Background: The Fullerton Advanced Balance (FAB) Scale is recognized for its accuracy and dependability in evaluating balance among elderly individuals. Unlike the Berg Balance Scale (BBS), it minimizes ceiling effects and emphasizes dynamic balance. Additionally, it offers more precise scoring compared to the Mini-BESTest, while being less time-consuming.

Purpose: To determine inter-rater and intra-rater reliability and concurrent validity of Fullerton Advanced Balance scale in patient with chronic stroke.

Method: A group of 55 individuals diagnosed with chronic stroke participated. The FAB Scale was administered by two trained evaluators within a span of three days. Its validity was measured by correlating results from the FAB with scores from the BBS and Mini-BESTest.

Results: Intra-class correlation coefficients (ICCs) were computed to evaluate reliability, while Spearman’s rank correlation was used for assessing concurrent validity. The FAB Scale demonstrated excellent reliability (ICC: intra-rater = 0.975, inter-rater = 0.966) and strong correlation with Mini-BESTest (ρ = 0.882) and BBS (ρ = 0.856).
