The clinical application or posturography in the diagnosis of the patients with vertigo

Abstract: Objective To evaluate the clinical application of posturography in the diagnosis of the patients with vertigo and the differentiation in central and peripheral vertigoes. Methods The parameter was measured with posturography during 1 minute period in 71 normal subjects and 185 patients suffering from central and peripheral vertigoes. Results The length of locus was the shortest and velocity of sway was the slowest in the 30-year group. The difference between 30-year and 50-year was more significant (F0. 01);Centripetal pattern was the most prominent figure pattern in the normal subjects,and diffuse pattern was the most prominent figure pattern in the central vertigoes ; Length of locus and velocity of postural sway of the patients were significantly increased in comparision with normal subjects. There were no difference in central and peripheral vertigoes. Conclusion The decline of vestibular function start from 30-year. The posturography can discern the central vertigoes from the peripheral roughly.
