Carpal Tunnel Syndrome: Diagnosis [Clinical Review Discussion]

The diagnosis of carpal tunnel syndrome (CTS) is not nearly as straight forward as one might think.  Although long considered the “gold standard” for evaluating CTS, electrodiagnostic studies (EDS) seem to have as many critics as adherents.  Based on the available studies, a high quality history and examination appears to be the most cost efficient and accurate path to a proper diagnosis, particularly when conservative treatment remains the first treatment option.  Electrodiagnostic studies are of value in a properly selected subgroup of patients where surgical intervention is being considered or diagnosis is uncertain.
