The Treatment of Provoked Vestibulodynia: A Critical Review

The medicalization of women's sexual pain

The medicalization of women's sexual problems under the overall rubric of female sexual dysfunction (FSD) has been thoroughly critiqued by feminist scholars, health practitioners, and sex therapists. However, there has been much less commentary on the medicalization of women's sexual pain-currently, a subset of an official FSD diagnosis. This article critically examines interdisciplinary understandings and ways of addressing sexual pain. It analyzes these frameworks in relation to feminist theories on medicalization, heteronormativity, and the reciprocal relationship between these two processes. We argue that many women who experience sexual pain have been eager for medicalization as a path to minimizing pain during sexual activity and reinstating normative heterosexual practices and identities. These goals have been lobbied for by patient advocacy groups and noted by professionals in the field. Although there are some clear benefits to this case for medicalization, there are also theoretical, personal, and political costs. Guided by a growing body of feminist theoretical and qualitative, empirical research on this topic, as well as the first author's personal experience of sexual pain, this article highlights some alternatives to medicalization and makes suggestions for change.

Challenging atrophied perspectives on postmenopausal dyspareunia: a systematic description and synthesis of clinical pain characteristics

This study investigated the clinical attributes of postmenopausal dyspareunia. The authors obtained a systematic description of pain symptomatology from 182 postmenopausal dyspareunia sufferers using a structured interview, quantitative sensory testing, a standardized pain measure, and gynecological examination. The authors conducted a cluster analysis to examine whether sufferers could be categorized using clinical pain and gynecological factors. The authors delineated 6 subgroups, each exhibiting distinct combinations of pain and gynecological characteristics. The results support the hypothesis that, similarly to premenopausal dyspareunia, postmenopausal dyspareunia is a heterogeneous condition.

Attributions about pain as predictors of psychological symptomatology, sexual function, and dyadic adjustment in women with vestibulodynia

The present study examined whether attributions for vulvo-vaginal pain predicted pain intensity, sexual function, as well as psychological and dyadic adjustment in women with vestibulodynia. Women with vestibulodynia (N = 77) completed measures of attributions, pain, psychological distress, sexual functioning, and dyadic adjustment. They also took part in a structured interview and a gynaecological examination for diagnostic purposes. Attributions are represented by: (1) internality (personal responsibility) or externality (cause lies in an external situation); (2) globality (entire life affected by the problem) or specificity (problem affecting only a specific situation); (3) stability (problem will still remain in the future) or instability (weak probability that the problem will be maintained with time); and (4) partner responsibility (partner responsible or not for the problem). Results indicated that attributions were not significantly correlated with pain outcomes. However, after controlling for pain intensity and relationship duration, internal attributions predicted higher dyadic adjustment, both global and stable attributions predicted lower dyadic adjustment and higher psychological distress, whereas global attributions also predicted increased sexual impairment. Findings suggest that cognitive factors, such as attributions, may be related to psychological distress, sexual functioning, and dyadic adjustment in women with vestibulodynia. Results also highlight the importance of adhering to a biopsychosocial perspective focusing on pain reduction, sexual rehabilitation, and relationship enhancement in the treatment of dyspareunia.

Early dyspareunia experience in young women: confusion, consequences, and help-seeking barriers

INTRODUCTION

Recurrent painful intercourse or dyspareunia is a highly prevalent health problem associated with impairments in sexual function and psychosocial well-being. Despite its particularly high prevalence in young women, little is known about how young women experience the onset of dyspareunia and how they attempt to manage or address the problem.

AIMS

To explore the subjective experience of early dyspareunia symptoms in young women so as to model its cognitive, emotional, behavioral, and help-seeking trajectory.

METHODS

Using a qualitative methodology broadly based on grounded theory, 14 young women reporting recurrent entry and/or deep pain with intercourse underwent in-depth semistructured interviews asking them to describe their personal experience with dyspareunia symptoms.

MAIN OUTCOME MEASURES

The Female Sexual Function Index was used to screen women with symptoms of dyspareunia. The main outcome measure was a semistructured interview inquiring about the cognitions and emotions associated with the experience of pain with intercourse, causal attributions for the pain, interference with personal, relational, and sexual well-being, and help-seeking decisions.

RESULTS

The model/theory that emerged suggested a sequence of experiences that began with confusion about the onset of pain and a relatively fruitless search for causal attributions. Attempts to self-manage the pain via a number of cognitive and behavioral strategies provided little relief. Deleterious consequences on sexual function, well-being, and relationships ensued, and women reported a number of barriers to help-seeking.

CONCLUSION

The findings from this study suggest that a lack of public health information about dyspareunia and the reluctance of health care providers to inquire about sexual problems may contribute to many young women delaying treatment for a serious sexual health problem with potentially negative biopsychosocial outcomes.

[Vulvodynia and chronic pelvic and perineal pain]

OBJECTIVE

To define vulvodynia and to describe the main approaches to treatment.

MATERIAL AND METHODS

Review of the literature concerning vulvodynia.

RESULTS

Vulvodynia is defined as chronic vulvar discomfort, usually with a burning nature, with no relevant clinical lesions and no clinically identifiable neurological lesion. Localized provoked vulvodynia essentially affects young women and is responsible for major sexual and psychological repercussions. Treatment consists of local anaesthetics, drugs used to treat neuropathic pain, physiotherapy and psychotherapy. Vestibulectomy is only very rarely indicated.

CONCLUSION

Many unknowns persist especially concerning the aetiology of vulvodynia. Evaluation of symptoms and treatment have not been clearly defined. However, symptomatic management provide satisfactory long-term results.

Cognitive behavioral therapy for sexual dysfunctions in women

Sexual dysfunctions in women are classified into disorders of desire, arousal, orgasm, and pain (including dyspareunia and vaginismus). As the cognitive behavioral treatment (CBT) procedures differ among these sexual disorders, the treatments for each disorder are reviewed separately. The efficacy of CBT differs depending on the specific sexual dysfunction to be treated. It is concluded that only a few CBT treatments for women's sexual dysfunction have yet been empirically investigated in a methodologically sound way and little is known about which of the treatment components are most effective.

Impact of educational seminars on women with provoked vestibulodynia

OBJECTIVE

Provoked vestibulodynia (PVD) is a common genital pain condition characterized by severe pain upon vaginal penetration. The treatment of women with PVD suggests variable efficacy across modalities. The emotional toll of PVD, because of the intimate and interpersonal nature of this sexually-provoked pain, and the relationship between PVD and anxiety, depression, and a host of subclinical emotional symptoms that may interfere with treatment, has been well documented. The role of the gynaecologist in identifying and managing these psychological symptoms has never been addressed. The goal of this study was to examine the efficacy of a brief, gynaecologist-led educational seminar on measures of psychological symptoms and sexual health.

METHODS

Twenty-nine women with PVD participated in three one-hour educational seminars led by a gynaecologist with expertise in the management of PVD. Participants completed questionnaires before, immediately after, and six months after the third session.

RESULTS

There were significant improvements in psychological symptoms of depression, anxiety, somatization, hostility, paranoid ideation, psychoticism, and the global severity index, both immediately post-seminar and at the six-month follow-up. Sexual arousal, orgasm, overall sexual function, and sexual distress also significantly improved in response to the seminars.

CONCLUSION

Gynaecologist-led educational seminars delivered in a group format have a significant positive impact on psychological symptoms and sexual functioning in women who suffer from PVD.

Pelvic floor muscle assessment outcomes in women with and without provoked vestibulodynia and the impact of a physical therapy program

INTRODUCTION

Physical therapy (PT) may reduce the pain associated with provoked vestibulodynia (PVD) based on previous findings that pelvic floor muscle dysfunction (PFMD) is associated with PVD symptoms.

AIMS

The goals of this study were: (i) to determine whether women with and without PVD differ on measures of pelvic floor muscle (PFM) behavior; and (ii) to assess the impact of PT treatment for women with PVD on these measures.

METHODS

Eleven women with PVD and 11 control women completed an assessment evaluating PFM behavior using surface electromyography (SEMG) recordings and a digital intravaginal assessment. Women with PVD repeated the assessment after they had undergone eight PT treatment sessions of manual therapy, biofeedback, electrical stimulation, dilator insertions, and home exercises.

MAIN OUTCOME MEASURES

Superficial and deep PFM SEMG tonic activity and phasic activity in response to a painful pressure stimulus, PFM digital assessment variables (tone, flexibility, relaxation capacity, and strength).

RESULTS

At pretreatment, women with PVD had higher tonic SEMG activity in their superficial PFMs compared with the control group, whereas no differences were found in the deep PFMs. Both groups demonstrated contractile responses to the painful pressure stimulus that were significantly higher in the superficial as compared with the deep PFMs, with the responses in the PVD group being higher than those in control women. Women with PVD had higher PFM tone, decreased PFM flexibility and lower PFM relaxation capacity compared with control women. Posttreatment improvements included less PFM responsiveness to pain, less PFM tone, improved vaginal flexibility, and improved PFM relaxation capacity, such that women with PVD no longer differed from controls on these measures.

CONCLUSION

Women with PVD demonstrated altered PFM behavior when compared with controls, providing empirical evidence of PFMD, especially at the superficial layer. A PT rehabilitation program specifically targeting PFMD normalized PFM behavior in women with PVD.

The ACTIV study: acupuncture treatment in provoked vestibulodynia

INTRODUCTION

Provoked vestibulodynia (PVD) is a distressing genital pain condition affecting 12% of women. Treatment modalities vary and although vestibulectomy has the highest efficacy rates, it is usually not a first-line option. Acupuncture has a long history in the traditional Chinese medicine (TCM) system and operates on the premise that pain results from the blockage or imbalance of important channels. The main principle of treatment is to move Qi and blood to cease genital pain.

AIM

To explore effect sizes and feasibility in a pilot study of acupuncture for women with PVD.

METHODS

Eight women with PVD (mean age 30 years) underwent 10 1-hour acupuncture sessions. Specific placement of the needles depended on the woman's individual TCM diagnosis. TCM practitioners made qualitative notes on participants' feedback after each session. Main Outcome Measures. Self-reported pain (investigator-developed), pain-associated cognitions (Pain Catastrophizing Scale [PCS], Pain Vigilance and Awareness Questionnaire), and sexual response (Female Sexual Function Index) were measured before and after treatment sessions 5 and 10. Qualitative analyses of TCM practitioner notes were performed along with one in-depth case report on the experience of a participant.

RESULTS

A repeated measures analysis of variance revealed significant decreases in pain with manual genital stimulation and helplessness on the PCS. An examination of effect sizes also revealed strong (though nonsignificant) effects for improved ability to have intercourse and sexual desire. Qualitative analyses were overall more positive and revealed an improvement in perceived sexual health, reduced pain, and improved mental well-being in the majority of participants.

CONCLUSIONS

Effect sizes and qualitative analyses of practitioner-initiated interviews showed overall positive effects of acupuncture, but there were statistically significant improvements only in pain with manual genital stimulation and helplessness. These findings require replication in a larger, controlled trial before any definitive conclusions on the efficacy of acupuncture for PVD can be made.

Current perspectives in vulvodynia

Vulvodynia, or chronic vulvar pain, is a common but poorly understood condition. Although its etiology is not well understood, it appears to be multifactorial. As such, treatment options are targeted to reduce singular symptoms in a piecemeal fashion. A number of randomized, controlled trials have been conducted and at least one paper on combination therapy has been published; however, further systematic research is needed in order to more fully inform clinical practice.

The tampon test for vulvodynia treatment outcomes research: reliability, construct validity, and responsiveness

OBJECTIVE

A standardized tampon insertion and removal test, the Tampon Test provides an alternative to sexual intercourse pain as an outcome measure for vulvodynia research. We report upon the reliability, validity, and responsiveness to change of the Tampon Test as an outcome measure for vulvodynia clinical trials.

METHODS

Outcome measures were assessed in women enrolled in the Vulvar Vestibulitis Clinical Trial, a randomized clinical trial of oral desipramine and topical lidocaine effectiveness. Reliability estimates of the Tampon Test using the Kappa statistic evaluated week-to-week measures at baseline. Tampon Test construct and discriminant validity were assessed through correlation with other outcome measures. Patients' ability to regularly perform the Tampon Test was compared with regularity of reporting intercourse pain.

RESULTS

During the 2-week baseline phase, women with vulvodynia reported stable mean Tampon Test scores 4.6+/-2.6 (week -2); 4.6+/-2.7 (week -1); and 4.7+/-2.8 (week 0) with moderate week-to-week reliability (weighted Kappa 0.52). Over an 8-week phase of trial intervention, change in the Tampon Test measure significantly correlated to a number of outcome measures, including daily pain (r=0.42), intercourse pain (r=0.35), cotton swab vestibular pain (r=0.38), and the Brief Pain Inventory (r=0.49). Women with vulvodynia study participants performed the Tampon Test 96.3% of the requested time, which was twofold higher adherence than intercourse pain measurement (49.7%).

CONCLUSION

The Tampon Test reflects a real life experience that is reliable, with good construct validity as shown by the breadth of correlated outcome measures. The Tampon Test is an appropriate outcome measure for vulvodynia research that can be considered for use as the primary efficacy endpoint in clinical trials of treatments for vulvodynia.
