This chapter covers the electrodiagnostic (EDX) evaluation of upper extremity nerves and the brachial plexus. Carpal tunnel syndrome is the most common peripheral nerve disorder of the upper extremity. A number of techniques are used but there is no gold standard approach for its diagnosis. Needle EMG aids in the differentiation of proximal and distal median neuropathies. Ulnar neuropathy at the elbow and ulnar neuropathy at or distal to the wrist can be distinguished by EDX techniques. Radial neuropathy at the spiral groove has a specific EDX pattern. EDX assessment of proximal upper extremity nerve lesions such as brachial plexopathy is a valuable tool for exploring the diagnosis and differential diagnosis of this complex disorder.
本章涵盖上肢神经和臂丛神经的电诊断（EDX）评估。腕管综合征是上肢最常见的周围神经疾病。虽然使用了多种技术，但对于其诊断尚无金标准方法。针电极肌电图有助于区分近端和远端正中神经病变。通过EDX技术可以区分肘部尺神经病变和腕部或腕部以下的尺神经病变。螺旋沟处的桡神经病变有特定的EDX表现。对近端上肢神经病变如臂丛神经病变进行EDX评估是探索这种复杂疾病诊断和鉴别诊断的重要工具。
