본 연구의 목적은 뇌졸중 환자들의 플러턴 어드밴스드 균형 척도(Fullerton Advanced Balance Scale, FAB)의 신뢰도와 타당도를 알아보고자 하였다. 연구에 참여한 19명의 뇌졸중 환자를 대상으로 FAB 개별 항목의 검사-재검사 신뢰도는 카파계수, 총점은 급간내상관계수(Intra Class Coefficient, ICC)와 최소 감지 변화(Minimal Detectable Change, MDC)를 이용하였다. FAB의 동시 타당도는 버그균형척도(Berg Balance Scale, BBS), 일어나 걸어가기 검사(Timed Up & Go Test, TUG), 퓨글 마이어 상하지 운동 기능(Fugl Meyer Assessment-Upper/Lower extremity, FMA-U/E·L/E)간의 스피어만 상관 계수(Spearman Correlation Coefficient)를 이용하였다. 연구 결과 FAB의 1, 6, 8번 항목의 카파 계수는 .77(높음), 2∼5번, 7, 9, 10번 항목은 .83∼1.00(매우 높음)이었다. FAB 총점의 ICC=.97, 내적 일치도는 크론바 알파 .86 이상, MDC는 1.63으로 FAB 최고 점수인 30점의 10% 미만(3점)으로 신뢰도가 높은 것으로 나타났다. FAB의 동시 타당도는 BBS(r=.85), TUG(r=-.82)와는 높은 상관관계(p<.001), FMA-U/E(r=.58), FMA-L/E(r=.62), FMA-총합(r=.69)과는 중간 정도의 상관관계(p<.01)가 있는 것으로 나타났다. 따라서 FAB는 신뢰도와 타당도가 높고 뇌졸중 환자들의 균형 능력을 평가하는데 유용한 평가 도구임을 확인하였다.

The purpose of this study is to identify the reliability and validity of the Fullerton advanced balance scale(FAB) for stroke patients. For 19 stroke patients who participated in this study, the test-retest reliability of each FAB item was identified based on kappa coefficient and the total score was identified based on the intra class coefficient(ICC) and minimal detectable change(MDC). The concurrent validity of FAB was identified based on Berg Balance Scale(BBS), Timed Up & Go Test(TUG), Fugl Meyer Assessment-Upper/Lower extremity (FMA-U/E·L/E) and Spearman Correlation Coefficient. According to the results of this study, the kappa coefficient of items 1, 6 and 8 of FAB was .77(high), and that of items 2 to 5, 7, 9 and 10 was .83 to 1(very high). The ICC score of FAB total score was .97. The internal consistency, Cronbach alpha value, was more than .86. MDC score was 1.63, which was less than 10%(3 points) of the FAB highest score of 30, showing high reliability. The concurrent validity of FAB was highly correlated(p<.001) with BBS (r=.85) and TUG(r=-.82), and moderately correlated(p<.01) with FMA-U/E(r=.58), FMA-L/E(r=.62), and FMA-total(r=.69). This means that FAB is highly reliable and valid and useful for evaluating the balance ability of stroke patients.
