Functional gain following rehabilitation of recurrent ischemic stroke in the elderly: Experience of a post-acute care rehabilitation setting

The aim of the study was to evaluate whether rehabilitation of patients with recurrent ischemic strokes is associated with functional gain. We studied a total of 919 consecutive post-acute ischemic stroke elderly patients admitted for rehabilitation. 22% out of the patients had recurrent stroke on index day. Functional outcomes of first-ever stroke patients and recurrent ischemic stroke patients were assessed by the Functional Independence Measurement scale (FIM (TM)) at admission and discharge. Data was analyzed by t-test, Chi-square test and by multiple linear regression analysis. There were 716 patients with first ever stroke and 203 patients with recurrent stroke. Total and motor FIM scores at admission and total, motor, gain and Montebello Rehabilitation Factor (RFG) FIM scores at discharge were similar in the two groups. A multiple linear regression analysis showed that age (beta = -0.13, p = 0.001) length of stay (beta = 0.21, p < 0.001), Mini-Mental State Examination score (MMSE) (beta = 0.1, p = 0.01), and admission total FIM (beta = -0.12, p = 0.01) emerged as the only independent predictors of higher gain FIM scores at discharge. The finding suggests that elderly patients with recurrent ischemic stroke admitted to rehabilitation ward, showed similar FIM gain scores at discharge, compared with first-ever stroke patients. It is concluded that recurrent stroke should not be considered as adversely affecting the short-term functional outcomes of patients in a post-acute rehabilitation setting.
