Method for evaluating minimum consciousness state degree on the basis of electroencephalogram characteristics

The invention belongs to the technical field of medical diagnosis evaluation, and particularly relates to a method for evaluating a minimum consciousness state degree on the basis of electroencephalogram characteristics. The method comprises the following steps of: S1, collecting electroencephalogram signals; S2, preprocessing the electroencephalogram signals; S3, extracting electroencephalogram signal characteristics; S4, analyzing the electroencephalogram signal characteristics; and S5, visualizing an evaluation result. The method has the characteristics that detection and evaluation accuracy is high, multi-characteristic analysis can be carried out, and state evaluation of patients with different brain region damage conditions is facilitated. 本发明属于医疗诊断评估技术领域，具体涉及基于脑电特征的最小意识状态程度的评估方法。包括以下步骤：S1，脑电信号的采集；S2，脑电信号的预处理；S3，脑电信号特征的提取；S4，脑电信号特征的分析；S5，评估结果可视化。本发明具有检测评估准确度高，能够进行多特征分析，有利于面对脑区受损情况不同的患者状态评估的特点。
