About this trial
Chronic vulvar pain is a highly prevalent and debilitating condition affecting up to 16% of women. The most common subtype of vulvar pain, provoked vestibulodynia (PVD), is characterized by a sharp pain at the entry of the vagina in response to pressure or attempted vaginal penetration. Women with PVD not only present with psychological distress and significant disruption in all aspects of sexual function, but they are also confronted with limited effective treatment options. Dry needling (DN) could fill this therapeutic gap. Similar to acupuncture, this approach involves the insertion of fine needles into the tissues. However, its mechanisms of action are quite different. DN specifically targets muscle tension/stiffness, which has been shown to play a key role in PVD. After designing a DN treatment protocol tailored to the affected muscles in PVD, our randomized pilot study confirmed that our state-of-the-art DN treatment protocol is feasible and acceptable for treating PVD and the promising findings obtained provide support for conducting the proposed large-scale study.
The proposed multicenter randomized controlled trial aims to establish the efficacy of DN for reducing pain in women with PVD. Women will be randomized to receive either sham or real DN for 8 weekly sessions. Validated outcome measures will be assessed at baseline, post-treatment and at the 6-month follow-up.
The current proposal addresses the urgent need to develop novel treatment options for women with PVD. If proven effective, DN could be proposed as a first-line low-risk treatment.
