Deficits in Disease and Patient Oriented Outcomes in Adolescents with Chronic Ankle Instability

The purpose of this study is to determine if adolescents with chronic ankle instability (CAI) display similar deficits in performance of the star excursion balance test (SEBT) as a result of decreased dorsiflexion range of motion (DF]ROM) when compared to adolescents with no injury history. Adolescent participants will be measured for DF]ROM and will perform the anterior, posterolateral, and posteromedial direction tasks of the SEBT. This is a case-control study in which participants ages 12-17 will be pre]screened for inclusion criteria through the use of PROs, being placed into the CAI or healthy control group through guidelines set by the International Ankle Consortium. We expect that adolescent participants with CAI will display poorer measures on the SEBT in the anterior, posterolateral, and posteromedial directions as a result of diminished DF]ROM.
