To contract or not to contract: should we use pelvic floor muscle exercises in the treatment of dyspareunia

Pelvic floor physiotherapy incorporates pelvic floor muscle (PFM) exercises (PFMEs), i.e. various tasks involving contraction and relaxation. These are widely used as an integral part of conservative treatment for different pelvic health conditions (e.g. urinary incontinence). Currently, there is a debate about the adoption of PFMEs for pelvic pain conditions, specifically dyspareunia. The prevailing belief within both the physiotherapy community and wider social media platforms is that PFMEs for dyspareunia are not appropriate and may even be harmful. The aim of this study was to investigate the role of PFMEs in the treatment of dyspareunia, including an exploration of potential mechanisms through which these exercises may alter its symptoms. Specifically, the authors addressed the following questions: What is the rationale for PFMEs in dyspareunia? What are the documented side effects, if any? What are the outcomes following PFMEs? A list of relevant studies was compiled from extensive searches conducted for the purpose of other reviews performed by the authors, and additional, complementary searches utilizing a combination of keywords associated with dyspareunia, physiotherapy and PFMEs. The inclusion criteria were any studies discussing and investigating the use of PFMEs, such as (but not limited to) repeated contractions or hold contractions as a sole intervention or as part of multimodal treatment. Data were extracted and narratively synthesized to identify arguments advocating for and against PFMEs in the treatment of dyspareunia. Part of the narrative analysis included 10 studies involving women with different types of dyspareunia, such as vulvodynia, postpartum dyspareunia, dyspareunia related to menopause and dyspareunia in cancer survivors. Pelvic floor muscle exercises were implemented as a main intervention or as a part of multimodal physiotherapy. All of the studies reported positive results favouring interventions involving PFMEs across various outcomes, such as pain intensity, sexual function, symptom severity and inconvenience, and PFM morphometry and function. None of the studies reported any side effects following interventions incorporating PFMEs. These exercises may have multiple applications in the treatment of dyspareunia. It appears essential to consider PFMEs as a multifaceted intervention that can be adapted in various forms for diverse objectives that extend beyond simple strengthening. Contrary to prevailing beliefs, PFMEs have been widely incorporated in research studies that have reported positive outcomes and demonstrated the safety of the interventions implemented.

Physiotherapy management of acute perineal trauma: a patient satisfaction survey

Pelvic floor muscle (PFM) training is recommended in the immediate postpartum period because it can restore PFM function and prevent pelvic floor dysfunction. There are no national physiotherapy guidelines on how to deliver this intervention in the acute period. There is also no consensus on the need for outpatient follow-up to treat pelvic floor dysfunction that arises from perineal trauma, or as a preventative strategy in the long term. The aim of this study was to evaluate a current service provided for women with acute perineal trauma. The authors assessed patient satisfaction and compliance with physiotherapy advice, and identified preferences for future service development. One hundred and thirty patients completed satisfaction questionnaires after receiving inpatient physiotherapy treatment. Thirty consented to completing a retrospective telephone consultation about their care at 6–8 weeks postpartum. The questionnaire found high levels of satisfaction, and recorded a National Health Service Friends and Family Test score of 93. In the telephone consultation, 87% of the women reported that they were complying with ongoing PFM training. Eighty-five per cent of women who completed the questionnaire suggested that outpatient physiotherapy follow-up would be useful. Fifty per cent stated that options inclusive of outpatient follow-up would be useful for onward service development. Because of the high levels of satisfaction recorded and high compliance with the information provided in the acute postpartum period, it was concluded that the service should continue as it is. It is hoped that this service evaluation can be utilized as a benchmark for other acute and outpatient pelvic health physiotherapy services.

Are pelvic floor muscle function, quadriceps femorismuscle, gluteus mediusmuscle, hand grip strength and functional performance affected by incontinence types in elderly people with urinary incontinence?

The aim of this study is to examine the relationship between incontinence type and pelvic floor muscle function, gluteus mediusmuscle, quadriceps femorismuscle, hand grip strength, functional performance and balance in elderly people with incontinence. This cross-sectional study was conducted in a nursing home with 78 elderly people with stress (SUI, n: 20), urgency (UUI, n: 27) and mixed (MUI, n: 31) urinary incontinence. "Urogenital Distress Inventory-6, Incontinence Impact Questionnaire Form-7, Overactive Bladder-8" were used to evaluate incontinence symptoms and severity. Superficial electromyography was used to evaluate the function of the PFM. A hand dynamometer was used to evaluate hand grip strength, and a digital manual muscle tester was used to evaluate quadriceps femoris (QF) and gluteus medius muscle strength. Short Physical Performance Battery and Time Up and Go Test were performed for functional performance. There was no significant difference between PFM contraction and relaxation functions, gluteus medius, QF muscle strength, functional performance (p > 0.05) but hand grip strength was highest in the group with UUI (ptotal: 0.022).The group with the highest rate of low hand grip strength is MUI (38.7%). A weak positive correlation was found between QF muscle strength and PFM Work Average value in the MUI group (r: 0.370, p: 0.048). In the MUI group, a moderate positive correlation was found between hand grip strength and gluteus medius muscle strength (r: 0.499, p: 0.005). Our findings show that hand grip strength is related to the type of incontinence in the elderly people. The average hand grip strength was highest in the elderly people with UUI. Additionally, there was a positive relationship between gluteus medius and hang grip strength in MUI. It may provide guidance for evaluation and risk factors in elderly people with incontinence.

Ultrasound Assessment and Self-Perception of Pelvic Floor Muscle Function in Women with Stress Urinary Incontinence in Different Positions

Objectives: This study analyzed the effect of different positions on pelvic floor muscle (PFM) function in women with and without stress urinary incontinence (SUI). Methods: This study included women with (n = 17, research group) and without (n = 25, control group) SUI. Using abdominal ultrasound, PFM function (maximum contraction and endurance) was measured in four different positions: lying, sitting, standing and squatting. The level of difficulty perceived by the participants was recorded. Results: In both groups, the best contraction was observed in the standing position and the weakest in the lying position. Women with SUI showed a lower ability to perform PFM contraction. A significant difference was found between the groups in the sitting and standing positions, and it was smaller in the research group. In the research group, the contraction displacement during sitting was 2.68 (1.67) mm versus 4.51 (2.62) mm in the control. The displacement during standing was 6.92 (3.50) mm versus 9.18 (5.05) mm, respectively (p < 0.05). In the research group, 52.9% reported the sitting position as the most difficult compared with only 12% in the control group. Conclusions: Women with SUI have lower PFM function while standing or sitting, but not while lying, than those without SUI. Variations in PFM function across different positions exist. A new protocol for PFM examination should be written with the standing position included.

Perineal Rehabilitation in Pelvic Floor Dysfunction: The Benefits of Vaginal Cone Training

Pelvic floor dysfunctions (PFD) are prevalent conditions that affect millions of women worldwide, encompassing a range of issues severely affecting women's quality of life. Pelvic floor muscle strength and function are fundamental to the management and prevention of PFD, and pelvic rehabilitation is a non-invasive approach that effectively improves symptoms, restores function, and prevents complications. This study aimed to evaluate the impact of pelvic floor muscle training program using weighted vaginal cones, on pelvic floor muscle function and quality of life in women with pelvic floor dysfunction (PFD). Fifty-four women aged 26-62 years, with different type of urinary incontinence, cystocele, and prolapse participated in this pre-post intervention comparative analysis. Pelvic floor muscle function was assessed using the PC test, which measures strength, endurance and fatigability, while the impact on patients' quality of life was assessed with the Pelvic Floor Impact Questionnaire - Short Form 7 (PFIQ-7). A three-month vaginal cone training regimen was implemented, with as-sessments conducted before the intervention (T0), one month later (T1), and three months later (T2). Data analysis showed a change with significant differences between the PC test score values at the level of each parameter and at each assessment (p<0.05, ES=0.254-511). The scores for bladder and urinary problems Urinary Impact Questionnaire (UIQ-7) significantly de-creased from 38.901 ± 1.268 at T0 to 29.366 ± 2.493 at T2 (W = 1082.000, p < 0.001, ES=0.570). In contrast, the scores for vaginal or pelvic problems (POPIQ-7) showed a slight, insignificant decrease from 12.699 ± 1.128 at T0 to 10.499 ± 2.362 at T2 (W = 278.000, p = 0.800, ES=0.053). fVaginal cone training significantly improves pelvic floor mus-cle function and reduces urynary symptoms in women with PFD.

Effects of pelvic floor muscle training (PFMT) on the sexual function of climacteric women: a systematic review protocol

Introduction Climacteric period signifies a transitional phase characterized by ovarian failure and a decline in estrogen levels, leading to various urogynecological alterations, including potential sexual dysfunctions. Among these, pelvic floor muscle (PFM) function plays a pivotal role in female sexual function. This study aims to evaluate the efficacy of pelvic floor muscle training (PFMT) on the sexual function of climacteric women. Methods Experimental or quasi-experimental studies published in peer-reviewed journals, assessing the sexual function of perimenopausal women with PFMT as an intervention, will be included. Studies conducted in institutionalized populations or with neurological and cognitive diseases will be excluded. This systematic review protocol follows the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). The searches will be carried out in the Pubmed, LILACS (Latin American and Caribbean Literature on Health Sciences), Scopus, Web of Science, and PEDro, using the Search equation: climacteric women/menopause and PFMT and (sexual function or sexual dysfunction). The assessment of methodological quality will be carried out using the Pedro and GRADE scale, which will involve two independent researchers to evaluate the criteria. A third researcher will resolve discrepancies. Ethics and disclosure Ethical approval is not required as this is a secondary data study. This systematic review began in April 2024 and all steps are expected to be completed by November 2024. PROSPERO registration number CRD42024534297

Effects of Inspiratory Muscle Training on Stress Urinary Incontinence in North African Women: A Randomized Controlled Trial.

Pelvic floor muscles (PFMs) are involved in respiratory mechanisms. Additionally, stress urinary incontinence (SUI) can affect physical function. This randomized controlled trial was aimed at investigating the effects of inspiratory muscle training (IMT) on SUI severity, PFM function, and physical function in Tunisian women with SUI. Twenty-seven incontinent women were randomly assigned to either the experimental group or the control group. The following parameters were assessed: respiratory muscle strength (RMS; maximal inspiratory and expiratory pressures), SUI severity (Urogenital Distress Inventory-6; Incontinence Impact Questionnaire-7; pad test), PFM function (Modified Oxford Scale, electromyography, and endurance), and physical function (Timed Up & Go test; 6-min walk test; incremental shuttle walking test). IMT was conducted using threshold IMT. The IMT program significantly reduced the severity of SUI (p < 0.01), improved PFM function (p < 0.001), enhanced physical function (p < 0.01), and increased RMS (p < 0.001). Inspiratory muscle training could be an effective method for improving pelvic floor disorders and physical function in women with SUI.

Association of pre-pregnancy body mass index and gestational weight gain on postpartum pelvic floor muscle morphology and function in Chinese primiparous women: A retrospective cohort study.

Our study aimed to investigate the association between maternal pre-pregnancy body mass index (BMI), gestational weight gain (GWG), and impaired pelvic floor muscle (PFM) morphology and function during the early postpartum period. This retrospective cohort study was conducted at Shanghai First Maternity and Infant Hospital from December 2020 to December 2022. A total of 1118 primiparous women with singleton pregnancies who underwent vaginal deliveries and participated in postpartum PFM assessments were included. Maternal pre-pregnancy BMI and GWG were considered as exposures. PFM morphology and function impairment were the primary outcomes. PFM morphology impairment, defined as levator ani muscle avulsion, was assessed using transperineal ultrasound. PFM function impairment, manifested as diminished PFM fiber strength, was assessed through vaginal manometry. Multivariable logistic regression analysis was employed to calculate adjusted odds ratios (aOR) with 95% confidence intervals (CI). Restricted cubic spline models were used to validate and visualize the relationship. Women with lower pre-pregnancy BMI were at an increased risk of levator ani muscle avulsion (aOR = 1.73, 95% CI: 1.10-2.70, P = 0.017), particularly when combined with excessive GWG during pregnancy (aOR = 3.20, 95% CI: 1.15-8.97, P = 0.027). Lower pre-pregnancy BMI was also identified as an independent predictor of PFM weakness (aOR = 1.53, 95% CI: 1.08-2.16, P = 0.017 for type I fiber injuries). Notably, regardless of the avulsion status, both underweight and overweight/obese women faced an elevated risk of reduced PFM strength (aOR = 1.74, 95% CI: 1.17-2.59, P = 0.006 for underweight women with type I fiber injuries; aOR = 1.67, 95% CI: 1.06-2.64, P = 0.027; and aOR = 1.73, 95% CI: 1.09-2.76, P = 0.021 for overweight/obese women with type I and type II fibers injuries, respectively). Both lower and higher pre-pregnancy BMI, as well as excessive GWG, were strongly associated with PFM impairments. These findings highlighted the critical importance of comprehensive weight management throughout pregnancy to effectively promote women's pelvic health.

Effectiveness of Pelvic Floor Muscle and Education-Based Therapies on Bladder, Bowel, Vaginal, Sexual, Psychological Function, Quality of Life, and Pelvic Floor Muscle Function in Females Treated for Gynecological Cancer: A Systematic Review.

Gynecological malignancies are prevalent in females, and this population is likely to experience symptoms of pelvic floor disorders and sexual dysfunction. Non-surgical, non-pharmaceutical conservative therapies, namely pelvic floor muscle (PFM) therapies and education-based interventions, could be beneficial for this population. The purpose of this systematic review was to examine the evidence regarding their effectiveness on bladder, bowel, vaginal, sexual, psychological function, quality of life, and PFM function in gynecological cancer populations. Six databases were searched to identify studies employing any interventional study design, except case studies, to investigate the effect of PFM therapies, education-based interventions, or combined therapies on any outcome of interest. The search yielded 4467 results, from which 20 studies were included. Of these, 11 (55%) were RCTs, two (10%) were non-RCTs with two groups, and seven (35%) were non-RCTs with a single group. Findings suggest that combined (multimodal) therapies, specifically PFM (active > passive) + education therapies, appear more effective for vaginal, overall pelvic floor, sexual, and PFM function. PFM therapies (active and/or electrostimulation) may improve bladder outcomes. Limited evidence suggests PFM (active) + education therapies may improve bowel function. Conservative therapies may improve psychological function, although available data do not appear to favor a particular therapy. Given the conflicting findings regarding quality of life, no clear conclusions can be made. Interpretation of findings highlighted the importance of intervention dosage, adherence, and supervision for optimal effectiveness. Despite the limitations of the included studies, this review provides new and valuable insights for future research and clinical practice.

Brazilian Portuguese Translation and Validation of the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-IUGA revised.

Condition-specific sexual questionnaires are important patient-reported outcome measures. The aim of this study was to translate and validate the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-International Urogynecology Association Revised (PISQ-IR) into Brazilian Portuguese and to clinically validate it in a Brazilian Portuguese-speaking population. Translation and validation of the PISQ-IR was performed according to the International Urogynecological Association-recommended process and guidelines. For external validity, PISQ-IR subscales were compared with the clinical measures, Pelvic Organ Prolapse Quantification system (POP-Q) stage, pelvic floor muscle tone, and Oxford Grading Scale (Pearson correlations). Descriptive statistics, internal consistency (Cronbach's alpha coefficient), and test-retest reliability (interclass correlation coefficient) were calculated for all PISQ-IR subscales. A total of 120 sexually active and 106 not sexually active women were enrolled in the study between March 2015 and July 2019. Internal consistency was acceptable, with Cronbach's alpha values 0.60-0.80, except for the sexual arousal and orgasm, sexual arousal and partner-related issues, sexual arousal and condition-specific issues, global rating of sexual quality and condition impact subscales. PISQ-IR demonstrated good reliability (α > 0.6, CIC = 0.996). The agreement for each individual questionnaire item also individually presented substantial agreement between the assessments (κ 0.61-0.8). There was a correlation between PISQ-IR and POP, mixed, stress and fecal incontinence diagnosis and a positive correlation with pelvic floor muscle function according to the Oxford Scale in sexually active women. For sexually inactive women there was a correlation between PISQ-IR and mixed urinary symptoms. The Brazilian Portuguese version of PISQ-IR is a reliable and valid tool that can be easily used for the identification and assessment of sexual function in Brazilian Portuguese-speaking women with pelvic floor disorders.

Acute Effect of Transcranial Direct Current Stimulation in Pelvic Floor Muscle Function in Young Healthy Women: Initial Findings of a Randomized Controlled Trial.

Transcranial direct current stimulation (tDCS) can enhance muscle function in healthy individuals. However, it is unknown if tDCS associated with pelvic floor muscle training (PFMT) can improve pelvic floor muscle function (PFMF) in healthy women. The aim of this study was to investigate the acute effect of a single session of tDCS in PFMF compared with sham-tDCS in healthy women. A double-blind, cross-over, randomized clinical trial was conducted with healthy, nulliparous and sexually active women. PFMF was assessed by bidigital palpation (PERFECT scale) and intravaginal pressure by a manometer (Peritron™). Participants randomly underwent two tDCS sessions (active and sham) 7 days apart. The electrode was positioned equal for both protocols, the anode electrode in the supplementary motor area (M1) and the cathode electrode in the right supraorbital frontal cortex (Fp2). The current was applied for 20min at 2mA in active stimulation and for 30s in sham-tDCS. The tDCS applications were associated with verbal instructions to PFMT in a seated position. After each tDCS session PFMF was reevaluated. Twenty young healthy women (aged 23.4 ± 1.7years; body mass index 21.7 ± 2.2kg/m2) were included. No difference was observed in power, endurance, and intravaginal pressure of PFMF (p > 0.05). The number of sustained contractions improved from 3.0 (2.0-3.5) to 4.0 (3.0-5.0) after active-tDCS (p = 0.0004) and was superior to sham-tDCS (p = 0.01). The number of sustained contractions of PFM improved immediately after a single active-tDCS session, with a difference compared with the post-intervention result of sham-tDCS in healthy young women.

Biofeedback combined with percutaneous electrical pudendal nerve stimulation for the treatment of low anterior rectal resection syndrome: a study protocol for a randomized controlled trial

BackgroundLow anterior resection syndrome (LARS) is a distressing condition that affects approximately 25–80% of patients following surgery for rectal cancer. LARS is characterized by debilitating bowel dysfunction symptoms, including fecal incontinence, urgent bowel movements, and increased frequency of bowel movements. Although biofeedback therapy has demonstrated effectiveness in improving postoperative rectal control, the research results have not fulfilled expectations. Recent research has highlighted that stimulating the pudendal perineal nerves has a superior impact on enhancing pelvic floor muscle function than biofeedback alone. Hence, this study aims to evaluate the efficacy of a combined approach integrating biofeedback with percutaneous electrical pudendal nerve stimulation (B-PEPNS) in patients with LARS through a randomized controlled trial (RCT).Methods and analysisIn this two-armed multicenter RCT, 242 participants with LARS after rectal surgery will be randomly assigned to undergo B-PEPNS (intervention group) or biofeedback (control group). Over 4 weeks, each participant will undergo 20 treatment sessions. The primary outcome will be the LARS score. The secondary outcomes will be anorectal manometry and pelvic floor muscle electromyography findings and the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire-Colorectal 29 (EORTC QLQ-CR29) scores. Data will be collected at baseline, post-intervention (1 month), and follow-up (6 months).DiscussionWe anticipate that this study will contribute further evidence regarding the efficacy of B-PEPNS in alleviating LARS symptoms and enhancing the quality of life for patients following rectal cancer surgery.Trial registrationChinese Clincal Trials Register ChiCTR2300078101.

Prevalence, Bother, and Risk Factors Associated With Occurrence of Pelvic Floor Dysfunctions in Young Women: A Cross-Sectional Survey

Purpose: Pelvic floor dysfunctions (PFD) have been increasingly reported in young female athletes, but it is likely that young women, not specific to athletes, might also experience symptoms of PFD. This study investigated the occurrence of PFD symptoms in young women from the general population, their degree of bother and functional and clinical factors associated with these occurrences. Methods: Online survey was conducted with young women from the general population, not specific to athletes. Sociodemographic and clinical data, symptoms of urinary (UI) and anal incontinence (AI), pelvic organ prolapse, dyspareunia, chronic pelvic pain, and functional constipation, as well as their degree of bother were collected using validated questionnaires. Fisher exact and χ2 tests, Student t tests, and logistic regression models were applied (α = .05). Results: A total of 337 women aged 18 to 25 years were investigated. The overall occurrence of PFD was 60.0%. Dyspareunia was the most prevalent symptom (49.2%), followed by UI (44.2%) and constipation (21.7%). Higher degree of bother was reported for UI, AI, and chronic pelvic pain, respectively. Constipation (P &lt; .001) and anxiety (P = .004) were associated with occurrence of PFD, increasing the chances of PFD by 4 and 2 times, respectively. Discussion: The high occurrence, co-occurrence, and bother of PFD in young women suggest impairments in pelvic floor muscle functions that should be investigated by physical therapists. Educational programs including preventive strategies and the role of physical therapists in the treatment of PFD should be provided from early ages.

Sexual function in women with endometriosis and pelvic floor myofascial pain syndrome.

To evaluate and compare the sexual function and pelvic floor muscles (PFM) function of women with endometriosis and chronic pelvic pain (CPP) with and without Myofascial Pelvic Pain Syndrome (MPPS). Cross-sectional study conducted between January 2018 and December 2020. Women with deep endometriosis underwent assessments for trigger points (TP) and PFM function using the PERFECT scale. Electromyographic activity (EMG) and sexual function through Female Sexual Function Index (FSFI) were assessed. Statistical analyses included chi-square and Mann-Whitney tests. There were 46 women. 47% had increased muscle tone and 67% related TP in levator ani muscle (LAM). Weakness in PFM, with P≤2 was noted in 82% and P≥3 in only 17%. Incomplete relaxation of PFM presented in 30%. EMG results were resting 6.0, maximal voluntary isometric contraction (MVIC) 61.9 and Endurance 14.2; FSFI mean total score 24.7. We observed an association between increased muscle tone (P<.001), difficulty in relaxation (P=.019), and lower Endurance on EMG (P=.04) in women with TP in LAM. Participants with TP presented lower total FSFI score (P=.02). TP in the right OIM presented increased muscle tone (P=.01). TP in the left OIM presented lower values to function of PFM by PERFECT (P=.005), and in MVIC (P=.03) on EMG. Trigger points (TP) in pelvic floor muscles (PFM) and obturator internus muscle (OIM) correlates with poorer PFM and sexual function, particularly in left OIM TP cases. Endometriosis and chronic pelvic pain raise muscle tone, weaken muscles, hinder relaxation, elevate resting electrical activity, lower maximum voluntary isometric contraction, and reduce PFM endurance.

The Comparison of Individual and Group Hybrid Telerehabilitation Methods in Women with Urinary Incontinence.

The aim is to compare the effects of the progressive training program (PTP), a new protocol, with two different hybrid telerehabilitation methods, on the parameters related to urinary incontinence in women with urinary incontinence. A total of 50 participants with stress or mixed urinary incontinence participated in this two-arm, parallel-group, randomized, non-inferiority trial. Individual hybrid training (IHT) or group hybrid training (GHT) was given to women for 8weeks. The Power, Endurance, Repetitions, Fast contractions, and Every Contraction Timed (PERFECT) scheme and surface electromyography were used to assess pelvic floor muscle function, whereas quality of life, exercise adherence, and symptoms were assessed by questionnaires and a 3-day bladder diary. An intention-to-treat analysis was performed. Linear mixed model analysis with the factors "time" and "group" was used to determine the effects of IHT and GHT. The primary outcome was changes in pelvic floor muscle function as evaluated using the PERFECT scheme and surface electromyography at the 4th and 8th weeks relative to baseline. No statistical difference was found between the groups except for "power" of the PERFECT scheme and "nocturnal urination frequency" (p > 0.05). The GHT showed significant improvement in P and nocturnal urination frequency at the end of the 8th week (p < 0.05). From baseline to week 8, the effect size for the P value was found to be small (Cohen's d = 0.33). Eightweeks of PTP did not lead to different results in incontinence-related parameters in either of the training methods. It may be better to conduct GHT in terms of implementing PTP in incontinence and training programs in terms of time, staff workload, and applicability.

Impact of pelvic floor muscle training on sexual function in women affected by stress urinary incontinence.

Pelvic floor muscle training can effectively improve pelvic floor muscle strength and activities; however, its impact on sexual function in women with stress urinary incontinence remains unclear. The study sought to investigate the impact of pelvic floor muscle training on pelvic floor muscle and sexual function in women with stress urinary incontinence. This was a retrospective observational study involving women who visited a urogynecologic clinic at a tertiary medical center. Patients with stress urinary incontinence without pelvic organ prolapse underwent pelvic floor muscle training programs that included biofeedback and intravaginal electrostimulation. Other evaluations included pelvic floor manometry, electromyography, and quality-of-life questionnaires, including the short forms of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, Urogenital Distress Inventory, and Incontinence Impact Questionnaire. Clinical characteristics, vaginal squeezing and resting pressure, maximal pelvic floor contraction, duration of sustained contraction, quality-of-life scores, and sexual function were compared between baseline and after the pelvic floor muscle training programs. There were 61 women included in the study. The mean number of treatment sessions was 12.9 ± 6.3, and the mean treatment duration was 66.7 ± 32.1days. The short forms of the Urogenital Distress Inventory (7.7 ± 3.8 vs 1.8 ± 2.1; P < .001) and Incontinence Impact Questionnaire (5.9 ± 4.3 vs 1.8 ± 2.0; P < .001) scores significantly improved after the pelvic floor muscle training program. In addition, all pelvic floor muscle activities significantly improved, including maximal vaginal squeezing pressure (58.7 ± 20.1 cmH2O vs 66.0 ± 24.7 cmH2O; P = .022), difference in vaginal resting and maximal squeezing pressure (25.3 ± 14.6 cmH2O vs 35.5 ± 16.0 cmH2O; P < .001), maximal pelvic muscle voluntary contraction (24.9 ± 13.8 μV vs 44.5 ± 18.9 μV; P < .001), and duration of contraction (6.2 ± 5.7 s vs 24.9 ± 14.6s; P < .001). Nevertheless, the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire score demonstrated no significant improvement (28.8 ± 9.7 vs 29.2 ± 12.3; P = .752). Pelvic floor muscle training programs may not improve sexual function in women with stress urinary incontinence. The strength of this study is that we evaluated sexual function with validated questionnaires. The small sample size and lack of long-term data are the major limitations. Pelvic floor muscle training can improve pelvic floor muscle activities and effectively treat stress urinary incontinence; however, it may not improve sexual function.
