在脊髓型颈椎病患者的椎板间黄韧带后方或椎间盘前方记录正中神经和脊髓刺激引起的脊髓诱发电位（ESCP），以确定脊髓电生理学上最显著的病变。正常正中神经诱发脊髓电位（MN-ESCP）由P1 N1和N2（P2）偏转组成，而正常脊髓上行诱发脊髓电位（SC-AESCP）由N1和N2偏转组成。65例患者ESCPs异常分为3级。记录ESCP最高级别的脊柱节段（大多为阳性波）通常对应于神经系统和放射学检查明确诊断为主要病变的节段，例如单节段椎间盘疝病例。后段和前段对原发灶的定位诊断率分别为94.7%和74.1%。
The ESCPs (evoked spinal cord potentials) resulting from both median nerve and spinal cord stimulation were recorded from the interlaminar yellow ligaments posteriorly or intervertebral discs anteriorly on patients with cervical myelopathy in order to determine the most significant lesion in the spinal cord electrophysiologically. The normal median-nerve-evoked spinal cord potential (MN-ESCP) consisted of P1N1 and N2(P2) deflections, while normal spinal cord-ascending evoked spinal cord potential (SC-AESCP) consisted of N1 and N2 deflections. The abnormal ESCPs obtained from 65 patients were classified into three grades. The spinal level recording the highest grade of ESCP, which was mostly positive wave, generally corresponded to the level that was clearly diagnosed as the main lesion by neurologic and radiologic examinations, such as a case of single level disc hernia. With these techniques, the level diagnostic rates of primary lesions were 94.7% in posterior recordings and 74.1% in anterior recordings.
