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.
