Abstract

Chronic anke instability (CAI) is characterised by feelings of giving way and/or instability surrounding the ankle joint following an initial ankle sprain [1]. Many factors are thought to contribute to CAI including altered regulation of Ia-afferent activity; however, this has only been investigated during isometric tasks [2, 3]. The functional significance of altered Ia-afferent regulation in CAI remains unclear. The first aim of this study was to examine if regulation of Ia-afferent excitability at ground contact of a landing task is different between persons with CAI and healthy controls. A secondary aim was to identify how, if at all, any identified changes in Ia-afferent excitability relate to postural stability.
