膝关节损伤经常发生在进行体育活动的个体中。研究发现，膝关节绷带可以减轻膝关节韧带的负担，尤其是髌骨肌腱。然而，方法的定量验证的动力学效果的胶带上的髌腱是有限的。在这项研究中，开发了一种使用超声成像的测量方法来量化膝关节贴扎对髌腱的影响，并在健康受试者中验证了这种影响。实验在五种条件下进行：膝关节上不贴胶带和四种不同的贴胶带方法。为了验证在五个实验条件下的髌腱上的贴扎效果的差异，我们从使用超声成像获得的髌腱的横截面积和伸长率计算应力-应变曲线。12名健康男性（年龄22.6 ± 1.1岁）参加了实验。要求每个受试者坐在椅子上，膝关节屈曲90 °，伸展膝关节，并保持伸展力3 s。在最后一次等长收缩时，将伸展力从40、80、120、160 N改变为每个受试者的最大随意伸展力。成功地测量了髌腱在膝关节包绕状态下的弹性模量。无包胶条件下的应力-应变曲线与所有四种包胶条件下的应力-应变曲线有显著差异（p <0.05）。
Knee joint injuries frequently occur in individuals performing sport activities. Knee taping is found to reduce the burden on knee ligaments, particularly the patellar tendon. However, methods for quantitative verification of the kinetic effects of taping on the patellar tendon are limited. In this study, a measurement method using ultrasound imaging was developed to quantify the effects of knee taping on the patellar tendon, and the effects were verified in healthy subjects. The experiment was conducted under five conditions: no taping on the knee joint and taping by four different methods. To verify the differences in taping effect on the patellar tendon under five experimental conditions, we calculated the stress-strain curve from the cross-sectional area and elongation of the patellar tendon acquired using ultrasound imaging. Twelve healthy men (aged 22.6±1.1 years) participated in the experiment. Each subject was asked to sit on a chair with the knee joint flexed at 90, extend the knee joint, and maintain the extension force for 3 s. During the last isometric contraction, the extension force was changed from 40, 80, 120, 160N to the maximum voluntary extension force of each subject. We succeeded to measure the elastic modulus of the patellar tendon under knee taping condition. The stress-strain curve under no taping condition was significantly different from all four taping conditions (p< 0.05).
