The relation between admission balance and functional outcomes following stroke rehabilitation: a medical center...

This prospective study evaluated the clinical use of the Fugl-Meyer Balance Scale (FMBS) on stroke patients during hospitalization and assessed the relationship between balance score at admission to the rehabilitation program and functional outcome at discharge. One hundred and sixty-three stroke patients admitted to the in-patient rehabilitation department of a university-based medical center between January 1 and December 31, 1997 were recruited for this investigation. Functional ability was evaluated with the Functional Independence Measure (FIM) instrument, and balance was measured using the 7-item Fugl-Meyer Balance Scale. These measures were assessed both at admission to and discharge from the inpatient rehabilitation program. Pearson correlation and multiple regression analyses were used to determine the relationship between balance and functional ability scores at admission and rehabilitation outcomes at discharge, including length of stay, functional gain, and efficiency. The results demonstrated that the balance score at admission accounted for 6% of the variation in length of stay, once demographic influences were controlled. The FIM efficiency score could possibly be predicted by the balance ability at admission, which accounted for 3% of the variance. However, the balance score could not provide predictive information about the FIM gain beyond that already provided by the FIM score at admission, which accounted for 4% of the variance with demographic factors controlled. Overall, balance ability at admission, assessed by the Fugl-Meyer Balance Scale, had no or at least only little, contribution to account for the variance in rehabilitation outcomes. These findings suggest that the use of Fugl-Meyer Balance Scale at admission to stroke inpatient rehabilitation seemed not to enhance the ability to predict rehabilitation outcomes.
