Abstract
An automated electrophysiological response analysis apparatus for identifying and eliminating signals having non-physiological artifact noise from an averaged evoked potential signal, wherein the apparatus is adapted to identify in an electrophysiological response at least one characteristic representative of non-physiological artifact noise to classify the signal as an artifact signal and remove the artifact signal from a collection of signals used to generate the averaged evoked potential signal.
Claims16
A method for identifying and eliminating signals having non-physiological artifact noise from an averaged evoked potential signal in a patient, the method comprising:
- recording a plurality of resultant waveforms generated by a nervous system of the patient, resulting from stimulation of one or more nerves of the nervous system;
- detecting whether a non-physiological artifact noise is present in at least one resultant waveform by identifying in the at least one resultant waveform at least one characteristic representative of a signal having the non-physiological artifact noise;
- classifying the at least one resultant waveform as an artifact signal if the non-physiological artifact noise is present;
- removing the artifact signal from the plurality of resultant waveforms;
- generating an averaged evoked potential signal from the plurality of resultant waveforms;
- and
- generating positioning effect information about the patient using the averaged evoked potential signal.
