RESUMO
OBJECTIVE: To describe the clinical characteristics and short-term pattern of evolution of a sample of patients within 1 year after acquiring a brain injury that led to a vegetative state (VS) or a minimally conscious state (MCS). DESIGN: Cohort study. SETTING: Inpatient brain injury rehabilitation program. PARTICIPANTS: Patients with acquired brain injury (N=32; 47% traumatic, 37.5% hemorrhagic, 15.5% anoxic) who were in a VS or an MCS according to Coma Recovery Scale-Revised (CRS-R) scores. INTERVENTION: Integrative multisensory program comprising daily physical rehabilitation procedures and multimodal sensory stimulation. MAIN OUTCOME MEASURE: All patients were assessed with a Spanish version of the CRS-R at admission and then monthly for at least 6 months or until emergence from MCS. RESULTS: At the time of admission, 12 patients were diagnosed as being in a VS and 20 as being in an MCS. Eight patients were able to emerge from their MCS during follow-up. Seven of these 8 patients were diagnosed as being in an MCS at inclusion, and only 1 was diagnosed as being in a VS. Emergence from an MCS was mostly associated with improvement in both the communication and motor function scales (n=4). Lesser chronicity (P=.01) and the presence of more than visual behavioral responses at admission (P=.05) were both significant predictors of emergence from an MCS. CONCLUSIONS: The CRS-R seems appropriate for establishing an immediate prognosis in this population. A quick referral of these patients for specialized assessment and rehabilitation facilities is recommended.
