Pelvic Floor Muscle Parameters Affect Sexual Function After 8 Weeks of Transcutaneous Electrical Stimulation in Women with Stress Urinary Incontinence

Association between overactive bladder and female sexual frequency: a cross-sectional analysis of the National Health and nutrition examination survey data

BACKGROUND

Overactive bladder (OAB) and female sexual dysfunction (FSD) are both common problems in women, but the association between OAB and FSD lacks a large sample study. The purpose of this cross-sectional study was to investigate the association between OAB and FSD.

METHODS

Data for this study were obtained from the 2007-2016 National Health and Nutrition Examination Survey (NHANES) for women aged 20-59 years. OAB was qualified with the aid of the overactive bladder symptom score (OABSS), which was obtained by adding the nocturia score and the urge urinary incontinence score, and participants with a total score ≥ 3 were considered to suffer from OAB. The FSD was defined as a sexual frequency of less than 12 times per year. After adjusting for covariates including basic demographic information, social information (e.g., marital status), gynecological (e.g., abnormal menstruation), and significant medical comorbidities, the association between OAB and FSD was assessed using survey-weighted logistic regression mode. In addition, subgroup analysis and sensitivity analysis were used to further assess the reliability of the findings.

RESULTS

A total of 5590 women aged 20-59 were eligible in the final analysis from 2007 to 2016 NHANES. 30.43% of participants (n = 1701) were identified as FSD reporting sexual frequency of 0-11 times/year, while 69.57% of participants (n = 3889) were identified as normal female sexual function reporting sexual frequency > 11 times/year. We performed logistic regression analysis to examine the association between OAB and FSD. The results demonstrated that participants with OAB (OABSS < 3) were 23% more likely to report lower sexual frequency (≤ 11) than those without OAB (OABSS ≥ 3) after adjusting fully for demographics, social history, gynecologic history and significant medical conditions (OR: 1.23, 95%CI: 1.01-1.49, P = 0.040).

CONCLUSION

The study demonstrated the positive association between OAB and FSD measured by low sexual frequency among women 20-59 years old in the U.S. population; it is necessary to perform more comprehensive cohort studies to gain more profound understanding of the association between them.

Pelvic Floor Muscle Training vs. Vaginal Vibration Cone Therapy for Postpartum Dyspareunia and Vaginal Laxity

Background and Objectives: Pelvic floor dysfunction and sexual health issues are common postpartum due to weakened pelvic muscles, significantly impacting women's quality of life (QoL). Pelvic floor muscle training (PFMT) is a widely used approach to address these issues. This study aimed to compare the effectiveness of two rehabilitation methods-vibrating vaginal cones (VCG) and PFMT exercises (CG)-in improving pelvic floor muscle strength, reducing dyspareunia, and enhancing sexual function in postpartum women. Materials and Methods: This 1-year retrospective observational analysis evaluated 57 postpartum women presenting with perineal muscle relaxation and sexual dysfunction. Participants were assessed 3 months postpartum (T0) and after 3 months of therapy (T1) at the Pelvic Floor Rehabilitation Clinic of Santa Chiara Hospital, Pisa. Outcomes were measured using the pubococcygeus (PC) test for pelvic floor strength and the Female Sexual Function Index (FSFI) for sexual function. Results: The results revealed significant improvements in pelvic floor muscle strength and sexual function across both groups. While both interventions effectively reduced dyspareunia, the VCG group demonstrated superior outcomes, with 96.67% of participants reporting no pain compared to 80.95% in the CG. FSFI scores improved significantly in both groups, with greater enhancements in arousal, desire, and pain domains observed in the VCG group (p < 0.01). Vaginal cone therapy also resulted in slightly higher gains in overall pelvic floor strength. Conclusions: These findings suggest that vibrating vaginal cones may be a promising option for postpartum pelvic floor rehabilitation, with potential benefits for improving sexual satisfaction and reducing pain.

Supervised Pelvic Floor Muscle Training Improves Sexual Function and Diminishes Sexual Distress in Women with Relapsing-Remitting Multiple Sclerosis: A Randomised Controlled Study

This study investigates the impact of pelvic floor muscle training (PFMT) on sexual function and distress in women with multiple sclerosis (MS), a prevalent chronic nervous system disorder associated with sexual dysfunction. This study's primary aim was to assess the effectiveness of PFMT at improving sexual function and alleviating sexual distress in this population. In a randomised controlled trial, 82 women with MS were divided into two groups: Group A (41 women) underwent 12 weeks of PFMT, while Group B (41 women) served as a control group with no intervention. Both groups were assessed at the beginning and end of this study using the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R). Statistical analysis, including Chi-square tests, was employed to compare the outcomes between the two groups, with a p-value of less than 0.05 considered significant. The results revealed no significant differences in baseline sexual function and distress between the groups. However, at the conclusion of the 12-week period, Group A exhibited statistically significant improvements in nearly all domains of FSFI and FSDS-R compared to Group B, except in the pain domain. This study concludes that PFMT can effectively enhance sexual function and reduce sexual distress in women suffering from MS. These findings underscore the potential of PFMT as a therapeutic intervention in managing sexual dysfunction associated with MS.

Effect of pelvic floor muscle electrical stimulation on lumbopelvic control in women with stress urinary incontinence: randomized controlled trial

INTRODUCTION

The pelvic floor muscle (PFM) plays a role not only in lumbopelvic stabilization, but also in incontinence and sexual function.

OBJECTIVE

This study aimed to determine the effectiveness of PFM training by electrical stimulation (ES) on urinary incontinence, PFM performance (i.e. strength and power), lumbopelvic control, and abdominal muscle thickness in women with stress urinary incontinence (SUI).

METHODS

Participants were randomized into ES and control groups. The ES group underwent PFM ES for 8 weeks, whereas the control group underwent only a walking program. The impact of urinary incontinence on quality of life was assessed by the Incontinence Impact Questionnaire (IIQ)-7. PFM strength and power were measured using a perineometer. Lumbopelvic control was measured by one and double-leg-lowering tests. Abdominal muscle thickness was measured by sonography.

RESULTS

The ES group showed significantly improved IIQ-7 scores and PFM performance, and had significantly higher values in both one and double-leg lowering tests (p < .05) after 8 weeks of training, indicating significant improvement from pre-session values (p < .005). There were no significant between- or within-group differences at rest in abdominal muscle thickness.

CONCLUSION

PFM ES could improve lumbopelvic control and PFM performance, and reduce subjective symptoms of urinary incontinence in women with SUI.

Perspectives on the Therapeutic Effects of Pelvic Floor Electrical Stimulation: A Systematic Review

Pelvic, perineal, and nervous lesions, which derive principally from pregnancy and childbirth, may lead to pelvic floor dysfunctions, such as organ prolapses and lesions in the nerves and muscles due to muscle expansion and physiology. It is estimated that 70% of women affected by this clinical picture have symptoms that do not respond to the classical treatments with antimuscarinic and anticholinergic drugs. Therefore, resorting to efficient alternatives and less invasive methods is necessary to assist this public health problem that predominantly affects the female population, which is more susceptible to the risk factors. This study aimed to perform an updated and comprehensive literature review focused on the effects of pelvic floor electrical stimulation, considering new perspectives such as a correlation between electric current and site of intervention and other molecular aspects, different from the present reviews that predominantly evaluate urodynamic aspects. For that purpose, PubMed and ScienceDirect databases were used to perform the search, and the Methodi ordinatio method was applied. With well-researched therapeutic effects, electrical stimulation induced promising results in histological, nervous, and molecular evaluations and spinal processes, which showed beneficial results and revealed new perspectives on ways to evoke responses in the lower urinary tract in a non-invasive way. Thus, it is possible to conclude that this type of intervention may be a non-invasive alternative to treat pelvic and perineal dysfunctions.

Long-Term Effect of Early Post-operative Transcutaneous Electrical Stimulation on Voiding Function After Radical Hysterectomy: A Multicenter, Randomized, Controlled Trial

Introduction: Post-radical-hysterectomy (RH) patients suffer from a series of problems resulting from neurovascular injury, such as bladder dysfunction, which reduce their quality of life. We have designed this study to evaluate the efficacy of transcutaneous electrical stimulation (TENS) on patient rehabilitation after RH for early cervical cancer.

Materials and methods: A total of 97 patients were enrolled in a randomized-controlled trial (from January 2015 to December 2019) involving 7 medical centers nationwide. Patients were assigned to either the intervention group (n = 46), or the control group (n = 51). TENS was given to patients in the intervention group from the 7^th day after surgery for a total of 14–21 days. The control group received no TENS. Primary outcomes were measured for residual urine volume and recovery of urination function. Secondary outcomes were measures for urodynamics (UDS), pelvic floor electromyography function examination (PFEmF), and quality of life (QoL).

Results: Residual urine volume and improvement in the rate of urination were found to show no significant differences on the 14^th, 21^st, and 28^th days after surgery. The maximum flow rate (Qmax) in the intervention group was significantly higher than that in the control group on the 28^th day, but there were no significant differences in average flow rate, voiding time, time to Qmax, muscle fiber strength, muscle fiber fatigue, and the abnormal rate of A3 reflection on the 28^th day and the 3^rd mo., as well as in the QoL at 3^rd mo., 6^th mo., and 12^th mo. after surgery.

Conclusion: Our study showed no sufficient evidence to prove that TENS under the trialed parameters could improve the subject's voiding function, PFEmF, and QOL after RH. This has provided valuable data for rehabilitation after RH.

Effect of pelvic floor electrical stimulation on diaphragm excursion and rib cage movement during tidal and forceful breathing and coughing in women with stress urinary incontinence: A randomized controlled trial

BACKGROUND

The pelvic floor muscle (PFM) is associated with respiratory function. We investigated the effects of PFM training by pelvic floor electrical stimulation (PFES) on PFM strength, diaphragm excursion, and upper rib cage movement during tidal and forceful breathing and coughing in women with stress urinary incontinence (SUI).

METHODS

In total, 33 participants with SUI were divided into PFES and control groups. The two groups were measured pre- and post-8 weeks of training. Diaphragm excursion and upper rib cage movement during tidal and forceful breathing and coughing and PFM strength were measured using sonography, electromagnetic sensors, and perineometry.

RESULTS

There were significant difference of main effect between pre- and post-training and between groups in PFM strength (between groups: P = .001, between time: P < .001) and diaphragm excursion during forceful breathing (between groups: P = .015, between time: P = .026) and coughing (between groups: P = .035, between time: P = .006). There were significant differences in diaphragm excursion during tidal (P = .002) and forceful breathing (P = .005) and coughing (P < .001) between pre- and post-training in the PFES group. Elevation of the upper rib cage during tidal (P < .001) and forceful breathing (P = .001) was significantly decreased after 8 weeks of training in the PFES group. Widening in the horizontal plane in the upper rib cage during forceful breathing (P < .001) was significantly increased after 8 weeks of training in the PFES group. PFM strength (P < .001) was significantly increased after 8 weeks of training in the PFES group.

CONCLUSIONS

Pelvic floor muscles training by electrical stimulation can improve diaphragm excursion and breathing patterns in women with SUI.

Biofeedback versus electrical stimulation for sexual dysfunction: a randomized clinical trial

INTRODUCTION AND HYPOTHESIS

Sexual dysfunction is a common problem in the general population. We compared the effects of biofeedback and electrical stimulation on the symptoms of sexual pain dysfunction in women with urinary stress incontinence.

METHODS

We carried out a parallel randomized clinical trial in an outpatient department for physical medicine and rehabilitation at a university hospital. Based on DSM-5 criteria for sexual dysfunction, 22 patients with sexual dysfunction and stress incontinence were included and randomly allocated to each study arm. The primary outcome measure was the total score on the Female Sexual Function Index. Each group underwent pertinent treatment for 100 min, two times a week for 6 weeks.

RESULTS

Both groups showed favorable outcomes in increasing Female Sexual Function Index mean scores and their domains. However, for improving sexual function, women in the biofeedback group benefited more than those receiving electrical stimulation. Biofeedback raised desire, arousal, lubrication, orgasm, and satisfaction scores more than electrical stimulation (all p ≤ 0.025). Both interventions decreased pain during or following vaginal penetration similarly (p = 0.985).

CONCLUSIONS

Both biofeedback and electrical stimulation increased the Female Sexual Function Index score. However, to improve sexual function, women undergoing biofeedback seem to benefit more than those receiving electrical stimulation. We recommend considering the prescription of biofeedback for the treatment of sexual dysfunction because of its efficacy, lack of adverse effects, and easy application.
