Abstract:
Objective:To construct an objective evaluation system for disorders of consciousness(DOC)on the basis of visual stimulation of wearable device,so as to objectively evaluate DOC patients in clinical practice,and reduce misdiagnosis rate,and provide references for clinical treatment plans aimed at DOC.Methods:Twelve patients with disorders of consciousness,including vegetative state(VS),minimally conscious state(MCS),and suspected VS,who were treated at the Seventh Medical Center of Chinese People's Liberation Army General Hospital from March to May 2019,were selected and included in the DOC group.Twelve healthy subjects recruited during the same period were included in the healthy control group.Based on the Glasgow Coma Scale(GCS),the Coma Recovery Scale-Revised(CRS-R),and the Chinese Vegetative State Scale(CVSS),wearable devices were used to apply visual stimulation to the subjects,and eye movement feedback data were collected to design a quantitative scale.The scores of eye movement data in the visual positioning scheme and the visual tracking scheme were compared and analyzed.Results:The score of the visual tracking scheme in the healthy control group was(0.967±0.033)points,and the score of the visual positioning scheme was(0.005±0.004)points.There were statistically significant differences compared with the scores of patients in the DOC group in the three states(F=97.88,23.04,P＜0.05).According to the distribution characteristics of the eye movement data of the two groups,an objective evaluation scale for DOC was designed.Conclusion:The objective DOC evaluation system based on visual stimulation of wearable device can compensate the defect of higher subjectivity in the assessed results of clinical DOC by the indicators with objective data after it collects feedback data of eye-tracking based on visual stimulation,and processes and analyzes the designed quantitative scale.
