Correlation between temperature and vibration thresholds and somatosensory evoked potentials.
The psychophysically assessed thermal specific, thermal pain and vibration sensitivities were correlated to somatosensory evoked potentials in eighteen patients with definite multiple sclerosis. In the psychophysical tests, modality specific stimuli were used. Somatosensory potentials were electrically evoked. The abnormalities of both the temperature and the vibration sensitivity were to same extent related to the somatosensory evoked potentials. Dorsal columns-medial lemnisc and anterolateral-spinothalamic demyelinating lesions were presumed. The psychophysical tests supplement the clinical, laboratory, neuroradiologic and electrophysiological tests. These should be included in the battery of diagnostic tests in multiple sclerosis.
