Erector Spinae Plane Block Versus Trigger Point Injection for Chronic Thoracic Myofascial Pain

Chronic thoracic (mid‐back) pain can be difficult to treat, and there is limited evidenceto guide the use of injection therapies for pain arising from muscles and surroundingsoft tissues. Two commonly used treatments are trigger point injections (TPI) and erectorspinae plane (ESP) blocks, but no studies have directly compared their effectiveness forchronic thoracic myofascial pain. The purpose of this study is to compare pain relief,physical function, emotional well‐being, patient satisfaction, and safety followingtreatment with either an ESP block or TPI. Participants will be randomly assigned toreceive one of the two treatments. Researchers will follow participants for up to 12weeks after the procedure and collect information through questionnaires and painassessments.
