Somatosensory evoked potentials after magnetic stimulation at different points of the body in normal subjects and in patients with syringomyelia.


Somatosensory evoked potentials (SEPs) were elicited by magnetic stimulation of the tibial nerve, gastrocnemic muscle and by stimulation over the spinous processes of lumbar vertebra 5 (L 5), thoracic vertebra 9 (Th 9) and cervical vertebra 7 (C 7). The first SEP-positivity (P1-latency) was measured in a group of 20 controls and in another group of 18… (More)
