[Somatosensory evoked potentials (SSEP) in patients with multiple sclerosis (MS)--correlations with clinical studies]

Somatosensory evoked potentials were studied in 50 patients with clinically reliably confirmed diagnosis of multiple sclerosis in various disease stages. In a part of these patients the study was repeated after 3 years. The latency changes, amplitude changes and shape abnormalities of the obtained N9, N13 and N20 responses were evaluated. The authors discuss the observed changes of these potentials in relation to clinical findings and analyse the evolution of potential changes during the disease.
