Nerve conduction studies are widely employed in evaluating patients with peripheral nerve disease and are often used serially to measure disease progression or to assess a therapeutic intervention. We determined the inter- and intra-examiner reliability of electrophysiological data by performing serial nerve conduction studies on 7 normal subjects. A high degree of intra-examiner reliability was present, but significant inter-examiner differences were found. Our results suggest that if nerve conduction studies are to be used longitudinally, they should optimally be performed by a single examiner to minimize the degree of variability associated with different examiners.
神经传导研究广泛应用于评估周围神经疾病患者，并且经常连续使用以测量疾病进展或评估治疗干预措施。我们通过对7名正常受试者进行连续神经传导研究，确定了检查者之间和检查者内部电生理数据的可靠性。检查者内部具有高度可靠性，但发现检查者之间存在显著差异。我们的结果表明，如果要纵向使用神经传导研究，最好由一名检查者进行，以尽量减少与不同检查者相关的变异性程度。
