Preventive pharmacologic therapies for migraine aim to reduce attack frequency and duration and improve quality of life; however, their use, overall benefit and adherence are often limited. Remote electrical neuromodulation (REN) is a non-invasive FDA-cleared wearable device for acute and/or preventive migraine treatment. This study will evaluate the real-world efficacy and patient-reported outcomes of preventive REN use over 3 months in migraine patients.
