      The Coma Recovery Scale-Revised (CRS-R) is a standardized neurobehavioral assessment measure designed for use in patients with disorders of consciousness.1 There are 6 subscales that assess behaviors mediated by language, visuoperceptual, and motor networks. The items are hierarchically arranged reflecting brainstem, subcortical, and cortically-mediated functions.2 Serial CRS-R assessment has high sensitivity for detecting signs of consciousness. The CRS-R can further distinguish between features of minimally conscious state plus and minimally conscious state minus. The CRS-R may be used to monitor behavioral recovery, predict outcome,3 and assess treatment effectiveness. The CRS-R is a National Institute of Neurological Diseases and Stroke Common Data Element and is recommended by the American Congress of Rehabilitation Medicine, the American Academy of Neurology, and the National Institute on Disability, Independent Living, and Rehabilitation Research for use in clinical practice.4
