In an inventive method of performing transcutaneous electrical neural stimulation on a human patient, first and second input electrodes are secured over left and right trapezius muscle regions of the patient. Third and fourth input electrodes are secured over left and right posterior cervical and suboccipital muscle regions of the patient. Fifth and sixth input electrodes are secured over left and right preauricular areas of the patient. A first electrical current is supplied to each of the first and second electrodes. A second electrical current is supplied to each of the third and fourth electrodes. A third electrical current is supplied to each of the fifth and sixth electrodes.
