A Spanish validation of the Coma Recovery Scale-Revised (CRS-R).

RESEARCH DESIGN: Analysis of inter-rater reliability and concurrent validity. OBJECTIVE: To determine measurement properties of a Spanish version of The Coma Recovery Scale-Revised (CRS-R). METHODS AND PROCEDURES: A sample of 35 in-patients with severe acquired brain injury. To test concurrent validity of the translated scale, the Glasgow Coma Scale (GSC) and Disability Rating Scale (DRS) were also administered. Two experts in the field were recruited to assess inter-rater agreement. RESULTS: Inter-rater reliability was good for total CRS-R scores (Cronbach α = 0.973, p = 0.001). Sub-scale analysis showed moderate-to-high inter-rater agreement. Total CRS-R scores correlated significantly (p < 0.05) with total GCS (r = 0.74) and DRS (r = 0.54) scores, indicating acceptable concurrent validity. CONCLUSIONS: The Spanish version of CRS-R can be administered reliably by trained and experienced examiners. CRS-R appears capable of differentiating patients in Emergence from Minimally Conscious State (EMCS) or in Minimally Conscious State (MCS) from those in a Vegetative State (VS).

Early motor predictors of recovery in patients with severe traumatic brain injury.

RESEARCH DESIGN: Retrospective observational study. OBJECTIVE: To compare motor variables between patients with severe traumatic brain injury who emerge and patients who do not emerge from vegetative state, in an attempt to identify early motor manifestations associated with consistent patient improvement. METHODS AND PROCEDURES: Patients were divided into two groups: group 1, patients who emerged from vegetative state attaining at least a state of functional interactive communication and/or functional use of two different objects (n = 8); and group 2, patients who did not emerge (n = 7). Twenty-one motor variables were compared weekly between groups until the end of the treatment programme. RESULTS: Significant differences were observed in head control (p = 0.051) and head turning (p = 0.002) variables, as well as in visual fixation and pursuit (p = 0.051) after a median of 41 days of therapy; and in head control and head turning; visual fixation and pursuit; phonation; pain localization, reach and grasp, and trunk movement (p ≤ 0.051) after a median of 212 days of programme duration. CONCLUSIONS: Head turning, together with or immediately followed by visual pursuit and fixation, proved to be clinically significant variables associated with recovery from vegetative state to higher states of consciousness beyond minimally conscious state.
