Objective: To clarify the relationship between cognitive Functional Independence Measure (FIM) and motor FIM gain. Methods: We examined 1,137 patients with stroke in a Kaifukuki rehabilitation ward. Both motor and cognitive FIM scores at admission were divided into six separate groups (three groups per parameter), and we then compared these groups with motor FIM gain as the objective variable. We also performed a multiple regression analysis using motor FIM gain as the objective variable. Results: In the groups where motor FIM scores at admission were 13-38 points and 39-64 points, motor FIM gain was significantly higher in individuals that had high cognitive FIM scores at admission. In the multiple regression analysis, we found that motor FIM gain increased by 0.889 points when cognitive FIM scores at admission increased by 1 point in patients whose motor FIM score at admission was between 13 and 34 points and whose cognitive FIM score at admission was between 5 and 14 points. Conclusion:This study clarified the relationship between cognitive FIM scores at admission and motor FIM gain in individuals with stroke.

The difference between measured Nichijo-seikatsu-kino-hyokahyo (NSKH) score and predicted NSKH score derived from ADL is related to FIM gain. Jpn J Compr Rehabil Sci 2013; 4: 61-66. Purpose: To determine if the difference between measured Nichijo-seikatsu-kino-hyokahyo score (NSKH) and predicted NSKH score (measured NSKH-predicted NSKH) derived from the Functional Independence Measure (FIM) score is related to FIM gain, and whether it increases the predictive accuracy of FIM gain. Methods: We studied 102 stroke patients in the Kaifukuki rehabilitation ward with FIM scores at admission between 18 and 58. We analyzed whether a correlation exists between "measured NSKHpredicted NSKH" and "FIM gain", and performed a multiple regression analysis to predict FIM gain. Results: A significant negative correlation (correlation constant −0.275, p<0.01) was detected between measured NSKH-predicted NSKH and FIM gain. The adjusted R-square value increased by 0.101 after incorporating measured NSKH-predicted NSKH into the predictive equation for FIM gain, which included age and FIM score at admission. Conclusion:This study demonstrates that measured NSKH-predicted NSKH correlates with FIM gain, and that measured NSKH-predicted NSKH is an index that increases the predictive accuracy of FIM gain.

Objective: There are several methods for inter-hospital comparison of the improvement in Functional Independence Measure (FIM). However, it is not known which method is most suitable. The purpose of this study was to elucidate which of 4 methods can most successfully compare the average improvement in motor FIM (mFIM) at each hospital with the least influenced by the difference of mFIM score at admission. For this purpose, we considered 3 groups divided based on motor FIM score at admission as 3 hospitals. Methods:The subjects were 575 stroke patients hospitalized in a convalescent rehabilitation ward. We divided the subjects into 3 groups based on mFIM score at admission (13 to 38 points, 39 to 64 points, and 65 to 90 points) and investigated whether there were significant differences in the values derived from mFIM effectiveness, corrected mFIM effectiveness, deviation value of mFIM gain, and multiple regression analysis. Result:Significant difference in the improvement in mFIM between 3 groups divided by mFIM at admission was not observed only for the use of the deviation value of mFIM gain. Conclusion:Deviation value of mFIM gain, which is the least liable to the influence of differences in mFIM score at admission, is useful as a method to compare average improvement in mFIM among hospitals.
