The intra- and inter-tester reliability of the Modified Star Excursion Balance Test with Hand Reaches
MetadataShow full item record
Context: One of the physical factors of athletic performance is mobility. The relationship between mobility and physical performance has long been debated, but several recent studies have concluded that the reason for this dichotomy is due today isolated conventional mobility tests. Hand reaches is not a common form of mobility testing. Hand Reach Star Excursion Balance Test (HRSEBT) is a set of mobility tests that have systematically combined hand reaches in different directions. HRSEBT is known to be a valid mobility testing. Objective: The purpose of the study is to map the inter- and intrarater reliability of these tests. Design: Observational non-experimental study with repeated measures. Setting: Norwegian School of Sport Sciences – Department of Physical Performance Participants: 30 healthy male participants (26,46 ± 6,21 years, height = 180,20 ± 9.16) were recruited. Measurements: 20 different mobility tests were used in an upright position, 10 on each foot with only the toes on the ground on the opposite foot. HRSEBT places the test person on a mat performing reaches in different directions drawn on the mat which are based on the Star Excursion Balance Test (SEBT). Reach distance is registered in centimeters for all directions except rotation movements that were registered in degrees. All participants were tested by three different testers, resulting in the interrater reliability, while one of the testers tested the participants twice in order to establish the intrarater reliability of the particular tests. Results: For all the 20 measures, the reliability for respectively the interrater reliability and intrarater reliability was excellent. ICC for the interrater reliability was registered to be 0.82, with 95% CI=0.78-0.93. ICC for the intrarater reliability was registered to be 0.82, with 95% CI=0.73-0.93. Conclusion: HRSEBT is a set of tests with high reliability, both between different testers, but also repeatedly by the same tests. HRSEBT can be used safely among testers who have undergone the background of tests and the instructions of the protocol independently of their experience.
