Outcome Measures

Primary Outcomes (1)

  • Coma Recovery Scale-Revised for assess the level of consciousness

    Rater Measured the score of Coma Recovery Scale-Revised(CRS-R) within 24h. The CRS-R consists of 23 items grouped in six subscales addressing auditory, visual, motor, oromotor, communication and arousal functions. The lowest item on each subscale represents reflexive activity while the highest items represent cognitively-mediated behaviors.

    24 hours(1 day)

Study Arms (3)

Vegetative state

patients lack awareness of self and environment even in the presence for eye-opening and sleep-wake cycles using CRS-R and GCS

Diagnostic Test: Coma Recovery Scale-Revised and Glasgow Coma Scale

Minimally conscious state

Patients display inconsistent, but reproducible and discernible signs of awareness using CRS-R and GCS

Diagnostic Test: Coma Recovery Scale-Revised and Glasgow Coma Scale

Emergence from MCS

Patients regain accurate communication and/or functional use of objects using CRS-R and GCS

Diagnostic Test: Coma Recovery Scale-Revised and Glasgow Coma Scale

Interventions

Patients have been assessed with both the Coma Recovery Scale-Revised(CRS-R) and the Glasgow Coma Scale(GCS)
