PURPOSE: Our aim was to describe the changes in the functional outcome at the early phase of rehabilitation following severe brain injury and to identify the factors associated with faster recovery.
METHODS: This retrospective analysis included 182 patients who were transferred from the intensive care unit (ICU) to a post-ICU neurorehabilitation unit following traumatic brain injury (TBI) (n = 82) or cerebrovascular accident (CVA) (n = 100). Admission, discharge and changes in scores were calculated for the Functional Independent Measurement (FIM) and the Wessex Head Injury Matrix (WHIM). Patients with high dynamics of clinical recovery were defined by delta FIM scores ≥22.
RESULTS: Upon admission to the neurorehabilitation unit, 97% of patients had a FIM score <50 and 41% a WHIM score <32. Patients showed significantly improved FIM (+17 points; 7-37) and WHIM (+11 points; 3-19) scores with an over 22-day stay (14-38). Those with faster recovery (45%) were more likely those with high FIM and WHIM scores at admission. The nature and severity of the brain insult were not associated with the dynamics of recovery.
CONCLUSIONS: Within a 2-6 week stay in a post-ICU neurorehabilitation unit, patients with severe disability could achieve partial functional independence and showed cognitive improvements.
