INTRODUCTION: Postural control depends on a coordinate function of the visual, somatosensory and vestibular systems. A correct analysis of each of them is necessary, in order to obtain an adequate postural evaluation. METHODS: A normal and a pathological vestibular group of subjects are study. A dynamometric platform studied was performed for every subject in both groups. A scalogram, the centre of pressure variation velocity, and the area, were the parameters analyzed. RESULTS: In both groups, parameters showed higher values when propioceptive and visual system were altered. A pattern of visual dependence was identified in both groups. The scalogram in the normal group showed a minimal centre of pressure variation. In contrast, the pathological group showed a major variation, with differences depending on the compensation status. CONCLUSIONS: Our study protocol with posturography is an adequate instrument of postural evaluation, which discriminates the visual dependence and aids to evaluate the compensation.
