This observational study aims to determine whether electromyography and nerve conduction study findings can help predict the response to cervical dorsal root ganglion pulsed radiofrequency treatment in patients with chronic cervical radicular pain. Adults aged 18 to 75 years with unilateral cervical radicular pain who are already scheduled to receive pulsed radiofrequency treatment will undergo an electrophysiological evaluation before the procedure. Participants will be classified according to whether cervical radiculopathy is detected on electrophysiological testing. Pain intensity, neck-related disability, quality of life, and depressive symptoms will be assessed before treatment and at 3 weeks, 3 months, and 6 months after the procedure. Outcomes will be compared between participants with and without electrophysiological evidence of radiculopathy to evaluate whether these findings are associated with treatment success.

Inclusion Criteria:
Age between 18 and 75 years Presence of cervical disc herniation and/or spinal stenosis Unilateral cervical radicular pain radiating to the arm for at least 3 months, confirmed by clinical evaluation, physical examination, and radiological imaging Inadequate response to conservative treatments, including physical therapy, medical treatment, and/or epidural steroid injection

Primary outcome measure(s)
Change From Baseline in Pain Intensity Assessed by the Numeric Rating Scale — Baseline, 3 weeks, 3 months, and 6 months after cervical dorsal root ganglion pulsed radiofrequency treatment Pain intensity will be assessed using an 11-point Numeric Rating Scale ranging from 0, indicating no pain, to 10, indicating the worst imaginable pain. Change from baseline will be calculated at each follow-up visit and compared between participants with and without electrophysiological evidence of cervical radiculopathy. A greater reduction in score indicates greater improvement in pain.
Treatment Success Based on the Numeric Rating Scale — 3 weeks, 3 months, and 6 months after cervical dorsal root ganglion pulsed radiofrequency treatment Treatment success is defined as a reduction of at least 50% in the Numeric Rating Scale pain score compared with baseline. The proportion of participants achieving treatment success will be compared between participants with and without electrophysiological evidence of cervical radiculopathy.
