Running-related knee injuries are associated with high and repetitive quadriceps contractions. Infrapatellar straps are commonly recommended for the prevention and management of those injuries. The effects of infrapatellar straps have been investigated in terms of quadriceps activations. However, these indexes cannot accurately characterize the quadriceps forces, which directly contribute to knee injuries. This study aimed to quantify quadriceps forces during running performed with and without infrapatellar straps based on OpenSim. Experimental data from 18 healthy participants were recorded using a 10-camera motion capture system and two force plates when they performed running at self-selected speeds with and without infrapatellar straps. OpenSim was used to estimate muscle forces, muscle activity, joint kinematics, and joint kinetics. The use of infrapatellar straps significantly reduced peak quadriceps forces (p < 0.001), accumulated forces of quadriceps (p < 0.001), and peak knee extension moments (p < 0.001). Among the four distinct muscles of the quadriceps, the vastus lateralis contributed the most to the reduction in quadriceps muscle forces. Strapping did not result in a significant change in rectus femoris forces (p > 0.05). The use of infrapatellar straps results in lower vastus muscle forces, and thus could be helpful in managing and preventing running-related knee injuries. However, infrapatellar straps may have little effect in people with an excessively forceful rectus femoris.
与跑步相关的膝伤与股四头肌的高强度反复收缩有关。髌下带通常被推荐用于预防和处理这些损伤。人们已从股四头肌激活的角度对髌下带的效果进行了研究。然而，这些指标无法准确表征直接导致膝伤的股四头肌力量。本研究旨在基于OpenSim量化佩戴和不佩戴髌下带跑步时的股四头肌力量。18名健康参与者在佩戴和不佩戴髌下带以自定速度跑步时，使用10台摄像机的运动捕捉系统和两块测力板记录实验数据。利用OpenSim估算肌肉力量、肌肉活动、关节运动学和关节动力学。佩戴髌下带可显著降低股四头肌峰值力量（p < 0.001）、股四头肌累积力量（p < 0.001）以及膝关节伸展峰值力矩（p < 0.001）。在股四头肌的四块不同肌肉中，股外侧肌对股四头肌力量降低的贡献最大。绑扎对股直肌力量没有显著影响（p > 0.05）。佩戴髌下带会使股肌力量降低，因此可能有助于处理和预防与跑步相关的膝伤。然而，髌下带对股直肌力量过大的人可能效果甚微。
