自1972年以来，MDT已在234例慢性疼痛患者，140例痉挛状态患者和12例神经源性膀胱过度活动症患者中进行。在最后64例患者中，术中记录了脊髓表面的诱发脊髓电图，以监测手术损伤所产生的电生理效应，不仅对进入背柱的丘系纤维的传导，而且对背角细胞的突触后反应。N13或N22波幅的降低与DREZ损伤的深度和宽度以及手术节段的数目密切相关，在大多数情况下，波幅降低2/3的数量级被认为是最佳值。
Since 1972, MDT has been performed in 234 patients with chronic pain, 140 with hyperspasticity and 12 with hyperactive neurogenic bladder. In the last 64 patients, the evoked electrospinogram has been recorded intraoperatively from the surface of the spinal cord, to monitor the electrophysiological effects produced by the surgical lesioning, not only on the conduction of lemniscal fibers when entering the dorsal column, but also on the postsynaptic responses of the dorsal horn cells. The decrease in amplitude of the latter responses (N13 or N22) was well correlated with (1) the depth and the width of the DREZ lesion, and (2) the number of spinal segments operated on. In most cases, amplitude was reduced in the order of 2/3, which was considered the best value.
