脊髓损伤造成截瘫的患者,至今仍然缺少比较客观的诊断技术,以至在确定治疗方案以及估计预后方面尚存在一定困难。许多作者在动物及人体上观察了脊髓的电活动以及脊髓损伤后电活动的改变。早在1933年,Gasser就在猫身上,刺激背根,从脊髓背面记录了诱发电位;Pool最先从截瘫患者断离脊髓的尾段记录了人体自发活动及刺激诱发反应,并把它命名为脊髓电图(ESG);自此以后,直接描记脊髓的自发与诱发电活动在人及动物身上进行了许多研究。但直接描记法要损伤机体,有其局限性。近代进展在体感诱发电位记录方面产生了无损伤记录方法,用来测定神经系统从外
Patients with paraplegia caused by spinal cord injury still lacks more objective diagnostic techniques so far that there are still some difficulties in determining the treatment plan and estimating the prognosis. Many authors have observed in animals and humans the electrical activity of the spinal cord and changes in electrical activity following spinal cord injury. As early as 1933, Gasser was on a cat and stimulated the dorsal root to record the evoked potentials from the back of the spinal cord. Pool first cut off the tail section of the spinal cord from the paraplegic, recording the spontaneous activity of the body and stimulating the evoked response and named it Spinal Electroencephalography (ESG); Since then, there have been many studies that directly characterize the spontaneous and induced electrical activity of the spinal cord in humans and animals. But the direct description method to damage the body, has its limitations. Recent advances in the recording of somatosensory evoked potentials resulted in a nondestructive recording method used to measure the nervous system from the outside
