Chronic ankle instability in sporting populations.

Background: Chronic ankle instability (CAI) is a term used to identify certain insufficiencies of the ankle joint complex following an acute ankle injury. Acute ankle injuries are often associated with sporting mishaps; however, this review was the first to identify the aspects of CAI (perceived instability, mechanical instability and recurrent sprain), and persisting symptoms following an ankle sprain, that have been reported within sporting cohorts.

Objective: To determine the presence of common aspects of CAI within individual sports.
