- Abstract
Objective:To investigate which conscious behaviour is most frequently detected using the Coma Recovery Scale-Revised in patients with minimally conscious state.Design:Multicentre, cross-sectional study.Setting:One intensive care unit, 8 post-acute rehabilitation centres and 2 long-term facilities.Subjects:Fifty-two patients with established diagnosis of minimally conscious state of different aetiology.Main measures:All patients were assessed by the Coma Recovery Scale-Revised. Results: In most patients (34/52) non-reflexive responses were identified by two or more subscales of the Coma Recovery Scale-Revised, whereas in 14 patients only the visual subscale could identify cortically-mediated behaviours, and in the remaining 4 patients only the motor subscale did so. The clinical signs of intentional behaviour were most often detected by the visual subscale (43/52 patients) and by the motor subscale (31/52), and least frequently by the oromotor/verbal subscale (3/52) of the Coma Recovery Scale-Revised. This clinical pattern was observed independently from time post-onset and aetiology. Conclusions:Non-reflexive visual behaviour, identified by the visual subscale of Coma Recovery Scale-Revised, is the most frequently detected intentional sign consistent with the diagnosis of minimally conscious state, independently from aetiology and time post-onset.
