Objective: This study aimed to clarify the influence of
age on rehabilitation outcome by using corrected
motor FIM (FIM-M) effectiveness, an outcome
indicator in which the influence of FIM-M at admission
was corrected.
Methods: The subjects were 1,101 stroke patients.
The value of A in the equation, Corrected FIM-M
effectiveness = FIM-M gain / (A-FIM-M at admission)
was set as 42, 64, 79, 83, 87, 89, and 91 points (for
FIM-M score at admission of 13-18, 19-24, 25-30,
31-36, 37-42, 43-48, and 49-90 points, respectively).
The subjects were divided into 10 groups by age with
a 5-year range in which the average of corrected
FIM-M effectiveness was calculated.
Results: The mean corrected FIM-M effectiveness
was almost constant in five groups below 69 years and
decreased almost linearly as age increased in five
groups over 70 years.
Conclusion: The outcome decreases almost linearly
after the age of 70 years old.
Key words: corrected motor FIM effectiveness, age, outcome
