An armband that emits mild electric pulses may be an effective new treatment for migraine.
The device, which is strapped around the upper arm during the first few minutes of an attack, can halve symptoms, according to a study of around 70 patients.
The theory is that the electric pulses stimulate nerves under the skin and block pain signals from reaching the brain — and it’s now being tested in a trial of nearly 300 patients.
Migraines, severe headaches, are thought to affect one in five women and one in 15 men in Britain, and cause painful headaches often accompanied by nausea, vomiting or fatigue. An attack can last up to 72 hours and might be preceded or accompanied by flashes of light or aura, tingling, nausea and increased sensitivity to light and sound.
