|Condition or disease||Intervention/treatment||Phase|
|Vulvar Vestibulitis Vestibulodynia||Device: Cold laser||Not Applicable|
In the current proposed pilot study, application of a low level laser light device, manufactured by Erchonia Corporation, to reduce the pain of vulvar vestibulitis will be evaluated. The Erchonia Laser device will emit three independent 7 milliWatt, 635 nanometer red light diodes in a hand-held device and is a variable frequency pulsed wave device.
Erchonia low level lasers have been determined safe and effective and non-significant risk (NSR) by the Food and Drug Administration (FDA) for application for numerous and various pain reduction indications, providing justification for the anticipated safety and effectiveness of application of the Erchonia Laser to reduce pain in patients with vulvar vestibulitis. The FDA has granted 510(k) clearances for Erchonia low level laser devices for five pain reduction indications, all cleared under Product Code 'NHN', defined as: "A light based non-laser device that emits energy in infrared or other wavelengths, provides non-heating and non-thermal effect, and is indicated for adjunctive use in pain therapy or related indication. It does not provide therapeutic topical heating."
The research will be conducted at ProHealth Care; Inc. across four campuses. Patients will be seen in private rooms in the therapy departments.
All study staff are licensed in the field of either Occupational Therapy or Physical therapy (2 in each) with the advanced continuing education necessary to call them a "specialist" in the treatment of pelvic floor disorders. All investigators will complete CITI training for research.
Subjects will be referred into the ProHealth Care system via a prescription for pelvic floor therapy signed by a licensed medical professional with the expertise to diagnose Vulvar vestibulitis. Written information regarding the study and proposed treatment will also be mailed to a larger group of pelvic floor therapists in the greater Milwaukee Wisconsin region through a "Pelvic Floor Study Group" list informing them of the need for subjects with this diagnosis so that they may inform their clients of the availability of such research. These clients may then request a referral from their private health care provider.
The pilot study will be completed in twelve months following the commitment of ProHealth Care, Inc. Institutional Review Board as well as procurement of initial funding through grants applied for during 2013. There will be 10 patients enrolled in the pilot study.
Patients will be screened after they are referred by their physician for physical therapy.

Experimental: Cold Laser Treatment
Cold laser used off of the body over the vulvar involved area. The device to be used in this study is the Erchonia Corporation variable frequency pulsed wave low level laser device employing three independent 7 milliWatt, 635 nanometer red light diodes mounted in a hand-held device and is a variable frequency pulsed wave device. Weekly visits x 6 with 5 minute treatments over vulva and sacral nerve roots each.

- Percent Improvement Change in Visual Analogue Pain Scale (VAS) Calculated With Q-tip Palpation Over 6 Sites From Baseline Visit to Follow up at Two Week From Last Visit [ Time Frame: Average of all sites Compared from baseline visit and at 8 week (from start) follow up ]
III. Q-tip testing:
. Q-tip pressure will be applied at the following areas, in the exact order listed: 2:00, 10:00, 5:00, 7:00, 12:00, and 6:00. An average VAS report of pain taken overall and compared from first baseline visit to end of study re-assessment two weeks following last treatment.
• Pain intensity marked an a line with a point between 0-100 on the Visual Analogue Scale (VAS). A separate rating is recorded for each of the 6 numbered areas (see box 1 for reference). 100 is maximum pain level and 0 is no pain measured in centimeters per FDA guidelines for pain calculation on the VAS
- Change in Patient Specific Functional Scale Questionnaire [ Time Frame: Baseline, and two weeks following last treatment at Week 8 ]Questionnaire that measures on a 0-10 scale (0= No function, and 10= normal function) one function that most impacts the patient's present symptoms (vaginal penetration/intercourse chosen as most important and pertinent) Measured amount of point change on the scale.
- Change in the Vulvar Pain Functional Scale Questionnaire [ Time Frame: Baseline, and after last treatment visit at Week 8 ]
Questionnaire of eleven questions involving specific functions that may impart pain in the vulvar region and patient response to present tolerance level. Questions have 4-5 answer choices weighted on a 0-3 scale of impairment, with 3 being worst.
Worst reported score of functional impact =33. No functional impact = 0
