Evoked potentials in patients with lumbar spine stenosis

As the results of complex examination of patients with compressive syndromes accompanied by spinal stenosis we determined main factors and types of compression of spinal cord roots. We analyzed electroneuromyography of 64 patients who had in their anamnesis osteochondrosis of the 2-3rd gestation per...
