Dynamic balance is an integral component in screening lower extremity injury risk. Previous research has identified the need to create sport and competition level specific dynamic balance injury cut points. The purpose of this study was to determine if dynamic balance differences exist, utilizing the Lower Quarter Y-Balance Test (YBT-LQ), across varying competition levels (middle school, high school, college and professional) in basketball players. Subjects were participating at the middle school (MS; n=88), high school (HS; n=105), college (COL; n=46), and professional levels (PRO; n=41).
