Brief Summary
This study evaluates a novel treatment approach for medication overuse headache (MOH) using greater occipital nerve pulsed radiofrequency (GONPRF). Three treatment strategies are compared: Standard Treatment: Limitation of overused acute headache medications, lifestyle counseling, and continuation of existing preventive medications. Primary GONPRF: GONPRF administered in addition to standard treatment. Modified GONPRF: GONPRF administered as a second-line intervention in individuals who do not respond adequately to standard treatment alone. The study assesses whether GONPRF, when applied early or after an initial period of standard care, reduces monthly headache days more rapidly and effectively than standard treatment alone. Outcomes are evaluated over a 6-month follow-up period using headache diaries and scheduled clinical assessments. This is a randomized controlled trial designed to systematically evaluate the clinical benefit of GONPRF in patients with medication overuse headache.

Outcome Measures
Primary Outcomes (1)
Change in Monthly Headache Days
Number of headache days per month, defined as days with headache lasting ≥4 hours and/or requiring acute headache treatment, recorded using patient headache diaries. The primary analysis compares the change from baseline to 3 months.
Baseline to 3 months
Secondary Outcomes (7)
Monthly Headache Days - 1 and 6 Months
Baseline, 1 month, and 6 months
Monthly Acute Medication Use Days
Baseline, 1 month, 3 months, and 6 months
Headache Pain Intensity (Numeric Rating Scale, NRS)
Baseline, 1 month, 3 months, and 6 months
Headache Duration (hours)
Baseline, 1 month, 3 months, and 6 months
Headache Impact Test-6 (HIT-6) Score
Baseline, 1 month, 3 months, and 6 months
- +2 more secondary outcomes
Other Outcomes (2)
GONPRF Treatment Side (Unilateral/Bilateral)
During the GONPRF procedure (Day 1 of intervention)
Adverse Events Related to GONPRF
From the time of the GONPRF procedure through study completion (up to 6 months).
Study Arms (3)
Arm 1- Standard Treatment (Group A1)
EXPERIMENTALIntervention Name: Standard Care Intervention Type: Other (Behavioral / Educational / Non-drug) Description: Limitation of overused acute headache medications, lifestyle advice (nutrition, hydration, activity, sleep), and continuation of preventive medications. Participants who respond at 1 month continue standard care.
Arm 2: Primary GONPRF (Group B)
EXPERIMENTALIntervention Name: Greater Occipital Nerve Pulsed Radiofrequency (GONPRF) Intervention Type: Procedure Description: GONPRF applied at C2 under ultrasound guidance in addition to standard care, starting at enrollment. Follow-up at 1, 3, and 6 months.
Arm 3: Modified GONPRF (Group A2)
EXPERIMENTALIntervention Name: Greater Occipital Nerve Pulsed Radiofrequency (GONPRF) - Second Line Intervention Type: Procedure Description: Participants initially on standard care who do not achieve ≥50% improvement at 1 month receive GONPRF as a second-line intervention, alongside continued standard care, with follow-up at 3 and 6 months.
Interventions
Limitation of overused acute headache medications, lifestyle advice (nutrition, hydration, activity, sleep), and continuation of preventive medications. Participants who respond at 1 month continue standard care.
GONPRF applied at C2 under ultrasound guidance in addition to standard care, starting at enrollment. Follow-up at 1, 3, and 6 months.
