Outline of Final Research Achievements

The intraoperative auto-analyzing apparatus for free-running electromyogram with operative video and other electrophysiological monitorings was developed to check the patient’s neurological condition before fixing permanent deficits.To use this apparatus, patient’data was gathered in clinical surgery and analyzed. The artifact noise was automatically reduced and free-running Electromyogram waveform was also automatically picked-up. We successfully picked up the true positive free-running electromyogram waveform by the cause of nerve damage from many of false waveforms.
