Sound touch viscosity in the evaluation of median nerve in healthy volunteers-a preliminary study.

ABSTRACT:

Background

Quantitative assessment of peripheral nerve viscoelasticity is important for understanding nerve physiology and detecting early neuropathic changes. However, reference values for the viscosity and stiffness of the median nerve in healthy adults are lacking.

Materials and methods

A total of 98 healthy volunteers (58 females, 40 males; mean age: 35 ± 12 years) were assessed using the Sound Touch Viscosity and shear wave elastography modules integrated into the Resona A20S ultrasound system. Viscosity and stiffness were measured at three anatomical locations: the carpal tunnel (MN1), mid-forearm (MN2), and 5 cm proximal to the elbow joint (MN3). Paired bilateral measurements were obtained, and demographic factors were analyzed for their influence.
