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
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.
• Unilateral cervical radicular pain consistent with cervical disc herniation.
• Pain intensity of ≥6 on the Numerical Rating Scale (NRS).
• Radicular pain persisting for at least 3 months.
• MRI evidence of lower cervical nerve root compression consistent with clinical findings.
• Inadequate response to conservative treatment, including analgesic medications and physical therapy.
• Completion of cervical dorsal root ganglion pulsed radiofrequency (PRF) treatment.
