Carpal Tunnel Syndrome: Diagnostic Usefulness of Ultrasound Measurement of the Median Nerve Area and Quantitative Elastographic Measurement of the Median Nerve Stiffness

Abstract

To correlate the ultrasound (US) measurements of the median nerve cross‐sectional area (CSA) and the measurements of its stiffness by shear wave elastography (SWE) with the severity grade of carpal tunnel syndrome (CTS) using electrodiagnostic testing (EDT) and to determine the cutoff points for CSA and SWE measurements to allow us to discriminate patients with moderate and severe CTS from those with mild or negative EDT findings.
