Abstract

Objective: We analyzed some clinical and electrophysiological characteristics of median nerve lesions in carpal tunnel syndrome (CTS). Subjects and methods: We studied 111 CTS from January 2022 to April 2023 at the Neuroelectrophysiology Room, Dong Do General Clinic, Hanoi. Results: The average age of the patients was 52.2 ± 9.71; women accounted for 88.3%. The average duration of the disease is 19.3 ± 25.59 months. Symptoms include numbness and decreased sensation at 94.6%, nocturnal paresthesia at 73%, and thenar atrophy at 3.6%. Tinel and Phalen signs were positive at 40.5% and 47.7%, respectively. The prolongation of the difference between the median latency of the median nerve and ulnar nerve accounted for 96.6%, followed by MUD with 92.3%. The clinical CTS severity correlated linearly with the electrophysiological severity (p=0.003<0.05; r = 0.279). The severe severity of patients' CTS accounted for 62.2% according to Werner's electromyographic grading of patients, which was higher than the clinical grading (23.4%). Conclusion: The severity of CTS between clinical and electromyography is correlated and the severity of CTS is electrodiagnosed earlier than clinically.
