Abstract: Objective To evaluate the diagnostic value of sympathetic skin response(SSR)in patients with vestibular vertigo.Methods SSR tests were performed on 1 20 patients with acute vestibular system vertigo,including 70 cases of central vertigo and 50 eases of peripherM vertigo.60 healthy subjects were also examined to serve as controls.Results In those with central vertigo,the abnormality rate in the SSR results was 87.1%(61/70).SSR latency was longer and its amplitude wag lower than in those with peripheral vertigo and in the heMthy controls.In those with peripheral vertigo the abnormality rate was 18.0%(9/50),but the average latency and amplitude were not significantly different from those of the healthy controls.Conclusion Persons with acute central vestibular vertigo may have sympathetic nerve dysfunction.SSR test results can be used as an electrophysiological index to distinguish central from peripheral vestibular vertigo.
