Abstract:
Carpal tunnel syndrome (CTS) and ulnar mononeuropathies at the elbow and wrist are the most common nerve entrapments in the upper extremities. Electrodiagnostic studies are a valid and reliable means of confirming the clinical diagnosis. This review addresses various electrodiagnostic techniques to evaluate the median and ulnar nerves at the wrist and elbow. It also discusses the limitations of electrodiagnostic studies with regard to the sensitivity and specificity of such testing.
