Ultrasound and EMG Guided Botox Injection for the Treatment of Non-Relaxing Puborectalis Syndrome

Summary

Our study aims to determine the efficacy of ultrasound and EMG guided Botox injections into the puborectalis muscle in women with non-relaxing puborectalis syndrome. With use of this technique, we believe we will find that Botox injections decrease symptom severity and improve quality of life (QOL) in patients with NRPS. All enrolled patients will receive ultrasound and EMG guided Botox injections at three points along the puborectalis muscle. Post-injection data will be obtained with a defecation diary and questionnaire data at the 2-week, 3-month, and 6-month intervals.
