Aim: The current study compared the effectiveness of remote electrical neuromodulation (REN) to that of standard-care medications for acute treatments of migraine, using a within-subjects design. Materials & methods: Post-hoc within-subject analysis was performed on data from 78 adult chronic migraine patients who participated in a clinical trial with REN, on four end points: single-treatment pain relief, single-treatment pain freedom, consistency of pain relief and consistency of pain freedom. Results: No statistical differences were found between REN and the tested medications, in any of the effectiveness outcomes: single-treatment pain relief p = 0.056, single-treatment pain freedom p = 0.532, consistency of pain relief p = 0.369, consistency of pain freedom p = 1.00. Conclusion: The results suggest that REN may provide an effective non-pharmacological alternative for standard care abortive medications in individuals impacted by chronic migraine.

Due to the high frequency of headaches, patients impacted by chronic migraine are struggling with poor quality of life, as well as elevated risk of medication overuse headache (which might cause migraine chronification). Thus, there is a need for non-pharmacological migraine treatments that are both effective and well tolerated. Remote electrical neuromodulation (REN) is a non-pharmacological abortive migraine treatment, which is US FDA cleared for adults and adolescents with episodic or chronic migraine. The current study compared the effectiveness of REN to that of standard-care medications (i.e., over-the-counter medications and triptans), using data from 78 individuals with chronic migraine who participated in a clinical trial. During the study, each participant treated their attacks with their preferred medication for the first 4 weeks, and then treated their attacks with REN (only) for the following four weeks. The participants rated their pain level prior to each treatment, and 2 h after the beginning of the treatment. The results indicate no statistical difference between the effectiveness of REN and standard care medications and suggest that REN may provide an effective non-pharmacological alternative for standard care abortive medications, for individuals with chronic migraine.
