短潜伏期体感诱发电位(SEP)广泛用于研究神经系统疾病。在外伤性脊髓病变中,通过刺激下肢神经引出的头皮电位记录已被用于脊髓损伤的功能估价。Rowed等对手术后至6周的病人进行了系列研究,证实外伤痊愈与诱发电位恢复之间正相关。peret和Vera研究55例不完全性颈髓损伤病人,发现正中神经和胫后神经诱发电位早期恢复正常提示预后良好,并指出随着病情好转,诱发电位的波幅和潜伏期逐步改善。基于上述报告可以预期在外伤后数月,体感诱发电位正常的病人,其下肢功能恢复最好,而诱发电位异常者则恢复最差。本文报导25例不完全性颈髓损伤,其检查是在明显发生临床最大好转时进行的。方法:观察27例正常人和35例不完全性颈髓损
Short latency somatosensory evoked potential (SEP) is widely used to study nervous system diseases. In traumatic spinal cord lesions, recording of scalp potentials induced by stimulation of the lower extremity nerves has been used for functional assessment of spinal cord injury. Rowed et al conducted a series of studies of patients after 6 weeks of surgery, confirming a positive correlation between trauma recovery and recovery of evoked potentials. Peret and Vera study of 55 cases of incomplete cervical cord injury patients and found that the median nerve and posterior tibial nerve evoked potentials early recovery prompted a good prognosis and pointed out that with the condition improved evoked potential amplitude and latency gradually improved. Based on the above report, it is expected that in patients with normal somatosensory evoked potentials for months after trauma, the functional recovery of their lower limbs is best, while those with abnormal evoked potentials recover the worst. This article reports 25 cases of incomplete cervical spinal cord injury, the examination was carried out in the obvious clinical maximum improvement occurred. Methods: 27 cases of normal and 35 cases of incomplete cervical cord injury were observed
