Clinical Trial Summary

The objective of this study is to perform a randomized controlled trial among female patients with a diagnosis of pelvic floor hypertonus (extreme muscle tension) with associated pain, dysfunctional voiding, dyspareunia, and/ or obstructed defecation.


Description:

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:

1. 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.

2. 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.

Outcome

Type Measure Description Time frame Safety issue
Primary Improvement in Quality of Life 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). To be assessed 1 month post-treatment. No
Secondary Improvement in Hypertonic Pelvic Floor Muscles 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. To be assessed at baseline and the following post-treatment intervals: 1, 2, 3, and 6 months No
