Background & aim: Studies have shown that ankle sprain injury effects on balance of affected individuals. The changes in the postural control and activity of the ankle muscle, because of ankle sprain, can put the patients at reinjure risk and lower extremity injuries, especially during dynamic activities. The purpose of the study was to investigate the immediate effect of lower limb kinesiotype on static and dynamic postural control in athletes with chronic ankle instability. Methods: Twenty athletes with chronic ankle instability (11 male, 9 female) with 15-17 years old volunteered to participate in this study. Star excursion balance test and leg stance time were used for measuring static and dynamic postural control respectively. Measurements were taken at two different times: baseline or no tape, immediately after the taping application on ankle with chronic instability. Paired sample test was used for comparison pre-test and post-test. The level of significance (alpha) was set at 0.05. Results: finding indicated after using kinesiotape there is no significant effect in anterolateral and posteromedial directions of star excursion balance test (p ≥ 0.05). In contrast, there is significant effect in static postural control after using lower limb kinesiotype on ankle with chronic instability (p ≤ 0.05). Conclusion: Immediate use of kinesiotype can effect on ankle stability and increasing postural control in athletes with chronic ankle instability. Further studies, including a long-term follow-up assessment, are needed to evaluate the long-term benefits of kinesiotype. Also we suggest to further researchers investigate the effect of kinesiotype after activities related to sport on static and dynamic postural control.
