Developments in The Electrodiagnostic Assessment Of Carpal Tunnel Syndrome

Abstract

A systematic approach to the electrodiagnostic assessment of patients with symptoms of carpal tunnel syndrome is important for good care. Patients with mild manifestations of median entrapment can present a great challenge in early detection for treatment and prevention of progression. The electrodiagnostic assessment should assess the degree of conduction slowing, the presence of neurapraxia, or axon loss, and isolate the site of injury. Frequent coexisting conditions such as polyneuropathy with predisposition to superimposed entrapment must be considered. The methods presented in this article are sensitive and accurate for median mononeuropathy at the wrist, but interpretation in light of clinical research is essential for patients to be well served.
