半膜肌腱是膝关节重要的动态后内侧稳定器，主要在膝关节屈曲（后斜韧带松弛）和内旋期间发挥作用。 在外侧，股二头肌的短头和长头形成一根附着在腓骨头上的单根肌腱，包围外侧副韧带的远端插入。 1 检查位置及探头. 患者处于 俯卧 位，双脚悬在桌子边缘。 通常使用 6–10MHz探头，但在检查肥胖或肌肉发达的患者时，建议使用较低的频率，特别是在坐骨结节的起源区域。 2 研究区域. 腘绳肌的超声检查看起来像一个 倒置的音叉，用特定的标志标记了四个关键区域（图3）。

2023年10月1日 · The biceps femoris long head (BFLH) gains its properties from internal elements (fascicles and tendinous tissues) which behaviors remain poorly understood across BFLH regions and dynamic tasks. The aim of this study was to assess the in vivo behaviors of fascicles and tendinous tissue in the proximal and distal regions of BFLH during different ...

Hamstring strains, particularly involving the long head of biceps femoris (BFlh) at the proximal musculotendinous junction (MTJ), are commonly experienced by athletes. With the use of diagnostic ultrasound increasing, an in-depth knowledge of normal ultrasonographic anatomy is fundamental to better …

股二头肌短头 (BFsh) 表现出最小的应变、AP 和 ML 变形。 此外，BFlh 显示出最高的刚度和应力，而 BFsh 具有最低的应力。 此外，变形因区域而异，近端部位通常显示出最低的 CSA 应变。 在膝关节等长屈曲期间，腘绳肌的远端肌腱机械特性有所不同。 与其他双关节腘绳肌相比，BFlh 的高硬度和应力可能会导致在短跑后期摆动期间，其肌肉束而不是远端肌腱吸收更多的能量。 这可以部分解释该肌肉腿筋损伤发生率增加的原因。 Tendon properties impact human locomotion, …

2024年9月1日 · The ground reaction force (GRF), 3D lower limb kinematics, EMG, and ultrasound images of biceps femoris long head (BFlh) in the middle region were recorded simultaneously. BFlh fascicles undergo little length change (about 1 cm) in the late swing phase during running at three submaximal speeds.

This study aimed to investigate the changes in fascicle length (Lf) of biceps femoris long head (BFlh) after 10 d of bed rest (BR) by comparing four different ultrasound (US) methods. Methods Ten healthy men participated in 10-d BR.

Objectives: Hamstring strain injuries (HSIs) commonly affect the proximal biceps femoris long head (BFlh) musculotendinous junction. Biomechanical modeling suggests narrow proximal BFlh aponeuroses and large muscle-to-aponeurosis width ratios increase localized tissue strains and presumably risk of HSI.
