PURPOSE
Estimation of muscle passive force from elasticity using shear wave elastography (SWE) has been reported. However, the relationship between the elasticity and passive force of human muscles has not been elucidated. This study investigated the elastic modulus-passive force relationship in human skeletal muscles at multiple sites.
METHODS
Four rectus femoris (RF) muscles were dissected from a human Thiel-embalmed cadaver. Calibration weights (0-600 g in 60-g increments) were applied to the distal tendon via a pulley system, and the shear elastic modulus as an index of elasticity was measured using SWE. The shear elastic modulus of the RF was measured at the proximal, central, and distal portions.
RESULTS
The results demonstrated that the relationships between the elasticity in the longitudinal direction of the muscle and the passive force were nearly linear for all tested sites, with coefficients of determination ranging from 0.813 to 0.993.
CONCLUSION
Shear wave elastography may be used as an indirect method to measure the changing passive force at any site within human muscles.
目的
已有研究报道，可通过剪切波弹性成像（SWE）从弹性估计肌肉的被动力。然而，人体肌肉的弹性和被动力之间的关系尚未阐明。本研究旨在探讨人体骨骼肌多个部位的弹性模量-被动力关系。
方法
从一具经过蒂尔（Thiel）防腐处理的人体尸体上解剖出 4 块股直肌（RF）。通过滑轮系统在远端肌腱上施加校准砝码（0-600g，增量为 60g），并用 SWE 测量作为弹性指标的剪切弹性模量。在 RF 的近端、中央和远端部分测量剪切弹性模量。
结果
结果表明，所有测试部位的肌肉纵向弹性与被动力之间的关系几乎呈线性关系，决定系数范围为 0.813 至 0.993。
结论
剪切波弹性成像（SWE）可作为一种间接方法，用于测量人体肌肉内任何部位的被动力变化。
