Objective: In multiple regression analysis, independent variables are typically continuous variables. Individual functional independence measure (FIM) items, however, are ordinal with few levels, and the impact of using them versus admission motor and cognitive FIM scores on predictive accuracy is unclear. This study compared these approaches in predicting discharge motor FIM in stroke patients.

Methods: Data from 742 stroke patients discharged from a convalescent rehabilitation ward were analyzed. Prediction A used age, days from onset to admission, length of stay, admission motor FIM, and admission cognitive FIM as predictors. Prediction B used the 18 individual FIM items instead of admission motor and cognitive FIM scores in a variable-selection regression. Absolute residuals (observed minus predicted) were compared using the Wilcoxon signed-rank test.

Results: Absolute residuals were 9.2±7.1 (median 7.9) for Prediction A and 8.4±6.9 (median 6.7) for Prediction B, with Prediction B significantly smaller.

Conclusion: Using individual FIM items in variable-selection regression yielded higher predictive accuracy than using aggregated motor and cognitive FIM scores. FIM subitems may be useful in multiple regression analysis;however, it should be recognized that they are ordinal scales with a limited number of levels.

Objective: The Enjoji Scale, an Analytical Developmental Assessment for Infants and Toddlers is a comprehensive evaluation method for assessing the development of infants and toddlers from 0 months to 4 years and 7 months of age. It allows for a simple and rapid assessment of development in the motor, social, and language domains. The purpose of this study is to clarify the characteristics of children undergoing rehabilitation treatment at our children specialized hospital when assessed by the Enjoji Scale.

Methods: We analyzed the results of the Enjoji Scale assessments conducted from December 2022 to November 2024. A total of 383 children and 1,067 cases were analyzed.

Results: Decreases were observed in the developmental quotients of the total score, as well as all domains and subdomains, at both chronological and corrected ages, in the entire participants group, as well as in extremely low birth weight infants, children with Down syndrome, and children with neurodevelopmental disorders. In very low birth weight infants, decreases in the developmental quotients of the total score, as well as all domains and subdomains were observed at chronological age, but no clear decreases were evident at corrected age. Children with Down syndrome and neurodevelopmental disorders displayed developmental delays, particularly in language.

Conclusion: The future challenge is to plan and implement appropriate rehabilitation medicine while considering each child’s developmental status and the developmental trends identified for each disease or condition in this study.
