Brief Summary:

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 em
