Active clinical trials for "Vulvodynia"

Provoked vestibulodynia, previously called vulvar vestibulitis syndrome, is clinically defined as chronic, unexplained, vulvar pain or discomfort confined to the vulvar vestibule in response to contact or pressure. In addition, many patients also have pain in response to non-sexual activities such as tampon insertion, gynecological examinations or physical pursuits such as bicycle riding; the severity of other vulvo-vaginal symptoms such as itching, burning and irritation varies. Once women with provoked vestibulodynia develop the syndrome, symptoms may last for months or years; as a result, provoked vestibulodynia has a profound effect on women's sexuality and psychological well-being. The diagnosis of provoked vestibulodynia is usually made by ascertaining if the patient fulfills modified Friedrich's criteria, consisting of 1) a history of vulvar pain, dyspareunia or pain with tampon insertion, 2) tenderness of the vestibule when being touched with a cotton-tip applicator and 3) no identifiable cause for the pain. The etiology of this condition remains unknown. Proposed causes include chronic inflammation, peripheral neuropathy, genetic, immunologic and hormonal factors, infectious, psychological disorders, sexual dysfunction or disturbance in the central nervous system. Because the cause of provoked vestibulodynia remains unknown, many different treatments have been described for this condition, including topical and intra-lesional corticosteroids, topical anesthetics such as lidocaine, topical estrogen, topical or oral antidepressants or anti-convulsants, biofeedback or physical therapy, surgical resection of the involved tissue (vestibulectomy) and a variety of complementary and alternative therapies. Low level laser therapy (LLLT) is an emerging medical technique in which exposure to low-level laser light or light emitting diodes might stimulate or inhibit cellular function, possibly leading to beneficial clinical effects. Clinical applications that show some potential of effectiveness include treating soft tissue injury, chronic pain, and wound healing. The usage of low level laser therapy was found effective in various pain syndromes, and has no side effects. Since inflammatory mechanisms have been proposed in the pathogenesis of provoked vestibulodynia, and as there is no effective therapy for this syndrome, the investigators intend to study whether low level laser therapy might be an effective therapy for provoked vestibulodynia.

The objectives of this pilot study are to demonstrate effectiveness of application of the Erchonia Laser (manufactured by Erchonia Corporation),a non-invasive, non-significant risk low level laser red diode light therapy device, in providing relief of pain symptoms in patients with provoked and non- provoked vulvar vestibulitis; to reduce the frequency of use of oral medications to manage pain symptoms; and to reduce the debilitating affect vulvar vestibulitis has on the patient's daily activities, relationships and emotional well-being.

The purpose of this study is to determine whether pregabalin is effective in the treatment of vulvodynia.

The purpose of this research study is to evaluate if the medication gabapentin lessens the vulvar pain some women experience.

This study aims to assess the pain on contact in provoked vestibulodynia, measured with Visual Analogic Scale at week 0/week 2/week 6/week 12 after applying a patch of capsaicin.

The feasibility and acceptability of a somatosensory rehabilitation program and an educational pain management program will be investigated in women with provoked vestibulodynia. Forty-four women will be randomized into the two groups. The secondary objective is to explore the effects of the somatosensory rehabilitation program compared to the pain management program. Each participant will receive 12 weekly sessions with a physiotherapist. The somatosensory rehabilitation program includes minimizing contact with the painful zone of the vulva and uses repeated tactile stimulation at a tolerated distance, proximal to the vulva. The pain management program includes teaching participants about vulvar hygiene, chronic pain mechanisms, relaxation techniques, and approaches to reduce skin irritations in painful regions. Participants in both groups will also receive advice on sexual function and steps toward resuming sexual activities with vaginal penetration. Feasibility and acceptability outcomes will be assessed and analyzed using descriptive statistics for the adherence rates to treatment sessions and home exercises, the recruitment rate, retention rate, satisfaction, and adverse effects. The results will be compared to predetermined thresholds to determine the feasibility and acceptability of a future clinical trial. Secondary measures will be assessed at baseline, two weeks after the treatment, and at three months follow-up. These outcomes will be assessed using validated questionnaires (pain, sexual function, global impression of change, psychological variables, quality of life) as well as evaluations of tactile and pressure sensitivity in vulvar regions using monofilaments, a 2-point aesthesiometer and an algometer. Linear mixed models for repeated measurements (2 groups, 3 measurement times) will be used to explore the treatment effects and will contribute to determining the feasibility of a future clinical trial. Hypothesis and expected results: It is expected that both programs will meet the pre-determined criteria for acceptability and feasibility in women with provoked vestibulodynia. This study will provide guidance for a future randomized clinical trial.

CO2 laser energy is currently used widely for the treatment of postmenopausal women who have vaginal atrophy due to the lack of estrogen. However, its effect on premenopausal women with hormonally-mediated vulvar vestibulodynia is unknown. This study seeks to evaluate the effect of CO2 laser on young women and compare it to topical lidocaine.

Provoked vestibulodynia is a pain condition, which is associated with lower quality of life and discomfort. Furthermore, it is underdiagnosed and undertreated. Provoked vestibulodynia is defined as vulvar pain with no known cause. Provoked vestibulodynia can be generalized and involve several areas of the vulva. It can also be localized and involve only one area of the vulva. Pain is often provoked by touch or pressure but it can also be spontaneous or both. The life prevalence for vestibulodynia varies between 3-28 percent in different populations. Persons with vestibulodynia report more frequently anxiety-, depression- and stress- symptoms than the normal population. The aim of the present study is to evaluate an internet-based treatment for vestibulodynia. The intervention will be based on Acceptance and commitment therapy (ACT) and cognitive behavior therapy with focus on exposure and acceptance.

Hypothesis: Specific physiotherapy interventions will decrease pain, improve pelvic floor motor control, increase self efficacy, improve sexual function and decrease pain catastrophizing behaviour in women with provoked vulvar vestibulodynia. This study will look at specific physiotherapy treatment interventions to see if they decrease pain, improve pelvic floor motor control, increase self efficacy, improve sexual function and decrease pain catastophizing behaviour. Participants will fill out a questionnaire on their pain symptoms and complete standardized scales prior to starting treatment and after 4 sessions to determine change due to interventions. A combination of physiotherapy, group educational sessions and group cognitive behavioural therapy will have better outcomes than physiotherapy alone. Results of physiotherapy intervention alone will be compared to results of those treated with physiotherapy, group educational sessions and group cognitive behavioural therapy at a separate treatment centre. Physiotherapy interventions and outcome measures are the same between both groups. Justification: Standard treatment is hard to identify as many approaches are taken, none with any evidence to support them. This study aims to look at specific techniques (pelvic floor coordination and relaxation exercises, education on female sexual response and pain pathophysiology education) to see if there is a benefit.

The current pilot study aims to assess the feasibility and preliminary efficacy of a novel, 12-week targeted couple intervention (CBCT) for women with vulvodynia and their partners.
