We recorded the sympathetic skin response (SSR) from electrical nerve stimulation in 16 patients with cerebrovascular accident (CVA). Location and nature of the lesion were documented by computerized tomography (CT). Median (pre-rolandic and parietal) somatosensory evoked potentials (SEP) were also recorded. SSR was absent bilaterally in eight hemiplegics after stimulation of the plegic side and present bilaterally after stimulation of the normal side in the first weeks after CVA.

Absence of the electrically evoked SSR in hemispheric lesions may be due to involvement of central afferent pathways or temporary suppression of suprasegmental excitatory influences. © 1992 Éditions Scientifiques Elsevier, Paris.

Abstract
We recorded the sympathetic skin response (SSR) from electrical nerve stimulation in 16 patients with cerebrovascular accident (CVA). Location and nature of the lesion were documented by computerized tomography (CT). Median (pre-rolandic and parietal) somatosensory evoked potentials (SEP) were also recorded. SSR was absent bilaterally in eight hemiplegics after stimulation of the plegic side and present bilaterally after stimulation of the normal side in the first weeks after CVA. Parietal and pre-rolandic SEPs were absent in the affected hemispheres. SSR was present bilaterally after stimulation of each side in the remaining CVA cases with reduced amplitude SEPs. Absence of the electrically evoked SSR in hemispheric lesions may be due to involvement of central afferent pathways or temporary suppression of suprasegmental excitatory influences. © 1992 Éditions Scientifiques Elsevier, Paris.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
