The purpose of this study was to investigate the effect of kinesiotape on the electromyographic activity of selected lower limb muscles of athletes with and without chronic ankle instability during balance tests. The activity of tibialis anterior, proneous longus, gastrocnemius medialis and lateralis, soleus, vastus medialis and lateralis and biceps femoris muscles in 12 athletes with chronic ankle instability and 12 healthy athletes during leg stance time and star excursion balance tests to check the level of activity and co-contraction recordrd. Analysis of variance tests with repeated measurements was used to investigate within and between group effects. Findings showed the kinesiotape did not have any significant effect on the level of activity and the co-contraction ratio during the leg stance time test, and there wasn’t also any significant difference between the two groups in the level of activity and the co-contraction ratio during leg stance time test (p˃0.05). In contrast, kensiotype had a significant effect on the co-contraction ratio during the star excursion balance test, but the results between the two groups were not significant (F=2.27, P=0.14). Considering the effect of kensiotype on the co-contraction ratio of muscles during the performance of the star excursion balance test, it is suggested to use it to improve dynamic balance.
