Background: The use of Wii training for rehabilitation has received substantial attention in the last few years. It is effective in improving balance and functional performance. However, there are no previous studies investigating its effect on muscle strength and strength ratios. Purpose: The study was conducted to examine the effect of Wii training on ankle strength ratio in adults. Methods: Thirty two male healthy volunteers with mean age of 19.65 year participated in the study. They were randomly assigned into two equal groups (experimental and control). Participants in the experimental group performed Wii training program for six weeks. Data were collected using the Biodex Isokinetic system. Peak torque of dorsiflexors and planter flexors was measured at an angular velocity of 60{u00B0}\sec which in turn used to derive ankle dorsiflexion/plantarflexion strength ratio. Findings: 2x2 Mixed Design ANOVA revealed that the mean values of ankle dorsiflexion/ plantarflexion strength ratio were declined significantly (p<0.05) between the 2pre3 and 2post3 test records in the experimental group, meanwhile for the control group the difference between the "pre" and "post" test records was not significant (p>0.05). Interpretation: Wiihabilitation has an impact on ankle dorsiflexion/plantarflexion strength ratio. So, it can provide an effective tool in terms of muscular strength and ankle strength ratio. Thus, it could be recommended in both prevention and rehabilitation of patients with chronic ankle instability
