The ankle is the joint most affected among the sports‐related injuries. The current study investigated whether certain intrinsic factors could predict ankle sprains in active students. The 125 participants were submitted to a baseline assessment in a single session were then followed‐up for 52 weeks regarding the occurrence of sprain. The baseline assessment were performed in both ankles and included the questionnaire C umberland ankle instability tool – P ortuguese, the foot lift test, dorsiflexion range of motion, S tar E xcursion B alance T est ( SEBT ), the side recognition task, body mass index, and history of previous sprain. Two groups were used for analysis: one with those who suffered an ankle sprain and the other with those who did not suffer an ankle sprain. After C ox regression analysis, participants with history of previous sprain were twice as likely to suffer subsequent sprains [hazard ratio ( HR ) 2.21 and 95% confidence interval ( CI ) 1.07–4.57] and people with better performance on the SEBT in the postero‐lateral ( PL ) direction were less likely to suffer a sprain ( HR 0.96 and 95% CI 0.92–0.99). History of previous sprain was the strongest predictive factor and a weak performance on SEBT PL was also considered a predictive factor for ankle sprains.
