我们曾用从头皮记录的累加脑诱发电位为指标,探索对脊髓损伤引起的截瘫病人的新的诊断手段,以便在决定是否需要手术探查以及预测能否恢复和恢复难易等方面提供了一种比较客观的估计方法。该项研究已在人体上得到了肯定的结果。由于脊髓损伤造成截瘫的病人,至今仍然缺少比较客观的诊断技术,作为一项新的临床诊断技术,除了人体结果以外,必须在脊髓横断的动物上得到进一步的确证。为此进行了本研究。自Gasser等刺激背根从放置在猫脊髓背面的电极记录了诱发电位以来,曾有许多学者 We have used the cumulative head evoked potentials recorded from the scalp as an indicator to explore new diagnostic tools for patients with paraplegia caused by spinal cord injury so as to provide a means of determining whether surgical exploration is needed and of predicting recovery and recovery difficulties More objective method of estimation. The study has yielded positive results in humans. As a result of spinal cord injury paraplegia patients, there is still a lack of more objective diagnostic techniques, as a new clinical diagnostic techniques, in addition to human results, must be further confirmed in spinal transected animals. This study was conducted for this purpose. Since Gasser et al have stimulated dorsal root to record evoked potentials from electrodes placed on the back of the cat’s spinal cord, there have been many scholars
