A Study Examining the Use of Vaginal Nifedipine With Pelvic Floor Physical Therapy for Levator Myalgia and Pelvic Pain
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
|Official Title:||Does Adjunctive Treatment With Vaginal Nifedipine Result in Symptomatic Improvement in Patients With Levator Myalgia and Pelvic Floor Pain Who Are Undergoing Pelvic Floor Physical Therapy?|
- Improvement in Quality of Life [ Time Frame: To be assessed 1 month post-treatment. ]The primary outcome will measure quality of life metrics, as reported by the patient herself. We will use the following validated instruments: Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire, and validated 11-point pain scale. The aim is to measure whether the patient experienced improvement in her symptoms when vaginal nifedipine was administered (in addition to physical therapy).
- Improvement in Hypertonic Pelvic Floor Muscles [ Time Frame: To be assessed at baseline and the following post-treatment intervals: 1, 2, 3, and 6 months ]The secondary outcome measure will be assessed and reported by the healthcare provider at the above visits. After instructing the patient to voluntarily relax the pelvic floor muscles, the resting tone will be measured using the Oxford scale, which is a validated digital assessment.

|Estimated Primary Completion Date:||May 2014 (Final data collection date for primary outcome measure)|
Placebo Comparator: Ointment Base
Patients in this arm will serve as the control and will undergo pelvic floor physical therapy and receive placebo (lanolin and mineral oil base).
Drug: Placebo Ointment Base
Placebo administered twice per day for 28 days; as a vaginal ointment applied to vulvar and vaginal area
Active Comparator: Nifedipine Ointment
Patients in this arm will undergo pelvic floor physical therapy, but will receive compounded vaginal nifedipine.
Nifedipine - 0.2% concentration in a lanolin base; administered twice per day for 28 days; as a vaginal ointment applied to vulvar and vaginal area
Given the paucity of information and the magnitude of debilitation that can be associated with chronic pain syndromes, the potential to ameliorate pain and successfully treat these symptoms is an area that merits further exploration. In this study, we hypothesize that the addition of vaginal nifedipine to a physical therapy protocol will result in greater treatment success than treatment with physical therapy alone.
The objective is to perform a randomized controlled trial among female participants with a diagnosis of pelvic floor hypertonus with associated pain, dysfunctional voiding, dyspareunia, and/or obstructed defecation. Group 1 will serve as the control and will undergo pelvic floor physical therapy and placebo (lanolin and mineral oil base). Group 2 will also undergo pelvic floor physical therapy, but will receive compounded vaginal nifedipine.
Specific aims include:
- Comparison of subjective outcome measures, specifically quality of life metrics scales: Pelvic Floor Distress Inventory, Pelvic Floor Impact Questionnaire, and validated 11-point pain scale.
- Comparison of objective outcome measures, specifically a validated digital assessment of pelvic floor strength: the Oxford scale.
Group 1 will serve as the control and will undergo pelvic floor physical therapy and placebo (lanolin base). Group 2 will also undergo pelvic floor physical therapy, but will receive compounded vaginal nifedipine. We will collect data on these patients to determine if the treatment of vaginal nifedipine with physical therapy provides a more successful treatment for this pelvic floor dysfunction.
