinence (with UI) and runners without urinary incontinence (without UI). A semi-structured form and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF) were used for data collection. The EMG and PFM function were evaluated using the PERFECT method before and immediately after running a half marathon. A total of 14 runners were included (8 with UI; 6 without UI). Runners with and without UI did not show significant differences for EMG and PERFECT. The acute effects of the half marathon on runners without UI were reduced PFM function in terms of strength (p = 0.00), reduced endurance (p = 0.02), and reduced repetition (p = 0.03), and an increase in EMG measured by the median frequency (p = 0.02). Runners with UI showed reduced PFM function in terms of strength (p = 0.05) and repetition (p = 0.01). there was no difference in the acute effects of the half marathon on PFM function and EMG in women with and without UI.

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

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. Sample size calculated as 92 patients with endometriosis, aged between 18 and 45years, 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%. 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 2s. 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.

Pelvic floor muscle function after grade II tears-Surface electromyography test-retest and differences between nulliparous and primiparous.

Vaginal birth is a risk factor for weakening of the pelvic floor muscles (PFM) and development of pelvic floor dysfunction (PFD). Perineal tears may decrease PFM function. PFM tone can be assessed with surface EMG (sEMG), but reliability studies of sEMG in women with perineal tears are lacking. The aims of this study were to evaluate test-retest and intrarater reliability of sEMG and compare PFM activation between nulliparous and primiparous. A sEMG test-retest was performed in 21 women (12 nulliparous and 9 primiparous with grade II tears) to assess intra-rater reliability during rest and maximal voluntary contraction (MVC) of the PFM. Intraclass Correlation Coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) were tested. A comparison between nulliparous'and primiparous'PFM activation during rest and MVC was performed. sEMG demonstrated fair reliability in nulliparous (ICC: 0.239; SEM: 5.2; MDC: 14.5) and moderate reliability in primiparous (ICC: 0.409; SEM: 1.5; MDC: 4.2) during rest. For peak MVC very good intrarater reliability was found in nulliparous (ICC: 0.92; SEM: 8.0; MDC: 22.2) and in primiparous (ICC: 0.823; SEM: 8.0; MDC: 22.2). Statistically significant lower PFM activation was found in primiparous women with perineal tear grade II than in nulliparous at rest (mean difference 9.1 µV, 95% confidence interval[CI] 3.0-19.0, p = 0.001), and during MVCpeak (mean difference 50.0 µV, 95% CI 10.0-120.0 p = 0.021). sEMG is reliable when measuring PFM activation in primiparous women with perineal tears grade II. Women with perineal tears grade II have lower PFM activation both during rest and MVC.

Does multiple-component intensive pelvic floor muscle training decrease muscle fatigue and symptoms in women with urinary incontinence?

A multiple-component intensive pelvic floor muscle training (MCI-PFMT) protocol was developed as a neurophysiological-based rehabilitation model to improve neuroplasticity. This study aimed to investigate the effects of the MCI-PFMT protocol on muscle fatigue and symptoms in women with urinary incontinence. This randomized controlled trial included 49 female patients with mixed urinary incontinence. Participants were divided into the MCI-PFMT group and the control group. The MCI-PFMT group performed supervised intensive pelvic floor muscle training, while the control group received bladder training and standard pelvic floor muscle training as a home program. Both training sessions were conducted 5 days a week for a single week. Participants' symptoms were evaluated with questionnaires, bladder diary, and pad tests. Superficial electromyography, ultrasonography, and the PERFECT scale were used to evaluate pelvic floor and abdominal muscle functions. In the post-treatment evaluation, symptoms were decreased in both groups, with a significant decrease in the MCI-PFMT group (p < 0.05). While average and peak work values of pelvic floor muscles, transversus abdominus, and internal oblique muscles increased in both groups, maximum voluntary contraction values of these muscles decreased (p < 0.05). A 12.7% decrease was observed in the maximum voluntary contraction values of pelvic floor muscles in the control group, while a 9.6% decrease was observed in the MCI-PFMT group. The MCI-PFMT protocol can lead to pelvic floor and abdominal muscle fatigue. However, it may be effective at decreasing symptoms in women with urinary incontinence. Additional studies on this issue are needed.

Multifunctional Evaluation Technology for Diagnosing Malfunctions of Regional Pelvic Floor Muscles Based on Stretchable Electrode Array Probe.

The pelvic floor dysfunction (PFD) has become a serious public health problem. Accurate diagnosis of regional pelvic floor muscle (PFM) malfunctions is vitally important for the prevention and treatment of PFD. However, there is a lack of reliable diagnostic devices to evaluate and diagnose regional PFM abnormality. In this work, we developed a multifunctional evaluation technology (MET) based on a novel airbag-type stretchable electrode array probe (ASEA) for the diagnosis of malfunctions of regional PFM. The inflatable ASEA has specifically distributed 32 electrodes along the muscles, and is able to adapt to different human bodies for tight contact with the muscles. These allow synchronous collection of high-quality multi-channel surface electromyography (MC-sEMG) signals, and then are used to diagnose regional PFM malfunctions and evaluate inter-regional correlation. Clinical trial was conducted on 15 postpartum stress urinary incontinence (PSUI) patients and 15 matched asymptomatic women. Results showed that SUI patients responded slowly to the command and have symptoms of muscle strength degeneration. The results were consistent with the relevant clinical manifestations, and proved the reliability of MET for multifunctional PFM evaluation. Furthermore, the MET can diagnose malfunctions of regional PFM, which is inaccessible with existing technology. The results also showed that the dysfunction of PSUI patients is mainly located in iliococcygeus, pubococcygeus, and urethral sphincter regions, and there is a weak correlation between these specific regions and nearby regions. In conclusion, MET provides a point-of-care diagnostic method for abnormal function of regional PFM, which has a potential for the targeted point-to-point electrical stimulation treatment and PFD pathology research.

Effects of acupuncture and pelvic floor muscle training on bladder dysfunction after spinal cord injury: A meta-analysis.

We aimed to systematically review and quantify the association between acupuncture and pelvic floor muscle exercise and bladder dysfunction rehabilitation in individuals with spinal nerve injury. A meta-analysis was conducted using an evidence-based nursing analysis method based on clinical evidence. China National Knowledge Infrastructure, PubMed, VIP database, Wan Fang database, Cochrane Library, and other databases were searched by computer from January 1, 2000 to January 1, 2021. The literature was searched for clinical randomized controlled trials on acupuncture stimulation, pelvic floor muscle function training, and bladder function recovery training after spinal cord nerve injury. Two reviewers independently used The Cochrane Collaboration recommended randomized controlled trial risk of bias assessment tool to evaluate the quality of the literature. Then, the meta-analysis was performed using RevMan 5.3 software. A total of 20 studies were included, with a total sample size of 1468 cases, including 734 patients in the control group and 734 patients in the experimental group. The results of our meta-analysis showed that acupuncture treatment [OR = 3.98, 95% CI (2.77, 5.72), Z = 7.49, P < .001] and pelvic floor muscle treatment [OR = 7.63, 95% CI (4.47, 13.04), Z = 7.45, P < .001] was statistically significant. Acupuncture and pelvic floor muscle exercise are effective intervention and treatment methods, which have obvious effects on rehabilitation treatment of bladder dysfunction after spinal nerve injury.

Effect of 3D Animation Combined with Teach-Back Health Education on Pelvic Floor Muscle Training in LARS Patients: A Randomized Controlled Trial

Aim. The present study aimed to evaluate the effect of 3D animation combined with teach-back health education on the recovery of low anterior resection syndrome (LARS) patients. Background. LARS is the most common problem after anus-preserving surgery in rectal cancer. Pelvic floor muscle training can promote the recovery of recto-anal function. Methods. Ninety-nine patients with LARS were randomly divided into control group, experiment group I, and experiment group II. The control group was guided by one-to-one verbal pelvic floor muscle training. The experiment group I was given self-made 3D animation along with one-to-one pelvic floor muscle guidance. The 3D animation and teach-back methods were used for training and guidance in the experiment group II. The outcome measures were scores of low anterior resection syndrome scale items, as well as the completion of training content. Results. The degree of completion of training content in the experiment group II was higher than that of the control group and experiment group I. The total score of LARSS in the experiment group II was significantly lower than in the control group and experiment group I. In particular, scores of loose stool incontinence, defecation frequency level, tenesmus, and defecation urgency in experiment group II were better than those in the control group. Conclusion. 3D animation combined with teach-back health education improved the mastery of pelvic floor muscle training theory and practice in LARS patients, and effectively reduced the symptoms. Implications for Nursing Management. This intervention promoted the recovery of pelvic floor muscle function in LARS patients and can be regarded as an effective measure to improve quality of life and provide better clinical care for patients.

Supervised versus unsupervised pelvic floor muscle training in the treatment of women with urinary incontinence - a systematic review and meta-analysis.

This study synthesized the effects of supervised and unsupervised pelvic floor muscle training (PFMT) programs on outcomes relevant to women's urinary incontinence (UI). Five databases were searched from inception to December 2021, and the search was updated until June 28, 2022. Randomized and non-randomized control trials (RCTs and NRCTs) comparing supervised and unsupervised PFMT in women with UI and reported urinary symptoms, quality of life (QoL), pelvic floor muscles (PFM) function/ strength, the severity of UI, and patient satisfaction outcomes were included. Risk of bias assessment of eligible studies was performed by two authors through Cochrane risk of bias assessment tools. The meta-analysis was conducted using a random effects model with the mean difference or standardized mean difference. Six RCTs and one NRCT study were included. All RCTs were assessed as "high risk of bias", and the NRCT study was rated as "serious risk of bias" for almost all domains. The results showed that supervised PFMT is better than unsupervised for QoL and PFM function of women with UI. There was no difference between supervised and unsupervised PFMT for urinary symptoms and improvement of the severity of UI. Results of patient satisfaction were inconclusive due to the sparse literature. However, supervised and unsupervised PFMT with thorough education and regular reassessment showed better results than those for unsupervised PFMT without educating patients about correct PFM contractions. Supervised and unsupervised PFMT programs can both be effective in treating women's UI if training sessions and regular reassessments are provided.

Pelvic floor muscle function in women with and without breast cancer: A cross-sectional study

Introduction:The aim of this study was to quantify PF muscle function in women with and without breast cancer using pressure manometry, digital palpation and transperineal ultrasound. Methods:This cross-sectional study included women with and without breast cancer. The primary outcome was PF muscle strength measured as maximal squeeze pressure (cmH2O). Differences between groups were analysed using independent t-tests or chi-square tests. Results:The group with breast cancer was older (mean age: 54 years) than the group without breast cancer (mean age: 38 years, p<0.0001). Participants with breast cancer had significantly weaker PF muscles as measured by maximal squeeze pressure (breast cancer group: mean 18 cmH2O, 95% CI 15, 21; control group: mean 29 cmH2O, 95% CI 27, 32; p<0.0001) and digital examination (strength rated as weak: 30% in participants with breast cancer compared to 9% in control group, p=0.0167). Relaxation ability was poorer in participants with breast cancer than control group participants (p=0.0039). Conclusion:Our cohort of women with breast cancer demonstrated reduced PF muscle strength and poorer relaxation ability compared to those without breast cancer. This finding suggests that therapies such as PF muscle training or relaxation techniques may be therapeutic targets to improve PF muscle function.

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

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. 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. 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. 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. 5.

A novel radiofrequency modulation therapy versus routine physiotherapy modalities in treatment of myofascial pelvic pain syndrome: a pilot randomized trial.

The current study aimed to compare the effectiveness of novel radiofrequency modulation (RM) therapy with a tailored physiotherapy course for patients with chronic pelvic pain (CPP) of myofascial origin, also known as myofascial pelvic pain syndrome (MPPS). We enrolled 46 patients with myofascial CPP to compare the effectiveness of a 10-session routine physiotherapy course versus a 6-session RM with an integrated device (HIGGS) in alleviating MPPS morbidity and pelvic floor muscle (PFM) rehabilitation. The primary outcome was reduction in pelvic pain after the final session and in the follow-up period 3 months after the final intervention session. The 6-session therapy in the RM group and the manual, biofeedback, and transcutaneous electrical nerve stimulation therapies in the physiotherapy group were similarly effective in reducing pain and improving PFM endurance after the final intervention session in each group, whereas perineometer readings and PFM strength were associated with greater improvements in the physiotherapy group. The results of this study demonstrated comparable effectiveness of RM in the management of MPPS and improvement of PFM function compared to routine physiotherapy programs with fewer sessions of therapy.

Multimodal measurements of levator bowl volume in nulligravid asymptomatic women: endovaginal ultrasound versus MRI.

Measurements of levator bowl volume using advanced imaging, may be predictive of pelvic floor muscle function. The aim of this study was to compare the volume of the levator bowl using both magnetic resonance imaging (MRI) and endovaginal ultrasound (EVU) of healthy asymptomatic women. All participants underwent a comprehensive interview including completion of the Pelvic Floor Distress Inventory Questionnaire-20 questionnaire, pelvic examination with a pelvic organ prolapse quantification evaluation, MRI, and EVU. The pelvic floor was segmented using Slicer and the MRI segmentations were trimmed using two methods: soft-tissue landmarks and the field of view (FOV) of the ultrasound volume. The levator bowl volume of the 3D segmented shapes was measured using Blender's 3D printing toolkit. Normality was tested using the Shapiro-Wilks test and comparisons were made using self-paired t tests. The final analysis included 19 patients. Levator bowl volume measured via MRI was larger than that measured in EVU (46.1 ± 7.9 cm3 vs 27.4 ± 5.9 cm3, p<0.001). Reducing the FOV of the MRI to that of EVU caused the MRI volume to be much closer to the EVU volume (35.5 ± 3.3 cm3 vs 27.4 ± 5.9 cm3, p<0.001); however, it remained significantly larger. Levator bowl volume measured using MRI was larger than that measured using EVU no matter the method of delineation of the levator muscles. Although EVU is safe, cheap, and easy to perform, it captures a smaller volume of levator bowel than MRI.

Gestational diabetes mellitus and pelvic floor function 6 weeks postpartum in Chinese women.

With the significant increase in its incidence, gestational diabetes mellitus (GDM) has received growing attention for its effect on pelvic floor function. This study was aimed at investigating the association of GDM with pelvic floor function and diastasis recti abdominis (DRA) in postpartum women. This is a retrospective cohort study. At 6 weeks postpartum, 1,133 postpartum women with vaginal delivery underwent routine examinations including measurement of the pelvic floor muscle (PFM) strength and endurance, determination of the stress urinary incontinence (SUI) by questionnaire, quantification of pelvic organ prolapse (POP) and assessment of DRA. Statistical analysis was performed using binary logistic regression and multiple linear regression analysis. One hundred and seventy-six (176) of the 1,133 women were confirmed to be suffering from GDM, with a rate of 15.53% (176 out of 1,133). The age and pre-pregnancy body mass index of the GDM group were significantly higher than those without GDM (p < 0.05). The GDM group was more likely to have smaller gestational age and a higher chance of having to undergo a lateral episiotomy. No statistically significant differences are found in PFM endurance (B: -0.025, p = 0.462) or PFM strength (B: -0.001, p = 0.979) between women with and without GDM. And these two groups are not significantly different in terms of the prevalence of SUI (19.3% vs 20.4%), POP (35.8% vs 37.5%) and DRA (29.0% vs 25.8%; p > 0.05). Pelvic floor muscle function and SUI/POP/DRA prevalence of women at 6 weeks postpartum are not significantly affected by GDM.

Is there a difference in pelvic floor muscle tone between women with and without pelvic pain? A systematic review and meta-analysis.

Alterations in pelvic floor muscle (PFM) function have been observed in women with persistent noncancer pelvic pain (PNCPP) as compared with women without PNCPP; however, the literature presents conflicting findings regarding differences in PFM tone between women with and without PNCPP. To systematically review the literature comparing PFM tone in women with and without PNCPP. MEDLINE, Embase, Emcare, CINAHL, PsycINFO, and Scopus were searched from inception to June 2021 for relevant studies. Studies were included that reported PFM tone data in women aged ≥18years with and without PNCPP. The risk of bias was assessed with the National Heart, Lung, and Blood Institute Quality Assessment Tool. Standardized mean differences (SMDs) for PFM tone measures were calculated via random effects models. Resting PFM tone parameters, including myoelectrical activity, resistance, morphometry, stiffness, flexibility, relaxation, and intravaginal pressure, measured by any clinical examination method or tool. Twenty-one studies met the inclusion criteria. Seven PFM tone parameters were measured. Meta-analyses were conducted for myoelectrical activity, resistance, and anterior-posterior diameter of the levator hiatus. Myoelectrical activity and resistance were higher in women with PNCPP than in women without (SMD = 1.32 [95% CI, 0.36-2.29] and SMD = 2.05 [95% CI, 1.03-3.06], respectively). Women with PNCPP also had a smaller anterior-posterior diameter of the levator hiatus as compared with women without (SMD = -0.34 [95% CI, -0.51 to -0.16]). Meta-analyses were not performed for the remaining PFM tone parameters due to an insufficient number of studies; however, results of these studies suggested greater PFM stiffness and reduced PFM flexibility in women with PNCPP than in women without. Available evidence suggests that women with PNCPP have increased PFM tone, which could be targeted by treatments. A comprehensive search strategy was used with no restriction on language or date to review studies evaluating PFM tone parameters between women with and without PNCPP. However, meta-analyses were not undertaken for all parameters because few included studies measured the same PFM tone properties. There was variability in the methods used to assess PFM tone, all of which have some limitations. Women with PNCPP have higher PFM tone than women without PNCPP; therefore, future research is required to understand the strength of the relationship between pelvic pain and PFM tone and to investigate the effect of treatment modalities to reduce PFM tone on pelvic pain in this population.

Is it time for doctors to Rx vibrators? A systematic review of pelvic floor outcomes

Abstract Introduction Vibrators and similar devices are an underutilized treatment modality in pelvic and sexual medicine, likely because of the limited knowledge on the health benefits of their use. Objectives The aim of this study was to review available data regarding the effect of vibrator use on sexual function, pelvic floor function, and chronic unexplained vulvar pain. Methods We performed a systematic literature review of PubMed, Embase, and MEDLINE from inception to March 2021 per the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses). The search was based on the following keywords: sex toy woman, pelvic vibrator, sexual stimulation vibrator, vaginal vibrator, vibrator pelvic floor, vibrator incontinence, and vulvar pain vibrator. An overall 586 articles were identified. Studies that met inclusion criteria were reviewed: original research, sample of women, vibrator use, and application to the pelvic/genital area. Exclusion criteria included case reports, unrelated content, vibrator not applied to the pelvic/genital area, male participants, or conditions of interest not addressed. A total of 17 original studies met the criteria and were reviewed in depth. Results After review of the literature and identification of articles appropriate for the study, there were 8 studies surrounding sexual function, 8 on pelvic floor function (muscle strength/urinary incontinence), and 1 on vulvar pain. Among the identified studies, vibrators were considered an accepted modality to enhance a woman’s sexual experience, improve pelvic floor muscle function, and facilitate treatment of vulvar pain. Conclusions Vibrators are not well studied, and given the promising benefits demonstrated in the articles identified, future research efforts should be directed toward investigating their utility. Considering the potential pelvic health benefits of vibrators, their recommendation to women could be included in our pelvic floor disorder treatment armamentarium.

The Role of Physiotherapy in Parity-Induced Flatus Incontinence: A Case Report

Gas incontinence also known as Flatus incontinence is a common postpartum anal incontinence which impairs social participation and also lacks established protocol of management. Symptom persistency has been reported after perineal muscles repair due to weakness/ loss in function of the pelvic floor muscles. This case report describes about the importance and effectiveness of Pelvic Floor Muscle Rehabilitation (PMR) in a 28year old primiparous woman, four months postpartum who presented with parity-induced flatus incontinence aggravated after sexual activities at a the Physiotherapy clinic of a state government owned hospital located in the south eastern part of Nigeria. Pelvic Muscle Rehabilitation (PMR) and Stabilization exercises were administered thirty minutes (30mins) to forty-five minutes (45mins) three times (3x), a week (1 week) for four weeks (4weeks). There was a significant reduction in Mark’s (Vaizey) score by more than 2 points at the end of the four weeks of physiotherapy intervention and also patient recorded improvement in all the domains of faecal incontinence quality of life scale, pelvic floor muscle strength (anal squeeze pressure) and pelvic floor muscle function (endurance and coordination).

Risk Factors and Countermeasures of Stress Urinary Incontinence after Mesh Implantation for Patients with Pelvic Organ Prolapse.

We aimed to explore the risk factors and countermeasures of stress urinary incontinence (SUI) after mesh implantation for patients with pelvic organ prolapse (POP). A total of 224 POP patients undergoing mesh implantation from January 2018 to December 2021 were divided into group A (n = 68, postoperative new-onset SUI) and group B (n = 156, without postoperative new-onset SUI). Their clinical data were collected, and the treatment outcomes were analyzed. The independent risk factors for postoperative new-onset SUI were determined through multivariate logistic regression analysis. A risk-scoring model was established and assessed. The patients with postoperative new-onset SUI were divided into low-, moderate- and high-risk groups using this model. Mesh implantation significantly improved the pelvic floor muscle strength and function of patients. Multivariate logistic regression analysis revealed that age ≥50 years old, gravidity ≥3 times, parity ≥3 times, history of macrosomia delivery, history of chronic respiratory diseases, vaginal delivery, and perineal laceration were independent risk factors for postoperative new-onset SUI, and pelvic floor muscle training by biofeedback electrical stimulation was a protective factor (p < 0.05). The risk-scoring model was safe, reliable and practical, with high discrimination, accuracy and efficiency. Age ≥50 years old, gravidity ≥3 times, parity ≥3 times, history of macrosomia delivery, history of chronic respiratory diseases, vaginal delivery, and perineal laceration are independent risk factors for postoperative new-onset SUI, and pelvic floor muscle training by biofeedback electrical stimulation is a protective factor. Therefore, POP patients with new-onset SUI following mesh implantation should receive more pelvic floor muscle training.

Portable Dynamometer-Based Measurement of Pelvic Floor Muscle Force

In attempts to improve the quality of life of women, continuous projects are sought between rehabilitation intervention and engineering. Using the knowledge of the pelvic floor muscle (PFM) physiology, assessment and training methods are developed to reduce lower urinary tract symptoms such as urinary incontinence. Therefore, this paper covers the design and implementation of a portable vaginal dynamometer. A PFM probe is designed, 3D printed, assembled, and tested in ten women to assess its acceptability and usability. The feedback from the usability study is used to optimize the PFM probe design. A vaginal dynamometer is developed based on the designed PFM probe, then tested for linearity, repeatability, hysteresis, noise and heat effect, and power consumption. The variability between the different produced PFM probe prototypes is evaluated. Force measurements are made using a load cell. Wireless communication is performed through a Bluetooth low energy transceiver v5.0, with a corresponding interface on both computer and smartphone. The device operates at a 3.3V supply and achieves a power consumption of 49.5 mW in operating mode. Two PFM probe sizes are designed to accommodate different vaginal hiatus sizes, based on usability study feedback. The proposed system allows the physiotherapist to wirelessly monitor variation in pelvic floor muscle force during assessment and/or training. The testing results showed that the newly designed system has the potential to measure the PFM function in functional conditions such as the standing position.
