Comparison of the Efficacy of Ultrasound-guided Greater Occipital Nerve Block and Pulsed Radiofrequency Therapy in Chronic Migraine Patients

Plain-language summary
Chronic migraine (CM) is related to headache-related disability and reduced quality of life. Therefore, patients with CM require preventive treatment. The aim of this double-blind, comparative-effectiveness study was to compare ultrasound-guided great occipital nerve (GON) block and pulsed radiofrequency (PRF) application in CM patients.
The study consisted of 2 groups: GON block (group GONB) and GON block + pulsed RF (group GONB+PRF). Each group had 16 patients. Ultrasound-guided GONB was performed to locate the nerve more accurately. With 0.5 Hz sensorial stimulation, a 5-cm-long radiofrequency needle was advanced under ultrasound guidance in both groups. GON block was performed in all patients by administering 5mg bupivacaine through a PRF needle. After the GON block, the PRF neuromodulation was applied at 42 degrees for 4 minutes in the GONB-PRF group. In the GONB group, no pulse was given. The patients were examined for follow-ups at the 1st, 2nd, 3rd, and 6th months after the procedure. The severity and the number of migraine attacks, and the number of analgesic drugs were noted.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
