Effects of kinesio tape on kinesiophobia, balance and functional performance of athletes with post anterior cruciate ligament reconstruction: a pilot clinical trial

Background Anterior cruciate ligament trauma is one of the most common knee injuries in professional athletes. This study aimed to investigate the effects of kinesio taping on kinesiophobia, balance, and functional performance in athletes after anterior cruciate ligament reconstruction. Methods This randomized, placebo-controlled clinical trial was performed on 20 athletes with anterior cruciate ligament reconstruction (mean age 32.3 ± 6.2 years) at the time of return to sport. The subjects were randomly assigned to the kinesio tape (KT) group (n = 10) or placebo KT group (n = 10). While subjects under taped, the following outcomes were measured at baseline, 10 minutes after the intervention, and 2 days later. Kinesiophobia, balance, strength, and functional / agility performance were assessed by the Tampa Scale, Y balance test (YBT), single-leg hops, and 10-yard extremity functional test, respectively. Results The results did not show a significant difference between-group post-intervention differences in kinesiophobia (Mean between-group difference = − 6.30, 95% CI = − 4.35 to 1.42, P-value = 0.17). Likewise, no significant statistical difference was observed between two study groups in terms of YBT scores (Mean between-group difference ranged over = − 6.30, 95% CI = − 1.1 to 4.7, the effect sizes ranged over = 0.01 to 0.31), P-value > 0.05), Single Leg Hop (Mean between-group difference = − 0.48, 95% CI for difference ranged over = − 10.3 to 9.3, effect size = 0.001, P-value = 0.918), and 10 Yard test scores (Mean between-group difference = − 0.30, 95% CI = (− 1.3 to 0.75), effect size = 0.02, P-value = 0.55) at 2 days after the KT. In the KT and placebo KT groups, RMANOVA indicated that the differences in all variables scores were significant over time with large effect sizes (effect size ranged over = 0.94–0.99; all P-value Conclusion This study gives no support for any beneficial effect of kinesio taping on the reduction of kinesiophobi or improvement of balance score and functional performance in athletes with post anterior cruciate ligament reconstruction.
