Introduction
Migraine is a chronic neurological disorder causing severe pain and disability in more than a billion people worldwide. Ideal treatment should provide long-term efficacy with minimal side effects. Previous studies indicate that remote electrical neuromodulation (REN) is an efficacious and safe treatment option for the acute treatment of migraine in clinical practice. This study examined long-term safety, utilization, and efficacy of REN during 12 consecutive usage months.
Methods
Data from patients with migraine across the USA using REN to treat their migraine attacks were electronically collected from the Nerivio® device. All patients who used REN during 12 consecutive months were included, and data were compared across months. Safety was assessed by the number and type of adverse events. Utilization was measured by the number of monthly treatments. Efficacy was evaluated as consistent change in headache pain intensity, functional disability, and disappearance of associated symptoms from baseline to 2 h post treatment.
Results
Data were analyzed from 409 people living with migraine who treated with REN for 12 consecutive months, performing a total of 39,531 treatments. The incidence of device-related adverse events (dAEs) was 1.96% (8/409), including two negligible (0.49%), five mild (1.22%), one moderate (0.24%), and no severe events. All patients continued treatment with REN despite dAEs. One-year average monthly utilization was 8.05 treatments (SD 1.15). Month-to-month utilization did not change during 12 months of consecutive use [F(4.895, 1997.204) = 2.014, p = 0.075, repeated-measures ANOVA]. One-year average efficacy showed 74.1% of users reported consistent 2-h pain relief, and 26.0% reported consistent pain freedom. Month-to-month pain relief and pain freedom did not change during 12 months of consecutive use [F(11, 1069) = 0.55, p = 0.873 and F(11, 1295) = 0.69, p = 0.750 respectively; generalized linear mixed model analysis].
Conclusion
REN is a safe and well-tolerated acute migraine treatment, with stable efficacy and utilization over 1 year, making it an advantageous non-drug option for the long-term management of this chronic disease.
