Purpose: The purpose of this study was to clarify the effects of age on the gain of Functional Independence Measure (FIM) total scores in stroke patients.
Methods: A total of 1,572 stroke patients who were discharged from the kaifukuki rehabilitation ward of Hospital A were studied. The patients were classifi ed into six groups according to their FIM scores at the time of admission (AFIM scores), and further divided into four groups according to their ages (59 years or younger, 60 to 69 years, 70 to 79 years, and 80 years or older). The mean FIM score gains of these 24 groups were compared.
Results: FIM score gain decreased signifi cantly as the age of the patients increased in the groups with AFIM scores from 18 to 107 points. In the group with AFIM scores of 36 to 53 points, the mean FIM score gain in patients aged 80 years or older (19.7 points) was 38% of that in patients aged 59 years or younger (51.8 points). In the group with AFIM scores of 108 to 126 points, the relationship between age and FIM score gain was unclear.
Conclusion: The FIM score gain in older patients was signifi cantly lower than that in younger patients, except in the group with AFIM scores of 108 to 126 points in which a ceiling effect was observed.
