Rehabilitation Outcomes in Patients Who Regained Consciousness

Background/Objectives: Patients with prolonged disorder of consciousness (PDOC) who regained consciousness in intensive care for consciousness rehabilitation (ICCR) were referred to further brain rehabilitation (FBR). The current retrospective cohort study evaluated the functional and cognitive outcomes of FBR. Methods: We assessed outcomes in 258 PDOC patients during FBR and used multivariate regression analyses to examine the influence of demographic and clinical characteristics on outcomes. Results: During FBR, Functional Independence Measure (FIM) motor, cognitive, and total scores improved from 21 ± 11, 11 ± 10, and 32 ± 15 to 43 ± 26, 18 ± 7, and 61 ± 32, respectively (p < 0.001). Dynamic Lowenstein Occupational Therapy Cognitive Assessment (DLOTCA) total scores increased from 57 ± 29 to 82 ± 36, and the average 6-min-walk (6MW) distances improved from 295 to 374 m (p < 0.001). Higher discharge FIM and DLOTCA scores were associated with younger age, traumatic etiology of the brain injury, shorter time to regaining consciousness, and higher FIM and DLOTCA scores at admission to FBR (p < 0.05). Conclusions: We observed functional and cognitive improvement in the examined patients. The improvement was associated with factors that may mainly reflect the severity of brain damage. The findings support continuing rehabilitation before and after emerging from PDOC.
