Transvaginal Electrical Stimulation for Myofascial Pelvic Pain

Myofascial Pelvic Pain (MPP) is a frequently overlooked musculoskeletal cause of chronic pelvic pain affecting 10-20% of all adult women. Despite high prevalence and societal costs, few effective treatments exist and are difficult to access due to shortages of skilled personnel. Treatments for MPP using electrical stimulation to induce muscle fatigue have proven efficacy at reducing pain, improving circulation, and promoting tissue healing, but have proven difficult to implement in gynecologic practice. The aim of this three-arm randomized study is to evaluate the utility of transvaginal electrical stimulation at a fixed frequency of 200 Hz in women with symptomatic MPP in comparison to the standard, first-line treatment with education, stretching, and low-impact exercise. Nursing staff without prior training will be taught to deliver this high-frequency transvaginal electrical stimulation (HF-TES) treatment using the device. Responses to treatment provided by a specialist physician and licensed vocational nurse will be compared. Patients with \>50% pain improvement will determine the effectiveness of HF-TES. Responses to treatment provided by a specialist physician and licensed vocational nurse will also be compared. Participants will be followed for 3 months following treatment completion.

NIRS for the Diagnosis of Myofascial Pelvic Pain

Myofascial Pelvic Pain (MPP) is an often-misdiagnosed condition affecting up to 26% of women during their lives and imposing enormous costs on national health care systems. It frequently involves comorbidities such as bladder, bowel, and sexual dysfunction. There are no quantitative measures that adequately guide the physician and accurate diagnosis typically requires an internal examination by a tertiary specialist. This study will develop and test an instrument to establish a normal range for near infrared spectroscopy (NIRS) optical changes associate with pelvic floor exercise in adult women based on the test-to test (intra-day) reliability of oxygen kinetics related to contraction of the pelvic floor muscle. We will establish the relationship between the quantitative NIRS data, the condition of Myofascial pelvic musculature and the symptomatology of MPP and related comorbidities. We will also evaluate prospectively the effectiveness of these data in predicting effective treatment modalities. Finally, we will optimize a training regime for non-specialists to allow this technique to be used in a variety of settings. The development of this device and validation of its relevance to diagnosis and treatment of MPP will provide effective care sooner and at a lower cost than current procedures. It will also reduce inequities in the availability of care to underserved populations by providing an inexpensive, reliable and easily available method for a variety of providers to address MPP.
