40-yard Run Times, Ankle Injury, Joint Mobilizations


Physical Therapy | Rehabilitation and Therapy | Sports Sciences


Ankle sprains are one of the most common injuries sustained among all people, especially those within the athletic population. More specifically, inversion ankle sprains are much more common than eversion ankle sprains. In fact, it has been reported that lateral ligament sprains make up approximately 80-95% of all ankle sprains. For this reason, it is important to examine the predisposing factors that may increase the likelihood of ankle sprains and as well as the effects ankle sprains have on ankle joint stability.

A significant amount of research has been dedicated to ankle injuries and the effects on functional performance as well as joint mobilizations and the effects on range of motion and pain. However, the possibility of improving functional performance of ankle injured individuals with the application of joint mobilizations has not been sufficiently examined in the literature. Therefore, the purpose of this study is to examine if functional performance, as measured by a 40 yard sprint, is improved with the application of joint mobilization treatments in ankle injured individuals.
