Abstract
The present invention pertains to a portable non-invasive electronic apparatus which can be used to relieve pain or alter the symptoms of certain neurological dysfunctions. A specifically contoured constant current and current limited waveform is generated and applied to selectively positioned electrodes. A program controlled processor tracks usage of the unit to prevent abuse and monitor progress. An overall treatment regimen centered on the stimulator may be effected simply and safely. The invention also provides an apparatus and method for the iontophoretic topical administration of a pharmaceutical agent. The apparatus is operated in a monopolar mode with a particular complex waveform which synergistically enhances the amount of various neurobiochemical species in the cerebral spinal fluid and the blood plasma.
