Abstract[Purpose] The aim of this study was to examine the intrarater and interrater reliability of the Star Excursion Balance Test (SEBT), thereby increasing understanding of its efficient utilization. [Subjects and Methods] There were 67 subjects (49 female; 18 male). For the SEBT, eight lines were made using tape at 45-degree angles from the center of a circle. The experiment was conducted in the following order: the anterior, anterior-medial, medial, posterior-medial, posterior, posterior-lateral, lateral, and anterior-lateral directions. Intraclass correlation coefficients (ICC) (3,1) were used to evaluate the intrarater and interrater reliability (2,1) for each reach distance, while the standard error of measurement (SEM) and smallest detectable distance (SDD) were employed to assess absolute reliability. [Results] For intraratar reliability, the ICC values for all directions ranged from 0.88 to 0.96, SEM values ranged from 2.41 to 3.30, and SDD values ranged from 6.68 to 9.15. For interrater reliability, the ICC values for all directions ranged from 0.83 to 0.93, SEM values ranged from 3.19 to 4.26, and SDD values ranged from 8.85 to 11.82 [Conclusion] The SEBT is a highly reliable tool for measuring dynamic balance. Measurements for intrarater reliability are more reliable than measurements for interrater reliability. When measurement for eight directions was difficult, the SEBT was used. While the anterior, posteromedial, and posterolateral directions employed in the Y Balance Test Kit(TM) can be utilized, this study recommends using the reverse Y Balance Test Kit(TM) method with the posterior direction, not the anterior direction.
