Ultrasound Guided Transversus Abdominis Plane (TAP) vs. Trigger Point Injection (TPI) for Abdominal Wall Pain

Completed · Phase 2

Conditions studied: Abdominal Pain

In brief

Patients with chronic abdominal pain- with a component of abdominal wall pain- are often treated with trigger point injections. This study will help to determine if a block within the transversus abdominis plane (TAP) will provide superior analgesic benefit to a trigger point injection as therapy for these patients.
