Ankle sprain is one of the most common injuries among the athletes. Recurrence rate of this injury is about 70%. 85% of all ankle sprains are lateral ankle sprains. According to some reports 74% of patients with ankle sprain would have some symptoms which are known as chronic ankle instability. Today virtual rehabilitation systems are used to improve patients motivation and their engagements in therapy sessions and also to get better results of interventions. Virtual reality system provide the ability of controlling duration and intensity of interventions and the environment modification. In our study 30 patients with chronic ankle instability will be allocated to 3 groups of 1:regular training 2:training with virtual reality system using Nintendo Wii balance board and 3:control group. 10 sessions of training in 3 weeks are designed for two groups of interventions. Patients balance will be measured 3 times: 1-before 1st session 2-after 5th session 3-after the last session
