The Effect of Kinesio Taping on the Feedforward Activity of the Lower Limb Muscles in Elite Volleyball Players With and Without Chronic Ankle Instability Performing Single-leg Jump-landing

Purpose: The current research aims to examine the effect of taping on the feedforward activity of the lower limb muscles in elite volleyball players with and without chronic ankle instability while performing single-leg jump-landing. Methods: The electromyographic activities of the lateral gastrocnemius, tibialis anterior, peroneus longus, rectus femoris, gluteus medius, and vastus lateralis of the non-dominant leg were registered before and after taping in 26 volleyball players while performing the spike skill with single-leg landing. These volleyball players entered the research by purposive sampling. The root mean square (RMS) was employed to compute muscle activity before and after taping. The multivariate analysis of variance (MANOVA) test at P≤0.05 was utilized to analyze the data. Results: The results of the multivariate analysis of variance (MANOVA) test demonstrated that the groups did not have a significant factor in any of the variables in the feedforward phase, except for the maximum root mean square (RMS) of the peroneus longus muscle (P=0.01). Conclusion: The results showed that taping cannot improve the feedforward activity of the selected muscles during single-leg landing in people with chronic ankle instability. Therefore, it is recommended to use other methods and exercises to improve the muscle feedforward activity in these individuals during the rehabilitation phases.
