The Biodex balance system was utilized to assess postural balance as overall stability, anterior-posterior and mediolateral stability indices in open and blind conditions on dominant limb. The K-S test has been used to examine the normality of distribution, while the independent T for comparing the target groups. Results: There was a significant difference between two groups in the open situation only for the overall stability index (P M3 ER -
