Objective: To explore the value of neural electrophysiological examination in the diagnosis and treatment evaluation of carpal tunnel syndrome (CTS). Methods: We recruited 165 cases with CTS (204 affected sides) treated in the Department of Orthopaedics and Trauma of Peking University People's Hospital, Peking, China, between March 2004 and November 2013. We included 68 cases (88 sides) in the study according to the defined inclusion criteria. Following a definitive diagnosis, all 68 patients were treated with median neurolysis. The Boston Carpal Tunnel Questionnaire was administered by telephone as a follow-up after surgery. Results: The median nerve motor latency, motor nerve compound muscle action potential, sensory nerve conduction velocity, and sensory nerve action potential, showed a specificity of diagnosis of 63.6%, 43.2%, 88.6% and 61.4%, respectively. There was a correlation between patients' preoperative neural electrophysiological examination indexes and BCTQ scores before and after surgery. Conclusion: Neural electrophysiological examination is an objective and effective auxiliary examination for diagnosing CTS. The positive diagnosis rate of neural electrophysiological examination indexes is high in patients with CTS. To some extent, neural electrophysiological examination indexes can be used to evaluate patients' preoperative symptoms and functioning, and have a certain predictive function for prognosis of the disease.
