Abstract
Migraine modulator apparatus and methodology employs a transcutaneous electronic wave to reduce and control migraine headaches. A first positive contact electrode is placed at the pain site and a second positive contact is placed at the web of the contra-lateral hand; a first negative contact is placed at the contra-lateral trapezius origin, and a second negative contact electrode is placed at the web of the ipsilateral hand. An electronic current wave comprising relatively high frequency pulses with a low frequency amplitude modulation is then applied between the positive and negative electrodes.
