Segmental electrodiagnosis of compression of individual nerve roots of the cauda equina has been attempted in 45 patients, including cases of disc hernia, spondylsis and spondylolisthesis. The needle electrode was inserted into the nerve root either just lateral to the intervetebral foramen or through the posterior sacral foramen. The recordings made on stimulating a single nerve root were somatosensory evoked potential, the cauda equina action potential and the M and H waves. Mixed spinal nerve root action potentials were also recorded by stimulating the sciatic, peroneal and tibial nerves. It was shown that a diagnosis could be made from the somatosensory evoked potential, the H wave and root pain reproduction, and also the diagnosis of a subclinical compression involvement. In other words, the neurophysiological state of dysfunction of individual roots in each aspect of compression can be expressed.
已对45例患者尝试进行马尾单个神经根受压的节段性电诊断，包括椎间盘突出、脊柱炎和脊椎滑脱病例。将针电极插入椎间孔外侧的神经根或经骶后孔插入。刺激单个神经根时记录的电位有体感诱发电位、马尾动作电位以及M波和H波。通过刺激坐骨神经、腓总神经和胫神经也记录到了混合性脊神经根动作电位。结果表明，可根据体感诱发电位、H波和根性疼痛再现做出诊断，还能诊断亚临床受压情况。换句话说，受压各方面单个神经根功能障碍的神经生理状态均可得以体现。
