There is current need for objective measures of sciatic nerve mobility in patients with sciatic-type pain. The objective of the study was to assess the feasibility and reliability of ultrasound elastography to quantify sciatic nerve displacement and shear strain at the sciatic nerve-hamstring muscle interface during active and passive knee extension-flexion exercises performed while sitting in healthy people. Ultrasound elastography showed excellent intrarater within-session reliability for assessing sciatic nerve displacement and sciatic nerve-hamstring muscle interface shear strain during active knee extension-flexion exercises. These findings will inform similar future work conducted in patients with sciatic-type pain.
目前需要对坐骨神经型疼痛患者的坐骨神经活动度进行客观测量。本研究的目的是评估超声弹性成像在健康人坐位进行主动和被动膝关节屈伸运动时，量化坐骨神经-腘绳肌界面处坐骨神经位移和剪切应变的可行性和可靠性。超声弹性成像显示，在主动膝关节屈伸运动期间，评估坐骨神经位移和坐骨神经-腘绳肌界面剪切应变时，组内观察者间信度极佳。这些发现将为未来对坐骨神经型疼痛患者开展的类似研究提供参考。
