Abstract

Objectives: To present some of the current concepts that form a comprehensive model of sensory-motor control impairment in functionally instable ankle. Methods: A literature search of journal articles in English was conducted using the PubMed database from inception to 201 1 and relevant studies dealing with sensory-motor factors associated with human ankle stability were identified. Results: Findings from individual studies on the role of sensory-motor function in ankle stability yield to conflicting conclusions. The current body of literature as well as recent systematic reviews quite unanimously show: (1) an immediate impairment in ankle proprioception after ankle ligament injury, without any direct evidence of a local mechanoreceptor deficit: (2) no con\istent experimental evidence of impairment in mu5cle reaction time and in muscle strength associated with functional instable ankle: (3) evidence of a bilateral response pattern, at both the ankle and proximal joints, after unilateral foot and leg displacement; (4) the occurrence of a bilateral impairment of postural and balance control. following unilateral injury.
