Effects of kinesio taping on hip abductor muscle strength and electromyography activity in athletes with chronic ankle instability: A randomized controlled trial

Abstract

Objective: Athletes with chronic ankle instability tend to develop hip abductor muscle weakness. Kinesio taping may help this muscle perform its functions, thus preventing injury. The aim of this study was to assess the effects of Kinesio taping on hip abductor muscle strength and electromyography (EMG) activity. Subjects: A total of 34 athletes, mean age 22.08 years (standard deviation 2.71 years) participated in the study. Methods: A pre-test?post-test experimental design was used. For the experimental group, Kinesio tape, and for the control group, Micropore tape, was applied over the gluteus medius muscle. Gluteus medius muscle strength and EMG activity were noted in supine and during the single-leg squat test (SLST), respectively, before and after the intervention. Strength was measured through maximum voluntary isometric contraction (MVIC) force with a handheld dynamometer, and muscle activation measured through EMG. Results: In the experimental group, there was a significant increase in gluteus medius strength, by 10.27% (p?=?0.00), and a significant decrease in EMG activity (p?=?0.00), by 8.38%. In the control group, there was a significant increase in gluteus medius strength, by 2.89% (p?=?0.01) and a not statistically significant decrease in EMG activity, by 0.80% (p?=?0.15). Conclusion: Kinesio taping is effective in increasing hip abductor muscle strength in athletes with chronic ankle instability.
