Investigating the role of the pelvic floor muscles in sexual function and sexual response: a systematic review and meta-analysis.

INTRODUCTION: The pelvic floor muscles (PFMs) have been suggested to play a key role in sexual function and response in women. However, syntheses of the evidence thus far have been limited to interventional studies in women with pelvic pain or pelvic floor disorders, and these studies have failed to fully capture the involvement of the PFMs in a broader population. AIM: We sought to appraise the evidence regarding the role of the PFMs in sexual function/response in women without pelvic pain or pelvic floor disorders. More specifically, we examined the following: (1) effects of treatment modalities targeting the PFMs on sexual function/response, (2) associations between PFM function and sexual function/response, and (3) differences in PFM function between women with and those without sexual dysfunction. METHODS: We searched for all available studies in eight electronic databases. We included interventional studies evaluating the effects of PFM modalities on sexual outcomes, as well as observational studies investigating the association between PFM function and sexual outcomes or the differences in PFM function in women with and those without sexual dysfunction. The quality of each study was assessed using the Mixed Methods Appraisal Tool. Estimates were pooled using random-effects meta-analyses whenever possible, or a narrative synthesis of the results was provided. MAIN OUTCOMES: The main outcomes were sexual function (based on a questionnaire)/sexual response (based on physiological test), and PFM function (assessment of the PFM parameters such as strength and tone based on various methods). RESULTS: A total of 33 studies were selected, including 14 interventional and 19 observational studies, most of which (31/33) were deemed of moderate or high quality. Ten out of 14 interventional studies in women with and without sexual dysfunctions showed that PFM modalities had a significant effect on sexual function. Regarding the observational studies, a meta-analysis revealed a significant moderate association between PFM strength and sexual function (r = 0.41; 95% CI, 0.08-066). Of the 7 observational studies performed to assess sexual response, all showed that the PFMs were involved in arousal or orgasm. Conflicting results were found in the 3 studies that evaluated differences in PFM function in women with and those without sexual dysfunction. CLINICAL IMPLICATIONS: Our results highlight the contribution of the PFMs in sexual function/response. STRENGTHS AND LIMITATIONS: One strength of this review is the inclusion of a broad range of study designs and outcomes, allowing a thorough synthesis of evidence. However, interpretations of these data should consider risk of bias in the studies, small sample sizes, and the absence of control/comparison groups. CONCLUSION: The findings of this review support the involvement of the PFMs in sexual function/response in women without pelvic pain or pelvic dysfunction. Well-designed studies should be performed to further investigate PFM modalities as part of the management of sexual dysfunction.

Guideline No. 445: Management of Chronic Pelvic Pain.

OBJECTIVE: To provide evidence-based recommendations for the management of chronic pelvic pain in females. TARGET POPULATION: This guideline is specific to pelvic pain in adolescent and adult females and excluded literature that looked at pelvic pain in males. It also did not address genital pain. BENEFITS, HARMS, AND COSTS: The intent is to benefit patients with chronic pelvic pain by providing an evidence-based approach to management. Access to certain interventions such as physiotherapy and psychological treatments, and to interdisciplinary care overall, may be limited by costs and service availability. EVIDENCE: Medline and the Cochrane Database from 1990 to 2020 were searched for articles in English on subjects related to chronic pelvic pain, including diagnosis, overlapping pain conditions, central sensitization, management, medications, surgery, physiotherapy, psychological therapies, alternative and complementary therapies, and multidisciplinary and interdisciplinary care. The committee reviewed the literature and available data and used a consensus approach to develop recommendations. Only articles in English and pertaining to female subjects were included. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations). INTENDED AUDIENCE: Family physicians, gynaecologists, urologists, pain specialists, physiotherapists, and mental health professionals. TWEETABLE ABSTRACT: Management of chronic pelvic pain should consider multifactorial contributors, including underlying central sensitization/nociplastic pain, and employ an interdisciplinary biopsychosocial approach that includes pain education, physiotherapy, and psychological & medical treatments. SUMMARY STATEMENTS: RECOMMENDATIONS.

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

BACKGROUND: 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. AIM: To systematically review the literature comparing PFM tone in women with and without PNCPP. METHODS: 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 ≥18 years 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. OUTCOMES: Resting PFM tone parameters, including myoelectrical activity, resistance, morphometry, stiffness, flexibility, relaxation, and intravaginal pressure, measured by any clinical examination method or tool. RESULTS: 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. CLINICAL IMPLICATIONS: Available evidence suggests that women with PNCPP have increased PFM tone, which could be targeted by treatments. STRENGTHS AND LIMITATIONS: 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. CONCLUSION: 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.

Are pelvic pain and increased pelvic floor muscle tone associated in women with persistent noncancer pelvic pain? A systematic review and meta-analysis.

BACKGROUND: The association between pelvic pain and pelvic floor muscle (PFM) tone in women with persistent noncancer pelvic pain (PNCPP) is unclear. AIM: To synthesize the evidence of the association between pelvic pain and PFM tone in women with PNCPP. METHODS: A systematic review was conducted via MEDLINE, Emcare, Embase, CINAHL, PsycINFO, and Scopus to identify relevant studies. Studies were eligible if pelvic pain and PFM tone outcome measures were reported among women aged >18 years. The National Heart, Lung, and Blood Institute's Quality Assessment Tool for Observational Cohort and Cross-sectional Studies was used to assess study quality. Studies were pooled by assessment of PFM tone via a random effects model. Associations between the presence of pelvic pain and PFM tone were assessed with odds ratio (OR), while linear associations were assessed with Pearson or Spearman correlation. OUTCOMES: Pelvic pain measures (intensity, threshold, and frequency) and resting PFM tone in women with PNCPP, as evaluated by any clinical assessment method or tool. RESULTS: Twenty-four studies were included in this review. The presence of pelvic pain was significantly associated with increased PFM tone as assessed by digital palpation (OR, 2.85; 95% CI, 1.66-4.89). Pelvic pain intensity was inversely but weakly associated with PFM flexibility when evaluated through dynamometry (r = -0.29; 95% CI, -0.42 to -0.17). However, no significant associations were found between pelvic pain and PFM tone when measured with other objective assessment methods. CLINICAL IMPLICATIONS: Pelvic pain and increased PFM tone may not be directly associated; alternatively, a nonlinear association may exist. A range of biopsychosocial factors may mediate or moderate the association, and clinicians may need to consider these factors when assessing women with PNCPP. STRENGTHS AND LIMITATIONS: This review was reported according to the PRISMA guidelines. All possible findings from relevant theses and conference abstracts were considered in our search. However, nonlinear associations between pelvic pain and increased PFM tone were not assessed as part of this review. CONCLUSION: Pelvic pain may be linearly associated with increased PFM tone and decreased PFM flexibility when measured with digital palpation or dynamometry; however, this association was not observed when other aspects of PFM tone were assessed through objective methods. Future studies are required using robust assessment methods to measure PFM tone and analyses that account for other biopsychosocial factors that may influence the association.

Gynecological Cancer Survivors' Experiences of Dyspareunia and Factors Influencing Care-Seeking Behavior: A Qualitative Study.

Pain during sexual intercourse, also called dyspareunia, affects most women after treatment for gynecological cancer. Previous work adopted a biomedical approach to depict dyspareunia in this population, which provided a narrow perspective of this condition. Taking into account women's experiences of dyspareunia and the factors influencing their care-seeking behaviors would provide insight to improve care in the context of gynecological cancer. The aim of this study was to describe gynecological cancer survivors' experiences of dyspareunia and factors influencing care-seeking behavior. A qualitative study was performed with 28 gynecological cancer survivors with dyspareunia. Individual telephone interviews were conducted based on the Common-Sense Model of Self-Regulation. Interviews were recorded and transcribed for analysis using the interpretative description framework. Concerning their experience, participants reported the oncological treatments as the primary cause of dyspareunia. Loss of libido, lower vaginal lubrication, and smaller vaginal cavity were described as being linked with dyspareunia. Women explained how dyspareunia and these changes had led them to engage less in, and even interrupt, sexual activity. They expressed that they were distressed, felt less of a woman, and experienced low control and/or self-efficacy. Regarding the factors influencing women's care-seeking behaviors, participants emphasized that they were provided with insufficient information and support. Balancing priorities, denial or reluctance, misbeliefs, resignation and acceptance, and negative emotions were reported as barriers, whereas acknowledgement of sexual dysfunction, desire for improvement, awareness of treatment possibilities, willingness to undertake treatment and treatment acceptability were reported as facilitators to seeking care. Findings suggest that dyspareunia is a complex and impactful condition after gynecological cancer. While this study highlights the importance of alleviating the burden of sexual dysfunction in cancer survivors, it identified factors that should be considered in the provision of services to improve care.

Acceptability of multimodal pelvic floor physical therapy to treat dyspareunia after gynecological malignancies: a qualitative study of women's views and experiences.

INTRODUCTION AND HYPOTHESIS: Multimodal pelvic floor physical therapy (PFPT) is recommended after gynecological malignancies to treat dyspareunia. However, data to strongly support its implementation in the cancer care continuum are lacking. The aim of this study was to explore the views and experiences of gynecological cancer survivors with dyspareunia regarding the acceptability of multimodal PFPT. METHODS: This qualitative study was conducted with the participants (n = 28) of a study investigating a 12-week multimodal PFPT treatment. Individual semi-structured telephone interviews served to collect qualitative data pertaining to women's views and experiences of the treatment they received. Interviews were recorded and transcribed for analysis using the interpretative description framework. RESULTS: Our cohort described the appropriateness of the treatment in terms of modalities, physical therapist, care delivery, and intensity (Theme 1). While the intensity was reported as demanding by a few, all participants stressed that it was relevant to see significant improvements (Theme 2). In addition to the treatment characteristics and women's beliefs and attitudes, noticing the treatment effects motivated their participation (Theme 2). Women expressed being highly satisfied with the treatment based on their positive experiences and the balance between their efforts and the results they obtained (Theme 3). As a result, they all recommended this treatment (Theme 3). CONCLUSIONS: This is the first study to examine the acceptability of multimodal PFPT in the context of gynecological malignancies. This treatment was found acceptable and can be offered to gynecological cancer survivors.

Does the addition of electrical stimulation or kinesiotherapy improve outcomes of amitriptyline treatment for women with vulvodynia? A randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: Women diagnosed with provoked vulvodynia frequently report a great deal of frustration in achieving symptomatic relief. Physical therapy and drug treatment are among the interventions most indicated by guidelines; however, whether those modalities are effective when combined remains unclear. The objective was to evaluate the effectiveness of adding a physical therapy modality compared with amitriptyline alone for the treatment of vulvodynia. METHODS: Eighty-six women with vulvodynia were randomized to (G1) 25 mg amitriptyline, once a day (n=27), (G2) amitriptyline + electrical stimulation therapy (n=29) or (G3) amitriptyline + kinesiotherapy (n=30). All treatment modalities were administered for 8 weeks. The primary endpoint was the reduction in vestibular pain. Secondary measurements focused on sexual pain, frequency of vaginal intercourse, Friedrich score, and overall sexual function. Data were analyzed using intention-to-treat. RESULTS: All treatment modalities resulted in a significant decrease in vestibular pain (p<0.001), sexual pain (p<0.05), Friedrich score (p<0.001), and an increase in the frequency of sexual intercourse (p<0.05). G3 was more effective than G1 at reducing sexual pain (G1: 5.3±3.3 vs G3: 3.2±2.7; p=0.01) and at improving sexual function (G1: 18.8±9.8 vs G3: 23.9±7.8; p=0.04). CONCLUSION: Kinesiotherapy and electrotherapy additions to amitriptyline administration as well as amitriptyline alone, were effective at improving vestibular pain in women with vulvodynia. Women receiving physical therapy had the greatest improvement in sexual function and frequency of intercourse at post-treatment and follow-up.

Validation of shear wave elastography as a noninvasive measure of pelvic floor muscle stiffness.

OBJECTIVES: To investigate the validity of shear wave elastography (SWE) as a measure of stiffness of the puborectalis muscle by examining: (1) the relationship between puborectalis muscle stiffness and pelvic floor muscle (PFM) activation at different intensities; and (2) the relationship between puborectalis stiffness and pelvic floor morphometry during contractions at different intensities. METHODS: Fifteen healthy asymptomatic women performed 6-s isometric PFM contractions at different intensities (0, 10%, 20%, 30%, 50%, 75%, and 100% of maximal voluntary contraction) guided by intravaginal electromyography (EMG). Stiffness of the puborectalis muscle was measured using SWE by calculating the average shear modulus in regions of interest that contained puborectalis muscle fibers parallel to the transducer. Pelvic floor morphometry was assessed in the mid-sagittal plane using transperineal B-mode ultrasound imaging. Shear modulus, EMG (root mean square amplitude) and pelvic floor morphometry parameters were normalized to the value recorded during maximal voluntary contraction. To assess the relationship between stiffness and pelvic floor activation/morphometry, coefficient of determination (r2 ) was calculated for each participant and a group average was computed. RESULTS: Shear modulus and EMG were highly correlated (average r2 ; left 0.90 ± 0.08, right 0.87 ± 0.15). Shear modulus also strongly correlated with bladder neck position (x-axis horizontal coordinates relative to the pubic symphysis), anorectal rectal angle and position, levator plate angle, and antero-posterior diameter of the levator hiatus (average r2 : range 0.62-0.78). CONCLUSIONS: These findings support the validity of SWE to assess puborectalis muscle stiffness in females. Stiffness measures were strongly associated with PFM EMG and pelvic floor morphometry and may be used to indirectly assess the level of activation of the puborectalis muscle without the use of more invasive techniques. By overcoming limitations of current assessment tools, this promising noninvasive and real-time technique could enable important breakthrough in the pathophysiology and management of pelvic floor disorders.

Clitoral blood flow using color Doppler ultrasonography in women with and without provoked vestibulodynia.

INTRODUCTION AND HYPOTHESIS: To compare blood flow of the dorsal clitoral artery in women diagnosed with provoked vestibulodynia (PVD) and in healthy controls using color Doppler ultrasonography. We hypothesized that women with PVD would have a restricted blood flow compared to controls. METHODS: This cross-sectional study evaluated the function of the dorsal clitoral artery through the spectral wave analysis of color Doppler ultrasonography (US) in 20 women diagnosed with PVD according to Friedrich's criteria and 21 healthy controls. Participants were evaluated during their follicular phase and were asked to abstain from sexual activities 24 ho prior the examination. Assessment was performed by an assessor blinded to participant diagnosis, in the morning after a 10-min rest period in a supine lying position in a room with temperature set at 22 °C. Measurements of the peak systolic velocity (PSV), time-averaged maximum velocity (TAMX), end-diastolic velocity (EDV), pulsatility (PI) and resistance index (RI) were performed at rest considering the mean value of three consecutive waveforms. RESULTS: Women with PVD and healthy controls did not present any statistically different baseline characteristics. Participants with PVD presented higher values of Doppler-US PSV, TAMX, EDV and RI compared to controls (p ≤ 0.05), which are suggestive of a decrease in blood flow. However, non-significant difference was found regarding PI values between the two groups (p > 0.05). CONCLUSION: Our findings revealed decreased peripheral tissue perfusion in women with PVD compared to healthy controls using color Doppler US, based on the alteration of four of the five assessed data of US parameters.

Multimodal physical therapy versus topical lidocaine for provoked vestibulodynia: a multicenter, randomized trial.

BACKGROUND: Provoked vestibulodynia is the most common subtype of chronic vulvar pain. This highly prevalent and debilitating condition is characterized by acute recurrent pain located at the entry of the vagina in response to pressure application or attempted vaginal penetration. Although physical therapy is advocated as a first-line treatment for provoked vestibulodynia, evidence supporting its efficacy is scarce. OBJECTIVE: The purpose of this study was to establish the efficacy of multimodal physical therapy compared with topical lidocaine, a frequently used first-line treatment. STUDY DESIGN: We conducted a multicenter, parallel-group, randomized clinical trial in women diagnosed as having provoked vestibulodynia recruited from the community and 4 Canadian university hospitals. Women were randomly assigned (1:1) to receive either weekly sessions of physical therapy or overnight topical lidocaine (5% ointment) for 10 weeks. Randomization was stratified by center using random permuted blocks from a computer-generated list managed by an independent individual. Physical therapy entailed education, pelvic floor muscle exercises with biofeedback, manual therapy, and dilation. Assessments were conducted at baseline, posttreatment, and 6-month follow-up. Outcome assessors, investigators, and data analysts were masked to allocation. The primary outcome was pain intensity during intercourse evaluated with the numeric rating scale (0-10). Secondary outcomes included pain quality (McGill-Melzack Pain Questionnaire), sexual function (Female Sexual Function Index), sexual distress (Female Sexual Distress Scale), satisfaction (numeric rating scale of 0-10), and participants' impression of change (Patient Global Impression of Change). Intention-to-treat analyses were conducted using piecewise linear-growth models. RESULTS: Among 212 women who were recruited and randomized, 201 (95%) completed the posttreatment assessment and 195 (92%) completed the 6-month follow-up. Multimodal physical therapy was more effective than lidocaine for reducing pain intensity during intercourse (between-group pre-post slope difference, P<.001; mean group postdifference, 1.8; 95% confidence interval, 1.2-2.3), and results were maintained at 6-month follow-up (mean group difference, 1.8; 95% confidence interval, 1.2-2.5). The physical therapy group also performed better than the lidocaine group in all secondary outcomes (pain quality, sexual function, sexual distress, satisfaction, and participants' impression of change) at posttreatment and 6-month follow-up. Moreover, the changes observed after physical therapy were shown to be clinically meaningful. Regarding participants' impression of change, 79% of women in the physical therapy group reported being very much or much improved compared with 39% in the lidocaine group (P<.001). CONCLUSION: The findings provide strong evidence that physical therapy is effective for pain, sexual function, and sexual distress and support its recommendation as the first-line treatment of choice for provoked vestibulodynia.

A Prospective Single-Arm Study Evaluating the Effects of a Multimodal Physical Therapy Intervention on Psychosexual Outcomes in Women With Dyspareunia After Gynecologic Cancer.

BACKGROUND: Dyspareunia affects most women after treatment for gynecologic malignancies. However, to date, evidence-based interventions remain limited and no study has examined the effects of multimodal physical therapy on psychosexual outcomes in these patients. AIM: To assess the effects of multimodal physical therapy on psychosexual outcomes including sexual distress, body image concerns, pain anxiety, pain catastrophizing, pain self-efficacy and depressive symptoms in women with dyspareunia after treatment for gynecologic malignancies. METHODS: Thirty-one gynecologic cancer survivors with dyspareunia enrolled in this prospective single-arm interventional study. The participants undertook 12 weekly sessions of physical therapy incorporating education, pelvic floor muscle exercises with biofeedback, manual therapy and home exercises. Outcome measures were evaluated pre- and post-treatment. Paired t-tests were conducted to investigate the changes from pre-treatment (P-value Ë‚ 0.05) while effect sizes (Cohen's d) were calculated to measure the magnitude of the change. MAIN OUTCOME MEASURES: Sexual distress (Female Sexual Distress Scale-Revised), body image concerns (Body Image Scale), pain anxiety (Pain Anxiety Symptoms Scale), pain catastrophizing (Pain Catastrophizing Scale), pain self-efficacy (Painful Intercourse Self-Efficacy Scale) and depressive symptoms (Beck Depression Inventory-II). RESULTS: Significant changes were found from pre- to post-treatment for all psychosexual outcomes. Women reported reductions in sexual distress (P Ë‚ 0.001, d = 1.108), body image concerns (P Ë‚ 0.001, d = 0.829), pain anxiety (P Ë‚ 0.001, d = 0.980), pain catastrophizing (P Ë‚ 0.001, d = 0.968) and depression symptoms (P = 0.002, d = 0.636) with an increase in pain self-efficacy (P Ë‚ 0.001, d ≥ 0.938) following the intervention. CLINICAL IMPLICATIONS: The results suggest that multimodal physical therapy significantly improves sexual distress, body image concerns, pain anxiety, pain catastrophizing, pain self-efficacy and depressive symptoms in our sample of women with dyspareunia after treatment for gynecologic malignancies. The medium to large effect sizes obtained with the high proportion of women presenting meaningful changes according to the known minimal clinically important difference or clinical cut-off underlines the significance of these effects. STRENGTHS & LIMITATIONS: The current study used validated questionnaires to assess the psychosexual outcomes of a well-designed physical therapy intervention using multiple modalities to address the multifaceted aspect of dyspareunia in cancer survivors. This study did not include a control group, which may limit drawing definitive conclusions. CONCLUSION: Findings showed that multimodal physical therapy yielded significant improvements in psychosexual outcomes in gynecologic cancer survivors with dyspareunia. A randomized controlled trial is indicated to confirm these results. Cyr M-P, Dumoulin C, Bessette P, et al.

Pelvic floor morphometrical and functional changes immediately after pelvic floor muscle training and at 1-year follow-up, in older incontinent women.

AIMS: To compare the effects of group-based and individual physiotherapy for stress or mixed urinary incontinence (UI) on pelvic floor morphometry, pelvic floor muscle (PFM) function, and related self-efficacy, immediately after treatment and at 1 year. METHODS: This is a planned secondary analysis of the group rehabilitation or individual physiotherapy study, an assessor-blinded, randomized, noninferiority trial. Eligible participants included 362 community-dwelling older women with symptoms of stress/mixed UI. After learning how to contract PFMs, participants completed 12 weeks of PFM training, either individually (one-on-one) or as part of a group (eight women). Pelvic floor transperineal ultrasound volumes (morphometry), PFM intravaginal dynamometric data (function), and self-efficacy in performing PFM exercises were acquired at baseline, posttreatment, and at 1 year. RESULTS: Groups were comparable at all time points. Immediately posttreatment, both groups demonstrated significant changes in pelvic floor morphometry during coughs, and in PFM function during contractions and coughs. Participants also reported improved self-efficacy in performing PFM exercises. Results were sustained at 1 year. When participants coughed, pelvic floor structures were better supported (reflected by less caudal movement of the puborectalis sling and a smaller opening of the levator hiatus) in a pattern consistent with the "knack" strategy. Furthermore, both interventions resulted in stronger, faster, more coordinated, and more endurant PFMs. CONCLUSION: In older women with stress or mixed UI, both individual and group-based PFM training resulted in comparable improvements in overall PFM function, pelvic floor morphometry during coughs, and related self-efficacy in performing PFM exercises, which were sustained at 1 year.

An International Continence Society (ICS) report on the terminology for pelvic floor muscle assessment.

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.

Feasibility, acceptability and effects of multimodal pelvic floor physical therapy for gynecological cancer survivors suffering from painful sexual intercourse: A multicenter prospective interventional study.

OBJECTIVES: Painful sexual intercourse (dyspareunia) is a distressing condition affecting a large proportion of gynecological cancer survivors, yet treatments remain limited and poorly studied. This multicenter prospective interventional study examined the feasibility, acceptability and effects of multimodal pelvic floor physical therapy in gynecological cancer survivors with dyspareunia. METHODS: Thirty-one endometrial and cervical cancer survivors with dyspareunia participated in 12 weekly 60-min physical therapy sessions combining education, manual therapy, pelvic floor muscle exercises using biofeedback and home exercises, which included the use of a dilator. The adherence rate to home exercises (≥80%), the attendance rate at physical therapy sessions (≥80% of participants attending ≥10 sessions) and the dropout rate (˂15%) served as feasibility and acceptability outcomes and benchmarks. Pain intensity, pain quality, sexual function, pelvic floor dysfunction symptoms and quality of life were measured at baseline and post-treatment. Treatment satisfaction and participants' perceived improvement were also assessed. RESULTS: The adherence rate was 88% (SD 10), 29/31 (94%) women attended ≥10 treatment sessions, and the dropout rate was 3%. Moreover, women experienced significant improvements in all outcomes after the intervention (p ≤ 0.044). They also reported being highly satisfied with the treatment (9.3/10 (SD 1.2)), and 90% of them were very much or much improved. CONCLUSIONS: Our findings support the feasibility and acceptability of multimodal pelvic floor physical therapy for gynecological cancer survivors with dyspareunia. The intervention also led to significant improvements in pain, sexual function, pelvic floor dysfunction symptoms and quality of life. A randomized controlled trial is needed to confirm these results.

Efficiency and Cost: E-Recruitment Is a Promising Method in Gynecological Trials.

BACKGROUND: Recruitment of participants is crucial to the success of any trial as it can have a major impact on study costs, the duration of the study itself, and, more critically, trial failure. Given that vulvodynia particularly affects young women, the use of social media and e-recruitment could prove efficient for enrollment. AIM: To compare the efficiency, effectiveness, and cost-effectiveness of three different recruitment methods. METHODS: The comparison data were collected as part of a bicentric randomized controlled trial evaluating the efficacy of physiotherapy in comparison with topical lidocaine in 212 women suffering from provoked vestibulodynia. The recruitment methods included: (i) conventional methods (eg, posters, leaflets, business cards, newspaper ads); (ii) health professional referrals, and (iii) e-recruitment (eg, Facebook ads and web initiatives). Women interested in participating were screened by telephone for eligibility criteria and were assessed by a gynecologist to confirm their diagnosis. Once included, structured interviews were undertaken to describe their baseline characteristics. MAIN OUTCOME MEASURES: The outcomes of this study were the recruitment efficiency (the number of patients screened/enrolled), recruitment effectiveness (the number of participants enrolled), cost-effectiveness (cost per enrolled participant), and retention rate, and baseline characteristics of participants were monitored for each method. RESULTS: The conventional methods (n = 101, 48%) were more effective as they allowed for greater enrollment of participants, followed by e-recruitment (n = 60, 28%) and health professional referrals (n = 33, 16%) (P < 0.007). Recruitment efficiency was found to be similar for e-recruitment and referrals (60/122 and 33/67, 49%, P = 0.055) but lower for conventional methods (101/314, 32%, P < 0.011). Nonsignificant differences were found between the three groups for baseline characteristics (P ≥ 0.189) and retention rate (91%, P ≥ 0.588). The average cost per enrolled participant was fairly similar for e-recruitment ($117) and conventional methods ($110) and lower for referrals ($60). CLINICAL IMPLICATIONS: Our results suggest that having a variety of recruitment methods is beneficial in promoting clinical trial recruitment without affecting participant characteristics and retention rates. STRENGTH & LIMITATIONS: Although recruitment methods were used concomitantly, this study gives an excellent insight into the advantages and limitations of recruitment methods owing to a large sample size. CONCLUSION: The study findings revealed that e-recruitment is a valuable recruitment method because of its comparable efficiency and cost-effectiveness to health professional referrals and conventional methods, respectively.

Assessment of the effects of autologous muscle-derived cell injections on urethral sphincter morphometry using 3D/4D ultrasound.

PURPOSE: The primary objective was to evaluate the effect of autologous muscle-derived cell (AMDC) injections on the urethral sphincter morphometry compared to placebo injections. Secondary aims were to explore the reduction of stress incontinence episode frequency (IEF) and factors associated with the efficacy of AMDC. METHODS: This prospective randomized-controlled study compared the urethral sphincter volumes of participants who had received either an intra-sphincteric injection of 4 cc AMDC in injection media or 4 cc placebo solution, using a transperineal 3D/4D ultrasound at baseline and at 12 months. The reduction of stress IEF on 3-day bladder diary and potential predictors at baseline for response to AMDC were assessed. RESULTS: Fifty-eight participants were included in the study. Compared to baseline, the mean total and external sphincter volumes increased significantly in both groups (respectively, p = 0.001 and p < 0.001 in the AMDC group, p < 0.001 and p = 0.005 in the placebo group) at 12 months. Both groups showed a significant reduction of stress IEF compared to baseline (p = 0.03 and p ≤ 0.001 for AMDC and placebo groups, respectively). There were no between-group differences regarding total and external sphincter volumes and reduction of stress IEF. A longer urethral length (p ≤ 0.001) and a larger external sphincter volume (p ≤ 0.05) were significantly associated with lower stress IEF. CONCLUSION: Significant increases of sphincter volumes as well as reduction of stress IEF occurred among the AMDC and placebo injection groups with no between-group differences at 12 months. A longer urethral length and a larger external sphincter volume at baseline were identified as potential predictors of AMDC injection response.

What do we really know about the role of caffeine on urinary tract symptoms? A scoping review on caffeine consumption and lower urinary tract symptoms in adults.

AIMS: The purpose of this scoping review was to map out the existing literature on caffeine intake and lower urinary tract symptoms (LUTS) in adults. METHODS: In this scoping review, we searched for all studies available until June 2019 in MEDLINE, Embase, CINAHL, Cochrane Central Register, PsycINFO, LILACS, LiSSa, Web of Science, and Joanna Briggs Institute electronic databases, in addition to a hand search of the bibliographies of all relevant articles and a gray literature search. Both intervention studies on the effects of caffeine reduction in adults with LUTS and observational studies on the association between caffeine intake and LUTS-related outcomes in adults were included and assessed for methodological quality by two independent reviewers. RESULTS: Fourteen intervention and 12 observational studies were included. Overall, there was a decrease in urgency episodes (level of evidence 2, grade of recommendation B) and nocturnal enuresis episodes (4, C) with caffeine reduction. Observational studies reported an unclear association between caffeine intake and LUTS-related outcomes. Most importantly, this present review highlighted high heterogeneity in the studied populations, caffeine measures, and reported outcomes. There was also unknown or high risk of bias in most identified studies. CONCLUSIONS: Caffeine reduction appears to reduce LUTS. Future studies on caffeine reduction interventions should target populations with urgency and urge urinary incontinence, which show the most promising results, and include valid and reliable measures of caffeine intake and LUTS. Finally, future studies should also use reporting guidelines to ensure lower risk of bias.

The effects of a strong desire to void on gait for incontinent and continent older community-dwelling women at risk of falls.

AIMS: The fall rate in urgency urinary incontinence (UUI) and mixed UI (MUI) older women is higher when compared with that of continent women. One hypothesis is that a strong desire to void (SDV) could alter gait parameters and therefore increase the risk of falls. The aim of this study was to investigate and compare the effect of SDV on gait parameters in UUI/MUI and continent older women who experienced falls. The secondary aim was to determine the relationship between UI severity and gait parameters in incontinent women. METHODS: A quasi-experimental pilot study was conducted with two groups of healthy community-dwelling women who experienced at least one fall in the last year: continent (n = 17; age: 74.1 ± 4.3) and UUI/MUI (n = 15; age: 73.5 ± 5.9). We recorded, analyzed, and compared spatiotemporal gait parameters for participants in each group with both SDV and no desire to void condition. RESULTS: A pattern of reduced velocity (P = 0.05) and stride width (P = 0.02) was observed in both groups with SDV. Incontinence severity was correlated with reduced velocity (rs = -0.63, P = 0.01), increased stance time (rs = 0.65, P = .01) and stance time variability (rs = 0.65, P = .01) in no desire to void condition and with reduced velocity (rs = -0.56, P = .03) and increased stride length variability (rs = 0.54, P = .04) in SDV condition. CONCLUSIONS: SDV reduced gait velocity and stride width regardless of continence status in older women at risk of falls. Further, UI severity in the UUI/MUI women was correlated to reduced gait velocity and increased variability. Our findings could explain the higher fall rate in this population.

Reliability of vulvar blood perfusion in women with provoked vestibulodynia using laser Doppler perfusion imaging and laser speckle imaging.

BACKGROUND: Microvascular assessment has become increasingly used in gynecology to better understand the pathophysiology of various vulvar conditions and to study sexual function. Alteration in blood perfusion of the vulvar area has been observed using laser technologies in women with provoked vestibulodynia (PVD), the leading cause of vulvar pain. However, no studies have thus far investigated the reliability of and agreement between lasers for evaluating vulvar blood perfusion. OBJECTIVES: The main objective was to investigate the between-session reliability of the laser Doppler perfusion imaging (LDPI) and laser speckle contrast imaging (LSCI) for assessing blood perfusion of the vulvar vestibule in women with PVD. Secondary aims were to evaluate the association and agreement between the two laser technologies. METHODS: Twenty-six women with PVD participated in the study. Blood perfusion of the vulvar vestibule was assessed with LDPI and LSCI during two sessions 2 to 4 weeks apart. Blood perfusion was analyzed in five specific areas of the vulvar vestibule: 1) 3 o'clock site, 2) 6 o'clock site, 3) 9 o'clock site, 4) central area (delimited by areas 1, 2 and 3), and 5) posterior fourchette. The reliability of the measurements of the two instruments was calculated with intraclass correlation coefficients (ICCs), standard errors of measurement (SEMs) and coefficients of variation (CVs). Paired t-tests were also computed to compare the CVs of each laser technology. The association and agreement between LDPI and LSCI measurements were evaluated by Pearson's correlation coefficients and Bland-Altman plots, respectively. RESULTS: Excellent reliability was found for LDPI (ICCs = 0.78-0.80, p < 0.001, SEMs = 16.1-47.9) and LSCI measurements (ICCs = 0.75-0.81, p ≤ 0.001, SEMs = 17.0-52.2) for all vulvar vestibule areas. However, CVs were significantly higher using LDPI (CVs = 15.1-19.8) when compared to LSCI (CVs = 7.0-11.6) for all areas (p ≤ 0.031), except for area 4 (p = 0.079). Significant correlations were found between LDPI and LSCI for all areas (r = 0.58-0.89, p ≤ 0.003). Bland-Altman plots revealed a systematic difference between LDPI and LSCI measurements. CONCLUSION: Findings show that both LDPI and LSCI measurements are reliable for assessing blood perfusion of the vulvar vestibule in women with PVD. The LSCI appears to be a more reliable measurement as it presents less variation than LDPI. Finally, although LDPI and LSCI measurements are related, the systematic difference observed between them makes it impossible to compare absolute units.
