Primary Outcome Measures:
  • Surface EMG [ Time Frame: After 28 days of treatment ]
    A baseline sEMG will be compared to sEMG after 28 days of treatment.

Secondary Outcome Measures:
  • Surface EMG Midpoint [ Time Frame: 14 days after treatment ]
    A baseline sEMG will be compared to sEMG after 14 days of treatment.

  • FSFI [ Time Frame: 28 days ]
    Baseline FSFI scores will be compared to scores after 4 weeks of treatment to asses sexual function

  • VAS [ Time Frame: 28 days ]
    Visual analog scale for pain will be collected at baseline and compared to VAS after 28 days of treatment

  • SF-12 [ Time Frame: 28 days ]
    baseline SF-12 scores will be compared to SF-12 scores after 28 days of treatment to asses quality of life in the two domains of mental and physical well-being.

  • PGI-I [ Time Frame: 28 days ]
    Patient Global Impression of Improvement will be asked after 28 days of treatment to determine if the patient felt the treatment was helpful

  • PGI-S [ Time Frame: 28 days ]
    Patient Global Impression of Severity will be collected and compared to determine how severe teh patient perceived their condition to be before and after treatment

Detailed Description:
High tone pelvic floor dysfunction is a common cause of pelvic pain in females. It is thought to be initiated by a sentinel event such as trauma, surgery, or vaginal delivery1. Currently, treatment options include warm baths, stretching, physical therapy with myofascial therapy or biofeedback, or pharmacologic therapy with oral amitriptyline or tiazadine2. Physical therapy can be effective. However, it usually involves frequent visits to a specialized physical therapist to undergo intravaginal treatments consisting of myofascial release, massage, or biofeedback. We would like to find a treatment option for patients that would be effective without the invasive and time consuming nature of physical therapy. It is known that diazepam is a valid treatment option for disorders involving spasticity including spastic cerebral palsy5 and tetanus. A literature search on diazepam and high tone pelvic floor dysfunction revealed one paper. This study has an intrinsic flaw as it is a retrospective chart review, and the results are confounded by concurrent physical therapy. They were, however, able to find that patients treated with diazepam suppositories showed a significant improvement in pelvic floor tone. They also assessed pain and sexual function, but these did not reach statistical significance.
