Not all lasers are the same: a scoping review evaluating laser therapy for vulvodynia.

INTRODUCTION: Lasers are commonly used for treating various vaginal/vulvar conditions. To date, there is to our knowledge no available literature review on the effects of different types of lasers for the treatment of women with vulvodynia, a condition that causes chronic pain in the vulvar area. OBJECTIVES: We sought to review the literature and summarize the existing published evidence regarding the effects of lasers for the treatment of women with vulvodynia. METHODS: A scoping review with a systematic search was conducted that included studies investigating the use of laser treatment in women with vulvodynia. The National Heart, Lung, and Blood Institute Study Quality Assessment Tools were used for the quality assessment. The type of laser, effects on pain and function, and participants' perceived improvement as well as adverse events were analyzed. RESULTS: Eight studies investigating laser therapy were included in the analysis: 1 randomized controlled trial, 5 before-after studies, 1 nonrandomized intervention study, and 1 case report. Several types of laser therapies were identified, ranging from mild noninvasive photobiomodulation to more invasive ablative procedures. Of the 6 studies that included pain outcomes, 3 studies showed statistically significant improvements from baseline to follow-up, and 3 demonstrated a reduction in pain from subjectively interpreted data. Similarly, each of the 2 studies investigating sexual function also reported an improvement (based only on subjective interpretation). Of the 2 studies with a comparison group, neither study was adequately powered to detect between-group differences. Furthermore, 57%-78% of participants reported improvement, with 1 study showing a greater statistically significant improvement in the low-level laser therapy patient group compared to the sham laser group. Outcomes and adverse events varied depending on the type of laser used. CONCLUSIONS: Although these studies demonstrated some benefits of laser therapy for the treatment of vulvodynia, these findings should be interpreted with caution given the scarcity of the included studies that were robust and sufficiently powered. Future research should focus on conducting well-designed randomized controlled trials to evaluate the efficacy of different types of lasers in the treatment of vulvodynia.

Effectiveness of Two Transcutaneous Electrical Nerve Stimulation (TENS) Protocols in Women with Provoked Vestibulodynia: A Randomized Controlled Trial.

BACKGROUND: Vestibulodynia (VBD) is the most common form of vulvodynia. Because VBD is a pain disorder, transcutaneous electrical nerve stimulation (TENS) can be used as treatment. This study aims to evaluate the effects of two-parameter combinations (frequency and pulse duration) of TENS in reducing pain intensity and dyspareunia in VBD. METHODS: A randomized, double-blind, controlled trial was conducted to study the effect of two different electrical stimulation treatment regimens on women with VBD receiving domiciliary TENS. Outcomes were the mean change from baseline at 60 and 120 days of burning/pain and dyspareunia (VAS), Vulvar Pain Functional Questionnaire (V-Q), Female Sexual Functioning Index (FSFI) and vaginal electromyography measurements. RESULTS: A total of 78 subjects, 39 in each group, completed the trial. Patients in Groups 1 and 2 received a mean of 46.9 and 48.4 TENS sessions. By day 120, there was a 38.2% reduction in the burning/pain and a 52.1% reduction in the dyspareunia VAS scores in Group 1, as compared to 21.3% (p = 0.003) and 23.1% in Group 2 (p = 0.01), respectively. FSFI, V-Q, and muscle-strength measures also improved but were not statistically significant. CONCLUSIONS: Our findings showed the potential of TENS in the treatment of VBD.

Does the addition of electrical stimulation or kinesiotherapy improve outcomes of amitriptyline treatment for women with vulvodynia? A randomized clinical trial.

INTRODUCTION AND HYPOTHESIS: Women diagnosed with provoked vulvodynia frequently report a great deal of frustration in achieving symptomatic relief. Physical therapy and drug treatment are among the interventions most indicated by guidelines; however, whether those modalities are effective when combined remains unclear. The objective was to evaluate the effectiveness of adding a physical therapy modality compared with amitriptyline alone for the treatment of vulvodynia. METHODS: Eighty-six women with vulvodynia were randomized to (G1) 25 mg amitriptyline, once a day (n=27), (G2) amitriptyline + electrical stimulation therapy (n=29) or (G3) amitriptyline + kinesiotherapy (n=30). All treatment modalities were administered for 8 weeks. The primary endpoint was the reduction in vestibular pain. Secondary measurements focused on sexual pain, frequency of vaginal intercourse, Friedrich score, and overall sexual function. Data were analyzed using intention-to-treat. RESULTS: All treatment modalities resulted in a significant decrease in vestibular pain (p<0.001), sexual pain (p<0.05), Friedrich score (p<0.001), and an increase in the frequency of sexual intercourse (p<0.05). G3 was more effective than G1 at reducing sexual pain (G1: 5.3±3.3 vs G3: 3.2±2.7; p=0.01) and at improving sexual function (G1: 18.8±9.8 vs G3: 23.9±7.8; p=0.04). CONCLUSION: Kinesiotherapy and electrotherapy additions to amitriptyline administration as well as amitriptyline alone, were effective at improving vestibular pain in women with vulvodynia. Women receiving physical therapy had the greatest improvement in sexual function and frequency of intercourse at post-treatment and follow-up.

Evaluation and Treatment of Vulvodynia: State of the Science.

Vulvodynia affects 7% of American women, yet clinicians often lack awareness of its presentation. It is underdiagnosed and often misdiagnosed as vaginitis. The etiology of vulvodynia remains unknown, making it difficult to identify or develop effective treatment methods. The purpose of this article is to (1) review the presentation and evaluation of vulvodynia, (2) review the research on vulvodynia treatments, and (3) aid the clinician in the selection of vulvodynia treatment methods. The level of evidence to support vulvodynia treatment varies from case series to randomized controlled trials (RCTs). Oral desipramine with 5% lidocaine cream, intravaginal diazepam tablets with intravaginal transcutaneous electric nerve stimulation (TENS), botulinum toxin type A 50 units, enoxaparin sodium subcutaneous injections, intravaginal TENS (as a single therapy), multimodal physical therapy, overnight 5% lidocaine ointment, and acupuncture had the highest level of evidence with at least one RCT or comparative effectiveness trial. Pre to posttest reduction in vulvar pain and/or dyspareunia in non-RCT studies included studies of gabapentin cream, amitriptyline cream, amitriptyline with baclofen cream, up to 6 weeks' oral itraconazole therapy, multimodal physical therapy, vaginal dilators, electromyography biofeedback, hypnotherapy, cognitive behavioral therapy, cold knife vestibulectomy, and laser therapy. There is a lack of rigorous RCTs with large sample sizes for the treatment of vulvodynia, rendering it difficult to determine efficacy of most treatment methods. Clinicians will be guided in the selection of best treatments for vulvodynia that have the highest level of evidence and are least invasive.

Women's Experience of Living with Vulvodynia Pain: Why They Participated in a Randomized Controlled Trial of Acupuncture.

Introduction: Vulvodynia is vulvar pain lasting at least 3-months without clear identifiable cause that may have other associated factors. The aim, to explore motivations of women participating in a double-blind randomized controlled trial of acupuncture for vulvodynia. Methods: Responses to the question: "Tell me about why you decided to participate in this study" were analyzed using conceptual content analysis to identify patterns in motivation for study participation. Results: Four patterns emerged: 1) desire to address uncontrolled pain, 2) desire for understanding, 3) wish to contribute to knowledge generation, and 4) need to remove cost barriers. Conclusion: Motivations indicate vulvodynia-specific aspects of acceptability of acupuncture. Clinical Trial Registration: NCT03364127.

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. Engström AH, Bohm-Starke N, Kullinger M, et al.

Treatment of Localized Vulvar Pain with Neural Therapy: A Case Series and Literature Review.

BACKGROUND: Localized vulvar pain (LVP) is a common condition among fertile women, with physical and psychosexual implications. Treatment is complex with limited benefits. Neural therapy is a regulatory therapy that uses injections of local anesthetics in low concentrations in specific points to treat different conditions. CASE PRESENTATION: We present the cases of 5 women, ages 33-44 years, with LVP treated with procaine 0.5% injections in painful points. Complete relief from pain occurred in 2 patients, and significant improvement in 3. Only 1 or 2 sessions were required. Initial VAS score was ≥70 and decreased to ≤30 after the intervention. The improvement was maintained over time, with a minimum follow-up period of 6 months. None of the patients were able to have sex or use tampons due to pain, but they were able to resume after the intervention. CONCLUSIONS: In this case series, local injections of procaine showed a favorable outcome. Future randomized clinical trials could help elucidate the role of this intervention in LVP.

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.

Somatic Dysfunctions of Hip and Pelvis Overlooked in a Case of Vulvodynia.

Vulvodynia is chronic perineal pain in women. Repercussions of this disorder can have a negative effect on women's health and lifestyle. The origin is often multifactorial, including pelvic and lower extremity somatic dysfunctions. If left untreated, these somatic dysfunctions can directly alter ligamentous tension on the pelvic floor and surrounding regions, resulting in perineal pain. Management of vulvodynia must be individualized due to the multifactorial etiology and complicated structure and function of the pelvic floor muscles. The authors present a case of vulvodynia in which osteopathic manipulative treatment was an effective management technique.

Moderators of Improvement From Mindfulness-Based vs Traditional Cognitive Behavioral Therapy for the Treatment of Provoked Vestibulodynia.

BACKGROUND AND AIM: The goal was to evaluate the moderators of mindfulness-based cognitive therapy (MBCT) and cognitive behavioral therapy (CBT) to improve dyspareunia, reduce pain catastrophizing, and improve overall sexual function in women with provoked vestibulodynia (PVD). Both treatments effectively reduced self-reported pain, sexual dysfunction, and pain catastrophizing in women with PVD. METHODS: A total of 130 women with PVD were assigned to CBT or MBCT. OUTCOMES: Potential moderators included (i) PVD subtype (primary or secondary), (ii) baseline pain intensity, (iii) trait mindfulness, (iv) treatment credibility, (v) relationship duration, and (vi) age. Outcomes were pain intensity, sexual function, and pain catastrophizing at 4 time points: before and after treatment and 6- and 12-month follow-up. Moderation was tested using multilevel models, nesting 4 time points within participants. The interaction of the moderator, time effect, and treatment group was evaluated for significance, and a simple slope analysis of significant interactions was performed. RESULTS: Pain reduction across 4 time points was the greatest in women who were younger, in relationships of shorter duration, and with greater baseline pain. Treatment credibility moderated pain intensity outcomes (B = 0.305, P < .01) where those with higher treatment credibility ratings (for that particular treatment) improved more in MBCT than CBT. PVD subtype moderated pain catastrophizing (B = 3.150, P < .05). Those with primary PVD improved more in the CBT condition, whereas women with secondary PVD improved more in the MBCT condition. Relationship length moderated sexual function (B = 0.195, P < .01). Women in shorter relationships improved more with MBCT, whereas women in longer relationships improved more on sexual function with CBT. No other tested variables moderated outcomes differentially across both treatment conditions. CLINICAL IMPLICATIONS: Women who present with high credibility about mindfulness, in shorter relationships, and with secondary PVD might respond better to MBCT whereas those with primary PVD and longer relationships might respond better to CBT. STRENGTHS & LIMITATIONS: Clinical sample. Half the women who were not sexually active were omitted from analyses of sexual function. CONCLUSION: Overall, treatment credibility, relationship length, and PVD subtype were found to moderate improvements differently in MBCT and CBT. These findings may assist clinicians in individualizing psychological treatment for women with PVD.

Double-blinding of an acupuncture randomized controlled trial optimized with clinical translational science award resources.

BACKGROUND: Clinical trial articles often lack detailed descriptions of the methods used to randomize participants, conceal allocation, and blind subjects and investigators to group assignment. We describe our systematic approach to implement and measure blinding success in a double-blind phase 2 randomized controlled trial testing the efficacy of acupuncture for the treatment of vulvodynia. METHODS: Randomization stratified by vulvodynia subtype is managed by Research Electronic Data Capture software's randomization module adapted to achieve complete masking of group allocation. Subject and acupuncturist blinding assessments are conducted multiple times to identify possible correlates of unblinding. RESULTS: At present, 48 subjects have been randomized and completed the protocol resulting in 87 subject and 206 acupuncturist blinding assessments. DISCUSSION: Our approach to blinding and blinding assessment has the potential to improve our understanding of unblinding over time in the presence of possible clinical improvement.

Mindfulness and cognitive behavior therapy for provoked vestibulodynia: Mediators of treatment outcome and long-term effects.

OBJECTIVE: Provoked vestibulodynia (PVD) is a chronic vulvo-vaginal pain condition affecting 8% of premenopausal women. Cognitive-behavioral therapy (CBT) is effective in managing pain and associated sexual and psychological symptoms, and a recent study found group mindfulness-based cognitive therapy (MBCT) to be equivalent. Our goal was to examine the long-term outcomes of these treatments and to explore mediators of change. METHOD: Participants were 130 women diagnosed with PVD who had participated in a clinical trial comparing 8 weeks of group CBT to 8 weeks of group MBCT. Data were collected at pretreatment, posttreatment, and at 6- and 12-month follow-up periods. Outcomes focused on (a) pain with vaginal penetration, (b) pain elicited with a vulvalgesiometer, and (c) sex-related distress. Mediators of interest included pain acceptance (both pain willingness and activities engagement), self-compassion, self-criticism, mindfulness, decentering, and pain catastrophizing. RESULTS: All improvements in the 3 outcomes were retained at 12-month follow-up, with no group differences. Pain catastrophizing, decentering, and chronic pain acceptance (both scales) were mediators of improvement common to both MBCT and CBT. Changes in mindfulness, self-criticism, and self-compassion mediated improvements only in the MBCT group. CONCLUSIONS: Both MBCT and CBT are effective for improving symptoms in women with PVD when assessed 12 months later. The findings have implications for understanding common and potentially distinct pathways by which CBT and MBCT improve pain and sex-related distress in women with PVD.

Acupuncture Augmentation of Lidocaine for Provoked, Localized Vulvodynia: A Feasibility and Acceptability Study.

OBJECTIVE: The aim of the study was to assess the feasibility and acceptability of acupuncture's augmentation of lidocaine therapy in the treatment of provoked localized vulvodynia (PLV). MATERIALS AND METHODS: For 12 weeks, women with moderate to severe PLV were randomized to either 18 sessions of traditional acupuncture (TA) or non-TA (NTA). All participants applied lidocaine 5% cream 4 times daily to the vestibule. Feasibility was assessed by recruitment, enrollment, assessment completion, and blinding. Acceptability was assessed by study visit attendance and satisfaction. The primary outcome was change in tampon test scores from baseline to week 12 and follow-up at week 24. RESULTS: Nineteen women enrolled and 14 completed the study. Five withdrew because of lidocaine reaction (n = 2), inability to insert tampon (n = 1), starting a new medication (n = 1), or change in vulvar diagnosis (n = 1). Participants in both groups reported pain reduction for 12 weeks. There was no statistically significant difference between groups. Women in the TA group (n = 7) experienced less pain from baseline to 12 weeks (mean difference [MD] = 42.4 ± 19.4 and MD = 35.7 ± 17.8 at week 24). In the non-TA group (n = 7), women experienced a within-group MD of 28.7 ± 28.5 at 12 weeks and an MD of 36.7 ± 17.7. CONCLUSIONS: In this early-phase research, acupuncture augmentation of lidocaine was acceptable. The study procedures, with modifications, may be feasible for future investigation. Both acupuncture techniques showed a favorable effect; however, the contribution to pain relief is undetermined.

[Vulvodynia - Diagnostics and Management Strategies]. / Vulvodynie: Diagnostik und Management.

Vulvodynia - Diagnostics and Management Strategies Abstract. Vulvodynia is characterized by chronic, idiopathic vulvar pain lasting for at least three months. After exclusion of other, specific diseases associated with vulvar pain, which can be treated accordingly, realistic therapy goals for this chronic disease should be defined. The therapy concept is multimodal, interdisciplinary as well as individualized and includes the combination of general recommendations with physiotherapeutic and psychotherapeutic measures. Pharmacological therapy, which is indispensable, is carried out off-label and includes the topical and/or systemic use of various substances and substance combinations. Surgical measures may be regarded as a possible option, especially in women with therapy-resistant and provocable vulvodynia. Alternative therapy options such as acupuncture, hypnosis and transcutaneous electrical nerve stimulation are also worth investigating.

Vulvodynia, "A Really Great Torturer": A Mixed Methods Pilot Study Examining Pain Experiences and Drug/Non-drug Pain Relief Strategies.

BACKGROUND: Women with vulvodynia, a chronic pain condition, experience vulvar pain and dyspareunia. Few studies examine the range and combination of treatment strategies that women are actually using to reduce vulvodynia. AIM: To describe pain experiences and pain relief strategies of women with vulvodynia. METHODS: Convenience sample, 60 women with vulvodynia (median age 32.5 [interquartile range {IQR} 8.5] years; 50 white, 10 racial/ethnic minorities) completed PAINReportIt and reported use of drugs and alcohol and responded to open-ended questions. Univariate descriptive statistics and bivariate inferential tests were used to describe average pain intensity scores, alcohol use, smoking, number of pain relief strategies, and their associations. Women's open-ended responses about their pain experiences and drug and non-drug pain relief strategies (NDPRS) were analyzed for patterns. OUTCOMES: Our mixed methods analysis connected data from pain measures, prescribed treatments and self-reported behaviors with women's free responses. This enabled nuanced insights into women's vulvodynia pain experiences. RESULTS: Women's descriptions of their pain and suffering aligned with their reported severe pain and attempts to control their pain, with a median pain intensity of 6.7 (IQR 2.0) despite use of adjuvant drugs (median 2.0 [IQR 2.0]), and opioids (median 1.0 [IQR 2.0]). 36 women (60%) used alcohol to lessen their pain. 26 women (43%) listed combining analgesics and alcohol to relieve their pain. 30 women (50%) smoked cigarettes. 54 women (90%) used ≥1 NDPRS. The mean number of NDPRS used was 2.1 ± 1.3 (range 0-6). The 5 most common NDPRS from women's comments were herbal medicine (40%), acupuncture (27%), massage (22%), hypnosis (15%), and mental healthcare (13%). CLINICAL IMPLICATIONS: Severe pain in women with vulvodynia may be a clinical indicator of those at higher risk of combining prescription pain medications with alcohol, which are all central nervous system depressants and may potentiate overdose. STRENGTHS AND LIMITATIONS: This pilot study demonstrated that the mixed methods approach to help understand the complexity of vulvodynia was feasible. We identified data showing a reliance on a high-risk mix of prescriptions and alcohol to reduce vulvodynia pain and a high prevalence of cigarette smoking. However, as a pilot study, these results are considered preliminary; the sample may not be representative. Perhaps only women at the extreme end of the pain continuum participated, or women took the survey twice because identifiers were not collected. CONCLUSION: Despite attempts to reduce pain using multiple therapies, including alcohol, women's vulvodynia pain is severe and not controlled. Schlaeger JM, Pauls HA, Powell-Roach KL, et al.

A Comparison of Mindfulness-Based Cognitive Therapy Vs Cognitive Behavioral Therapy for the Treatment of Provoked Vestibulodynia in a Hospital Clinic Setting.

INTRODUCTION: Chronic and distressing genito-pelvic pain associated with vaginal penetration is most frequently due to provoked vestibulodynia (PVD). Cognitive behavioral therapy (CBT) significantly reduces genital pain intensity and improves psychological and sexual well-being. In general chronic pain populations, mindfulness-based approaches may be as effective for improving pain intensity as CBT. AIM: To compare mindfulness-based cognitive therapy (MBCT) with CBT in the treatment of PVD. METHODS: To ensure power of 0.95 to find medium effect size or larger in this longitudinal design, we enrolled 130 participants. Of these, 63 were assigned to CBT (mean age 31.2 years), and 67 to MBCT (mean age 33.7 years). Data from all participants who completed baseline measures were analyzed, with intent-to-treat analyses controlling for years since diagnosis. MAIN OUTCOME MEASURES: Our primary outcome was self-reported pain during vaginal penetration at immediate post-treatment and at 6 months' follow-up. Secondary endpoints included pain ratings with a vulvalgesiometer, pain catastrophizing, pain hypervigilance, pain acceptance, sexual function, and sexual distress. RESULTS: There was a significant interaction between group and time for self-reported pain, such that improvements with MBCT were greater than those with CBT. For all other endpoints, both groups led to similar significant improvements, and benefits were maintained at 6 months. CLINICAL IMPLICATIONS: Mindfulness is a promising approach to improving self-reported pain from vaginal penetration and is as effective as CBT for several psychological endpoints. STRENGTH & LIMITATIONS: A strength of the present study was the robust sample size (n = 130 women) who had received confirmed clinical diagnoses of PVD. CONCLUSION: The present study showed mindfulness to be as effective for most pain- and sexuality-related endpoints in the treatment of PVD. Brotto LA, Bergeron S, Zdaniuk B, et al.

Altered gray matter volume in sensorimotor and thalamic regions associated with pain in localized provoked vulvodynia: a voxel-based morphometry study.

Multimodal neuroimaging studies provide support for a role of alterations in sensory processing circuits and endogenous pain modulatory systems in provoked vestibulodynia (PVD). In this study, we tested the hypotheses that PVD compared with healthy controls (HCs) would demonstrate gray matter volume (GMV) alterations in regions associated with sensorimotor, corticothalamic, and basal ganglia circuits. We also tested the replicability of previously reported gray matter increases in basal ganglia and hippocampal volumes in PVD vs HCs. In addition, disease specificity of GMV alterations were examined by comparing PVD with another chronic pain disorder. Finally, we examine whether GMV alterations are correlated with symptom measures. Structural magnetic resonance imaging was obtained in 119 premenopausal women (45 PVD, 45 HCs, and 29 irritable bowel syndrome [IBS]). A voxel-based morphometry analysis was applied to determine group differences in the hypothesized regions of interest. Compared with HCs, PVD women exhibited greater GMV in the basal ganglia, hippocampus, and sensorimotor cortices. Compared to patients with IBS, women with PVD had greater GMV in the hippocampus, and sensorimotor network, but lower GMV in the thalamus and precentral gyrus. Regional GMV alterations were associated with patient reports of pain during intercourse and muscle tenderness. The current findings provide further evidence that GMV is increased in PVD compared with HCs in several regions of the sensorimotor network and the hippocampus in patients with PVD. In addition, GMV distinct alterations in the sensorimotor network were identified between 2 pelvic pain disorders, PVD compared with IBS.

Mindfulness-Based Group Cognitive Behavior Therapy for Provoked Localized Vulvodynia: A Randomized Controlled Trial.

OBJECTIVE: The aim of the study was to compare the effectiveness of mindfulness-based group cognitive behavior therapy (M-gCBT) versus education support group therapy for the pain and distress associated with provoked localized vulvodynia. MATERIALS AND METHODS: Participants were randomized to M-gCBT or education support group therapy. Mindfulness-based group cognitive behavior participants attended 8 weekly sessions. Education support group participants received 8 weeks of online education with 3 in-person group visits. Vaginal insertion pain (tampon test) was the primary outcome. Secondary outcomes (Generalized Anxiety Disorder 7, Beck's Depression Index, Female Sexual Distress Scale, Female Sexual Function Index, and Pain Catastrophizing) were administered before intervention and at the completion of the study period, 3 months, and 6 months. Sample size was based on the ideal number for group dynamics of 6 to 12 participants per group. RESULTS: Participants were enrolled from August 1, 2016, to January 30, 2017. Thirty-two participants were enrolled and 31 were randomized: 14 to M-gCBT and 17 to education support. Baseline characteristics did not differ significantly. Vaginal insertion pain decreased in both groups but was not statistically different between groups (difference of 1.23; 95% CI = -0.52 to 2.98). At 6 months, participants in the M-gCBT group showed statistically significant improvement in the Female Sexual Function Index, Generalized Anxiety Disorder 7, and Beck's Depression Index compared with the education support group. CONCLUSIONS: Mindfulness-based group cognitive behavior and education support group therapy are effective in reducing pain and distress. However, women in the M-gCBT program showed greater improvement in certain secondary outcomes, indicating that M-gCBT may offer some advantages in reducing distress associated with provoked localized vulvodynia.
