Summary
Remote electrical neuromodulation (REN) is an effective, drug-free migraine treatment for veterans, reducing rescue medication use. This wearable device shows significant pain relief and is well-tolerated, supporting its integration into care.
Area of Science:
- Neurology
- Medical Devices
- Pain Management
Background:
- Migraine and headache disorders are prevalent in U.S. veterans, often co-occurring with other conditions.
- Effective, well-tolerated, drug-free treatments are needed for this population.
- Remote electrical neuromodulation (REN) is a non-pharmacological wearable device for acute and preventive migraine treatment.
Purpose of the Study:
- To evaluate treatment patterns, acute medication use, effectiveness, and safety of the REN wearable in U.S. veterans.
- To assess the real-world evidence (RWE) of REN for migraine management in veterans.
- To determine the potential of REN as a drug-free therapeutic option for veterans with migraine.
Main Methods:
- A prospective RWE cohort study of veterans prescribed REN.
- Data collected via the REN mobile application (Nerivio).
- Outcomes included rescue medication use, pain relief, functional disability, associated symptoms, and adverse events.
Main Results:
- Over 28,000 REN treatments were analyzed in 466 veterans.
- 76.7% of treatments did not require prescribed rescue medications.
- Significant pain relief (66.7%), functional disability relief (69.3%), and associated symptom relief (56.5%) were reported.
- Higher effectiveness was observed with early treatment initiation and in females.
Conclusions:
- REN is an effective and safe acute migraine treatment for veterans.
- Most veterans did not need prescribed rescue medications when using REN.
- REN offers a clinically relevant, drug-free option for veterans, supporting its integration into care.
