Device for the electrotherapeutic treatment of tension headaches

1. Therapeutic method of treatment of headaches, such as tension headaches and migraines, by a device for the electrotherapeutic treatment of headaches such as tension headaches and migraines, the device comprising an elongated symmetrical element to support two contact electrodes to be applied transversally to the upper part of the face, in the intraorbital region, each of the electrodes being in contact with a self-adhesive conductive gel applied to the surface of the support intended to be applied to the skin of the face, the conductive gel being applied to two given lateral zones mainly covering the entire support with the exception of an insulating central zone, as well as an electric circuit for supplying the electrodes by low voltage electric pulses, the electrode support having a length or lateral extension of between 2.75 and 4.5 inches (70 and 115) mm; and the electrode support having a central part with a height of between 0.6 and 2 inches (15 and 50 mm) and outer parts with a height between 0.2 and 0.8 inches (5 and 20 mm) and a shape so as to allow, independently from the subject, the excitation of afferent paths of the supratrochlear and supraorbital nerves of the ophthalmic branch of the trigeminal nerve, the electric circuit including a programmable signal generator suitable for creating pulses of a duration of between 150 and 450 microseconds with a maximum increase in intensity of 0 to 20 milliamperes at a rate of less than or equal to 40 microamperes per second and with a step up in intensity not exceeding 50 microamperes; the method comprising:

placing the self-adhesive electrode support on the upper part of the face in the intraorbital region so as to cover, on each side, the afferent paths of the supratrochlear and supraorbital nerves of the ophthalmic branch of the trigeminal nerve;

generating an electrical signal by the programmable signal generator comprising rectangular pulses with a duration of between 150 and 450 microseconds, with a maximum increase in intensity of 0 to 20 milliamperes, at a rate of less than or equal to 40 microamperes per second, said increase in intensity being produced with a step up not exceeding 50 microamperes;

applying said electrical signal to the electrodes to provide direct stimulation of the supratrochlear or supraorbital nerves to treat tension headaches and migraines.
