Impact of Neurorehabilitation on Disability in Patients with Acutely and Chronically Disabling Diseases of the Nervous System Measured by the Extended Barthel Index

Abstract

To study the impact of rehabilitation on disability in an unselected patient group with acutely and chronically disabling neurologic diseases, the Extended Barthel Index (EBI) was determined at the beginning and at the end of the rehabilitation stay in all patients admitted to our Neurorehabilitation Centre in Valens, Switzerland. Patients who reached the highest possible EBI score at entry ("ceiling effect"), with a short stay (<1 week), or with a deterioration due to other medical complications were excluded. Finally EBI data of 743 patients could be analyzed. The mean EBI at entry was 45 and 51 at discharge. The mean increase of the EBI score per week was 1.1 (SD, 1.7). The change of the EBI score was analyzed independently in patients with acute neu rologic diseases admitted in the postacute phase (acute group) and patients with chron ically disabling neurologic diseases (chronic group). As expected, the increase of the EBI score was higher in the acute group than in the chronic group; 80.8% of the acute group patients and 42.5% of the chronic group patients showed an increase of the EBI score at discharge. Both groups showed a significant EBI gain with a marked shift to higher EBI scores at discharge. The mean gain per week was 1.6 in the acute group and 0.5 in the chronic group, respectively. Analysis of EBI changes considering the different underlying diseases showed the highest increase in patients with stroke and traumatic brain injury. Key Words: Extended Barthel Index—Disability—Neuro— rehabilitation.
