3 The procedure
3.1 Transcutaneous supraorbital nerve stimulation uses small electrical currents to stimulate the supraorbital nerve. It aims to relieve headache and, when used regularly, to reduce the severity and the frequency of migraine attacks.
3.2 Therapy is administered by the patient, using a small battery-operated device (a headband with a central button) connected to a self-adhesive electrode patch applied to the forehead above the eyebrows. When the device is activated, small electrical impulses stimulate the supraorbital nerves (branches of the ophthalmic nerve, the first division of the trigeminal nerve). The intensity of the electrical pulses increases periodically and this can be adjusted by the patient. Stimulation is applied for approximately 20 minutes daily.
3.3 The device can be used to treat acute migraine attacks and for prophylaxis between attacks.
