Context: The Star Excursion Balance Test (SEBT) is a widely accepted method of assessing dynamic postural stability. The Y Balance Test (YBT) is a commercially available device for measuring balance that uses 3 (anterior, posteromedial, and posterolateral) of the 8 SEBT directions and has been advocated as a method for assessing dynamic balance. To date, no studies have compared reach performance in these tests in a healthy population. %26lt;br%26gt;Objective: To determine whether any differences exist between reach distance performance for the anterior, posteromedial, and posterolateral directions of the SEBT and the YBT. %26lt;br%26gt;Design: Descriptive laboratory study. %26lt;br%26gt;Setting: University motion analysis laboratory. %26lt;br%26gt;Patients or Other Participants: A total of 20 healthy active male participants (age = 22.50 +/- 3.05 years, height = 1.78 +/- 0.82 m, weight = 79.48 +/- 11.32 kg, body mass index = 24.96 +/- 2.56 kg/m(2)). %26lt;br%26gt;Intervention(s): Participants carried out 3 trials in each reach direction on each leg on the SEBT and the YBT a minimum of 1 week apart. %26lt;br%26gt;Main Outcome Measure(s): The means of the 3 trials in each direction on each leg on both tests were calculated. Data were collected after 4 practice trials in each direction. Paired t tests and Bland-Altman plots were used to compare reach distances between the SEBT and the YBT. %26lt;br%26gt;Results: Participants reached farther in the anterior direction on the SEBT than on the YBT. No differences were observed in the posteromedial and posterolateral directions. %26lt;br%26gt;Conclusions: Differing postural-control strategies may be used to complete these tasks. This finding has implications for the implementation and interpretation of these dynamic balance tests.
