| Research Abstract |
We attempted to measure of spinal cord evoked magnetic fields by peripheral nerve stimulation on upper limbs over the body surface in healthy volunteers and patients with myelopathy for the purpose of the establishment of a noninvasive procedure of evaluating spinal cord function. Large conducting magnetic fields equal to the method using the epidural electrode stimulation were obtained by renovating condition of stimulation and measurement from conventional methods. It was proved by the accordance of the latency with spinal cord evoked potentials that the obtained magnetic fields originated from neural activity of the spinal cord. Furthermore, we performed diagnosis of involved site in patients with cervical myelopathy by using peripheral nerve stimulation for the first time in the world.
