AB - PURPOSE: This study aimed to comprehensively evaluate the inter-rater and test-retest reliability of the Five Step Test (FST) completion time in individuals with chronic stroke, as well as to determine its absolute reliability indices, including the Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC). Additionally, the concurrent validity of the FST was investigated by comparing its results with established clinical measures of motor and balance function.
METHODS: In a cross-sectional design, 40 individuals with chronic stroke (mean age = 59.1 years; mean duration post-stroke = 12 months) underwent FST assessments. Inter-rater and test-retest reliability were analyzed using intraclass correlation coefficients (ICC). SEM, MDC, and MDC% were calculated to quantify measurement error. Concurrent validity was assessed using Pearson’s correlation coefficients between FST performance and scores on the Fugl-Meyer Assessment for the Lower Extremity (FM-LE), Berg Balance Scale (BBS), Timed Up and Go (TUG), and Five Times Sit-to-Stand Test (5STS).
RESULTS: The FST demonstrated excellent inter-rater reliability (ICC = .939; 95% CI = .887–.967) and test-retest reliability (ICC = .901; 95% CI = .820–.946). SEM values were 1.71 and 1.87 seconds, and MDC values were 4.73 and 5.18 seconds ―both below 20% of the maximum completion times. Concurrent validity analyses revealed strong negative correlations with FM-LE (r = −.65) and BBS (r = −.71), and significant positive correlations with TUG (r = .60) and 5STS (r = .67). CONCLUSION: The FST is a highly reliable and valid tool for assessing step and stair negotiation ability in individuals with chronic stroke. Its strong psychometric properties and ease of administration support its use as a practical clinical measure for evaluating lower extremity motor function and balance in this population.
