A system for electro-therapeutically treating a patient includes a stimulatory device electromagnetically coupled with the nervous system of a patient, an electrical power supply, and a control mechanism structured to energize the stimulatory device by way of the electrical power supply at a stimulation frequency. The control mechanism is further structured to control the energizing so as to produce a treatment signal encoded in the energizing and having a treatment signal frequency equal to or less than the stimulation frequency.
