Eredeti leírás

Migraine is among the leading causes of disability worldwide. Inappropriate use of acute medications in the setting of primary headache, particularly migraine can result in a debilitating condition known as medication overuse headache (MOH). Treatment of MOH is challenging and the primary therapeutic approach is reducing painkillers which helps decrease the number of headache days. As a part of the detoxification process to discontinue acute medications, bridging therapy is often needed to reduce withdrawal headache. Currently, there are data supporting the use of greater occipital nerve block as a preventive treatment in chronic migraine, but no placebo-controlled trial has evaluated the efficacy of greater occipital nerve block in MOH. Therefore, this research aims to demonstrate the efficacy of greater occipital nerve block in detoxification of migraine patients with MOH. Patients will be recruited from Headache Clinic at 3 centers in Thailand from February 2026 to January 2028. After recruitment, patients will be randomized into 2 groups at a 1:1 ratio using a block of four, namely group A and B. A 5-mL syringe of 2 mL of lidocaine 2% and 2 mL of methylprednisolone 40 mg/mL (80 mg) will be prepared for each patient in group while a 5-mL syringe of 4 mL normal saline will be prepared for each patient in group B. Monthly headache days, duration, severity, acute medication type and number of usage days and relative headache status according to a 5-point Likert scale will be investigated at the 2 weeks, 1st, 2nd and 3rd month, MIDAS at the end of 3rd month.A teljes eredeti leírásKevesebb
