摘　　要：目的探讨对冲阻滞神经电生理技术在早期肘管综合征中的应用价值。方法对30例有典型临床症状疑诊为肘管综合征的患者，分别采用常规神经电生理方法和对冲阻滞电生理技术检测肘段运动传导速度（为正常值下限），并对运动传导速度进行比较。结果应用常规检测法检测30例肘段尺神经运动传导速度（MNCV）平均为（45．20±4．20）m／s，均在正常值下限；而对冲阻滞神经电生理技术检测的尺神经运动传导速度平均为（35．12±3．01）m／s，均明显低于正常值，且波幅均降低。结论对冲阻滞神经电生理技术能对冲肘上正中神经的兴奋，只记录到尺神经复合肌肉动作电位（CMAP），能更准确更早地反映肘段尺神经的NNCV，提高诊断率。Objective To investigate the diagnostic value of collision electrophysiologic technique in patients with early eubital tunnel syndrome. Melhods Thirty patients with typical clinical symptoms and suspected eubital tunnel syndrome were involved in the study. Motor nerve conduction velocity （MNCV） （lower limits of normal value） in the ulnar nerve at the elbow was by measured routine electrophysiologic method and collision technique respectively and the results were compared. Results In 30 patients, MNCV in the ulnar nerve at the elbow measured by the routine method was （45.20 ± 4.20） m/s （all within the lower limits of normal value）. However, MNCV in the same nerve measured by collision technique was （35.12 ± 3.01 ） m/s （all below the normal value）. Attenuation of the amplitude was also found in all patients with the collision technique. Conclusion The collision technique maybe a useful and accurate method in diagnosis of early cubital tunnel syndrome.
