45 V vs 60 V Pulsed Radiofrequency of the Cervical Dorsal Root Ganglion for Cervical Radicular Pain | NCT07744438

NCT07744438

Overview

NCT ID: NCT07744438
Lead Sponsor: Ankara Etlik City HospitalOTHER_GOV
Official Title: Does Higher Voltage Improve Outcomes in Cervical Radicular Pain? A Comparison of 45 V and 60 V Pulsed Radiofrequency of the Cervical Dorsal Root Ganglion
Brief Summary: This study aims to compare the clinical outcomes of 45 V and 60 V pulsed radiofrequency (PRF) applied to the cervical dorsal root ganglion (DRG) in patients with cervical radicular pain. Treatment efficacy will be evaluated using the Numerical Rating Scale (NRS) for pain intensity and the Neck Disability Index (NDI) for functional disability. Procedure-related adverse events will also be compared to assess the safety of both voltage settings.
