Role of Intensive Inpatient Rehabilitation for Prevention of Disability after Stroke: The Korean Stroke Cohort for Functioning and Rehabilitation (KOSCO) Study

ABSTRACT

The objective was to investigate the effects of the intensive inpatient rehabilitation treatment during subacute phase to reduce disabilities at chronic phase in patients with first-ever stroke. This study presents interim results of the Korean Stroke Cohort for Functioning and Rehabilitation (KOSCO). Stroke patients who transferred to the rehabilitation department during the 1st hospitalization were classified into the intensive rehabilitation group, and the other stroke patients were classified into the nonintensive rehabilitation group. Disability grade at subacute phase and 6 months after stroke was defined using the Korean modified Barthel Index (K-MBI). The change of disability grade at chronic phase was analyzed by the intensive inpatient rehabilitation treatment. A total of 5,380 first-ever stroke patients were included in this analysis. Among these 5,380 patients, 1,162 and 4,218 patients were classified into the intensive rehabilitation group and the non-intensive rehabilitation group, respectively. The proportion of patients to improve the disability grade at 6 months after stroke was significantly higher in the intensive rehabilitation group than the non-intensive rehabilitation group with severe functional impairment at subacute phase (p < 0.05). This study revealed that the intensive inpatient rehabilitation treatment during subacute stage could significantly improve the disability grade at chronic phase in first-ever stroke patients.
