INTRODUCTION
Evaluation of nerve mechanical properties has the potential to improve assessment of nerve impairment. Shear wave velocity, as measured by using shear wave (SW) ultrasound elastography, is a promising indicator of nerve mechanical properties such as stiffness. However, elucidation of external factors that influence SW velocity, particularly nerve tension, is required for accurate interpretations.
METHODS
Median and ulnar nerve SW velocities were measured at proximal and distal locations with limb positions that indirectly altered nerve tension.
RESULTS
Shear wave velocity was greater at proximal and distal locations for limb positions that induced greater tension in the median (mean increase proximal 89.3%, distal 64%) and ulnar (mean increase proximal 91.1%, distal 37.4%) nerves.
DISCUSSION
Due to the influence of nerve tension when SW ultrasound elastography is used, careful consideration must be given to limb positioning.
简介
评估神经机械特性有可能改善神经损伤的评估。剪切波速度（SW）超声弹性成像测量的剪切波速度是神经机械特性（如硬度）的一个有前途的指标。然而，需要阐明影响 SW 速度的外部因素，特别是神经张力，以进行准确的解释。
方法
在间接改变神经张力的肢体位置下，测量正中神经和尺神经的 SW 速度在近端和远端位置。
结果
在引起正中神经（近端增加 89.3%，远端增加 64%）和尺神经（近端增加 91.1%，远端增加 37.4%）张力更大的肢体位置下，SW 速度在近端和远端位置更大。
讨论
由于在使用 SW 超声弹性成像时神经张力的影响，必须仔细考虑肢体位置。
