ABSTRACT:
An electric nerve stimulation device and apparatus for suppressing organic pain and other functional disorders of the nervous system without noxious sensation and substantially free from the adaptation phenomenon which usually results from subjecting receptors and nerve cells to uniform stimulating signals. The device includes a pulse generator to produce bipolar rectangular waveforms at preselected repetition rate and of a preselected width during a given first time period. Electronic circuits are connected to the post generator to deliver rectangular waveforms at a repetition rate which is chosen by a pseudo-random function for a second time period which is also chosen by a pseudo-random function. Further circuitry is provided to inhibit delivery of pulse waves for a third period of time. This third period of time is chosen by a pseudo-random function, thereby substantially eliminating noxious sensations and adaptation of nerve cells to stimulation during suppression of the organic pain. Electrodes are connected to the output of the device to apply the waveforms to nerve fibers to be stimulated thereby.
