Chronic ankle instability has defined as recurrent ankle sprain, so that 40% of injured athletes after acute injury despite of receiving of adequate rehabilitation, suffering from this instability. The purpose of this study is investigate of postural sway’s risk factors proportion in jump-landing and lateral hopping tasks, in prediction of chronic ankle sprain occurrence. 25 ankle sprain injured athletes and 25 healthy athletes participated in this descriptive-analytic study. Six variables (area of sways, path length and velocity of sways in jump-landing and lateral hoping tasks) were measured as predictor variables, and we used to Logistic Regression test for predicting. The results of study showed that path length and velocity of sways in jump-landing, area and path length of sways in lateral hopping had statistical significant proportion in classification of injured and healthy groups, and the model classified about 77% cases correctly. Therefore, athletes with ankle sprain history have less control of posture than healthy subjects in jump-landing and hopping tasks and have higher risk to getting recurrent ankle sprain. Also subjects with chronic ankle sprain have less control of posture in frontal plan
