Abstract
Migraine is a common condition affecting approximately 1.04 billion people worldwide. Despite the available pharmaceutical therapies, patients with migraine often prefer, or may require, non-medicinal treatments for their disease. External trigeminal nerve stimulation (e-TNS) is a non-invasive, non-drug device treatment approved by the US Food and Drug Administration for the prevention and acute treatment of migraine. The trigeminovascular system plays a key role in migraine pathophysiology; e-TNS percutaneously stimulates the supraorbital and supratrochlear branches of the ophthalmic division of the trigeminal nerve. This article reviews published studies of e-TNS in the prevention and acute treatment of migraine, highlights the versatility of e-TNS in individualizing migraine treatment and discusses future directions for research and clinical applications of e-TNS therapy.
