Background: To evaluate patients with chronic ankle instability (CAI), copers who had a sprain without instability, and 
healthy controls using the Star Excursion Balance Test (SEBT). In addition, the reach distance was assessed between 
the both legs in terms of dominant and non-dominant in all groups.
Methods: A total of 75 subjects (25 healthy, 25 CAI, and 25 Coper) participated. The maximum reach distance in SEBT 
was assessed in anterior (ANT), postero-medial (PM), and postero-lateral (PL) directions in both legs for each subject. 
All data were analyzed by SPSS version 21. Tukey post hoc test was used to compare all groups. Paired T-test was 
used to compare dominant and non-dominant legs in each group. 
Results: In 75 subjects have participated in the data collection, no significant differences were reported among all 
groups for age and BMI measurements. Significant lower reach distance in scores of ANT in the dominant leg of the CAI 
was demonstrated when compared with the control and the coper groups (P=0.008). No statistical significant difference 
was determined between the dominant and non-dominant legs in each group (P>0.05). 
Conclusion:It seems that relevant strategies for postural control should be taken into account in the rehabilitation 
setup of individuals with CAI.
