Abstract
A method and apparatus for applying electrical stimulation to areas of the nervous system wherein the method permits precise pulse dosage control over prescribed time intervals to be exercised by the administering physician, and the apparatus is organized to provide the desired pulse dosage by means of selectable duty cycle on/off modulation of a pulse train having selectable pulse repetition rates and pulse widths. Digital circuitry is used in a pulse counting technique to implement the generation of pulse sequences such that direct quantitative control may be exercised.
