The aim of this study was to investigate the effect of balance disc exercise on postural stabilization and dynamic balance. Twenty healthy female university students who were not in a regular exercise program participated in the study voluntarily. The women were divided into two groups as exercise (10 women) and control groups (10 women). Exercise group participated in balance exercise program by using vestibular balance disc for 6 weeks, 3 sessions a week which lasted for 50 minutes. Lunge distance, multiple single-leg hop stabilization error and star excursion balance test distance were measured before and after 6-week exercise program. The control group did not participate in the exercise program. The data were analyzed using The Mann Whitney U and Wilcoxon test. The results showed that there was significant difference between before and post exercise lunge test distances in exercise group (p 0.05). There were significant differences in forward lunge with right and left leg distance between exercise group and the control group (p 0.05). There was significant difference in right and left leg landing errors between exercise and control group (p 0.05). There were significant differences in anterior, anteromedial, medial, anterolateral distance in right leg and anterior, anteromedial, medial, posterolateral, lateral and anterolateral distance in left leg between exercise group and the control group (p<0.05). As a result, 6 week balance exercise with balance disc affects dynamic balance and postural stability positively
