Somatosensory evoked potentials were determined in three patients with hysterical neurologic deficits after minor trauma. In each case the patient denied any sensation of the stimulus in the affected extremity; however, normal evoked potentials were recorded. Objective evidence of the hysterical nature of the neurologic deficit was, therefore, provided.
对3例轻度外伤后出现癔症性神经功能缺损的患者进行了体感诱发电位测定。在每例患者中，患者均否认患侧肢体有任何刺激感觉；然而，记录到的诱发电位却是正常的。因此，提供了神经功能缺损为癔症性的客观证据。
