Validation to Brazilian Portuguese of the coma recovery scale-revised

To improve the diagnostic accuracy of the state of consciousness of patients with severe brain injury, Giacino et al. introduced the Coma Recovery Scale (CRS) in 1991, which underwent revision in 2004, resulting in the revised CRS scale (CRS-R). To determine the concurrent validity, as well as inter- and intrarater agreement of the CRS-R's adaptation to Brazilian Portuguese. This study involved a sample of 30 patients with severe brain injury. Concurrent evaluations were also performed with the Glasgow Coma Scale (GCS) and the Full Outline of UnResponsiveness (FOUR) scale. A total of seven rehabilitation experts were recruited to assess the inter- and intrarater reliability agreement. Interrater reliability was moderate to high for auditory, visual, motor, verbal, communication, and arousal subscales (Cohen weighted kappa = 0.765 to 0.892;
