Coma Recovery Scale-Revised Predicts Disability Rating Scale in Acute Rehabilitation of Severe Traumatic Brain Injury

Published:January 31, 2023DOI:



      To explore the prognostic value of the Coma Recovery Scale-Revised (CRS-R) in predicting disability outcomes in patients with severe traumatic brain injury using the Disability Rating Scale (DRS).


      Secondary analysis including linear and logistic regressions were performed.


      Data were collected in a previous clinical trial.


      One hundred eighty-four participants across 3 countries (N=184).

      Main Outcome Measures

      Disability Rating Scales.


      Analyses showed an inverse relation between CRS-R scores obtained at baseline and change in DRS scores at 6 weeks. Similarly, changes in CRS-R scores between baseline and 4 weeks were also found to have an inverse relation to change in DRS scores at 6 weeks.


      This study generates a tool that can be used to predict the probability that a patient with severe traumatic brain injury lands in 1 of 3 disability categories. The CRS-R may be useful in prognostication of disability in patients with severe traumatic brain injury.


      List of abbreviations:

      CRS (Coma Recovery Scale), DoC (disorders of consciousness), DRS (Disability Rating Scale), GOS (Glasgow Outcome Scale), MCS (minimally conscious state), VS (vegetative state)
