Abstract:
Purpose:Mechanical and functional ankle instability or combinations of both can contribute to chronic ankle instability (CAI). Therefore, the purpose of this study was to compare the difference in (1) static and (2) dynamic balance function between patients with CAI and the controls; (3) to investigate association between balance function and CAI; and (4) to examine whether balance assessments are valuable for diagnosing CAI.
Methods:This study was conducted on 40 patients with CAI and 40 ankle healthy individuals. All participants evaluated the Cumberland Ankle Instability Tool questionnaire. Additionally, joint laxity and center of pressure (COP) during static postural control, anterior landing, and lateral landing were measured using an electronic pedobarography.
Results:CAI patients showed a larger COP area than controls when performing static postural control (p=0.023) and lateral landing (p=0.002). As a result of the receiver operation characteristic curve analysis, COP distance, area, and speed during static postural control and COP area during lateral landing showed low accuracy, indicating that they are valuable evaluations for the diagnosis of CAI.
Conclusion:Patients with CAI had poor static and dynamic postural control ability. The static posture control and the lateral landing test had diagnostic significance to evaluate the objective function of CAI.
