A recent study featuring PISC Executive Committee Member Catherine C. McDonald, PhD, RN, and Senior Scholar David Corwin, MD, compares a Visio-Vestibular Examination (VVE) of adolescent athletes in preseason to postseason. One hundred and fifteen participants were drawn from a private suburban secondary school in the United States. Nine subtests of the VVE were completed prior to and after the athletic season. Results indicate no significant changes in VVE during the pre and postseason. Specifically, abnormalities such as accommodation and complex tandem gait had equal variations in both preseason and postseason testing. The team concludes that Visio-Vestibular function does not vary from pre to postseason among healthy adolescents.
