ID: 205115 Comparison of Pain Relief and Radiographic Multifidus Changes With Radiofrequency Ablation Versus Peripheral Nerve Stimulation

Abstract

Multifidus muscle (MM) atrophy is present in nearly 80% of patients with chronic low back pain (CLBP). Functionally, the multifidi work as postural muscles and are difficult to strengthen in this context. The relative size of the MM also relates to the ratio of crucial core muscles and is significant as it predicts injury in athletes. Radiofrequency ablation (RFA) of the medial branch nerves has become common practice in the treatment of CLBP despite its neuro-destructive effects, with statistically significant atrophy exhibited 24 weeks post-procedure when compared to controls. No studies have sought to compare the effects of RFA or temporary PNS of the medial branch nerves on pain scores and the size of multifidus muscle when used for the same clinical diagnoses.
