Predicting Ankle Injury Through Clinical Functional Measures in Adolescent Athletes

The objective of this study is to determine if a clinical measure of dynamic postural
control, the star excursion balance test (SEBT), and a simple functional testing battery,
the Functional Movement Screen (FMS), can be used effectively to predict ankle injury in
high school and collegiate athletes across a variety of sports.

Males and females between the ages of 14 and 24 enrolled at one of three designated high
schools in Toledo, OH or at the University of Toledo will be recruited for this study.
Eligible participants will be signed up and medically cleared to participate in football,
basketball, baseball, softball, soccer, volleyball, and/or cross country during the
2012/2013 academic year. Participants will be healthy and must be cleared by a physician
for full participation at the time of enrollment in the study. All the enrolled student
athletes will be made aware of the study and the requested prior to their pre-season
physicals by the coaching staff and ATC prior to the beginning of the first day of practice.
Consent and assent will be obtained using appropriate university approved forms. In this
prospective study design, pre-season dynamic postural control data and previous injury
history will be collected from the high school and collegiate athletes. These athletic
facilities are all serviced by certified Athletic Trainers (ATC) and physicians associated
with the University of Toledo and the University of Toledo Medical Center. Prior to the
beginning of the 2012/2013 competition seasons, athletes from the identified sites will, as
part of their pre-season physical exam requirements, perform measures of the SEBT and the
FMS before the first day of practice. The performance of the SEBT and the FMS are explained
in detail in the attached protocol. During the competition season, the number of practice
and competition person exposures, as well as the number of ankle injuries, will be recorded
by the ATC at each school. Injury incidence is explained in detail in the attached
protocol. At the end of the competition seasons, the rate of ankle injuries/exposure will be
calculated and compared with the pre-season SEBT scores to create a simple and a complex
prediction model for risk of ankle injury.
