Provoked, Localized Vulvodynia Treatment With Acupuncture and Lidocaine Pilot Study
Acupuncture Augmentation of Lidocaine for the Treatment of Provoked, Localized vulvodynia-a Feasibility and Acceptability Pilot Study
Study Overview
Status
Intervention / Treatment
Detailed Description
This is a randomized, controlled, single-blinded, pilot trial to study the feasibility and acceptability of acupuncture and 5% lidocaine. Patients will be recruited from the patient population of the Oregon Health & Science University Vulvar Health Clinic. Thirty (30) patients with PLV will be enrolled as study participants into the study. Fifteen (15) will be allocated in the treatment (classical) acupuncture + 5% lidocaine group and fifteen (15) will be allocated in the control (non-classical) acupuncture + 5% lidocaine group via a computer generated randomization program to balance allocation based on four variables: pain intensity, smoking status, body mass index, and pain duration.
The acupuncturist will interview each patient and perform an exam of the pulse and tongue. A standardized acupuncture treatment will be assigned, and both groups will receive 18 acupuncture treatments that follow a standardized protocol on classical or non-classical acupuncture points, with or without mild electrical stimulation. All study participants will self-apply lidocaine cream to their genital region four times daily during the study.

Intervention / Treatment |
---|---|
Experimental: Classical Acupuncture + Lidocaine
Study participants will attend 18 classical acupuncture sessions, twice a week for Weeks 1-6, and once a week for Weeks 7-12.
A standardized acupuncture treatment will be assigned with classical acupuncture points and may or may not be stimulated with electroacupuncture.
Very thin needles (0.18mm) will be inserted into locations either on the front or the back of the body and may be placed near or far from the affected area based on up to three Traditional Chinese Medicine Diagnosis categories.
Study participants will also be asked to gently apply 5% lidocaine cream four times daily (breakfast, lunch, dinner, and before bed).
|
Very thin needles (0.18mm) will be inserted into locations either on the front or the back of the body and may be placed near or far from the affected area.
No needles will be inserted into the genital region.
Locations needled will be in classical acupuncture points.
On even-numbered visits, the needles may be electrically stimulated via an electro-acupuncture machine.
Needles will be retained for 30 minutes per study visit.
Acupuncture needles used are 0.18x30-40mm, manufactured by Dong Bae Corporation (DBC), Korea.
The electrical acupuncture device is Pantheon Research Electrical Stimulator 8c, United States.
Study participants will gently apply 5% lidocaine cream four times daily to vulvar area.

Active Comparator: Non-classical acupuncture + lidocaine
Study participants will attend 18 non-classical acupuncture sessions, twice a week for Weeks 1-6, and once a week for Weeks 7-12.
A standardized acupuncture treatment will be assigned with non-classical acupuncture points and may or may not be stimulated with electroacupuncture.
Very thin needles (0.18mm) will be inserted into locations either on the front or the back of the body and may be placed near or far from the affected area.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Tampon Test
Time Frame: Weeks 1 and 12 study period
|
Primary outcome variable will be to measure the change in the reported pain of the "Tampon Test" (mean at Week 1) to the reported pain of "Tampon Test" (mean of Week 12); Every week, study participants will be asked to fully insert and remove a tampon and rate the level of pain with insertion on a 10-point Visual Analog Scale (0 indicating no pain, 10 indication worst possible pain). |
Weeks 1 and 12 study period

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cotton Swab test
Time Frame: Weeks -4, -3, -2, -1, 0, 1, 12 or 13 and 24.
|
Secondary outcome variable will compare the "Cotton Swab Test" with a blinded assessor reported pain at three timepoints. 1) change in reported pain at (mean at Weeks -2, -1, 0, and 1) to the reported pain (mean at Weeks 12 and 13; 2) change in reported pain (means Weeks -2, -1, 0, and 1) to the reported pain (mean at Week 24); 3) change in reported pain (mean at Week 12) to (mean at Week 24). Vestibular tenderness will be assessed by light touch with a cotton swab by a blinded assessor to the study participant's: 1) vestibule (cotton swab test) at four defined points (1:00, 5:00, 7:00, and 11:00); 2) the perineum; 3) labia majora (2:00 and 8:00), and 4) labia minora (4:00 and 10:00). Tenderness at each location will be rated by the Study Participant on a 10-point scale (0 indicating no pain, 10 indicating worst possible pain). |
