Lateral ankle sprains are the most common injury in athletics (Denegar & Miller, 2002; Ekstrand & Tropp, 1990). In addition, the recurrent rate of ankle sprains is as high as 80% (Smith & Reischl, 1986). Repetitive ankle sprains may lead to a phenomenon known as chronic ankle instability (Hertel, 2002). It has been theorized that there are two main attributions to chronic ankle instability: mechanical and functional instability (Monaghan, Delahunt, & Caulfield, 2006). The exact mechanism of chronic ankle instability is still unclear; however, recent studies focus on multiple factors rather than single measurements, in addition to functional testing. A few studies showed the validity of the use of functional movement screen to predict injury risk (Kiesel, Plisky, & Butler, 2007; Chorba, Bouilon, Overmyer, & Landis, 2010), however there is limited research concerning past injury history and movement impairment. Therefore it was the purpose of this study to use functional movement screen to determine if participants with chronic ankle instability exhibit notable functional movement impairments when compared to a group of matched control with no lower extremity injury history.
