title: [Sensorimotor Deficits in Functional Ankle Instability].
abstract: Lateral ankle sprains are among the most common sports injuries, with a prevalence of 25 to 30 % of all injuries. At least one-third of individuals develop long-term complaints and chronic instabilities at the ankle, which in many cases cannot be attributed to mechanical insufficiencies of the joint. This condition is referred to as functional ankle instability (FAI). Impairments of the sensorimotor control system, such as disturbed proprioception and postural control, as well as reduced muscle strength and reflex activity, have been suggested to contribute to the aetiology of FAI. This review summarises the current body of literature regarding sensorimotor control in individuals with FAI. We discuss the results in the context of current neurophysiological models of the development of functional joint instabilities.
