N2  -  Summary. Background. Chronic ankle instability (CAI) could be a common consequence of one or multiple ankle sprains and may lead to long-term functional impairments. In literature, most studies have investigated these impairments using only a single functional task, while few have employed a comprehensive battery of tests. The purpose of this study was to detect correlations between functional ability, activity level and perceived ankle status to find out differences between patients affected by CAI and healthy subjects using a jump test battery. Methods. 42 subjects ranging in age from 18 to 45 were included in the present study. A group of 21 patients with CAI was matched for number age, sex, and body mass index to a control group of healthy volunteers with no history of lower limb pathology. The American Orthopaedic Foot & Ankle Society ankle-hindfoot scale (AOFAS), and Tegner activity level were determined for all subjects. An OptoGait (Microgate, Bolzano, Italy) infrared sensor device was used to measure jumping performance. The test battery included countermovement jumps (CMJs), drop jumps (DJs), side-hop tests. Results. A significant difference (lower in CAI patients) in both AOFAS and Tegner scores between healthy individuals and CAI patients (p<0.001 and p<0.01, respectively) was observed and weak to moderate positive correlation was found for both CMJ and DJ and point scales in CAI patients (p<0.01). Conclusions. In healthy individuals, jumping performance appears to depend on overall physical activity, whereas in CAI patients it is more closely associated with both perceived ankle function and objective impairments. Our findings support the recommendation to combine patient-reported outcomes and functional performance tests in the clinical assessment and management of CAI.
