Attentional Demands and Postural Control in Athletes With and Without Functional Ankle Instability

Subjects with FAI demonstrated poorer postural stability when tested at level 5 on the Biodex Stability System, but not at level 7. Also, the results indicate that concurrent performance of a cognitive task decreased postural stability in the subjects with FAI, suggesting an increased dependency on attentional demands for maintenance of balance in that group. Such findings highlight the need for the assessment of postural control in patients with ankle sprain to include cognitive loading.
