Dry Needling for Provoked Vestibulodynia

Provoked Vestibulodynia Clinical Trial

Official title: Dry Needling for Women With Provoked Vestibulodynia: A Feasibility and Acceptability Randomized Controlled Study

Status Recruiting

Clinical Trial Summary

This is a randomized and controlled study investigating the feasibility and acceptability of a dry needling treatment for women suffering from provoked vestibulodynia. Following their enrollment in the study, participants will undergo a gynecological examination for confirmation of their diagnoses of provoked vestibulodynia. Women diagnosed with provoked vestibulodynia will be randomized into the dry needling group or the sham-needle group. The dry needling group will receive 6 sessions of real dry needling for 6 consecutive weeks. The sham group will receive 6 sessions of sham needling for 6 consecutive weeks, using a validated sham-needle. Outcomes measures will be assessed at baseline and at post-treatment and will include: feasibility and acceptability variables, pain intensity and quality, pain during palpation and pressure pain threshold, psychosexual variables, perceived improvement and satisfaction after the treatment as well as pelvic floor muscle stiffness and function.

Clinical Trial Description

Up to 18% of reproductive-aged women experience chronic pain in the vulvar region during sexual intercourse. This chronic pain condition is called vulvodynia. The main subtype of this pain condition is provoked vestibulodynia (PVD), which is characterized by a sharp or burning pain at the vaginal opening when there is a pressure applied to the vulvar vestibule or attempting vaginal penetration. Women suffering from PVD suffer from sexual dysfunctions, psychological distress and worsened quality of life. The treatment options currently available are still quite limited and some women still experience pain despite undertaking all options available. We, therefore, proposed a randomized and controlled study to investigate the feasibility and acceptability of a dry needling treatment for women suffering from PVD. Women diagnosed with provoked vestibulodynia will be randomized into the dry needling group or the sham-needle group. Participants and evaluators will be blinded. The dry needling group will receive 6 sessions of real dry needling for 6 consecutive weeks. For the first three sessions, the dry needling/or sham techniques will be aimed at the muscles of the trunk, lower back, hips and SI joints. For the last 3 treatment sessions, the dry needling/or sham techniques will aimed at the pelvic floor muscles. The sham group will receive the same 6 sessions of sham needling for 6 consecutive weeks, using a validated sham-needle. Outcomes measures will be assessed at baseline and 2 weeks post-treatment and will include: feasibility (adherence to treatment, retention rates, adverse effects, recruitment rates and data on dry needling (needles, # of insertions, pain related) and acceptability variables. Secondary outcomes will include pain intensity during intercourse (numeric scale) and quality (McGill pain questionnaire), pain during palpation and pressure pain threshold (Pressure algometer), psychosexual variables (sexual distress and sexual function), change in pain catastrophizing, change in quality of life in domains associated with chronic pelvic pain (Pelvic Pain Impact questionnaire, severity of symptoms related to central sensitization), perceived improvement and satisfaction after the treatment as well as pelvic floor muscle stiffness (shearwave elastography and dynamometric speculum)and function (dynamometric speculum), blinding efficacy. ;
