ABSTRACT:
A method of quantitatively determining and recording constant alternating current conscious perception threshold or current conscious pain perception threshold for the purposes of determining normality or abnormality or corresponding or related anticipated therapy or drug therapy or for monitoring nerve regeneration or functional integrity, comprising the steps of, specifically placing electrodes on the patient according to a predetermined test involving a patient' conscious response, activating a power source, using an integral micro-controller operated digital stimulator, that monitors conscious responses and does not respond to unconscious or vegetative responses and computes the threshold value and registers it after application of a constant current having regard for frequency, waveform, intensity, duration of presentation, and electrode size, calculating and registering data which may be determinative or non-determinative as produced by the integral micro-controller operated unit.
