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.
