[Syringomyelia. Clinical and neurophysiologic correlations (SEP) as a function of surgical treatment].

The authors have studied the somatosensory evoked potential (SEP) behavior following stimulation of upper and lower limbs in two subjects affected by syringomyelia. The patients were evaluated electrophysiologically before and after decompressive surgical treatment. The findings indicate a positive correlation between the SEP recordings and the role of CSF pressure in the central nervous system.
