title: [The role of somatosensory evoked potentials in evaluating the treatment of patients with degenerative-dystrophic diseases of the lumbosacral spine].
abstract: Somatosensory evoked potentials (SSEP) were dynamically studied through bilateral stimulation of n. tibialis at the cortical and spinal level in 160 patients with degenerative and dystrophic lumbosacral diseases. The study revealed significant changes in the peaks Pf, N21 and in the intervals Pf-N21 in 38 (23.75%) patients. The patients had generally vascular disorders as ascending arterial, venous or concomitant myeloradicopathies (the syndromes of venous or arterial ischemia of the epiconus or conus). There were SSEP no significant changes in the paralyzing ischiasis syndrome. Early decompressing operations on the vertebral column (within 1 to 3 months) led to reversal of neurological disorders in most patients. Thus, SSEP in combination with needle and stimulant electromyography may quantitatively assess the time course of changes in the spinal cord conductors at and beneath the lumbar enlargement of the spinal cord in the treatment of degenerative and dystrophic lumbosacral diseases.
