Clinical Examination Results in Individuals With Functional Ankle Instability and Ankle-Sprain Copers

Document Type


Publication Date



The aim of this study is to contrast individuals with functional ankle instability (FAI), copers, and uninjured individuals on both self-reported variables and clinical examination findings. Self-reported disability was recorded using the Cumberland Ankle Instability Tool and Foot and Ankle Ability Measure for Activities of Daily Living and for Sports. On clinical examination, ligamentous laxity and tenderness, range of motion (ROM), and pain at end ROM were recorded. Individuals with FAI had greater self-reported disability for all measures (P < .05). On clinical examination, individuals with FAI were more likely to have greater talar tilt laxity, pain withinversion, and limited sagittal-plane ROM than copers (P < .05). Differences in both self-reported disability and clinical examinationvariables distinguished individuals with FAI from copers at least 1 year after injury. Whether the deficits could be detected immediately postinjury to prospectively identify potential copers is unknown.
