Experimental and clinical studies were performed to measure the segmental spinal evoked potential (SEP) of the cervical cord after stimulation of the median nerve, to determine the location, severity, and outcome of cord lesion in patients who had cervical spondylotic myelopathy. The SEP in control subjects consisted of two waves, the primary reactive R-wave and the secondary reactive N-wave. The R-wave related to both the dorsal root potential and the funiculus posterior potential; the N-wave related to the post-synaptic potential in the spinal cord. In the early stages of cervical spondylotic myelopathy, the N-wave weakens or disappears at the level of lesion. Then, as damage progresses, the R-wave also weakens or disappears.
进行了实验和临床研究，以测量正中神经刺激后颈髓的节段性脊髓诱发电位（SEP），从而确定患有颈椎病性脊髓病患者的脊髓病变位置、严重程度及预后。对照组受试者的SEP由两个波组成，即初级反应性R波和次级反应性N波。R波与背根电位和后索电位均有关；N波与脊髓中的突触后电位有关。在颈椎病性脊髓病的早期阶段，N波在病变水平减弱或消失。随后，随着损伤进展，R波也减弱或消失。
