The reliability of an instrumented device for measuring components of the star excursion balance test.

The Star Excursion Balance Test (SEBT) is a dynamic test that requires strength, flexibility, and proprioception and has been used to assess physical performance, identify chronic ankle instability, and identify athletes at greater risk for lower extremity injury. In order to improve the repeatability in measuring components of the SEBT, the Y Balance Test™ has been developed.

The purpose of this paper is to report the development and reliability of the Y Balance Test™.
