Objective: To use three different methods to elucidate
the association between the degree of improvement in
the motor items of the Functional Independence
Measure (motor FIM gain) and cognitive ability.
Methods: The subjects were 1,101 cerebral stroke
patients admitted to Kaifukuki rehabilitation wards.
Three different methods were used to investigate the
association between total score on FIM cognitive
items on admission (cognitive FIM on admission) and
motor FIM gain: (1) multiple regression analysis with
motor FIM effectiveness as the target variable, (2)
multiple regression analysis with motor FIM on
admission restricted to narrow bands, and (3)
adjustment using a standard severity distribution.
Results: In multiple regression analysis used in
methods (1) and (2), cognitive FIM on admission was
selected as an explanatory variable, with a positive
coefficient of regression. In method (3), mean adjusted
motor FIM gain for dementia patients was lower than
mean motor FIM gain for non-dementia patients.
Conclusion: All three methods were capable of
showing that FIM gain increases with higher cognitive
function.
Key words: FIM effectiveness, multiple regression analysis, FIM gain, stratification
