Arm Description
Intervention is a one time 30 cc intravaginal injection totaling a dose of 200u of onabotulinumtoxin A and saline injected throughout the pelvic floor at 1, 3, 5, 7, 9 and 11 o'clock sites/locations. An injection of 30 cc of ropivicaine (5cc/6 sites) will be used, followed by a mixture of 200 u of Onabotulinumtoxin A and 6 cc of saline (1cc/injection site).
Intervention is a one time 30 cc intravaginal injection totaling a dose of 40mg/cc of Kenalog (triamcinolone) and ropivicaine 0.5% (29cc) injected throughout the pelvic floor at 1, 3, 5, 7, 9 and 11 o'clock sites/locations. A mixture of 40mg/1 cc of triamcinolone (40 mg) and 29cc of ropivicaine 0.5% (5cc/6 sites) will be used, followed by 6 cc of saline (1cc/injection site).
Outcomes
Primary Outcome Measures
Pain Assessed by Change in Overall Pain Score Using the Visual Analog Scale (VAS).
The visual analog scale asks subjects to rate their level of pain on a scale from 0-10, with 0 being 'No pain' and 10 being 'Worst pain imaginable', hence lower scores are better. The baseline and follow-up visual analog scale for pain was obtained at every visit regardless if the patient received Trigger Point Injections. The difference between visual analog scale at 1 month and the visual analog scale at baseline was calculated. Positive numbers indicate the pain increased from baseline to 1 month and negative numbers indicates that pain decreased.
Pain Severity Assessed by Change in Overall Pain and Other Related Scores Using Questions 3, 4, 5, and 6 in the Brief Pain Inventory (BPI) Questionnaire.
Pain severity was constructed by averaging questions 3,4,5 and 6 of the brief pain inventory questionnaire (adding scores together and dividing by 4). Each question is on a scale from 0 (no pain) to 10 (pain as bad as you can imagine). Thus, lower numbers represent a better outcome. The difference between pain severity at 1 month and the pain severity at baseline was calculated. Positive numbers indicate the pain severity increased from baseline to 1 month and negative numbers indicates that the severity of the pain decreased.
Pain Interference Assessed by Change in Overall Pain and Other Related Scores Using Questions 9A Through 9G in the Brief Pain Inventory (BPI) Questionnaire.
The Pain Interference score was constructed by averaging the individual interference question scores from the brief pain inventory questionnaire (adding scores from questions 9A-9G and dividing by 7). The questions assess how, during the past 24 hours, pain has interfered with general anxiety (9A), mood (9B), walking ability (9C), normal work (9D), relations with other people (9E), sleep (9F), and enjoyment of life (9G). Each question is scored on a scale from 0 (does not interfere) to 10 (completely interferes). Thus, a lower value represents a better outcome. The difference between pain interference at 1 month and the pain interference at baseline was calculated. Positive numbers indicate the pain severity increased from baseline to 1 month and negative numbers indicates that the severity of the pain decreased.
Pain Assessed by Change in Overall Pain Symptom Using Question 2 of the Global Response Assessment (GRA) Questionnaire.
The GRA questionnaire asks subjects to rate symptoms and functioning since having the research procedure, Trigger Point Injections (TPI). Question 2 asks the subject to rate their pain symptoms since having TPI. Scores are on a Likert scale, ranging from 1 (Markedly Worse) to 7 (Markedly Improved).
Secondary Outcome Measures
Pain Assessed by Change in Overall Pain Score Using the Visual Analog Scale (VAS) Questionnaire.
The visual analog scale asks subjects to rate their level of pain on a scale from 0-10, with 0 being 'No pain' and 10 being 'Worst pain imaginable', hence lower scores are better. The baseline and follow-up visual analog scale for pain was obtained at every visit regardless if the patient received Trigger Point Injections. The difference between visual analog scale at 3 months and the visual analog scale at baseline was calculated. Positive numbers indicate the pain severity increased from baseline to 3 months and negative numbers indicates that the severity of the pain decreased.

Pain Assessed by Change in Overall Pain Score Using the Visual Analog Scale (VAS) Questionnaire.
The pain visual analog scale (VAS) is a tool used by the patient to describe their pain intensity. Utilizing the VAS, the patient describes their pain at baseline, before receiving trigger point injections. The VAS ranges from 0 (no pain) to 10 (worst possible pain). Thus, a lower value represents a better outcome.
Pain Severity Assessed by Change in Overall Pain and Other Related Scores Using Questions 3, 4, 5, and 6 in the Brief Pain Inventory (BPI) Questionnaire.
Pain severity was constructed by averaging questions 3,4,5 and 6 of the brief pain inventory questionnaire (adding scores together and dividing by 4). Each question is on a scale from 0 (no pain) to 10 (pain as bad as you can imagine). Thus, lower numbers represent a better outcome. The difference between pain severity at 6 months and the pain severity at baseline was calculated. Positive numbers indicate the pain severity increased from baseline to 6 months and negative numbers indicates that the severity of the pain decreased.

5. Study Description
Brief Summary
The goal of this study is to compare the effectiveness of two different medications used in intravaginal trigger point injections (injections into extremely painful areas of a muscle) to treat chronic pelvic pain. The study compares onabotulinumtoxinA (BOTOX®) (a drug prepared from the bacterial toxin botulin which temporarily paralyzes muscles) to Kenalog (a synthetic corticosteroid used as an anti-inflammatory agent).
Detailed Description
Chronic pelvic pain (CPP) is a common and often debilitating problem among women. The musculoskeletal system is an important factor in chronic pelvic pain. Studies have demonstrated that women with CPP had more frequent musculoskeletal findings. On physical examination, myofascial trigger points have been found. Trigger points are hyperirritable bands of muscle that can be felt from the vaginal wall. They are often knot-like or taut and are painful when pressure is placed on them. Intravaginal injections of these trigger points using steroids including Kenalog (triamcinolone) have been done and produced decreases in pelvic pain. Trigger point injections of Onabotulinumtoxin A has also been shown to decrease pain in subjects with CPP. This study will compare these two drugs and assess pain (using subject questionnaires) at one, three and six months post injection.
