Abstract

Abstract: Objective: The purpose of this study was to investigate the association between Cumberland Ankle Instability Tool (CAIT) scores and postural stability during a diagonal landing, and to investigate whether postural stability is altered in collegiate soccer players with and without functional ankle instability (FAI). Design: Cross-sectional study. Setting: Laboratory. Participants: Ninety-one soccer players were classified into a FAI group (history of at least two ankle sprains and a CAIT-Japanese version score ≤25, n = 28), a copers group (history of one ankle sprain and a CAIT-Japanese version score ≥26, n = 32), or a control group (no history of ankle sprain, n = 31). Main outcome measures: Time to anteroposterior stabilisation (TTSAP) and mediolateral stabilisation (TTSML) were measured during the diagonal single-leg landing. Results: The CAIT scores were correlated with TTSAP ( P < 0.05, r s = −0.214) and TTSML ( P < 0.01, r s = −0.566). TTSAP was longer in the FAI group than in the control group, and TTSML was longer in the FAI group than in the other groups. Conclusions: Our findings indicate the presence of an association between the CAIT-J score and TTSML, as well as postural stability deficits in collegiate soccer players with FAI during diagonal landings. Highlights: Implications for Rehabilitation. CAIT might be useful for assessing FAI related to postural stability. CATI scores likely associate more with TTSML than TTSAP during diagonal landings. A soccer player with feelings of ankle instability might have impaired postural stability.
