Immediate effect of ACL kinesio taping technique on knee joint biomechanics during a drop vertical jump: a randomized crossover controlled trial

摘要

The purpose of this study was to investigate the effect of an ACL Kinesio Taping technique (ACL-KT) on knee joint biomechanics during a drop vertical jump (DVJ). Twenty healthy male participants (age 21.1±0.3 years; mass 64.2±4.3 kg; height 174.2±5.5 cm) participated in this study. The participants performed a DVJ and landed onto 2 adjacent force platforms under both ACL-KT and placebo (PT) conditions. All data were collected with 3-D motion analysis and comparison peak knee joint angles and moments, and knee joint angle at initial contact (IC) between conditions analyzed using a paired sample t-test. Statistical parametric mapping (SPM) was selected to assess difference between groups for the entire three-component knee trajectory during the contact phase. ACL-KT had a significant effect on decreasing knee abduction angle at IC (1.43±2.12 deg.) compared with the PT (?1.24±2.42 deg.) (p=0.04). A significant difference in knee abduction angle between the taping conditions was found between 100 ms before IC, at IC and 100 ms after IC (p0.05). There were no significant differences (p0.05) found between conditions in any of the other variables. This result confirmed that the application of ACL-KT is useful to reduce knee abduction angle at IC during a DVJ in healthy participants. Therefore, ACL-KT may be an acceptable intervention to reduce ACL injury risk.
