ONSTIM: Occipital Nerve Stimulation for the Treatment of Intractable Migraine
Abstract
Background: Medically intractable chronic migraine (CM) is a disabling illness characterized by headache greater than 15 days per month.
Method: A multicenter, randomized, blinded, controlled feasibility study was conducted to obtain preliminary safety and efficacy data on occipital nerve stimulation (ONS) in CM. Eligible subjects received an occipital nerve block, and responsers were randomized to adjustable stimulation (AS), preset stimulation (PS) or medical management (MM) groups.
Conditions: Chronic Migraine Headache.
Primary outcome: A primary endpoint is not identified for this feasibility study..
Enrollment: 110 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 110 participants or records.
