The Reliability and Concurrent Validity of the Five Step Test in Chronic Stroke Patients

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
