Objective:
To assess and compare the consequences for outcome in terms of the dimensions of activity and participation for two groups: group A, which received early formalized rehabilitation, and group B, which received late or no formalized rehabilitation.
Research Design:
A cross-sectional study.
Procedure:
Twenty-six patients (A: n = 14 and B: n = 12) with severe brain damage were included. The participants were assessed a mean of 26.6 months (SD 7.1, median 25, range 14-41) after the incident using the structured form for the Swedish Neuro database, the Glasgow Outcome Scale (GOS), the Extended Glasgow Outcome Scale (GOSE) and the Functional Independence Measure (FIM).
Results:
The study reveals a better outcome for group A. No patient remained in a vegetative state in group A as compared with three in group B. In group A, 50% were independent as compared with 17% in group B. The frequency of return to work was 43% in group A, but no patient in group B had returned to work.
