Evaluation method of auditory startle based on brain-computer interface assisted crs-r scale

Abstract

The invention discloses an assessment method of auxiliary CRS-R scale auditory shock based on a brain-computer interface. The assessment method comprises following steps of: 1) selecting simulation, arranging and designing an experimental paradigm; 2), collecting signals; 3) performing data processing; 4) counting inspecting evaluation standards. The assessment method of auxiliary CRS-R scale auditory shock based on the brain-computer interface has following beneficial effects: based on an auditory extraneous experimental paradigm, mismatch negative waves MMN and P300, peculiar to human race, are induced; in combination with an auditory shock assessment method of a coma recovery scale CRS-R, scores of CRS-R auditory shock items are accessed by adoption of the brain-computer interface and a peak detection algorithm; and therefore, the method can not only be effectively used for assessment diagnoses of the coma recovery scale, tracking of recovery effect and selections of a prognosis treatment scheme but also provide scientific and objective detection data to the conventional scale diagnoses in order to ensure authenticity and effectiveness of detection results..

Description

technical field [0001] The invention relates to the technical field of brain-computer interface technology and electrophysiological event-related evoked potentials, in particular to an assessment method for auditory startle based on brain-computer interface-assisted CRS-R scale. Background technique [0002] Since the discovery of the scalp electroencephalogram (EEG) signal at the beginning of the last century, it has been used in the auxiliary diagnosis of nervous system diseases and the study of brain function. People do not need to use traditional neuromuscular channels to realize direct communication between the brain and the outside world, but by studying the main rhythm components in EEG signals, the mechanism of various evoked EEG signals and some specific signals, the spatial position of the signal source and their interaction. relationship to access channels for direct information about the brain's response to the external environment. Brain-computer interface is a...

Problems solved by technology

[0007] The purpose of the present invention is to address the subjectivity of the evaluator in the existing clinical diagnosis technology, the evaluator himself is limited by the movement disorder, the existing ERP evaluation method is too general in the evaluation of the state of consciousness and cannot overcome the existence of the consciousness disorder. For problems such as difficulty in language comprehension, a method for assessing auditory startle based on the brain-computer interface assisted CRS-R scale is provided. This method combines the auditory stimulation form of CRS-R behavior assessment to form a BCI system of the auditory oddball paradigm. To rate the patient's auditory startle and ensure the accuracy and objectivity of the score
