Coma recovery scale-revised with and without the emotional stimulation of caregivers

The Coma Recovery Scale-Revised (CRS-R) is the gold standard of responsiveness assessment in patients with disorder of consciousness. The purpose of this study is to search for the efficacy of the caregivers' involvement in the evaluation of responsiveness in these patients. Responsiveness assessment was performed in 15 patients with CRS-R. The CRS-R was administered with and without the emotional stimulation of the primary caregiver at different times. Our preliminary findings seem to suggest that, including also the caregivers during CRS-R assessment, may obtain better responsiveness scoring than that obtained by professionals and might reduce the misdiagnosis rate.
