Association Between Neuroelectrophysiological Findings and Ultrasound Imaging Markers in Patients with Carpal Tunnel Syndrome
Objective To investigate the difference of ultrasound images in mild,moderate and severe neuroelectrophysiological manifestations of carpal tunnel syndrome(CTS).Methods A total of 90 patients with CTS who were treated in Zhengzhou Orthopaedic Hospital from October 2020 to September 2021 were selected as the study subjects and used as the case group.During the same period,113 non-CTS patients who underwent physical examination in hospital were selected as control group.Neuroelectrophysiological examination and high-frequency ultrasound examination were performed on the cases included in the study.Through the comparison of the two examination methods,the differences in the ultrasonic imaging manifestations of mild,moderate and severe neuroelectrophysiological manifestations of carpal tunnel syndrome were analyzed.Results Both sensory latency and terminal motor latency were strongly correlated with median nerve swelling rate in electrophysiological examination(r≥0.837),while sensory conduction velocity was negatively correlated with shear wave velocity(r=-0.816).With the exacerbation of CTS,the median nerve cross-sectional area,flattening rate,swelling rate and shear wave value all increased.There was no significant difference in median nerve cross-sectional area and swelling rate between mild patients and normal group,and no significant difference in shear wave velocity between moderate and severe patients(P＞0.05).Conclusion Patients with mild,moderate and severe neuroelectrophysiological manifestations of carpal tunnel syndrome have significant differences in ultrasound imaging.The results of this study can provide certain reference value for the diagnosis and treatment of carpal tunnel syndrome.
