Outline of Final Research Achievements |
In 52 healthy subjects between the ages of 20 and 70, the magnetospinography at the lumbar spine in response to the peroneal nerve stimulation were measured to establish a control group for healthy volunteers. It became clear that the nerve conduction velocity of the cauda equina decreases with age. We also measured the magnetospinography of the lumbar spine in 43 patients with lumbar nerve lesions and we have improved the measurement method and the diagnosis algorithm of the affected site. A newly developed display method of action current at the depolarization site using virtual electrodes made it possible to diagnose the neuropathy lesion in patients with the lumbar radiculopathy.
