背景:膝关节损伤可能是由于股四头肌肌力受损或膝关节本体感觉减弱所致。将Kinesio胶带(KT)从起源到插入(OTI-KT)或插入起源(ITO-KT)对股四头肌的应用可能会影响膝关节本体感觉和股四头肌的力量。本研究旨在评估不同张力和KT应用方向对健康男性股四头肌主动和被动膝关节复位误差(AJRE和PJRE)以及峰值同心和偏心峰值扭矩(CPT和EPT)的影响。
方法:21名健康男性参与了这项重复测量研究设计。CPT,EPT,JJRE,用Biodex测功机在0%的OTI-KT前后测量优势肢的PJRE,15%,和40%的额外张力和ITO-KT与0%的张力。
结果:ITO-KT显示AJRE的显着降低(p<0.05)。同时,对于OTI-KT,在AJRE和PJRE有关时间(AJRE为F1,126=19.74,p<0.05;PJRE为F1,126=9.96,p<0.05)和张力(AJRE为F2,126=22.14,p<0.05;F2,126=20.67,PJRE为p<0.05)方面观察到统计学上的显着差异。
结论:应用KT,尤其是具有40%和15%额外张力的OTIKT,显示出增强膝关节本体感觉的潜力,而不会立即影响股四头肌的扭矩。这表明在运动表现和膝关节损伤康复中的应用。
BACKGROUND: Knee joint injuries may result from compromised quadriceps muscle strength or diminished knee joint proprioception. The application of Kinesio tape (KT) on the quadriceps muscle from origin to insertion (OTI-KT) or insertion to origin (ITO-KT) could impact knee joint proprioception and quadriceps muscle strength. This study aims to assess the effects of different tensions and directions of KT application on active and passive knee joint repositioning errors (AJRE and PJRE) and peak concentric and eccentric peak torque (CPT and EPT) of the quadriceps muscles in healthy males.
METHODS: Twenty-one healthy males participated in this repeated-measures study design. CPT, EPT, AJRE, and PJRE of the dominant limb were measured by a Biodex dynamometer before and after applying OTI-KT with 0%, 15%, and 40% extra tensions and ITO-KT with 0% tension.
RESULTS: ITO-KT demonstrated a significant reduction in AJRE (p < 0.05). Meanwhile, for OTI-KT, a statistically significant difference was observed in both AJRE and PJRE concerning time (F1,126 = 19.74, p < 0.05 for AJRE; F1,126 = 9.96, p < 0.05 for PJRE) and tension (F2,126 = 22.14, p < 0.05 for AJRE; F2,126 = 20.67, p < 0.05 for PJRE).
CONCLUSIONS: Applying KT, especially OTI KT with 40% and 15% extra tension, shows potential in enhancing knee proprioception without immediate impacts on quadriceps muscle torque. This suggests applications in sports performance and knee injury rehabilitation.
