Brief Summary

In recent years, promoting wakening attempts in patients with disorders of consciousness are increasing, but there are a lack of objective indicators to evaluate the efficacy and further researches on the brain mechanism during the wakening processing. So, the study first assessed the cerebral response during emotional acoustic stimuli with quantitative EEG and ERP(Event-related potential), and next, the investigators explored the relationship between brain activation and patients' recovery.

Outcome Measures

Primary Outcomes (1)

  • Glasgow Outcome Scale (GOS)

    A GOS value of \<3 was considered as a bad recovery, while a GOS value of ≥3 was considered as a good recovery

    In one year

Secondary Outcomes (1)

  • quantitative electroencephalography

    30 minutes before the auditory stimualtion and 30 minutes after each stimulation

Other Outcomes (1)

  • N1,P300,LPP

    From 200 msec before the stimuli onset to 1000ms after the auditory stimulation

Study Arms (2)

patients with disorders of consciousness

EXPERIMENTAL

3 minutes stimulation with music,name,and noise separately,each are separated with a 5 minutes washout period.

Device: music,name,and noise sound

healthy control group

EXPERIMENTAL

3 minutes stimulation with music,name,and noise separately,each are separated with a 5 minutes washout period.

Device: music,name,and noise sound

Interventions

A 5-minute baseline silence was followed by the presentation of three contrasting auditory stimuli(music,name,and noise), with a 2-minute washout silence separating each stimulus

healthy control grouppatients with disorders of consciousness
