ABSTRACT
Background: The aim of this study is to identify the correlation between ultrasonographic findings of median nerve andclinical scale and electrophysiologic data in carpal tunnel syndrome.
Methods: Forty three patients (79 hands) with electrophysiologicallyconfirmed carpal tunnel syndrome were evaluated. Clinical symptoms were examined by Historical-Objective(Hi-Ob) scale. Electrophysiologic data and Padua scale were used for severity of electrophysiology. In ultrasonographic study,cross sectional area and flattening ratio of median nerve were measured at distal wrist crease level (DWC), 1cm proximalto distal wrist crease level, and 1cm distal to distal wrist crease level. The correlation between Hi-Ob scale, electrophysiologicdata and ultrasonography was measured with Spearman rank test.
Results: The mean Hi-Ob scale was 2.4. Mean Padua scalewas 4.0. In ultrasnonographic study, cross sectional area and flattening ratio were 0.112 cm2
Key words: Carpal tunnel syndrome, Ultrasonography, Electrodiagnosis, Clinical Scale
