London: Scientists have developed a `Star Trek` style band which they claim could prevent migraines when worn across the forehead for twenty minutes a day.The device called Cefaly delivers electric impulses to the supraorbital nerve that controls sensation in and around the eye.In a study published in the journal Neurology, researchers found that those who used it were suffering about a third fewer debilitating headaches after a couple of months.The number of people whose migraines were reduced by half or more were also tripled, the `Daily Mail` reported."The device consists of a thin silver band that looks like something out of Star Trek. It is hooked over the ears and worn across the forehead like futuristic sunglasses. Patients don it once daily for 20 minutes," Professor Jean Schoenen from Liege University in Belgium said.
