The objective of the study was to find out the effect of wobble board training program on balance in athletes with Functional Ankle Instability (FAI). A total of 30 subjects (n=30) with FAI were recruited based on the set inclusion and exclusion criteria. All the subjects were evaluated for balance using single limb stance test and functional reach test and they were subjected to wobble board training program for five sessions in a week for four weeks. Paired sample t test was used to compare the mean between the pre and post test data’s and the level of significance was set at level of 0.05. In single limb stance test, the athletes scored high post training score mean value [26.4] than pre training score [9.73]. Thus the difference is statistically confirmed by the obtained‘t’ value [16.00]. In functional reach test, the athletes scored high post training score mean value [15.88] than pre training score (14.26). Thus the difference was statistically confirmed by the obtained‘t’ value [12.54]. This indicated that wobble board training promoted the static and dynamic balance in athletes with functionally unstable ankle. Hence, it can be concluded that wobble board training might be effective in improving balance among athletes with functionally unstable ankle.
