Abstract
A method of eliciting analgesia in a human subject by Transcranial Electrical Stimulation (TCES) is provided. Electrodes are secured to the skin of the subject's head and used to apply an electrical current to the electrodes. The current includes a direct current combined with rectangular current pulses (alternating current) delivered at a frequency of between 30 and 65 Hz. The frequency at which the pulses are delivered is periodically changed to a different value within the 30-65 Hz range. The total current supplied, a sum of the DC component and a Mean Absolute Deviation (MAD) of the current pulses, preferably has a value between 0.2 and 20 mA. The method is used during surgery and the post-operative procedure, and may also be used to treat a wide variety of neurological and other conditions.
