An objective evaluation is not yet established about the sensory disturbance in the cervical spondylotic myelopathy.Therefore, in this study, we weighed results of the multimodal measurement such as perception/pain quantitative analysis device (Pain vision) against somatosensory evoked magnetic field (SEF) measurement with the magnetoencephalography in preoperation and postoperation of the cervical spondylotic myelopathy. A record and analysis of the latency and intensity by SEF was useful in an objective effect of treatment judgment, and the evaluation by Pain vision was useful was suggested.
