Effects of age on functional independence measure score gain in stroke patients in kaifukuki rehabilitation ward

The influence of age on corrected motor FIM effectiveness

“…However, it is not clear whether age and FIM-M gain have "a linear relationship" in "all ages". In addition, the FIM-M gain decreasing along with every 1-year increase of age differed depending on the FIM-M at admission as reported by Black-Shaffer et al [1] and Tokunaga et al [8] instead of showing a constant value such as 0.24 point. In the report by Tokunaga et al [8], they surveyed average FIM gain in a total of 24 groups of stroke patients stratified by total FIM score at admission into six subgroups and age into four subgroups.…”

In the case the FIM at admission was 36-53 points, average FIM gain of the below 59 years and the over 80 years groups were 51.8 and 19.7 points, respectively, whereas in the case of 108-126 points, the average FIM gain of those groups were 5.6 and 7.0 points, respectively [8].…”

Therefore, subjects need to be stratified by age and FIM at admission when using FIM gain as an outcome in the case of surveying the influence of age on the outcome.…”

Differences in FIM improvement rate stratified by nutritional status and age in stroke patients in kaifukuki (convalescent) rehabilitation ward

“…In previous studies on the relationship between nutritional status and ADL, nutritional status at admission in stroke patients [2], pneumonia patients [16] and heart failure patients [17] affected the ADL outcome, and FIM gain was lower in KRW patients with malnutrition than patients with normal nutritional status [9]. Moreover, in previous studies on the association between age and ADL, ADL outcome became poorer in older stroke patients [7,8], and FIM gain and FIM effectiveness decreased significantly as age increased in stroke patients in the KRW [18,19]. In the present study, among patients with malnutrition, FIM effectiveness was significantly lower in those aged 70s and 80 and older, and these results support previous reports on the relationship of ADL with nutritional status and age.…”

Formula for Predicting FIM Gain and Discharge FIM

“…In other words, we assume that there is a line-shaped relationship (linear relationship) between the objective variable and the explanatory variables. However, the influence of age on FIM gain and discharge FIM changes based on admission FIM [20][21]. In addition, the relationship that FIM gain and discharge FIM decrease in a linear fashion as age increases has not been shown to hold true for all ages [17,18].…”
