The Food and Drug Administration this week approved a new device for preventing migraines.
The battery-powered headband stops migraine pain by sending an electrical signal through a person's forehead to a nerve that plays a key role in migraines.
The headband could mean drug free pain relief for people who suffer from debilitating headaches.
How does it work?
The company says the device delivers electric impulses to the main branch of the trigeminal nerve.
The headband showed success, NPR News reports, in preventing headache pain in a study involving 67 people.
Some participants in the study got the new Cefaly device and others used a sham headband. The people who wore the Cefaly device 20 minutes a day took fewer migraine medicines than those who got the dummy device.
And The Associated Press reports on a separate study, which found that around 53 percent of 2,313 patients were satisfied with the headband and said they were willing to purchase it for future use.
No serious adverse events were connected with the device.
