Abstract
BACKGROUND The minimal important difference is a valuable metric in ascertaining the clinical relevance of a treatment, offering valuable guidance in patient management. There is a lack of available evidence concerning this metric in the context of outcomes related to female urinary incontinence, which might negatively impact clinical decision-making. OBJECTIVES To summarize the minimal important difference of patient-reported outcome measures associated with urinary incontinence, calculated according to both distribution- and anchor-based methods. METHODS This is a systematic review conducted according to the PRISMA guidelines. The search strategy including the main terms for urinary incontinence and minimal important difference were used in five different databases (Medline, Embase, CINAHL, Web of Science, and Scopus) in 09 June 2021 and were updated in January 09, 2024 with no limits for date, language or publication status. Studies that provided minimal important difference (distribution- or anchor-based methods) for patient-reported outcome measures related to female urinary incontinence outcomes were included. The study selection and data extraction were performed independently by two different researchers. Only studies that reported the minimal important difference according to anchor-based methods were assessed by credibility and certainty of the evidence. When possible, absolute minimal important differences were calculated for each study separately according to the mean change of the group of participants that slightly improved. RESULTS Twelve studies were included. Thirteen questionnaires with their respective minimal important differences reported according to distribution (effect size, standard error of measurement, standardized response mean) and anchor-based methods were found. Most of the measures for anchor methods did not consider the smallest difference identified by the participants to calculate the minimal important difference. All reports related to anchor-based methods presented low credibility and very low certainty of the evidence. We pooled 20 different estimates of minimal important differences using data from primary studies, considering different anchors and questionnaires. CONCLUSIONS There is a high variability around the minimal important difference related to patient-reported outcome measures for urinary incontinence outcomes according to the method of analysis, questionnaires, and anchors used, however, the credibility and certainty of the evidence to support these is still limited.

Abstract
Background: Exercise can stress the pelvic floor muscles (PFMs). This study sought to assess the strength of the PFMs according to the level of physical exercise. Methods: An analytical observational study was carried out using digital palpation and dynamometry measurements to assess PF strength. Healthy nulliparous women were stratified according to physical exercise (physically active and sedentary) and level of physical exercise (elite, amateur, and sedentary). Results: Fifty-four women were analyzed, with a mean age of 25.64 (5.33) years and a BMI of 21.41 (2.96) kg/m2. Differences in the passive force and strength were observed between both groups of women (p < 0.05), and the strength was around two times higher in physically active women (p < 0.05). The strength was similar between elite female athletes and sedentary women (p > 0.05), but statistical differences were found with amateurs (p < 0.05). The PFM strength (p = 0.019) of elite female athletes (0.34 N) was almost half that of amateurs (0.63 N) and twice as strong as that of sedentary women (0.20 N). However, these differences were not significant using digital palpation (p = 0.398). Conclusions: Women who exercise generally have greater PFM strength than women who do not exercise. Physical exercise could strengthen the PFM; however, the high intensity demanded by high-level sports does not seem to proportionally increase the strength of the PFMs.

Abstract
BACKGROUND Vaginal manometry is regarded as an objective method to assess pelvic floor muscles (PFM) function and can measure several variables during contraction. OBJECTIVE To determine which variables could differentiate women with/without a weak/strong PFM contraction and determine their cut-off points. METHODS This is a diagnostic accuracy study performed on 156 women with a mean age of 40.4 (SD, 15.9) years. The reference test was vaginal palpation and the index test was vaginal manometry (Peritron™ manometer). Variables were pressure at rest, pressure achieved with maximal voluntary contraction (MVC), MVC average, duration, gradient, and area under the curve (AUCm). The Receiver Operating Curve (AUC/ROC) and logistic regression were used to analyze the data and obtain cut-off points. RESULTS Excellent ability to discriminate women with a weak/strong PFM contraction was found for MVC average (cut-off: 28.93 cmH2O), MVC (cut-off: 38.61 cmH2O), and the AUCm (cut-off: 1011.93 cm²*s). The gradient variable had good discrimination ability (AUC/ROC=0.81; cut-off: 28.68 cmH2O/s). The MVC average assessed by manometry, menopausal status, and the presence of stress urinary incontinence (SUI) were associated with a weak/strong PFM contraction in the multivariate analysis; however, the most parsimonious model to discriminate weak/strong PFM contraction included only the MVC average (AUC/ROC = 0.95; sensitivity: 0.87; specificity: 0.91). CONCLUSION These results suggest which manometry variables are appropriate to assess and classify PFM function in females. These could be used to help physical therapists to make clinic decisions about the management of female PFM.

Abstract
OBJECTIVE The prevalence of stress urinary incontinence (SUI) increases around menopause. The quality of life of perimenopausal and postmenopausal women with SUI is significantly affected. This study aimed to investigate the prevalence of SUI and the associated risk factors in a population of Chinese perimenopausal and postmenopausal women. METHODS A total of 273 perimenopausal and postmenopausal women were enrolled, and a cross-sectional study was conducted. SUI was defined as an involuntary loss of urine with increases in abdominal pressure. Data including personal characteristics, menopause information, estrogen levels, and pelvic floor muscle strength levels were statistically analyzed. RESULTS The study enrolled 158 (57.9%) perimenopausal and 115 (42.1%) postmenopausal women. Sixty-six (41.8%) perimenopausal women and 56 (48.7%) postmenopausal women complained of SUI. The mean age was 49.42 ± 5.58 years. Body mass index over 24 kg/m2 (odds ratio [OR] 2.02, 95% confidence interval [CI] 1.07-3.81), vaginal delivery (OR 2.47, 95% CI 1.33-4.58), and diabetes (OR 4.65, 95% CI 1.23-17.62) were high-risk factors for SUI. Climacteric symptoms (evaluated by Kupperman index scores) were statistically related to SUI, and among the 13 symptoms, insomnia, nervousness, weakness and fatigue, arthralgia and myalgia, headache, palpitation, and sexual complaints were all correlated with SUI in perimenopausal and postmenopausal women. CONCLUSIONS Several factors are associated with SUI in Chinese perimenopausal and postmenopausal women. Obesity, vaginal delivery, climacteric symptoms, and diabetes were identified as the most notable risk factors. The management strategy could focus on the prevention and management of risk factors.

Abstract
IMPORTANCE Methods for pelvic floor muscle (PFM) strength testing are limited by their subjective nature, prohibitive cost, training burden, or lack of validation. OBJECTIVES The objectives of this study are to validate a new, inexpensive, and accessible method for PFM strength testing using a 30-mL Foley balloon inserted into the vagina, the Foley Balloon Pull Test (FPT), and to demonstrate external validity by comparing the subjective Oxford Muscle Grading Scale (OMGS) scores to measurements obtained with the FPT. Secondary objectives include demonstrating repeatability and internal validity of the FPT. STUDY DESIGN Participants underwent PFM strength testing with the OMGS on a 0 to 5 scale. A gauge was attached to the Foley balloon to measure the force required to remove the balloon from the vagina. Three measures at rest and 3 measures during maximal muscle contraction were recorded. Cross-sectional data were analyzed. RESULTS One hundred one participants were included; there were no adverse events. The ratio of contraction FPT measurements to at-rest measurements revealed moderate linear and rank order correlation with the OMGS ( R2 = 0.54, P < 0.001, and R2 = 0.58, P < 0.001). The reliability of repeated measurements was highly correlated, with intraclass correlation coefficients >0.95. An FPT ratio of 1.75 discriminated between weak (0-2) and strong (3-5) OMGS scores with an area under the curve of 0.86. CONCLUSION The FPT is an internally reliable, simple, and externally valid method of PFM strength testing.

Abstract
INTRODUCTION Functional intestinal constipation (FIC) has a high prevalence worldwide. It is higher in adult and elderly women, and in those with alterations in the pelvic floor muscle (PFM) structure and function. OBJECTIVE The primary aim of this study was to characterize PFM function, including tone, of women with and without FIC. The secondary aim was to assess and compare the general and symptom-related quality of life (QoL) between participants with and without FIC and its correlation with the assessed PFM function. METHODS This was a cross-sectional observational study, the outcomes were assessed using vaginal palpation, vaginal manometry and validated questionnaires: the Pelvic Floor Impact Questionnaire Short Form 7 (PFIQ-7), the Pelvic Floor Distress inventory (PFDI-20), and the Short-Form Health Survey (SF-36). This study included 60 women, 30 with FIC and 30 without FIC. The mean age of women with FIC was 48.2 years (standard deviation [SD] 12.22) and 51 years (SD 13.47) for those without FIC. Both groups were overweight. There was a significant difference between groups in the bowel domain of the PFIQ-7 (p = 0.016) and in the anal dysfunction domain of the PFDI-20 (p < 0.001), being higher in those women with FIC. Women with FIC presented a significantly worse ability to voluntarily relax their PFM (38.3%) than those without FIC (11.7%; p = 0.008). participants without FIC presented higher values of maximum voluntary contraction (MVC) assessed by vaginal manometry compared to participants without FIC (p = 0.008). PFM tone was not different between groups. CONCLUSION Women with FIC have more difficulty in relaxing their PFM and lower MVC values than women without FIC. FIC negatively impacts women's symptom-related QoL. The main contribution of this study was to reavel the difficulty of the participants with FIC to relax their PFM. This finding is important to guide clinical decision making for an adequate treatment program direct to women with FIC.

Abstract
OBJECTIVE The purpose of this study was to evaluate whether the clinical assessment of pelvic floor muscles and the diastasis recti abdominis could predict the severity of pelvic girdle pain during the first year postpartum. METHODS Between 2018 and 2020, 504 women were recruited to this prospective longitudinal cohort study. At 2 to 3 months postpartum, their pelvic floor muscles and diastasis recti abdominis were assessed using vaginal palpation, observation, and caliper measurement. The participants completed the Pelvic Girdle Questionnaire (PGQ) at 2 to 3, 6, 9, and 12 months postpartum. Mixed-effect models were used to determine how the results of pelvic floor muscle and diastasis recti abdominis assessments predicted the PGQ score. A sub-analysis for middle to high PGQ scores was conducted. RESULTS Maximal voluntary pelvic floor muscle contractions ≥3 (Modified Oxford Scale, scored from 0 to 5) predicted a decreased PGQ score (β = -3.13 [95% CI = -5.77 to -0.48]) at 2 to 3 months postpartum, with a higher prediction of a middle to high PGQ score (β = -6.39). Diastasis recti abdominis width did not have any significant correlation with the PGQ score. A sub-analysis showed that a diastasis recti abdominis width ≥35 mm predicted an increased PGQ score (β = 5.38 [95% CI = 1.21 to 9.55]) in women with pelvic girdle pain. CONCLUSION The distinction between weak and strong maximal voluntary pelvic floor muscle contractions is an important clinical assessment in women with postpartum pelvic girdle pain. The exact diastasis recti abdominis width, measured in millimeters, showed no clinical relevance. However, a diastasis recti abdominis width ≥35 mm was associated with a higher PGQ score, and further research about this cutoff point in relation to pain is needed. IMPACT This study highlights the importance of clinical assessment of pelvic floor muscles in patients with postpartum pelvic girdle pain. A better understanding of the role of this muscle group will enable more effective physical therapist treatment of pelvic girdle pain.

Abstract
OBJECTIVE 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. METHODS 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. RESULTS 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. DISCUSSION/CONCLUSION 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.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to synthesize the scientific evidence on the relationship of exercise with morphology and muscle function parameters of the female pelvic floor. The design was a systematic review. METHODS Searches were performed in MEDLINE, PubMed, CINAHL, Web of Science, SCOPUS, SportDiscuss, and Google Scholar up to April 2021. Observational and experimental studies evaluating the morphology and/or function of the pelvic floor muscles (PFMs) in women were eligible. Studies reporting exercise or sports disciplines as exposure/intervention were included. RESULTS Twenty-five studies were included. Compared with the control group, women performing vigorous and high-impact exercises exhibited lower maximum voluntary contraction of the PFM and those performing moderate exercise had better maximum voluntary contraction. Exercise practitioners had a larger hiatal area at rest, during contraction, and during Valsalva, and greater bladder neck descent than the control group. CONCLUSIONS The results of this review demonstrate an inverse relationship of PFM maximum voluntary contraction with exercise intensity. Qualitative synthesis showed that the studies found favorable outcomes for the control group in terms of hiatal area during contraction and Valsalva and bladder neck displacement.

Abstract
The aim of the study was to determine effects of adding transperineal ultrasound (TPUS) biofeedback to individualized pelvic floor muscle training (PFMT) on extensibility of the pelvic floor muscle and anterior pelvic organ prolapse (POP) in postmenopausal women. A total of 77 patients with POP at stage I or stage II were admitted to Beijing Shijitan Hospital, China, from January 2017 to October 2018. They were randomly divided into a control group (CG) (n = 37) or a study group (SG) (n = 40). Both SG and CG received a 12-week PFMT including health education, verbal instruction, and home training. However, the SG, but not the CG, received additional TPUS biofeedback. Data of these patients were retrospectively reviewed. The distance from the lowest point of the bladder to the inferior-posterior margin of the symphysis pubis (BSP) and the levator hiatus area (LHA) were measured on maximal Valsalva via TPUS before and after the 12-week PFMT. Correct pelvic floor muscle contraction (PFMC) rates before and after PFMT were compared between the two groups. The correct PFMC rate was higher in the SG than that in the CG (92.5% vs. 73%; x2 = 5.223, p=0.022). The BSP was increased but the LHA was reduced after the 12-week PFMT in both groups compared to those before PFMT (all p < 0.05). However, after the PFMT, the SG showed greater improvement than the CG for both BSP (0.77 ± 0.71 cm vs. 0.11 ± 0.66 cm, p < 0.05) and LHA (20.69 ± 2.77 cm2 vs. 22.85 ± 3.98 cm2, p < 0.05). TPUS might be an effective biofeedback tool for PFMT in clinical practice. Individualized PFMT with TPUS biofeedback could significantly attenuate POP severity and strengthen the extensibility of pelvic floor muscle in postmenopausal women when they are under increased intraabdominal pressure.

Abstract
OBJECTIVE The purpose of this study was to assess the immediate effect of verbal and visual feedback on pelvic floor muscles (PFM) in nulliparous women without pelvic floor dysfunction. METHODS In this observational, single-assessor, cross-sectional study, 45 female university students were evaluated using bidigital vaginal palpation and vaginal surface electromyography (EMG). EMG assessments were performed at 2 time points (T1 and T2). According to the protocol, participants performed 5 maximal voluntary contractions (MVC) with 10-second intervals, 5 sustained voluntary contractions (SVC) for 10 seconds, and a 60-second voluntary contraction until fatigue (CUF) before (T1) and after (T2) receiving verbal instructions and visual feedback on PFM contractions. At T2, women received visual feedback on their PFM contraction. Root mean square (RMS) for each repetition (MVC and VCF) was recorded, and mean value was calculated. Compensatory mechanisms during contraction were recorded visually. The difference in mean RMS (mV) for MVC, SVC, and CUF; curve integral for MVC, SVC, and CUF; median frequency (Hz) for CUF between T1 and T2 were analyzed with repeated measures multivariate analysis of variance. RESULTS Before the instructions, most participants (95.6%) performed PFM MVC using at least 1 compensatory mechanism. PFM EMG outcomes changed at T2: RMS and curve integral were reduced in T2 (P < .05) for MVC, SVC, and CUF. The median frequency increased from T1 to T2 in the CUF group (P = .01). CONCLUSION Verbal and visual feedback had an immediate impact on the EMG activity of PFM in nulliparous continent women.

Abstract
INTRODUCTION AND HYPOTHESIS The International Continence Society recommends vaginal palpation as a method for assessing pelvic floor muscle (PFM) function. Our aim was to analyze the agreement between preferences of examiner and participants according to unidigital and bidigital vaginal palpation during PFM assessment. The second aim was to investigate qualitatively women's perception of vaginal palpation. METHODS Maximal voluntary contractions (MVCs) were requested during both types of vaginal palpation and were classified by the Modified Oxford Scale (MOS). Examiner and participants answered if they had preferences regarding vaginal palpation. Women answered qualitatively what they felt during the assessment. Cohen's linear kappa (κ) evaluated the agreement after allocation of the women with a weaker and stronger MVC and qualitative analysis was performed by transcription considering age range (18-35; 36-59; ≥60 years). RESULTS Agreement was almost zero for women with weaker and stronger MVC at unidigital (κ = 0.06 and κ = -0.12) and bidigital vaginal palpation (κ = 0.008 and κ = 0.005). Participants associated bidigital palpation with more perception and an easier way of contracting the PFMs. Women between 36 and 59 years associated unidigital palpation with a harder but comfortable way of contracting the PFMs. Subjects aged ≥60 years associated bidigital palpation with an uncomfortable, harder way of contracting PFM, with less space into the vagina. CONCLUSIONS Agreement between preferences was almost zero neither between women with a weaker and stronger PFM contraction, nor between the types of vaginal palpation. Bidigital palpation increased women's perception, made the contraction easier, and was associated with less space in the vaginal canal and less comfort.

Abstract
INTRODUCTION The terminology for female and male pelvic floor muscle (PFM) assessment has expanded considerably since the first PFM function and dysfunction standardization of terminology document in 2005. New terms have entered assessment reports, and new investigations to measure PFM function and dysfunction have been developed. An update of this terminology was required to comprehensively document the terms and their definitions, and to describe the assessment method and interpretation of the finding, to standardize assessment procedures and aid diagnostic decision making. METHODS This report combines the input of members of the Standardisation Committee of the International Continence Society (ICS) Working Group 16, with contributions from recognized experts in the field and external referees. A logical, sequential, clinically directed assessment framework was created against which the assessment process was mapped. Within categories and subclassifications, each term was assigned a numeric coding. A transparent process of 12 rounds of full working group and external review was undertaken to exhaustively examine each definition, plus additional extensive internal development, with decision making by collective opinion (consensus). RESULTS A Terminology Report for the symptoms, signs, investigations, and diagnoses associated with PFM function and dysfunction, encompassing 185 separate definitions/descriptors, has been developed. It is clinically based with the most common assessment processes defined. Clarity and user-friendliness have been key aims to make it interpretable by clinicians and researchers of different disciplines. CONCLUSION A consensus-based Terminology Report for assessment of PFM function and dysfunction has been produced to aid clinical practice and be a stimulus for research.

Abstract
Pelvic floor dysfunction is prevalent, with multifactorial causes and variable clinical presentations. Accurate diagnosis and assessment of the involved structures commonly requires a multidisciplinary approach. Imaging is often complementary to clinical assessment, and the most commonly used modalities for pelvic floor imaging include fluoroscopic defecography, magnetic resonance defecography, and pelvic floor ultrasound. This collaboration opinion paper was developed by representatives from multiple specialties involved in care of patients with pelvic floor dysfunction (radiologists, urogynecologists, urologists, and colorectal surgeons). Here, we discuss the utility of imaging techniques in various clinical scenarios, highlighting the perspectives of referring physicians. The final draft was endorsed by the Society of Abdominal Radiology (SAR), American Urogynecologic Society (AUGS), and the American Urological Association (AUA).

Abstract
INTRODUCTION The pelvic floor muscle (PFM) could affect female sexual functions. The hip muscles are morphologically and functionally linked to PFM and are important elements of female sexual attraction. AIM To determine the relationship between female sexual function and hip muscle strength and PFM functions in women with stress urinary incontinence (SUI). METHODS A total of 42 women with SUI were recruited in this study. Female sexual function was measured using the pelvic organ prolapse urinary incontinence sexual function questionnaire (PISQ). PFM functions were measured using a perineometer. Hip muscle strength was measured using a Smart KEMA tension sensor. The relationship between female sexual function and PFM function and hip muscle strength was assessed using Pearson correlation coefficients and multiple regression analyses with forward selection. MAIN OUTCOME MEASURES PISQ score, PFM functions (strength and endurance), and strength of hip extensor, abductor, and adductor were the main outcome measures. RESULTS For the behavioral/emotive domain in the PISQ, hip extensor strength (r = 0.452), PFM strength (r = 0.441), PFM endurance (r = 0.362), and hip adductor strength (r = 0.324) were significantly correlated and hip extensor strength emerged in multiple regression. For the physical domain in the PISQ, hip abductor strength (r = 0.417), PFM endurance (r = 0.356), hip adductor strength (r = 0.332), and PFM strength (r = 0.322) were significantly correlated and hip abductor strength entered in multiple regression. For partner-related domain in the PISQ, hip adductor (r = 0.386) and abductor strength (r = 0.314) were significantly correlated and hip adductor strength appeared in multiple regression. For the PISQ total score, hip extensor strength (r = 0.484), PFM endurance (r = 0.470), hip adductor strength (r = 0.424), hip abductor strength (r = 0.393), and PFM strength (r = 0.387) were significantly correlated and hip extensor strength and PFM endurance emerged in multiple regression. CONCLUSION The female sexual function could be related to not only PFM functions but also hip muscle strength in women with SUI. Hwang UJ, Lee MS, Jung SH, Ahn SH, Kwon OY.

Abstract
AIMS To investigate the intrarater reliability of visual inspection and digital palpation to classify women's ability to perform a voluntary pelvic floor muscle (PFM) contraction and the association between the two methods. METHODS This was a test-retest clinical study including 44 women. The ability to perform a PFM voluntary contraction was evaluated two times in all participants using visual inspection and digital palpation. All analyzed participants were assessed with a 7-day interval between the two assessments and by the same examiner. Kappa's agreement coefficient was used to estimate the intrarater reliability, and Fisher's exact test was used to analyze association between the two methods. RESULTS This study found a substantial intrarater reliability of visual inspection (k = 0.73; p < .001) and digital palpation (k = 0.74; p < .001). A significant association between visual inspection and digital palpation was found at both time points (p < .001). CONCLUSION Both visual inspection and digital palpation have substantial intrarater reliability and visual inspection can be recommended when vaginal palpation is not tolerated.

Abstract
PURPOSE The aim of this study was to describe verbal instructions used to obtain a voluntary pelvic floor muscle contraction and to evaluate their understanding and acceptability. METHODS This prospective study led in two phases. A questionnaire was submitted to experts to collect the most frequently used instructions to obtain a PFMC. Then a questionnaire was submitted to subjects in order to: estimate the pelvic floor anatomical knowledge; estimate understanding and acceptability of these instructions; select the best instruction. RESULTS First phase: 46 experts proposed 356 instructions. Forty-four percent were functional instructions ("hold a gas"), 40% anatomical ("squeeze your anus") and 16% allied both. Fifteen instructions for the women and 11 for the men were selected. Second phase: 33 subjects completed the questionnaire. More than 75% had correct answers for anatomical knowledge. The instructions judged by the subjects as the most adapted to obtain a PFMC were: "contract the anus", "do as if you wanted to hold a strong desire to void". The items including "perineum" or "vagina" were less understood. CONCLUSIONS The more understandable and acceptable instruction to assess the PFMC is the association of two simple instructions: one anatomical and one functional. LEVEL OF EVIDENCE 4.

Abstract
INTRODUCTION AND HYPOTHESIS The aim of the present study was to evaluate the inter- and intra-rater reliability of the PERFECT scheme assessed by uni- and bidigital vaginal palpation in young nulligravid women. METHODS Forty healthy women [median age 22 (19-34) years] were evaluated by unidigital vaginal palpation by both Examiners A and C, while the other 40 participants [median age 23.5 (19-35) years] were assessed by Examiners B and C by bidigital vaginal palpation. Inter- and intra-rater reliability of all items of the PERFECT scheme were evaluated: P = power (Modified Oxford Scale); E = endurance; R = repetitions; F = fast contractions. Cohen's linear weighted kappa (κw) was used to assess the reliability of the power, while the intraclass correlation coefficient (ICC) was applied for the other items. A priori sample size calculation found that 40 participants would be adequate. RESULTS Inter-rater reliability of unidigital palpation was considered fair for power (κw = 0.34) and poor for other items (ICC < 0.50); bidigital inter-rater reliability was considered moderate (power: κw = 0.57; endurance: ICC = 0.53; fast contractions: ICC = 0.65, respectively) and low (repetitions: ICC = 0.27). Intra-rater reliability was substantial for power (κw = 0.73 and 0.62), moderate for fast contractions (ICC = 0.63 and 0.51) and poor for repetitions (ICC < 0.50), respectively, for uni- and bidigital palpation. Endurance showed poor (ICC < 0.50) and moderate (ICC = 0.61) reliability for uni- and bidigital palpation. CONCLUSIONS The PERFECT scheme carried out by bidigital vaginal palpation presents higher reliability when two examiners carry out the physical examination. When one examiner is responsible for PFM assessment, both types of palpation are recommended for evaluation of power and fast contraction; endurance should be evaluated using bidigital palpation. Examiners should be careful during the assessment of repetition of sustained contractions because inter- and intra-reliabilities for both types of palpation were classified as poor.

Abstract
AIMS To evaluate inter- and intrarater reliability of unidigital and bidigital vaginal palpation of pelvic floor muscle (PFM) maximal voluntary contraction (MVC) according to PFM risk factors and dysfunctions. METHODS A total of 187 women were recruited and evaluated by two examiners. Both performed the evaluation of MVC with unidigital and bidigital palpation, graded by Modified Oxford Scale. After 7-10 days, one examiner repeated the assessment. To analyze reliability by Cohen's linear Kappa (κw), participants were allocated into different groups according to: body mass index (BMI), menopause, parity, type of delivery and PFM dysfunctions, as pelvic organ prolapse (POP), constipation, urgency, urgency urinary incontinence, pelvic pain, and stress urinary incontinence. RESULTS Inter-rater reliability of unidigital palpation was considered fair (κw = 0.21-0.40) to moderate (κw = 0.41-0.60) according to BMI, postmenopausal status, parity, type of delivery, and PFM dysfunctions. Inter-rater reliability of bidigital palpation varied from none (κw = 0.00-0.20) to moderate for all risk factors and PFM dysfunctions. Intra-rater reliability of unidigital palpation was considered fair only for women with POP (κw = 0.37) and moderate to substantial (κw = 0.61-0.80) to all other variables. Intra-rater reliability of bidigital palpation ranged from moderate to almost perfect (κw = 0.81-1.00). CONCLUSIONS When performing vaginal palpation, physiotherapists must consider the way that is performing the evaluation, as some PFM risk factors and dysfunctions could influence the inter- and intrarater reliability of unidigital and bidigital palpation.

Abstract
This paper covers the design and implementation of a proof of concept for a wireless system measuring pelvic floor muscle forces based on a dynamometer. The proposed device is the main component of a novel assessment tool intended for pelvic floor muscle rehabilitation in women suffering from urinary incontinence. The proposed system allows the physiotherapist to wirelessly monitor variation in pelvic floor muscle forces during assessment or training. Wireless communication is provided by a Bluetooth low energy transceiver and a corresponding interface designed for this purpose. Force measurements are sensed with strain gauge precision sensors operated in a Wheatstone bridge configuration. The designed module consumes 14 mW of power in operating mode. System design and experimental results are reported and discussed.

Abstract
OBJECTIVE Transabdominal ultrasound (TAU) is an easy and noninvasive way to evaluate and retrain pelvic floor muscle (PFM) function. The purpose of this study was to compare PFM activity in women with and without urinary incontinence (UI) by measuring bladder base displacement (as a marker for PFM activity) using TAU during PFM contraction, Valsalva's maneuver, and abdominal curl. METHODS Sixty-three women, aged 20-55 years, volunteered to participate in this cross-sectional study: 21 were continent and 42 had UI (21 stress urinary incontinence [SUI] and 21 mixed urinary incontinence [MUI]). Mean bladder base displacement in millimeters was measured to evaluate differences between the three groups (continent, SUI, and MUI) and also between the continent and UI groups during the performance of each maneuver. RESULTS No significant differences were seen between the three groups in bladder base elevation during PFM contraction (P > 0.05). Descent of the bladder base during Valsalva's maneuver and abdominal curl was significantly greater in women with SUI and MUI than in women in the continent group (P < 0.05). Comparison of the continent and UI groups showed no significant differences in elevation of the bladder base during PFM contraction, while descent of the bladder base was significantly greater in women with UI than in women in the continent group during Valsalva's maneuver and abdominal curl (P < 0.05). CONCLUSION TAU indicated that bladder base descent was greater in women with SUI and MUI than those in the continent group during the performance of maneuvers that increased intra-abdominal pressure. This effect may be due to decreased PFM performance in women with urinary incontinence.

Abstract
OBJECTIVES To evaluate the effect of preoperative pelvic floor muscle training (PFMT) on pelvic floor muscle (PFM) contraction, symptoms of pelvic organ prolapse (POP) and anatomical POP, 6 months after prolapse surgery, and to assess the overall changes in PFM contraction, POP symptoms and pelvic organ descent after surgery. METHODS This was a randomized controlled trial of 159 women with symptomatic POP, Stage 2 or higher, scheduled for surgery. Participants were randomized to intervention including daily PFMT from inclusion to surgery (n = 81) or no intervention (controls; n = 78). Participants were examined at inclusion, on the day of surgery and 6 months after surgery. PFM contraction was assessed by: vaginal palpation using the Modified Oxford scale (MOS; 0-5); transperineal ultrasound, measuring the percentage change in levator hiatal anteroposterior diameter (APD) from rest to maximum PFM contraction; vaginal manometry; and surface electromyography (EMG). POP distance from the hymen in the compartment with the most dominant prolapse and organ descent in the anterior, central and posterior compartments were measured on maximum Valsalva maneuver. POP symptoms were assessed based on the sensation of vaginal bulge, which was graded using a visual analog scale (VAS; 0-100 mm). Linear mixed models were used to assess the effect of PFMT on outcome variables. RESULTS Of the 159 women randomized, 151 completed the study, comprising 75 in the intervention and 76 in the control group. Mean waiting time for surgery was 22 ± 9.7 weeks and follow-up was performed on average 28 ± 7.8 weeks after surgery. Postoperatively, no difference was found between the intervention and control groups with respect to PFM contraction assessed by vaginal palpation (MOS, 2.4 vs 2.2; P = 0.101), manometry (19.4 vs 19.7 cmH2 O; P = 0.793), surface EMG (33.5 vs 33.1 mV; P = 0.815) and ultrasound (change in hiatal APD, 20.9% vs 19.3%; P = 0.211). Furthermore, no difference between groups was found for sensation of vaginal bulge (VAS, 7.4 vs 6.0 mm; P = 0.598), POP distance from the hymen in the dominant prolapse compartment (-1.8 vs -2.0 cm; P = 0.556) and sonographic descent of the bladder (0.5 vs 0.8 cm; P = 0.058), cervix (-1.3 vs -1.1 cm; P = 0.569) and rectal ampulla (0.3 vs 0.4 cm; P = 0.434). In all patients, compared with findings at initial examination, muscle contraction improved after surgery, as assessed by palpation (MOS, 2.1 vs 2.3; P = 0.007) and ultrasound (change in hiatal APD, 17.5% vs 20.1%; P = 0.001), and sensation of vaginal bulge was reduced (VAS, 57.6 vs 6.7 mm; P < 0.001). In addition, compared with the baseline examination, POP distance from the hymen in the dominant prolapse compartment (1.9 vs -1.9 cm; P < 0.001) and sonographic descent of the bladder (1.3 vs 0.6 cm; P < 0.001), cervix (0.0 vs -1.2 cm; P < 0.001) and rectal ampulla (0.9 vs 0.4 cm; P = 0.001) were reduced. CONCLUSIONS We found no effect of preoperative PFMT on PFM contraction, POP symptoms or anatomical prolapse after surgery. In all patients, PFM contraction and POP symptoms were improved at the 6-month follow-up, most likely due to the anatomical correction of POP. Copyright © 2020 ISUOG.

Abstract
AIM This study aims to determine the effectiveness of home-based pelvic floor muscle training (PFMT) on decreasing the severity of symptoms and improving the quality of life (QOL) among Omani women with stress urinary incontinence (SUI). METHODS A randomized controlled single-blind trial was conducted in three primary health care centers in Muscat. Eligible women who were diagnosed with SUI (from a concurrent phase-I study which was a cross-sectional study to determine the prevalence of urinary incontinence in Oman) were invited to take part. The consenting subjects were randomly allocated to either an intervention group (unsupervised PFMT) or a control group (lecture with no PFMT). Baseline and 12-week assessment of both groups was carried out for the primary outcome using the validated Arabic version of the International Consultation on Incontinence Questionnaire (ICIQ)-short form and the secondary outcome by blinded measures of pelvic floor muscle (PFM) strength using the modified Oxford grading system (MOGS), endurance, and perineometer. RESULTS A total of 73 subjects were included in the study. They were randomly divided into two groups. Both groups were similar at the baseline in terms of sociodemographic characteristics, ICIQ score, and PFM strength. At the 12-weeks assessment, there was a significant difference in the ICIQ score (P < .001) between the intervention group and the control one. There was no statistical difference between the two groups in MOGS, endurance, or perineometer values. CONCLUSIONS The home-based PFMT is an effective treatment in reducing the severity of symptoms and improving the QOL in women with SUI.

Abstract
INTRODUCTION AND HYPOTHESIS As noted in the 6th International Consultation on Incontinence (ICI) chapter "Initial Management of Urinary Incontinence in Women" recommendations call for including physiotherapy as a first-line therapy. METHODS Building on this, checking available scientific evidence and using the International Classification of Functioning, Disabilities and Health, the following represents a holistic physiotherapist approach for initial evaluation of the health problem of urinary incontinence. RESULTS This paper proposes a teaching module for every relevant health care professional dealing with the assessment of adult female urinary incontinence, focusing on optimal patient selection and appropriate treatment choice. CONCLUSION The assessment stage involves the explicit decision as to whether "physiotherapy" is the treatment indicated for the patient, based on the findings of the physiotherapy assessment and supplemented by any medical information that accompanied the referral and evaluation.

Abstract
AIM To measure the neuromuscular activation of the pelvic floor and abdominal muscles concurrently with vaginal closure forces induced during a hypopressive exercise (HE) and to identify the contribution of the HEs sequences (posture and maneuver) in the muscle's activation. METHODS A cross-sectional study design was employed. Sixty-six women who had participated in a physical therapy program focused on HEs were recruited. Pelvic floor muscle (PFM) activation was measured using surface electromyography (sEMG) in supine and in the orthostatic position, and vaginal closure force was measured through vaginal dynamometry in supine. Activation of the abdominal, gluteal, and hip adductor muscles was measured using sEMG. Maximum effort voluntary contractions (MVCs) of the PFMs and reference contractions of the abdominal and hip muscles were acquired for normalization purposes. A HE was then performed in a supine position with one leg raised, then in an orthostatic position. RESULTS During the supine HE, the peak PFM sEMG amplitude was 74.4% to 86.5% (49.6%-109.6%) of MVC, the peak vaginal closure force was between 51.2% and 55.7% (95.5%-382.9%) of MVC, and the muscles of the lateral abdominal wall were activated between 25.4% and 35.3% of the reference contraction. During the orthostatic HE, PFM activation was 61.4% (40.1%-105.6%) of MVC, and the lateral abdominal wall muscles contracted at 22.8% of the reference activation level. CONCLUSIONS The PFMs, abdominal, gluteal, and adductor muscles are activated during the performance of a HE. The activation level of the PFMs and abdominal muscles is likely insufficient to result in strength gains; however, they could have an endurance effect.

Abstract
OBJECTIVES To determine intra- and interrater reliability and agreement for ultrasound measurements of pelvic floor muscle contraction and to assess the correlation between ultrasound and vaginal palpation. We also aimed to develop an ultrasound scale for assessment of pelvic floor muscle contraction. METHODS This was a cross-sectional study of 195 women scheduled for stress urinary incontinence (n = 65) or prolapse (n = 65) surgery or who were primigravid (n = 65). Pelvic floor muscle contraction was assessed by vaginal palpation using the Modified Oxford Scale (MOS) and by two- and three-dimensional (2D/3D) transperineal ultrasound. Proportional change in 2D and 3D levator hiatal anteroposterior (AP) diameter and 3D levator hiatal area between rest and contraction were used as measures of pelvic floor muscle contraction. One rater repeated all ultrasound measurements on stored volumes, which were used for intrarater reliability and agreement analysis, and three independent raters analyzed 60 ultrasound volumes for interrater reliability and agreement analysis. Reliability was assessed using the intraclass correlation coefficient (ICC) and agreement using Bland-Altman analysis. Tomographic ultrasound was used to identify women with major levator injury. Spearman's rank correlation coefficient (rS ) was used to assess the correlation between ultrasound measurements of pelvic floor muscle contraction and MOS score. The proportion of women allocated to each category of muscle contraction (absent, weak, moderate or strong) by palpation was used to determine the cut-offs for the ultrasound scale. RESULTS Intrarater ICC was 0.81 (95% CI, 0.74-0.85) for proportional change in 2D levator hiatal AP diameter. Interrater ICC was 0.82 (95% CI, 0.72-0.89) for proportional change in 2D AP diameter, 0.80 (95% CI, 0.69-0.88) for proportional change in 3D AP diameter and 0.72 (95% CI, 0.56-0.83) for proportional change in hiatal area. The prevalence of major levator injury was 22.6%. The strength of correlation (rS ) between ultrasound measurements and MOS score was 0.52 for 2D AP diameter, 0.62 for 3D AP diameter and 0.47 for hiatal area (P < 0.001 for all). On the ultrasound contraction scale, proportional change in 2D levator hiatal AP diameter of < 1% corresponds to absent, 2-14% to weak, 15-29% to normal and > 30% to strong contraction. CONCLUSIONS Ultrasound seems to be an objective and reliable method for evaluation of pelvic floor muscle contraction. Proportional change in 2D levator hiatal AP diameter had the highest ICC and moderate correlation with MOS score assessed by vaginal palpation, and we constructed an ultrasound scale for assessment of pelvic floor muscle contraction based on this measure.

Abstract
AIMS Evaluate the intra- and inter-rater reliability of maximal voluntary contraction (MVC) of pelvic floor muscle (PFM) assessment by unidigital and bidigital vaginal palpation. As a secondary aim, evaluate the construct validity of vaginal palpation and a manometer. METHODS A total of 120 women were recruited and allocated into three groups according to age (group 1 [G1]: 18-35; G2: 36-59; G3: ≥60 years). Examiner A conducted an interview and examiners B and C performed evaluations of PFM function using both unidigital and bidigital vaginal palpation. Seven to 10 days later, examiner B repeated both types of vaginal palpation and measured the MVC pressure with a Peritron. Reliability was analyzed using Cohen's linear weighted Kappa (κw ). The construct validity was calculated using the Spearman's correlation (rs ). RESULTS Intra-rater reliability of unidigital and bidigital palpation was κw = 0.75 and κw = 0.58 in G1, κw = 0.59 and κw = 0.73 in G2, and κw = 0.79 and κw = 0.86 in G3, respectively. Inter-rater reliability of unidigital and bidigital palpation was κw = 0.52 and κw = 0.48 in G1, κw = 0.47 and κw = 0.52 in G2, and κw = 0.50 and κw = 0.64 in G3, respectively. Spearman's correlation coefficients were significant at rs = 0.79 and rs = 0.80 for unidigital and bidigital vaginal palpation, respectively. CONCLUSIONS Unidigital or bidigital vaginal palpation were indicated to evaluate G1 and G2 but bidigital palpation was more reliable in G3 when two examiners performed the evaluation. For the assessment conducted by one examiner, unidigital palpation was more reliable in G1 while bidigital palpation was more reliable in G2 and G3. Both unidigital and bidigital palpation have high measures of validity.

Abstract
A well-functioning pelvic floor muscle plays an important role in maintaining urinary continence. The aim of this study was to describe and compare the intravaginal pressure profile using a multisensor device along the vaginal length in women with and without urinary incontinence (UI), while performing pelvic floor muscle tasks. Fifty-four adult pre-menopausal women (31 continent and 23 incontinent) participated in this cross-sectional observational cohort study. The intravaginal pressure profile was assessed at rest, during maximum and sustained pelvic floor muscle contractions, using the Pliance® multisensor device. Between-group comparisons were performed considering the overall pressure and the pressure profile of 10-subregions along the vaginal length. In the overall pressure assessment, women with UI presented lower pressures at rest, similar pressures during maximum contraction and lower capacity to maintain pressure during sustained contraction compared to those in the continent group. The pressure profile assessment showed between-group differences that were consistent throughout tasks, with the incontinent group presenting lower pressures than the continent group, specifically in the mid-vaginal length, around 3-4 cm from the vaginal opening. We observed consistent deficits in pressure generation in incontinent compared to continent women, precisely in the region of the pelvic floor muscles. With this protocol and novel instrument, we obtained a reliable and consistent intravaginal pressure profile of continent and incontinent women. This approach could assist clinicians in the assessment of pelvic floor muscle function and foster a better understanding of the urinary incontinence mechanism.

Abstract
AIMS To test the reliability and validity of intravaginal pressure measurements acquired during pelvic floor muscle (PFM) tasks in different body positions using the FemFit®, a new intravaginal pressure device. METHODS Twenty healthy adult women participated in this study. Two assessment sessions were conducted. Intravaginal pressure measurements using the FemFit® were repeated during PFM contraction and straining maneuvers while lying and standing. Maximal intravaginal pressures were collated and compared within and between sessions. They were also correlated to maximal force measurements obtained by dynamometry and vaginal digital palpation. Test-retest reliability was assessed using intraclass correlation coefficient, standard error of measurement and Bland-Altman plots. The validity of the pressure measurements was assessed using Pearson's correlation (dynamometry) and Spearman's rho (palpation). RESULTS This test-retest study indicate excellent reliability for PFM contraction and straining maneuver both in lying and standing, within and between sessions. For the straining maneuver while standing, increased variability was suggested by a wider limit of agreement on Bland-Altman plots (spanning 31.3 to 43.3mm Hg). A significant moderate to strong correlation was found when comparing measurements of PFM contraction using the FemFit® and the dynamometer or the palpation (Pearson's coefficient = 0.72, P = .006; Spearman's rho = 0.68, P = .005, respectively). CONCLUSION Our research findings suggest that intravaginal pressures can be reliably measured during PFM contraction and straining manoeuver while lying and standing, using the FemFit® device, both within and between sessions. A moderate to strong correlation between the FemFit® pressure and the force measurements obtained by dynamometry or palpation reinforce the validity of measurements.

Abstract
Introduction According to the International Urogynecological Association and International Continence Society people with normal pelvic floor muscle function should have the ability to voluntarily and involuntarily contract and relax these muscles. However, many women are unaware of their pelvic floor, and it is estimated that about 30–50% do not know how to actively contract these muscles. Within this context, therapeutic strategies to improve pelvic floor muscle strength and function are particularly relevant. Aims To compare the use of an intravaginal vibratory stimulus (IVVS) versus intravaginal electrical stimulation (IVES) on pelvic floor muscle functionality in women with pelvic floor dysfunctions who cannot voluntarily contract these muscles. Materials and methods Randomized clinical trial performed at a tertiary care hospital from June 2016 to September 2017. The sample comprised adult women with pelvic floor dysfunction who were unable to contract their pelvic floor muscles voluntarily. Women with latex allergy or other allergies in the pelvic region, vaginal or urinary tract infection, gynecological cancer, significant pain on palpation, or pelvic floor training over the preceding 6 months were excluded. After baseline assessment, women that met the inclusion criteria were randomized to receive once-weekly 20-minute sessions of IVVS or IVES for 6 weeks. Results Twenty-one women were randomly assigned to each group; 18 completed the IVVS and 17 completed the IVES protocols. The IVVS group presented a significant increase in PFM strength in relation to the IVES group (p = 0.026). There was a significant interaction between time and type of intervention for the same variable (p = 0.008) in the IVVS group. Conclusion Both techniques were beneficial, but IVVS was significantly superior to IVES in improving pevic floor muscle strength. Additional studies are warranted to consolidate the utility of IVVS as a treatment modality for pelvic floor dysfunction.

Abstract
BACKGROUND AND OBJECTIVE A growing body of evidence indicates that a non-invasive erbium yttrium-aluminum-garnet (Er:YAG) laser may be an effective and highly tolerable treatment for stress urinary incontinence (SUI) in women. The primary objective was to identify pre-intervention predictors of short-term Er:YAG outcomes. The secondary objective was to identify patient segments with the best Er:YAG laser treatment short-term outcomes. METHODS A prospective cohort study performed in 2016 at Ob/Gyn Clinic, Zagreb, Croatia, recruited 85 female patients who suffered from SUI. The intervention was performed with a 2940 nm wave length Er:YAG laser (XS Dynamis, Fotona, Slovenia). Outcomes were absolute change in the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI SF) and a relative decrease in ICIQ-UI score of ≥30% 2-6 months after the intervention. RESULTS Age and pre-intervention ICIQ-UI values were independent significant predictors of laser treatment efficacy for SUI. A decrease in ICIQ-UI score (minimum important difference, MID) of ≥30% was independently significantly associated with body mass index and ICIQ-UI values before the intervention. All patients with four or five positive predictors saw a clinically relevant decrease in ICIQ-UI of ≥30%. The total accuracy of the predictive model defined by the area under the curve was 0.83 (95%CI 0.74-0.91). At the cut-off ≥3 positive predictors, C-index was 0.80 (95%CI 0.71-0.90), positive predictive value was 0.97 (95%CI 0.87-0.99), and negative predictive value was 0.53 (95%CI 0.45-0.55). CONCLUSIONS A relevant decrease in ICIQ-UI (MID) of ≥30% can be predicted based on age, body mass index, average birth weight, perineometer squeeze duration, and ICIQ-UI scores before the intervention. The association between Q-tip test and treatment outcome was moderated by age. Q-tip was a significant predictor for patients between 44 and 53 years of age. The best results should be expected in younger women with a body mass index of ≤23.3, average birth weight of >3.6 kg, ICIQ-UI at a baseline of ≤10, and perineometer squeeze duration at a baseline of ≥3.51 seconds. The critical age for Er:YAG laser effect is 47.5 years. Lasers Surg. Med. © 2018 Wiley Periodicals, Inc.
