ABSTRACT
Objectives
To investigate the effect of motivation on improvements in the Functional Independence Measure (FIM) scores in subacute stroke patients with cognitive impairment.
Methods
This retrospective cohort study included 358 consecutive subacute stroke patients with first-ever stroke and Mini-Mental State Examination score ≤23 at admission. We determined motivation and rehabilitation outcome using the vitality index and FIM-motor gain, respectively. Stepwise multiple regression analysis was performed to identify the factors at admission related to FIM-motor gain.
Results
Of 80 participants enrolled in this study (mean age: 74.2 ± 11.3 years). The median (interquartile range) vitality index at admission and FIM-motor gain were 7 (4) and 23 (22) points, respectively. Stepwise multiple regression analysis revealed that age (B, −0.43; 95% confidence interval [CI], −0.65–(−0.21); β, −0.31; P <.001), duration from stroke onset to admission (B, −0.18; 95% CI, −0.33–(−0.04); β, −0.20; P =.014) and Stroke Impairment Assessment Set-motor function (B, 1.27; 95% CI, 0.92–1.61; β, 0.78; P <.001), FIM-motor (B, −0.80; 95% CI, −1.01–(−0.60); β, −0.95; P <.001), and vitality index (B, 3.79; 95% CI, 2.37–5.21; β, 0.50; P <.001) scores at admission were significantly associated with the FIM-motor gain.
Discussion
The vitality index was significantly associated with FIM improvement in subacute stroke patients with cognitive impairment.
