Objective: In a study published in 2002, it was observed that a variable composed by the Functional Independence Measure (FIM™) and the trunk control test at admission predicted 66.5% of the FIM™ at discharge in stroke patients. The objective was to confirm the reproducibility of this predictive model. Methods: Retrospective study of 245 hemiparetic stroke inpatients of the rehabilitation department. The main variables studied were: trunk control test FIM™ at admission and compound variable (FIM™ +trunk control test) as independent variables and FIM™ at discharge and inpatient rehabilitation length of stay as dependent variables. Results: Correlation between the compound variable and the length of stay was statistically significant (r=0.59), as was its correlation with the total FIM™ at discharge (r=0.82). The regression analysis predicted 34.3% of the length of stay variability and 66.4% of the total FIM™ at discharge variability. Conclusion: The compound variable is a reliable tool because of its reproducibility in predicting the functional level at hospital discharge in hemiparetic patients. © 2006 Taylor & Francis.
