Intra- and Interrater Reliability of the Directional Balance and Reach Tests With and Without Rotation

Abstract

This study investigated whether the directional balance and reach with and without rotation is a reliable screening tool to measure dynamic balance and ability to control motion in three planes. Twenty healthy, collegiate athletes participated. The directional balance and reach exhibited good to excellent levels of intra- and interrater reliability (intraclass correlation coefficient = .77–.99). The directional balance and reach provides clinicians with a reliable method that requires minimum financial, spatial, and temporal costs to administer in small and large screening, training, and evaluation programs to recognize asymmetries and deficits in assessing dynamic balance in all three planes of motion.
