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.
对患有颈椎病的患者,分别从后方的椎板间黄韧带或前方的椎间盘记录正中神经和脊髓刺激所产生的脊髓诱发电位(ESCP),以便从电生理角度确定脊髓中最显著的病变。正常的正中神经诱发脊髓电位(MN - ESCP)由P1N1和N2(P2)偏转组成,而正常的脊髓上行诱发脊髓电位(SC - AESCP)由N1和N2偏转组成。从65例患者获得的异常ESCP分为三个等级。记录到最高等级ESCP(大多为正波)的脊髓节段,通常与经神经学和放射学检查明确诊断为主要病变的节段相对应,如单节段椎间盘突出症的病例。通过这些技术,后方记录中原发性病变的节段诊断率为94.7%,前方记录中为74.1%。
