FIM(TM) was developed to resolve the long-standing problem of lack
of uniform measurement and data on disability and rehabilitation
outcomes (Granger, 1998). The FIM(TM) emerged from a thorough developmental
process, sponsored by the American Congress of Rehabilitation Medicine
and the American Academy of Physical Medicine and Rehabilitation
(Granger et al., 1986). A National Task force reviewed 36 published
and unpublished functional assessment scales before agreeing on
an instrument (Hamilton et al., 1987).
scores range from one to seven: a FIM(TM) item score of seven is
categorized as "complete independence," while a score of one is
"total assist" (performs less than 25% of task). Scores falling
below six require another person for supervision or assistance.
FIM(TM) measures independent performance in self-care, sphincter
control, transfers, locomotion, communication, and social cognition.
By adding the points for each item, the possible total score ranges
from 18 (lowest) to 126 (highest) level of independence.
rehabilitation, admission and discharge scores are rated by clinicians
observing patient function. Functioning post-discharge can be accurately
assessed using a telephone version of FIM(TM) when administered
by qualified, trained interviewers.
