Validity of the Star Excursion Balance Test as an assessment of the balance ability for community-dwelling elderly people / 体力科学

ABSTRACT

The purpose of this study was to consider the validity of measuring the Star Excursion Balance Test (SEBT), which has been used as a measure of balance ability in athletes, for community-dwelling elderly people. To achieve this purpose, we examined the relationship between the existing balance ability measures, leg strength, and the SEBT. The subjects were 36 elderly people (mean age 71.1 years). We used the SEBT, functional reach test (FRT), timed up-and-go test (TUG), and Mini-BESTest to evaluate balance ability and the 30-second chair-stand test (CS-30) to assess leg strength; we also assessed the 10-m walk time. The correlation coefficient with the SEBT was calculated. The significant level was 5%. A significant positive correlation was observed between the total score of Mini-BESTest and the SEBT reach distance in the anterior direction (r = 0.364, p < 0.05) and the posteromedial direction (r = 0.407, p < 0.05). A significant positive correlation was observed between anticipatory postural control and the SEBT reach distance in the anterior directions (r = 0.403, p < 0.05), and postural responses and SEBT reach distance in the posterolateral direction (r = 0.360, p < 0.05), which were subsystem category of Mini-BESTest. No significant correlation was found in the other items. The correlation with Mini-BESTest indicates that SEBT might be a valid tool to evaluate the dynamic balance ability of community-dwelling elderly people. However, their correlation coefficient is not high, suggesting that SEBT can evaluate elements different from Mini-BESTest.
