Cutoff Value of the FGA According to the FAC

FAC Cutoff value Sensitivity Specificity AUC (95% CI)
FAC ≥1 from FAC 0 .5 .906 1.000 .953 (.926 to .980)
FAC ≥2 from FAC ≤1 5.5 .919 .919 .966 (.943 to .989)
FAC ≥3 from FAC ≤2 10.5 .940 .926 .979 (.962 to .995)
FAC ≥4 from FAC ≤3 14.5 .881 .881 .954 (.929 to .980)
FAC 5 from FAC ≤4 18.5 .864 .867 .959 (.935 to .983)

FGA: Functional Gait Analysis; FAC: Functional Ambulation Category; FAC 0 = nonfunctional ambulator; FAC 1 = dependent on physical assistance(level 2, continuous manual contact); FAC 2 = dependent on physical assistance(level 1, intermittent touch); FAC 3 = dependent on supervision; FAC 4 = independent, level surface only; FAC 5 = independent, everywhere.
