Structural and dynamic characteristics in sonographic evaluation of the sciatic nerve in patients with probable neuropathic pain - A cross-sectional study.

Introduction: Structural and dynamic alterations of peripheral nerves are commonly observed in patients with radiculopathy. The current study aimed to compare the cross-sectional area (CSA), echogenicity index (ECHO), and skin-to-nerve distance (SKN) of the sciatic nerve between the symptomatic and asymptomatic sides of patients with probable neuropathic pain under different levels of nerve tension.

Methods: A cross-sectional study was conducted with 31 participants classified as having probable chronic neuropathic pain.
