Abstract
This study was conducted to compare the Extended Barthel Index (EBI) to the Functional Independence Measure (FIM) and the Expanded Disability Status Scale (EDSS) as a measure used to assess changes in a patient's need for help with activities of daily living. One hundred patients with multiple sclerosis were evaluated by the same person upon arrival in a rehabilitation clinic and four weeks later. EBI and FIM both proved to be far more sensitive in detecting changes than the EDSS (29% of patients changed their EBI score, 32% their FIM score, 5% their EDSS score). EBI and FIM showed a very high correlation (Spearman correlation coefficient r s = 0.9705). Both scales correlated somewhat less with the EDSS (r s = -0.7624, resp. -0.7611). Considering the high correlation and equal sensitivity of EBI and FIM, the study recommends the use of the EBI, since it has a simpler rating system and the elimination of some redundant FIM items increases user-friendliness and compliance.
