Health-related quality of life is decreased in middle-aged adults with chronic ankle instability.
OBJECTIVES
The purpose of this study was to determine whether health-related quality of life and region-specific outcomes differ between middle-aged adults with and without chronic ankle instability.


DESIGN
Cross-sectional.


METHODS
Two hundred middle-aged individuals (40 years or older) volunteered to participate in the study. There were 75 individuals classified as having chronic ankle instability (51.5±7.3years, 175.8±3.7cm, 86.5±18.9kg) and 125 classified as not having chronic ankle instability (53.2±7.3years, 176.2±5.4cm, 81.3±17.6kg). Participants completed the Identification of Functional Ankle Instability as the inclusionary survey and the Internal Ankle Consortium guidelines were followed to classify individuals. Following the inclusionary survey participants completed the American Academy of Orthopaedic Surgeons Lower Limb Questionnaire and the Short Form-36 v2.


RESULTS
The Academy of Orthopaedic Surgeons Lower Limb Questionnaire, and the Physical Component Summary score of the Short Form-36 v2 were statistically different between groups (p<0.05). Specifically, the mean difference was 16.7 points and 12.3 points for the Academy of Orthopaedic Surgeons Lower Limb Questionnaire and the Physical Component Summary score, respectively, with the CAI participants scoring worse.


CONCLUSIONS
Individuals with CAI displayed decreased generic health-related quality of life and reduced region-specific ankle function.
