Long-Term Efficacy of Physical Therapy for Localized Provoked Vulvodynia

Physical Modalities for the Treatment of Localized Provoked Vulvodynia: A Scoping Review of the Literature from 2010 to 2023

Introduction

Localized provoked vulvodynia (LPV) is a prevalent sexual health condition with significant negative impacts on quality of life. There is a lack of consensus regarding effective management.

Methods

We used Arksey and O'Malley's five-step method to identify, collate, and evaluate literature published between 2010 and 2023. The scoping review investigated the efficacy or effectiveness of interventions in the management of LPV. The aim of this paper is to map the literature on the efficacy or effectiveness of physical interventions.

Results

The review produced 19 primary studies of physical interventions for LPV. These include acupuncture, laser therapy, physiotherapy, transcutaneous electrical nerve stimulation, low-intensity shockwave therapy, transcranial direct current stimulation, and vestibulectomy.

Conclusion

Published studies that investigated a range of physical treatments for LPV showed some positive effects, except for transcranial direct-current stimulation. The remaining modalities demonstrated improved sexual pain and treatment satisfaction, when measured. Findings were mixed for non-sexual pain. There was insufficient evidence to draw conclusions regarding other outcomes. Researchers are encouraged to conduct larger, high-quality studies that sample more diverse patient populations and use patient-oriented outcomes to assess effectiveness of physical modalities.

Individualized multidisciplinary therapy for vulvodynia

OBJECTIVE

The main objective of this review was to develop strategies for individualizing multidisciplinary therapy for vulvodynia.

METHODS

We conducted two literature searches; the first one focused on clinical trials assessing vulvodynia treatments published after the recommendations of the expert committee of the Fourth International Consultation on Sexual Medicine. The second search targeted studies identifying predictive factors and mediators of vulvodynia treatments, published from the earliest date to October 2022.

RESULTS

Based on data from 55 relevant studies, we developed models of individualized multidisciplinary therapy targeting groups of women less responsive to multidisciplinary therapy (characterized by women with higher vulvar pain intensity, impaired sexual functioning, and vulvodynia secondary subtype) and to physical therapy, as an isolated treatment (characterized by women with increased pelvic floor muscle tone and vulvodynia primary subtype). Each individualized multidisciplinary therapy model comprises three components: psychotherapy, medical care, and physical therapy. These components provide distinct therapeutic modalities for distinct subgroups of women with vulvodynia; the women subgroups were identified according to the characteristics of women, the disease, partners, and relationships. Additionally, for women with provoked vestibulodynia who exhibit less benefits from vestibulectomy (such as those with higher levels of erotophobia, greater vulvar pain intensity, and the primary subtype) and encounter resistance to individualized multidisciplinary therapy, we suggest additional conservative treatments before performing vestibulectomy.

CONCLUSION

Our study is a pioneer in the development of models that allow the individualization of multidisciplinary therapy for vulvodynia and represents a significant advance in the clinical practice of gynecologists, physiotherapists, and psychologists.

Hypoxia as a potential cause of dyspareunia

Dyspareunia is genital pain before, during or after penile-vaginal sexual intercourse. The prevalence of dyspareunia ranges from 8 to 22%. Sexual intercourse concomitant with a pelvic organic lesion is likely to cause pain in most cases. However, in these cases, the pain depends not only on sexual intercourse. In its basic definition, dyspareunia in women is considered an idiopathic affection without a typical organic constitution. It is only present with penile-vaginal penetration. Long-term hypoxia in perineal muscles can cause muscle and perimuscular changes, leading to chronic pain not sufficiently responding to standard therapy. During the entrance examination to our previous study on dyspareunia, we noted significantly lower pulse oximetry levels in the perineal area of affected women. We aimed to compare pulse oximetry oxygen saturation (SpO2) of dyspareunia-affected women to healthy, pain-free women. A retrospective study was performed. The study participants were women who had participated in our previously published study on dyspareunia. This retrospective study was approved by the Ethical Committee. The study included 62 women: 31 dyspareunia-affected women in the treatment group and 31 healthy women in the control group.

METHOD

During their examinations, women in the dyspareunia and control groups were measured for SpO2. The procedure was performed in the vulvo-perineal rear region, involving the commissure and the bulbospongiosus muscle. Median and mean SpO2 were compared between the treatment and control groups. Testing for sample size accuracy was performed retroactively.

RESULTS

There were 31 participants in each group. The SpO2 data were skewed and did not follow a Gaussian distribution. The Mann-Whitney U test was run to determine differences in perineum oximetry between the treatment group and controls. The median SpO2 was 91 in the treatment group and 92 in the control group. This difference was statistically significant, p = 0.002. Sample size accuracy was assured by post hoc calculation.

CONCLUSIONS

Idiopathic dyspareunia is inherent in cohabitation muscle pain that standard therapy could not explain nor treat. We detected clinically meaningfully decreased levels of SpO2 in affected patients. We compared pelvic oximetry between dyspareunia-affected women in the treatment and control groups. This comparison showed significant hypoxia in the perineal muscle area (p = 0.002). Our results may help us understand the source of this pain and guide treatment accordingly.

Behavioral sex therapy and medications associated in the treatment of provoked vulvodynia: efficacy on pain and sexuality in three illustrative cases

This paper tests the hypothesis that medications combined with behavioral sex therapy might lessen pain and restore sexuality in women with provoked vulvodynia. Three women affected by vulvodynia, otherwise healthy, in heterosexual relationship were treated at the Department of Obstetrics and Gynecology in a university hospital. In consecutive sessions of behavioral sex therapy, oral tricyclic antidepressants and vulvar applications of estrogen and hydrocortisone creams were prescribed in association with vaginal dilators and sensate focus exercises. The outcome supports the hypothesis that combined medications and sexual behavior interventions may be effective in lessening pain and restoring sexuality in women with provoked vulvodynia. The different dyadic balances observed in this small case series suggest how to best use this protocol. The positive results appear to be mostly due to behavioral sex therapy that was the new element added to the combination of pharmacological agents commonly used to treat provoked vulvodynia.
