Background and Objective: Recurrent ankle sprains usually happen when a person does two or more tasks simultaneously. This study was aimed to investigate the effect of dual-task training (DTT) on dynamic postural control (DPC) in individuals with functional ankle instability (FAI). Method: This single-blind randomized controlled trial was conducted in Zahedan University of Medical Sciences in 2015. Thirty-two individuals with FAI were selected using a convenience sampling method and randomly assigned into two groups of Biodex balance training and DTT. Each group received its intervention for 4 weeks, three days a week, for 30 minutes per day. Overall stability index, anterior-posterior, and medial-lateral indices were measured by Biodex balance system in single and double-leg stances with open and closed eyes, before and after the intervention. Paired samples and independent t-tests were used for data analysis. Results: The results showed that overall stability, anterior-posterior, and medial-lateral stability indices improved significantly after performing DTT in all cases (P<0.05). In the balance training group, the medial-lateral stability index in a double-leg stance with open eyes at easy stability level and in double-leg stance with closed eyes at difficult stability level were significantly changed (P <0.05). However, in other cases, there were no significant changes (P<0.05). There were no differences between the two groups regarding the study variables (P<0.05). Conclusion: Dual-task training improved more balance indices compared to Biodex balance training. Hence, it is recommended that DTT be included in a physiotherapy program for people with FAI‎‎.
