Abstract
Objective: The purpose of this study was to translate the Spinal Cord Injury Functional Ambulation Inventory (SCI-FAI) into Japanese and verify its reliability.
Methods: The Japanese version of the SCI-FAI was translated according to international guidelines. Study subjects included 34 patients with incomplete spinal cord injuries (mean age 61.8±10.4 years). Two evaluators conducted the SCI-FAI twice on video. Intraclass Correlation Coefficients (ICC) (1, 1) and ICC (2, 1); Cronbach’s alpha coefficient; Weighted Kappa coefficient; and Bland-Altman analysis were used to confirm intra- and inter-rater reliability.
Results: The Japanese version of the SCI-FAI was prepared according to international standards. Intra-rater reliability ICC (1, 1) was 0.928～0.973, Cronbach’s alpha coefficient was 0.967～0.986, Weighted Kappa coefficient was 0.713～1.00, and Bland-Altman analysis showed a fixed error and proportional error in one rater. Inter-rater reliability ICC (2, 1) was 0.848, Cronbach’s alpha coefficient was 0.916, Weighted Kappa coefficient was 0.349～0.899, and Bland-Altman analysis showed no fixed or proportional errors.
Conclusions: The Japanese version of the SCI-FAI was confirmed to be a reliable assessment tool in the Japanese clinical setting.
