Recommendations for Self-Report Outcome Measures in Vulvodynia Clinical Trials

Pelvic Floor Physical Therapy is Self-Reported as a Minimally Effective, and Sometimes Harmful, Treatment for Pudendal Neuralgia: A Cross-Sectional Study

Objectives

Pudendal neuralgia (PN) is a sexual pain disorder characterized as pain of the genital and/or perineal regions, and despite the lack of clinical evidence supporting its use, pelvic floor physical therapy (PFPT) is a recommended treatment for PN.

Methods

An online anonymous cross-sectional survey was administered to participants through convenience sampling conducted on May 19 to September 19, 2023 to understand the self-reported efficacy of PFPT as a treatment for PN. Participants' measures included sociodemographics, Patient Global Impression of Change (PGIC), and satisfaction scores.

Results

The average self-reported PGIC score among participants was 4.6 ± 1.3 (n = 144), indicating no to minimal improvement in symptoms. Most participants (66%) scored 4 or 5, suggesting no change to minimal improvement. Twelve percent of participants scored 3 or lower, indicating worsening of symptoms, and only 22% scored 6 or 7, indicating much or very much improvement of symptoms. Participants who only participated in PFPT (n = 24) had a lower PGIC score of 4.4 ± 1.3. For self-reported satisfaction with PFPT as a treatment for PN, participants self-reported a score of 4.9 ± 3.0, indicating slight dissatisfaction. For those who experienced symptom improvement, the median number of sessions before noticing improvement was five sessions.

Conclusion

Based on self-reported results, PFPT is a minimally effective, and sometimes harmful, treatment for PN. Patients should receive greater transparency regarding the lack of efficacy of PFPT and its potential harm.

Development of a core outcome set for treatment studies for provoked vestibulodynia

BACKGROUND

There is an inconsistency in treatment outcomes used in clinical trials for provoked vestibulodynia (PVD), which makes it impossible to compare the effects of different interventions.

AIM

In this study, we completed the first step in creating a core outcome set (COS), defining what outcomes should be measured in clinical trials for PVD.

METHODS

Identification of outcomes used in studies was done by extracting data from clinical trials in a recently published systematic review and via review of clinical trials for PVD registered on ClinicalTrials.gov. The COS process consisted of 2 rounds of Delphi surveys and a consensus meeting, during which the final COS was decided through a modified nominal group technique.

OUTCOMES

Consensus on what outcomes to include in a COS for PVD.

RESULTS

Forty scientific articles and 92 study protocols were reviewed for outcomes. Of those, 36 articles and 25 protocols were eligible, resulting in 402 outcomes, which were then categorized into 63 unique outcomes. Participants consisted of patients, relatives/partners of patients, health care professionals, and researchers. Out of 463 who registered for participation, 319 and 213 responded to the first and second surveys, respectively. The consensus meeting consisted of 18 members and resulted in 6 outcomes for the COS to be measured in all treatment trials regardless of intervention: insertional pain (nonsexual), insertional pain (sexual), provoked vulvar pain by pressure/contact, pain-related interference on one's life, pain interference on sexual life, and sexual function.

CLINICAL IMPLICATIONS

Critical outcomes to be measured in clinical trials will allow for accurate comparison of outcomes across treatment interventions and provide solid treatment recommendations.

STRENGTHS AND LIMITATIONS

The major strengths of the study are the adherence to methodological recommendations and the intentional focus on aspects of diversity of participating stakeholders (eg, status such as patients with lived experience and researchers, inclusiveness with respect to sexual identity), the latter of which will allow for broader application and relevance of the COS. Among the limitations of the study are the low rate of participants outside North America and Europe and the lower response rate (about 50%) for the second Delphi survey.

CONCLUSION

In this international project, patients, health care professionals, and researchers have decided what critical outcomes are to be used in future clinical trials for PVD. Before the COS can be fully implemented, there is also a need to decide on how and preferably when the outcomes should be measured.

Hard flaccid syndrome symptoms, comorbidities, and self-reported efficacy and satisfaction of treatments: a cross-sectional survey

Hard flaccid syndrome (HFS) is a poorly understood condition with no formal consensus on its definition. We aimed to advance the understanding of HFS by evaluating symptom prevalence, cause of symptom onset, comorbidities, and self-reported efficacy and satisfaction with current treatments. An online, open, 42-question survey on Qualtrics with purposive and convenience sampling methods was conducted between May 9 and June 9, 2023 on participants self-identifying as having HFS. Participants were recruited through social media platforms. Only 58.0% of participants reported their HFS symptoms began following a specific incident/injury. Changes in penis shape/size (92.3%) and rigid penis when not erect (90.9%) were the most common complaints. Activities such as laying down and stretching improved symptoms in 73.0% and 44.1% of the participants, respectively, while masturbation and standing worsened symptoms in 75.9%, and 64.5% of the participants, respectively. Pudendal neuralgia (16.9%) was the most prevalent comorbid condition. Of those who participated in therapies, phosphodiesterase-5 (PDE5) inhibitor treatment had the highest patient global impression of change (PGIC) score (2.6 ± 1.1), indicating little to moderate improvement in symptoms. All other therapies scored between 1 and 2, indicating no change to little improvement in symptoms: pelvic floor physical therapy (PFPT) (1.8 ± 0.9), shockwave therapy (1.6 ± 1.1), diet/nutrition changes (1.6 ± 0.8), nerve blocks (1.6 ± 0.8), muscle relaxants (1.5 ± 0.6), anti-inflammatory medications (1.5 ± 0.7), cognitive therapy (1.4 ± 0.7), and nerve pain medications (1.4 ± 0.5). Overall, a direct injury to the penis may not necessarily be the only cause of HFS for some patients, and current therapies generally do not benefit most patients. A better understanding of the root causes of HFS and innovative treatment strategies are greatly needed for HFS patients.

Treating where it hurts-a randomized comparative trial of vestibule estradiol for postmenopausal dyspareunia

OBJECTIVE

To compare efficacies of two strengths of estradiol cream applied to the vulvar vestibule and use of silicone lubricant to reduce intercourse pain scores in postmenopausal women with moderate/severe dyspareunia.

METHODS

This pilot randomized comparative trial assigned 50 women to nightly applications of estradiol cream, 50 or 100 μg, for 12 weeks. We asked women to have lubricated penetration twice weekly, with intercourse or performing a tampon test. Pain, recorded in dairies, was rated using the 0-10 Numerical Rating Scale. We assessed biopsychosocial outcomes, urinary symptoms, and measured serum estradiol levels and endometrial stripe thicknesses. We performed physical examinations to determine tenderness levels of the vestibule, vagina, pelvic floor muscles, bladder, uterus, and adnexa. Comparisons were made using two-sample t test, Wilcoxon rank-sum test, or χ2 /Fisher's exact test.

RESULTS

Forty-seven women (94%), with a mean age of 59.7 years, completed the trial. The baseline median intercourse pain score was 8/10 (interquartile range, 6, 8). After 12 weeks, we measured no statistically significant difference between groups in the primary outcome, intercourse pain score, or any secondary outcome measure. For both groups together, the median intercourse pain score diminished by 50% after 4 weeks and 75% after 12 weeks ( P < 0.001). The most tender anatomic area, the vulvar vestibule, improved by 82% to 100% ( P < 0.001) with therapy. We did not measure a statistically significant difference in serum estradiol levels or endometrial stripe thickness between groups.

CONCLUSION

Estradiol cream applied to the vulvar vestibule, paired with precoital silicone lubricant, is a promising alternative to vaginal therapy for dyspareunia.

High-Intensity Laser Therapy (HILT) as an Emerging Treatment for Vulvodynia and Chronic Musculoskeletal Pain Disorders: A Systematic Review of Treatment Efficacy

High-intensity laser therapy (HILT) has been gaining popularity in the treatment of chronic musculoskeletal pain, including vulvodynia. The objective of this study was to critically appraise and synthesize the available evidence on the efficacy of HILT for reducing pain and improving function in vulvodynia and other chronic primary musculoskeletal pain conditions. Electronic databases and the grey literature were searched. Effects on pain intensity, function, and adverse events were assessed. One study investigating HILT in the treatment of vulvodynia and 13 studies on the treatment of chronic musculoskeletal pain were selected. The study assessing vulvodynia showed favorable results for reducing pain. Regarding chronic musculoskeletal pain, 12 out of the 13 studies selected consistently showed that HILT was more effective than the placebo/active comparator for reducing pain and improving function. The available effect sizes for pain showed large to huge effects. Similar effects were observed for function except for two studies showing moderate effects. The GRADE score was moderate. Conclusions: There are insufficient data to support the use of HILT in vulvodynia, but the promising results encourage further research. HILT appears to be effective in musculoskeletal pain conditions. More high-quality studies are needed to identify effective laser protocols.

Where does postmenopausal dyspareunia hurt? A cross-sectional report

OBJECTIVE

A common symptom of genitourinary syndrome of menopause (GSM) is dyspareunia, attributed to vulvovaginal atrophy. Our objective was to systematically describe the pain characteristics and anatomic locations of tenderness in a cohort with moderate/severe dyspareunia likely due to GSM.

METHODS

This cross-sectional study reports the baseline data of postmenopausal women with dyspareunia screened for an intervention trial of topical estrogen. Postmenopausal women not using hormone therapy who had moderate or severe dyspareunia were eligible if estrogen was not contraindicated. Biopsychosocial assessments were performed using the Vulvar Pain Assessment Questionnaire, and participants underwent a systematic vulvovaginal examination that included a visual assessment and cotton swab testing for tenderness rated using the Numerical Rating Scale (0-10). Vaginal pH and mucosal sensitivity were assessed; pelvic floor muscles and pelvic viscera were palpated for tenderness.

RESULTS

Fifty-five eligible women were examined between July 2017 and August 2019. Mean age was 59.5 ± 6.8 years, and duration of dyspareunia was 6.2 ± 4.3 years. The mean intercourse pain score was 7.3 ± 1.8, most often described as "burning" and "raw." Ninety-eight percent had physical findings of vulvovaginal atrophy. Median pain scores from swab touch at the vulvar vestibule (just outside the hymen) were 4 to 5/10, and topical lidocaine extinguished pain. Median vaginal mucosal pain was zero.

CONCLUSIONS

Participants described their pain as "burning" and "dry." Tenderness was most severe and most consistently located at the vulvar vestibule. Correlating the symptom of dyspareunia with genital examination findings may further our understanding of treatment outcomes for GSM.

Image-based documentation of vulvodynia pain location

Aims: Better documentation of vulvar pain is needed. We examined pain locations marked on general body and genital specific outlines among women with vulvodynia. Methods: 62 women (mean age 32.1 ± 9.5 years) with vulvodynia marked their pain on a digital genital specific outline (22 segments) and 59 of those women also marked their pain on a digital general body outline (48 segments). We used ImageJ software to determine body surface area (BSA) for each outline. Results: On the general body outline, 24/48 segments were marked; 22/22 segments were marked on the genital specific outline. There was a moderate correlation (r = 0.43; p = 0.001) between the BSA marked on the general body outline and the BSA marked on the genital area outline. Conclusions: Findings support concurrent validity of the BSA as a measure of pain location using either outline.

Feasibility and acceptability of somatocognitive therapy in the management of women with provoked localized vestibulodynia-ProLoVe feasibility study

Background

Provoked vestibulodynia (PVD) is a prevalent chronic pain condition especially among young women. Pain is localized to the vulvar vestibule and is provoked by touch or pressure, such as penetrative intercourse. PVD can have profound consequences, adversely affecting a woman’s sexual life, relation to her partner, and her psychological health. There is an urgent need for well-designed randomized clinical trials (RCTs) to identify the most effective interventions for this neglected women’s health condition.

Aims

The primary aim of this study is to assess the feasibility of undertaking a full-scale RCT of somatocognitive therapy (SCT), a multimodal physiotherapy intervention, for women with PVD. The secondary aim is to evaluate the implementation and acceptability of SCT and its potential treatment effectiveness in PVD. In the full-scale RCT, SCT will be compared to standard PVD treatment.

Methods

A multimethod feasibility study with a single-arm before-after trial and qualitative interviews. Ten women with PVD, aged 18–33 were recruited from the Vulva Clinic at Oslo University Hospital. The intervention took place at Oslo Metropolitan University. Participants were assessed at baseline, post-treatment, and the 8-month follow-up with the tampon test and self-report questionnaires. The main feasibility outcomes were evaluation of recruitment rate, adherence to assessment tools, and follow-up rate. The participants’ experiences with the primary outcome and the intervention were explored with semi-structured interviews.

Results

Ten out of 18 eligible patients were recruited over 11 weeks. None were lost to follow-up. Adherence to self-report questionnaires was excellent. Adherence to tampon tests and to the reporting of treatments was good, whereas adherence to the 14-day diary was poor. No adverse events were reported. The tampon test was suboptimal as a primary outcome. SCT was found to be an acceptable treatment, based on Global Perceived Effect scores and the participants’ experiences.

Conclusion

The findings suggest that it is feasible to deliver a full-scale RCT of the SCT intervention for women with PVD. Some changes are suggested to optimize the protocol, such as increasing recruitment sites, change of primary outcome measures, and adding a booster session.

Exclusive manual perineal rehabilitation with lidocaine 2% gel in the treatment of provoked vestibulodynia: results from a single-arm interventional study

As of now, there is no adequate therapeutic strategy for provoked vestibulodynia (PVD). Pelvic Floor Muscle Therapy (PFMT) is a widely used technique in general pelvic floor rehabilitation. The objective of this study is to examine the effects of exclusive manual perineal rehabilitation with lidocaine 2% gel on PVD. During the first session, recruited patients (n = 68; mean age 31 ± 8.6; range: 18–52) received a questionnaire (Q1) on general well-being and health, pain of the genital area, sexual function, and symptoms during vaginal penetration. This questionnaire was based on a generalised questionnaire on the quality of life, the Medical Outcomes Study 36-item (SF-36), the Female Sexual Function Index (FSFI), and the Visual Analogue Scale (VAS). A second identical questionnaire with an additional set of open-ended questions concerning the assessment of the treatment was collected after treatment (Q2). A total of 45 questionnaires were completed. Statistical results showed a significant improvement of all items before and after treatment (p < 0.001): perceived general well-being and health, perceived vulvar pain, perceived sexual function, and perceived vaginal penetration. In conclusion, exclusive manual perineal rehabilitation using lidocaine 2% gel seems to be a safe and effective treatment option for vulvodynia in women.

Internet-based Treatment for Vulvodynia (EMBLA) - A Randomized Controlled Study

BACKGROUND

Internet-based ACT (Acceptance and commitment therapy) treatment may improve accessibility and reduce stigma related to seeking health care, but there are a lack of studies investigating internet-based treatment using ACT principles for women with vulvodynia.

AIM

The aim of this study was to investigate the effects of an internet-based treatment of pain during intercourse for women with provoked vulvodynia compared with no intervention during the waiting period before clinical treatment.

METHODS

A multicenter randomized controlled trial was conducted during 2016 to 2020, in which 99 participants were included. Participants were randomized to either a 6 week guided internet-based treatment using ACT principles or usual care. Data were collected at baseline, 6 weeks after baseline, and approximately 10 months after baseline.

OUTCOMES

Pain-related (pain during intercourse, tampon test, impact of pain on sexual function) and pain behavior-related outcomes (attempts at intercourse, sexual activities besides intercourse, willingness to perform the tampon test, chronic pain acceptance questionnaire) were used as outcomes.

RESULTS

Treatment was efficacious in what concerns pain during intercourse and pain acceptance. Less pain during intercourse among women in the intervention group was observed at both post-treatment (primary endpoint, P = .01, Cohen's d = 1.4, 95% CI = 0.33, 2.4), and follow-up (P = .04). Absolut mean difference between groups for pain during intercourse at post-treatment was -2.84, (95 % CI = -4.91, -0.78), and -1.58 at follow-up, (95 % CI = -3.17, 0.02), where the intervention group rated less pain than controls. No differences between groups over time were found for tampon test measures or impact of pain on sexual function. There was a significant difference between groups at all timepoints indicating fewer attempts at intercourse among participants in the intervention group. At post-treatment, women who underwent internet-based treatment reported higher pain acceptance and a rise in activity engagement compared with the control group.

CLINICAL IMPLICATIONS

There is an indication that internet-based treatment could be incorporated into clinical practice as a complement to clinical treatment.

STRENGTHS & LIMITATIONS

Study strengths included using several forms of recruitment and an intervention built by different professions with long experience of treating patients with vulvodynia. High dropout rate was a limitation of this study.

CONCLUSION

Internet-based treatment may have an impact on pain during intercourse and positive effects on pain acceptance. However, conclusions must be drawn with caution due to the small sample size.

Comparing Self-Reported Pain During Intercourse and Pain During a Standardized Gynecological Exam at 12- and 24-Month Postpartum

BACKGROUND

There is limited information about the physical indicators and biopsychosocial predictors of self-reported pain during intercourse and pain during a gynecological examination at 12- and 24-month following childbirth.

AIM

This longitudinal study aimed to (i) Compare the findings from gynecological exams at 12- and 24-month postpartum for women with minimal vs clinically significant pain during intercourse; (ii) Assess the biomedical and psychosocial correlates of self-reported pain during intercourse and the vestibular pain index (VPI) from the cotton-swab test at 12- and 24-month postpartum; (iii) Establish the relationship between self-reported pain during intercourse and the cotton-swab test.

METHODS

Women (N = 97 at 12 months postpartum and N = 44 at 24-month postpartum) recruited from a local women's hospital completed online surveys in their first trimester of pregnancy and at 12- and 24-month postpartum to assess pain during intercourse and biopsychosocial variables. Those with clinically significant (pain ≥4/10 on a visual analogue scale) were matched with those reporting minimal pain (pain <3/10) and underwent a gynecological exam including a cotton-swab test. Descriptive analyses, multiple regressions, and bivariate correlations were conducted to address each of the study aims, respectively.

MAIN OUTCOME MEASURES

(i) Findings from the gynecological examination (ii) Numerical rating scale for the VPI; (iii) Visual analogue scale of pain during intercourse.

RESULTS

The majority of women in both pain groups had normal physical findings in the gynecological exam. Greater sexual distress and pain catastrophizing at 12- and 24-month postpartum were significantly associated with greater pain during intercourse at each time-point, respectively. Greater pain catastrophizing at 12 months postpartum was significantly associated with greater pain during the cotton-swab test at that time-point. Lower relationship satisfaction at 12 months postpartum was associated with greater VPI ratings at 24 months postpartum. Pain during intercourse and the VPI were moderately and positively correlated.

CLINICAL IMPLICATIONS

Addressing psychosocial variables may interrupt the maintenance of postpartum pain. Following an initial assessment, self-reported pain intensity may be a suitable proxy for repeated examinations.

STRENGTHS & LIMITATIONS

This study is the first to describe the physical findings and psychosocial predictors of pain during intercourse and the VPI at 12- and 24-month postpartum. The homogenous and small sample may limit generalizability.

CONCLUSION

There were no observable physical indicators of clinically significant postpartum pain during intercourse. Psychosocial variables were linked to women's greater postpartum pain during intercourse and VPI ratings.

Predictors and Moderators of Provoked Vestibulodynia Treatment Outcome Following a Randomized Trial Comparing Cognitive-Behavioral Couple Therapy to Overnight Lidocaine

Provoked vestibulodynia is a vulvar pain condition causing sexual dysfunction, affecting 8% to 10% of women. Our recently published randomized clinical trial (N = 108 couples) found that cognitive behavioral couple therapy (CBCT) and topical lidocaine reduced women's pain and associated sexual symptoms, with CBCT showing more benefits. Little is known about pretreatment predictors of treatment outcomes in couples sex therapy. In the current study, we examined women and their partners' pretreatment demographic (age, relationship length), clinical (pain duration, anxiety) and interpersonal (partner responses to pain, sexual goals) predictors/moderators of women's pain intensity, pain unpleasantness, and sexual function at posttreatment and 6-month follow-up. Longer relationship duration, lower anxiety in women, partner higher solicitousness and partner higher approach sexual goals predicted better pain outcomes for women with PVD irrespective of treatment condition. CBCT was more effective than lidocaine for improving women's sexual function at posttreatment when, at pretreatment, women had partners with higher anxiety and women reported lower approach sexual goals, whereas lidocaine was more effective for improving women's sexual function at follow-up when partners had higher approach sexual goals. Findings can assist clinicians in determining what treatment will be most beneficial for whom.

Comparing Vestibule Examination Techniques: Light Touch, Serial Forces, and the Lidocaine Test

OBJECTIVE

The purpose of this study was to compare techniques and pain scales that assess tenderness in the vulvar vestibule in provoked vestibulodynia, using the cotton swab test and a vulvalgesiometer, and assess topical lidocaine solution with each.

MATERIALS AND METHODS

This randomized study at a specialty vulvar clinic evaluated tender vestibules of reproductive-aged women with vestibulodynia using light rolling cotton swab touch at 6 sites and evaluated the vulvalgesiometer at 2 sites, randomizing the order of the initial tool. Participants reported pain using the Numerical Rating Scale 0-10 and the Verbal Pain Scale 0-3. With the vulvalgesiometer, the pain tolerance threshold was measured using forces of 10, 25, 50, 100, 200, and 300 g. After both initial tests, lidocaine 4% topical solution was applied for 3 minutes, and the swab test and vulvalgesiometer were repeated in the order initially performed, constituting the lidocaine test. Data analysis used t tests, Fisher exact tests, Wilcoxon signed rank tests, and Spearman rank correlation.

RESULTS

Sixteen patients completed the study, 8 starting with each instrument. Light swab touch evoked significant pain, and lidocaine reduced pain to zero or mild levels. The pain threshold was 25 g, and only 38% could tolerate testing past 100 g without lidocaine. The Verbal Pain Scale correlated well with the Numerical Rating Scale.

CONCLUSIONS

Light rolling cotton swab touch using the 4-item verbal scale can map vestibulodynia tenderness that can be extinguished by lidocaine, consistent with distinguishing a mucosal condition. Forces by vulvalgesiometer of greater than 100-200 g may evoke pain other than mucosal allodynia.

Predictors of vaginal penetration in women with Provoked Vestibulodynia

This study examined whether time, treatment type, baseline individual differences, and treatment satisfaction affected the vaginal intercourse trajectories of women with Provoked Vestibulodynia (PVD) before and after psychological treatment. Women (N = 130) who received CBT or MBCT completed questionnaires prior to and 2-4 weeks, 6-, and 12-months following treatment. The odds of women engaging in vaginal penetration increased by 31% at each assessment. Baseline individual differences and treatment satisfaction predicted maintenance of or re-engagement in vaginal penetration at post-treatment. Findings suggest that women who refrain from vaginal intercourse after treatment differ from women who continue or resume this activity.

The Tampon Test as a Primary Outcome Measure in Provoked Vestibulodynia: A Mixed Methods Study

BACKGROUND

Provoked vestibulodynia (PVD) is characterized by severe pain, often induced by penetrative sex. This may lead to women abstaining from sexual intercourse, hence the recording of pain intensity levels in PVD research is often challenging. The standardized tampon test was designed as an alternative outcome measure to sexual intercourse pain and has frequently been used in clinical studies.

AIM

The aim of this mixed methods study is to evaluate the tampon test as a primary outcome measure for an upcoming randomized clinical trial for women with PVD.

METHODS

An explanatory sequential design was applied, integrating quantitative and qualitative methods. In phase one, pain intensity levels were evaluated with the tampon test amongst 10 women, aged 18-33, with PVD. The test was repeated on day 1, 7 and 14. Pain intensity was rated on the Numerical Rating Scale (NRS), (0-10), 10 being worst possible pain. In phase two, the participants' experiences with the test were explored with semi-structured interviews using a descriptive and inductive qualitative design. All participants were recruited from the Vulva Clinic, Oslo University Hospital, Norway.

OUTCOMES

The tampon test data and interviews were brought together to see how the interviews could refine and help to explain the quantitative findings.

RESULTS

The tampon test data demonstrated large intra- and inter-individual variability. Median tampon pain intensity was 4.5 (min=1.7; max=10; Q1=2.5; Q3=6). Many experienced the test as an inadequate representation of pain during intercourse as it was less painful, different in nature and conducted in an entirely different context. Four participants had a mean score of four or lower on the NRS, whilst concurrently reporting high levels of pain during sexual intercourse.

CLINICAL IMPLICATIONS

The findings indicate that the tampon test may underestimate severity of pain among some women with PVD. Participants with low pain scores would be excluded from studies where the tampon test is part of the trial eligibility criteria, even though severe pain was experienced during sexual intercourse. Large intra-individual variability in pain scores also reduces the test's ability to register clinical meaningful changes and hence necessitates repeated measurements per assessment time point.

CONCLUSION

Although the tampon test has many advantages, this study indicates several potential problems with the application of the test as a primary outcome measure in PVD. In our opinion the test is most useful as a secondary outcome, preferably undertaken repeatedly in order to increase precision of the pain estimation. Kaarbø MB, Danielsen KG, Haugstad GK, et al. The Tampon Test as a Primary Outcome Measure in Provoked Vestibulodynia: A Mixed Methods Study. J Sex Med 2021;18:1083-1091.

Exploring Relationships Between Genito-Pelvic Pain/Penetration Disorder, Sex Guilt, and Religiosity Among College Women in the U.S

INTRODUCTION

Despite a growing body of research on psychosocial factors in Genito-Pelvic Pain/Penetration Disorder (GPPPD) during sexual intercourse, there are few studies examining adolescent and young adult women's experiences with painful sex and the effects of religiosity, sexual education, and sex guilt.

AIM

The purpose of the study was to examine the occurrence of GPPPD among sexually active female college students, including psychosocial factors of religiosity and religious practice, sexual education, sex guilt, and sexual distress.

METHODS

Data were collected from 974 college women from a university in the Northeastern U.S. We limited our sample to sexually active women (n = 593, 60.9%; mean age: 18.96) who responded to the questionnaire item, "In general, do you feel pain with sexual intercourse?" Participants completed the Female Sexual Function Index (FSFI), Female Sexual Distress Scale (FSDS), Revised Mosher Sex Guilt Scale, Abbreviated Santa Clara Strength of Religious Faith Questionnaire, 10-item Gender Role Beliefs Scale, and measures on sexual wellness and practice and sexual education experiences. Data were analyzed using standard bivariate and regression analyses as well as path analysis.

MAIN OUTCOME MEASURES

Women were asked, "In general, do you feel pain with sexual intercourse?" and categorized into one of three pain groups: occasional (10%-25% of the time), frequent (50% or more), and no pain (less than 10%).

RESULTS

GPPPD with sex was prevalent among young college women, with 113 (19.1%) reporting frequent pain and 143 (24.1%) occasional pain (control n = 337, 56.8%). Numerous statistically significant factors were identified, including frequency of sex, ability to orgasm, sensations during intercourse, presence of a steady sexual partner, expectations of painful sex, sex guilt, and sexual distress. Sex guilt acted as full mediator between religiosity and painful sex.

IMPLICATIONS

Healthcare providers should proactively initiate conversations with young female patients about painful intercourse to identify issues and normalize language on pain with sex. Educators are urged to teach evidence-based information on pain-free and guilt-free sexual experiences inside and outside religious contexts.

CONCLUSION

Painful sex affects adolescent and young adult women at a similar rate as non-college adult women and while religiosity does not directly impact young women's GPPPD, religiosity does lead to painful sex if it causes sex guilt. Further research is needed into the mechanisms of religion-based sexual shaming and among religiously conservative women who practice abstinence until marriage.

Long-Term Efficacy of Physical Therapy for Localized Provoked Vulvodynia

Purpose

The origin of provoked vulvodynia (PV), the main cause of entry dyspareunia, remains unclear, and the treatment is empiric. In this study, we aimed to investigate the long-term effects of physical therapy on PV in subjects using questionnaire concerning PV symptoms immediately after physical therapy and at least 10 years later.

Patients and Methods

This study included a total of 24 women diagnosed with PV and referred by their primary physicians to Maccabi Physical Therapy Clinic for pelvic floor rehabilitation between 2004 and 2008. Criteria such as pain relief, sexual functioning, and treatment satisfaction were assessed.

Results

The average pain scores of the 24 participants reduced significantly after therapy, and 42% had no pain between treatment and the time of survey. Eighty-three percent did not undergo additional treatment after the initial physical therapy and reported high or very extremely high levels of pain reduction following treatment. Multiple regression analysis found that onset type of PV and age were not associated with the treatment outcome (p = 1.0).

Conclusion

Physical therapy is an effective long-term treatment for primary or secondary PV, resulting in pain reduction and improved sexual function.

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.

The Vulvodynia Experience Questionnaire: Qualitative Development of a New Patient-Reported Outcome Measure for Vulvodynia

INTRODUCTION

Vulvodynia is defined as vulvar pain of at least 3 months duration without a clear identifiable cause. There are currently no validated questionnaires that assess the experience of women with localized vulvodynia of the vestibule (vestibulodynia, previously known as vulvar vestibulitis) that meet the requirements of the Food and Drug Administration's Patient Reported Outcome (PRO) Guidance.

AIM

To develop a new content-valid PRO assessment in accordance with the Food and Drug Administration's PRO guidance to assess the symptoms and impacts of localized vulvodynia.

MATERIAL AND METHODS

Participants were recruited for concept elicitation interviews (ie, interviews with open-ended questions with the goal of eliciting volunteered data about the symptoms and impacts of vulvodynia). Participants were identified as having localized vulvodynia by clinicians who were experts in treating vulvar disorders. Eligibility was confirmed by the recruiting clinician, and informed consent was obtained; participants were then scheduled for in-person interviews. 25 participants were interviewed from United States (US). After concept elicitation interviews, the draft Vulvodynia Experience Questionnaire (VEQ) was developed based on the results. Cognitive interviews were conducted with 20 participants from US sites to assess the content validity of the VEQ (eg, interpretation and clarity of the items, relevance of concepts). The VEQ was further revised after cognitive interviews. All interviews were conducted face-to-face, audio-recorded, transcribed verbatim, anonymized, and analyzed using a qualitative data analysis software program.

RESULTS

17 unique symptoms and 32 unique impacts were reported during concept elicitation interviews. Pain (n = 25, 100%) and burning (n = 24, 96%) were the most frequently reported symptoms of localized vulvodynia, and negative impact on emotional well-being (n = 25, 100%) was the most frequently reported impact. After analysis, item generation, and cognitive interviews, the resulting VEQ v2.0 contains 3 parts (part 1, pain; part 2, associated symptoms; part 3, impacts) with a total of 25 items that measure the most frequently reported symptoms and impacts of localized vulvodynia.

STRENGTH AND LIMITATIONS

The VEQ is a multidimensional assessment of the core symptoms and impacts of localized vulvodynia that, after additional psychometric testing including the ability to detect change, may be used in clinical trials to characterize the benefits of novel treatments. The VEQ requires additional testing to establish its cultural relevance and linguistic validity in other countries.

CONCLUSION

The VEQ is a novel method of collecting information on localized vulvodynia symptoms and impacts that may be suitable for use in clinical trials after psychometric testing.

Persistent Genital Arousal Disorder: a Biopsychosocial Framework

Purpose of Review

Persistent genital arousal disorder (also referred to as genitopelvic dysesthesia or PGAD/GD) is a distressing and largely underrecognized condition characterized by persistent, unwanted genital arousal (sensations, sensitivity, vasocongestion) in the absence of subjective/cognitive arousal and sexual desire. The purpose of this review is to summarize recent findings on biological and psychosocial factors in PGAD/GD as they pertain to the assessment and treatment of this condition. These findings will be considered within a biopsychosocial framework, for the purposes of considering next steps for clinical and research efforts.

Recent Findings

A small number of studies have recently examined potential biological aetiologies for PGAD/GD: pharmacological agents, spinal pathology and peripheral nerve involvement. Recent studies have also found that PGAD/GD is associated with a significant negative impact on psychosocial wellbeing and daily functioning as compared to symptom-free individuals. In addition, these results highlight cognitive/affective responses to symptoms (e.g. catastrophizing of symptoms) that may influence outcomes. However, biological and psychological research are rarely integrated in these studies, despite the interrelationship between these factors.

Summary

Although PGAD/GD was first described in the scientific literature almost two decades ago, most research on PGAD/GD is presented in the form of case studies. Prospective treatment trials that integrate biopsychosocial factors are needed in order to provide effective and efficient care to this population. This research would be facilitated by the development of a patient-reported outcome measure, as well as greater education/awareness among healthcare providers and the public about this distressing condition.

Vulvodynia

Vulvodynia is a condition that occurs in 8-10% of women of all ages and is characterized by pain at the vulva that is present during sexual and/or non-sexual situations. Diagnosis is established through careful medical history and pelvic examination, including the cotton-swab test. The onset and maintenance of vulvodynia involves a complex interplay of peripheral and central pain mechanisms, pelvic floor muscle and autonomic dysfunction, anxiety, depression and childhood maltreatment as well as cognitive-affective, behavioural and interpersonal factors. Given the absence of empirically supported treatment guidelines, a stepwise approach of pelvic floor physical therapy and cognitive behavioural therapy as well as medical management is suggested, with surgery as the last option. Vulvodynia has a negative effect on the quality of life of women and their partners, and imposes a profound personal and societal economic burden. In addition, women with vulvodynia are more likely to report other chronic pain conditions, which further alters their quality of life. Future efforts should aim to increase girls', women's and healthcare professionals' education and awareness of vulvodynia, phenotype different subgroups of women based on biopsychosocial characteristics among more diverse samples, conduct longitudinal studies and improve clinical trial designs.

Biased Partner Perceptions of Women's Pain Self-Efficacy in Postpartum Pain During Intercourse: A Dyadic Longitudinal Examination

Postpartum pain during intercourse is a prevalent and distressing problem that has substantial consequences for affected couples. Partner perceptions-such as how partners perceive women's pain self-efficacy-contribute to an individual's pain experience. This study examined whether partners under- or over-estimate women's intercourse pain self-efficacy at 3-months postpartum and the implications of this bias for women's pain and couples' sexual functioning at 3- and 6-months postpartum. Women who reported pain during intercourse and their partners (N = 89 couples) completed online measures assessing pain self-efficacy (own or partner perceptions), pain intensity, and sexual functioning at 3- and 6-months postpartum. Analyses were based on the Truth and Bias Model of Judgement and Response Surface Analysis. Partners were accurate in their estimates of women's pain self-efficacy (ie, their estimates were positively correlated with women's), but they also underestimated it by perceiving women to be less efficacious than women themselves reported. When couples showed greater agreement for lower levels of pain self-efficacy at 3 months, women reported greater pain intensity and both partners reported poorer sexual functioning at 3- and 6-months postpartum. Findings may inform interventions that promote pain self-efficacy to improve partner support and couples' sexual functioning. PERSPECTIVE: When women report-and their partners perceive-low levels of women's self-efficacy for managing painful intercourse, women report greater postpartum pain during intercourse and couples indicate poorer sexual functioning. These findings suggest that interventions aimed at promoting couples' agreement at high pain self-efficacy may improve their adjustment to postpartum pain.

Recommendations for the Study of Vulvar Pain in Women, Part 2: Methodological Challenges

INTRODUCTION

Chronic vulvar pain is a multidimensional condition with great variability in clinical presentation among affected women. In a companion article, part 1, we reviewed and recommended assessment and measurement tools for vulvar pain and related outcomes with a view toward improving consistency and comparison across studies. Yet methodological challenges to conducting research with this population remain and can further hinder conclusions regarding etiology and treatment.

AIM

To discuss methodological challenges to conducting vulvar pain research alongside recommended solutions.

METHODS

The expert authors reviewed the scientific evidence related to the study of vulvar pain and made decisions regarding methodological challenges and mitigation strategies via discussion and consensus.

MAIN OUTCOME MEASURE

We articulated key challenges to conducting research in this area and formulated recommendations for mitigating these challenges.

RESULTS

Challenges to the field include selection and sample biases, heterogeneity of the condition, inclusion of the partner, and neglect of the multidimensional aspects of vulvar pain. 2 key recommendations are more careful and detailed tracking and characterization of research samples and greater multidisciplinary collaboration to better capture the complexity of chronic vulvar pain.

CLINICAL IMPLICATIONS

This methodological critique points to several challenges to clinical research with populations struggling with chronic vulvar pain and makes suggestions for how to mitigate these issues.

STRENGTH & LIMITATIONS

Comments in this expert review raise awareness regarding core challenges to the study of vulvar pain and can inform study design of clinical research with this population. The content of this review is based on expert knowledge and opinion rather than a formal systematic review or extended consultation process.

CONCLUSION

A careful reflection upon methodological challenges facing clinical research of vulvar pain and ways to mitigate such challenges is crucial for improving the quality, generalizability, and uptake of research findings.

Pain, Anxiety, Depression, and Quality of Life in Patients with Vulvodynia

BACKGROUND/AIMS

The term vulvodynia refers to vulvar pain of unknown origin lasting at least 3 months. Psychiatric comorbidities are a common feature and, along with pain, may severely affect patients' wellbeing. We aimed to determine the characteristics of pain in vulvodynia, to correlate characteristics with symptoms of anxiety and depression, and to analyse the impact of these factors on patients' quality of life.

METHODS

This cross-sectional observational study analysed pain, anxiety, and depression and the effects of these factors on quality of life. Pain, anxiety, and depression were assessed using validated tools in 110 women.

RESULTS

Statistical analyses found correlations between pain and anxiety and between anxiety and worsened quality of life. Patients often reported stinging, burning, pain, itching, and dyspareunia, pointing to the importance of temporal, localisation, punctate pressure, thermal, tactile sensitivity, and emotional tension characteristics. Most patients had severe pain related to psychiatric comorbidities and decreased quality of life.

CONCLUSION

Using descriptors of pain quality and assessing anxiety and depression might help to define subgroups of patients that may benefit from different therapeutic approaches and thus enable treatments to be tailored to individual patients.

A Descriptive and Longitudinal Analysis of Pain During Intercourse in Pregnancy

INTRODUCTION

Pain during vaginal intercourse in pregnancy has largely been ignored despite physiological and psychological components of pregnancy that may be associated with its onset and persistence.

AIM

The current study aimed to determine the prevalence and the characteristics of clinically significant pain during intercourse in the second (18-24 weeks) and third (32-36 weeks) trimesters of pregnancy.

METHODS

Pregnant women (N = 501) recruited from a local women's hospital completed an online survey in the second and third trimesters of their pregnancy regarding the presence, intensity, and characteristics of pain during intercourse. Women with clinically significant pain (ie, pain greater than or equal to 4 of 10 on a numerical rating scale) were grouped according to whether the pain was resolved, persistent, or new onset across the 2 pregnancy time points. Following guidelines outlined by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT), we conducted a descriptive analysis assessing the intensity and characteristics (eg, quality, onset, degree of improvement over time, and treatment strategies utilized) of clinically significant pain during intercourse.

MAIN OUTCOME MEASURE

The main outcome measures in this study were the prevalence, intensity, and characteristics of clinically significant pain during intercourse.

RESULTS

Overall, 21% of pregnant women (106/501) reported clinically significant pain during intercourse. We found that 22% (N = 16/106) of women who had this pain at 20 weeks reported that it had resolved at 34 weeks, 33% (40/106) reported persistent pain at both time points, and 46% (50/106) reported new onset of pain during intercourse at 34 weeks. The majority of women across all pain groups reported that the pain began during pregnancy and remained at the same intensity. Most women reported not using any pain management strategies to cope with their pain.

CLINICAL IMPLICATIONS

One in 5 women experienced clinically significant pain during intercourse in pregnancy, with the majority of women not seeking treatment.

STRENGTHS & LIMITATIONS

This study is the first to comprehensively assess and describe the prevalence and characteristics of clinically significant pain during intercourse across 2 time points in pregnancy using IMMPACT guidelines. Small sample sizes in our pain groups may limit the generalizability of pain characteristics.

CONCLUSION

Findings suggest that many pregnant women in this study experienced significant pain during intercourse in pregnancy. Understanding the characteristics of this pain may improve its identification by health care providers and inform better prevention and treatment recommendations.

Motor Function and Perception of Health in Women with Provoked Vestibulodynia

BACKGROUND

Provoked vestibulodynia (PVD) is a prevalent and disabling condition in women that may be associated with reduced quality of life and impairment of physical functioning.

AIM

To investigate whether women with PVD have different motor functions, posture and breathing patterns, and whether they perceive their physical health differently, compared with asymptomatic controls.

METHODS AND MAIN OUTCOME MEASURE

The Standardized Mensendieck Test (SMT) and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) were used to assess differences between 35 women with PVD and 35 healthy controls.

RESULTS

There were no statistically significant differences in any of the 5 motor domains of the SMT between the women with PVD and those without PVD: standing posture, 4.0 (0.6) vs 5.0 (0.6); gait, 4.7 (0.6) vs 4.8 (0.6); movement, 4.8 (0.8) vs 5.1 (0.6); sitting posture, 4.7 (1.0) vs 4.9 (0.8); respiration, 4.7 (1.0) vs 4.7 (0.9). Women with PVD scored significantly lower in all domains on the SF-36 (adjusted Bonferroni P = .002) except physical functioning.

CLINICAL IMPLICATIONS

Given the lack of difference in the SF-36 physical functioning domain and in all 5 domains of the SMT between women with PVD and those without PVD, the value of interventions focusing on general physical function is unclear.

STRENGTHS & LIMITATIONS

A study strength is the use of an assessor-blinded case-control design, trained physiotherapists to conduct the tests, and valid and reliable outcome measures. A limitation is the homogeneity of the sample of young nulliparous women, which limits the generalizability of our findings to other study populations.

CONCLUSION

Young nulliparous women with PVD did not score differently from a group of healthy controls on assessment of overall physical functioning or on standing posture, gait, movement, sitting posture, and respiration. However, the score for perception of general health was lower in the women with PVD compared with controls. I. Næss, H.C. Frawley, K. Bø.

Sexual Distress Mediates the Associations Between Sexual Contingent Self-Worth and Well-Being in Women With Genitopelvic Pain: A Dyadic Daily Experience Study

Provoked vestibulodynia (PVD), a common cause of women's genitopelvic pain, is associated with poorer psychological and sexual well-being in affected couples. Greater sexual contingent self-worth (CSW)-defined as self-esteem that is dependent on the perceived success or failure of a sexual relationship-has been linked to poorer well-being in a cross-sectional study of couples coping with PVD. This study aimed to examine whether daily sexual distress mediated the associations between greater sexual CSW and lower sexual satisfaction and greater anxiety, depressed mood, and women's pain in affected couples. Women (N = 125) diagnosed with PVD and their partners completed the Sexual CSW Scale and then online daily surveys for eight weeks measuring sexual distress, sexual satisfaction, anxiety, depressed mood, and women's pain during intercourse. Multilevel analyses were based on the actor-partner interdependence model (APIM). For women who had higher sexual CSW (compared to lower sexual CSW), on sexual activity days when their sexual distress was higher, they reported lower sexual satisfaction and greater anxiety, depressed mood, and pain (compared to their average level across all sexual activity days). Findings suggest that daily sexual distress may be one pathway between greater sexual CSW and poorer day-to-day well-being in women with PVD.

What Do Different Measures of Pain Tell Us? A Comparison in Sexually Active Women With Provoked Vestibulodynia

INTRODUCTION

Studies of pain measurement in women with provoked vestibulodynia (PVD) use various methods of capturing pain intensity. The degree to which these different measures of pain correspond with one another is not known.

AIM

To compare 3 different measures of pain intensity in sexually active women with PVD participating in a clinical treatment study.

METHODS

A total of 64 women (mean age 30.9 years) provided baseline measures of pain intensity using (i) a numeric rating scale that provided a self-report of pain during recalled vaginal penetration; (ii) the pain subscale of the female sexual function index; and (iii) pain elicited with a vulvalgesiometer, an objective method of eliciting pain.

MAIN OUTCOME MEASURE

Correlations among these 3 measures of pain were moderate in size (range r = 0.39-0.61). Moreover, the numeric rating scale of pain was more likely to be associated with self-reported measures of pain catastrophizing and pain hypervigilance than were scores on the pain subscale of the female sexual function index or scores from the vulvalgesiometer.

CLINICAL IMPLICATIONS

Overall, there was a moderate level of correlation between different often-used measures of pain in women with PVD. These findings suggest that, in addition to measuring a common dimension, these different measures tap into different aspects of women's experiences with vulvovaginal pain, and researchers should consider how the chosen measure addresses their primary research question when selecting pain measures in future PVD research.

STRENGTHS & LIMITATIONS

A strength of this study was the large sample size (n = 64 sexually active women) who had received confirmed clinical diagnoses of PVD. 1 limitation of the findings is that our self-report outcome measures are based on retrospective ratings of pain over 4 weeks, and it is possible that other variables, such as mood, could have impacted scores on these measures.

CONCLUSION

This study showed statistically significant and moderate correlations among 3 different pain measures widely used in PVD research and treatment. In addition, only 1 pain measure showed a significant independent association with emotion function measures. These findings provide a rationale for including multiple measures of pain and emotional function in treatment outcome studies of PVD. Wammen Rathenborg FL, Zdaniuk B, Brotto LA.

Outcome Measurement Instruments for Provoked Vulvodynia: A Systematic Review

OBJECTIVE

The objective of this study was to detail the outcome measurement instruments used in randomized control trials and observational studies investigating therapeutic interventions for provoked vulvodynia.

MATERIALS AND METHODS

We searched Ovid Medline, Embase, Emcare, and PyschINFO libraries from database inception through April 2017. We included randomized control trials and observational studies of provoked vulvodynia that used instruments to measure the outcome of therapeutic interventions.

RESULTS

A total of 2299 articles were retrieved and 25 were eligible for inclusion in accordance with the selection criteria. The included studies measured 26 different outcomes, using 110 outcome measurement instruments. Patient-reported outcomes were most commonly measured (144/166, 86%), followed by physician-reported outcomes (20/166, 12%). The most commonly measured outcomes were patient-reported psychological impact of disease (27/166, 16%), patient-reported improvement in dyspareunia (25/166, 15%), and patient-reported reduction in pain (24/166, 14%). The Pain Catastrophizing Scale, the Beck Depression Inventory, and the State Trait Anxiety Questionnaire were the most commonly used instruments to measure psychological impact.The most commonly measured clinician-rated outcome was an improvement in pain (17/166, 10%), which was most frequently assessed by the cotton swab test. Only 34 (31%) outcome measurement instruments were specific to vulvodynia (26/110, 23%) or sexual functioning (8/110, 7%).

CONCLUSIONS

There is a wide range of outcome measurement instruments used in provoked vulvodynia studies, resulting in inconsistency of reporting and difficulty in comparing and combining findings for systemic review. There is a pressing need for the development of validated, reliable instruments and consensus on a core outcome set for further research purposes.

Research Design Characteristics of Published Pharmacologic Randomized Clinical Trials for Irritable Bowel Syndrome and Chronic Pelvic Pain Conditions: An ACTTION Systematic Review

Chronic pain conditions occurring in the lower abdomen and pelvis are common, often challenging to manage, and can negatively affect health-related quality of life. Methodological challenges in designing randomized clinical trials (RCTs) for these conditions likely contributes to the limited number of available treatments. The goal of this systematic review of RCTs of pharmacologic treatments for irritable bowel syndrome and 3 common chronic pelvic pain conditions are to: 1) summarize the primary end points and entry criteria, and 2) evaluate the clarity of reporting of important methodological details. In total, 127 RCTs were included in the analysis. The most common inclusion criteria were a minimum pain duration (81%), fulfilling an established diagnostic criteria (61%), and reporting a minimum pain intensity (42%). Primary end points were identified for only 57% of trials. These end points, summarized in this article, were highly variable. The results of this systematic review can be used to inform future research to optimize the entry criteria and outcome measures for pain conditions occurring in the lower abdomen and pelvis, to increase transparency in reporting to allow for proper interpretation of RCT results for clinical and policy applications, and to facilitate the aggregation of data in meta-analyses.

PERSPECTIVE

This article summarizes entry criteria and outcome measures and the clarity of reporting of these important design features in RCTs of irritable bowel syndrome and 3 common chronic pelvic pain conditions. These results can be used to improve design of future trials of these largely unaddressed pain conditions.

Daily Anxiety and Depressive Symptoms in Couples Coping With Vulvodynia: Associations With Women's Pain, Women's Sexual Function, and Both Partners' Sexual Distress

Vulvodynia is a idiopathic vulvovaginal pain condition that interferes with the sexual and mental health of affected couples. Research has underscored that psychological factors, such as anxiety and depression, are associated with its development and maintenance and related sexual impairment. However, the daily role of anxiety and depressive symptoms in the pain and sexuality outcomes of couples coping with vulvodynia is not well understood. Using a dyadic daily experience method, 127 women (mean age = 26.21, SD = 6.24 years) diagnosed with vulvodynia and their partners (mean age = 27.44, SD = 7.29 years) reported on anxiety and depressive symptoms, pain, sexual function, and sexual distress over a period of 8 weeks. Multilevel modeling was used to examine how daily deviations in anxiety and depressive symptoms from a participant's own mean were associated with pain, sexual function, and sexual distress. On days of sexual activity, when women reported higher anxiety and depressive symptoms (compared with their average), they reported greater pain and lower sexual function. On days of sexual activity, when women reported higher depressive symptoms, they reported greater levels of sexual distress, and when partners reported higher anxiety and depressive symptoms, women as well as partners reported greater levels of sexual distress. Results suggest that daily anxiety and depressive symptoms play a role in women's experience of vulvodynia-related pain, women's sexual function, and the couple's sexual distress. Targeting daily anxiety and depressive symptoms could enhance the efficacy of psychological interventions for vulvodynia.

PERSPECTIVE

This article examines the daily associations between anxiety and depressive symptoms, women's pain, sexual function, and sexual distress among couples coping with vulvodynia. Findings contribute to refine the biopsychosocial model of pain, showing that daily affective factors are associated with pain and sexual well-being.

Vulvodynia: a consideration of clinical and methodological research challenges and recommended solutions

Vulvodynia, an idiopathic chronic vulvar pain, is a prevalent genital pain condition that results in significant impairment to sexual, relational, and psychological functioning of affected women and their romantic partners. Despite its high prevalence, there remain gaps in knowledge and health care access for women coping with vulvodynia, given its varied clinical presentation and no widely accepted treatment protocol. The past several decades have seen important advancements in understanding vulvodynia and developing effective treatments; however, progress has been impeded due to clinical and methodological challenges in conducting research with this vulnerable population. This review presents a brief overview of vulvodynia correlates, consequences, etiology, and treatment, and then turns its attention to considering the clinical and methodological challenges that hinder vulvodynia research. Identifying these barriers alongside potential mitigating solutions is essential to developing empirically supported treatments for all women affected by vulvodynia, across all age and minority groups. Potential solutions will require researchers to broaden eligibility criteria, examine subgroups of women, and expand definitions of treatment outcomes, and may be best facilitated by more active collaboration among research groups and across relevant disciplines. Engagement in these solutions may contribute to more representative findings and the development and dissemination of empirically based treatment options for this complex pain condition.

Systematic Review of the Effectiveness of Physical Therapy Modalities in Women With Provoked Vestibulodynia

INTRODUCTION

Pelvic floor muscle physical therapy is recommended in clinical guidelines for women with provoked vestibulodynia (PVD). Including isolated or combined treatment modalities, physical therapy is viewed as an effective first-line intervention, yet no systematic review concerning the effectiveness of physical therapy has been conducted.

AIM

To systematically appraise the current literature on the effectiveness of physical therapy modalities for decreasing pain during intercourse and improving sexual function in women with PVD.

METHODS

A systematic literature search using PubMed, Scopus, CINHAL, and PEDro was conducted until October 2016. Moreover, a manual search from reference lists of included articles was performed. Ongoing trials also were reviewed using clinicaltrial.gov and ISRCTNregistry. Randomized controlled trials, prospective and retrospective cohorts, and case reports evaluating the effect of isolated or combined physical therapy modalities in women with PVD were included in the review.

MAIN OUTCOME MEASURES

Main outcome measures were pain during intercourse, sexual function, and patient's perceived improvement.

RESULTS

The literature search resulted in 43 eligible studies including 7 randomized controlled trials, 20 prospective studies, 5 retrospective studies, 6 case reports, and 6 study protocols. Most studies had a high risk of bias mainly associated with the lack of a comparison group. Another common bias was related to insufficient sample size, non-validated outcomes, non-standardized intervention, and use of other ongoing treatment. The vast majority of studies showed that physical therapy modalities such as biofeedback, dilators, electrical stimulation, education, multimodal physical therapy, and multidisciplinary approaches were effective for decreasing pain during intercourse and improving sexual function.

CONCLUSION

The positive findings for the effectiveness of physical therapy modalities in women with PVD should be investigated further in robust and well-designed randomized controlled trials.
