Biofeedback-VR for Treatment of Chronic Migraine

Chronic migraine (CM) is a debilitating neurologic condition affecting 1-2% of the population. By definition, individuals with CM experience at least 15 headache days per month (including at least 8 migraine days) for more than 3 months. In addition to frequent, debilitating headaches, CM is associated with increased rates of headache-related disability, psychiatric comorbidity, pain catastrophizing, insomnia, risk of medication overuse headache, and healthcare resource utilization. Established treatments for migraine include medications, vitamin and herbal supplements, neuromodulation, and behavioral treatment strategies. Our study aims to determine whether a novel, home-based behavioral approach, combined biofeedback-virtual reality therapy, can improve self-reported migraine-related outcomes in individuals living with chronic migraine. In this randomized, controlled pilot study, 50 adults with chronic migraine are randomized to the experimental group (frequent use of a heart rate variability biofeedback-virtual reality device plus standard medical care; n=25) or wait-list control group (standard medical care alone; n=25). The primary outcome is reduction in mean monthly headache days between groups at 12 weeks. Secondary outcomes include mean change in acute analgesic use frequency, depression, migraine-related disability, stress, insomnia, and catastrophizing between groups at 12 weeks. Tertiary outcomes include change in heart rate variability and device-related user experience measures.
