*Federal Register* notice: FDA is classifying the trunk and limb electrical stimulator to treat headache into Class 2 (special controls). The decision is based on a Theranica Bioelectronics de novo classification request for its Nerivio Migra device. The agency has identified it as a device intended to treat headache through the application of electrical stimulation anywhere on the body apart from the patient’s head or neck through electrodes placed on the skin. The stimulation may be provided transcutaneously or percutaneously. To view the notice, click [here](https://www.govinfo.gov/content/pkg/FR-2021-12-02/pdf/2021-26175.pdf?ref=fdaweb.com).
