Relations between ultrasonographic, elastographic and electromyoneurographic parameters in patients with carpal tunnel syndrome

Introduction: To test the new proposed ultrasonographic (US) diagnostic algorithm for carpal tunnel syndrome (CTS) (Goldberg G, 2016), to compare cross-sectional area (CSA), wrist-to-forearm CSA ratio (WFR) and the elasticity of the median nerve (MN) between 2 groups: healthy volunteers and patients with electrodiagnostically proven CTS. Methods: 10 patients with CTS (20 hands) and 12 healthy volunteers (24 hands) underwent US of the MN. The CSA and MN strain was measured (MN strain was measured three times) by a radiologist (with 30 years of experience) and by medical resident. Examiners were blinded to the dia…
