Electrodiagnostic Studies in the Surgical Treatment of Carpal Tunnel Syndrome-A Systematic Review

The aim of our paper was to provide comprehensive data on the role of electrodiagnostic (EDX) studies in the surgical treatment of carpal tunnel syndrome (CTS). An extensive search was conducted through the major electronic database to identify eligible articles. Data extracted included grade of CTS based on neurophysiological testing, preoperative data of EDX studies, time of complete or partial resolution after surgery, postoperative Boston carpal tunnel questionnaire (CTQ) scores, age, sex, intraoperative and postoperative data of EDX studies, time to complete or partial resolution of symptoms, and number of patients without postsurgical improvement. Our main findings revealed that that electrodiagnostic testing is still a powerful tool for diagnosis of CTS. Moreover, it can also detect other pathologies. EDX testing provides a quantitative measure of the physiological function of the median nerve, which may be used to guide surgical treatment. Thirdly, when the outcome of surgery is unsatisfactory, NCS can assist in determining the reason for failure.

Automated summary

Electrodiagnostic testing plays a crucial role in the diagnosis and surgical treatment of CTS, providing a quantitative assessment of nerve physiological function. It can detect other pathologies and assist in determining reasons for surgical failure.
