Earl y detection of postural disorders is essential for timely interventions in patients with imbalance. Aim: A pilot study describing a new tool for evaluating static postural balance. Study Design: A cross-sectional study of a contemporary series. Material and Method: Twenty-five volunteers (15 women and 10 men) were evaluated. The mean age was 25.8 ± 4.2 years, the mean weight was 63.9 ± 13.1Kg, the mean height was 1.68 ± 0.08 m and the body mass index was 22.3±3.3kg/m2. Posturography was

Tests were carried out with the subjects in the orthostatic position for 90 seconds, with eyes opened(EO) and closed(EC) on stable and unstable surfaces. Results: When the influence of the surface was analyzed (stable x unstable) in the EO condition, there were significant differences in the middle-lateral parameters (m-l) (p=0.004) and total path (p=0.01), and in the m-l (p=0.004) and total (p=0.014) speed. In the EC condition, there were significant differences in all parameters (p<0.001). The influence of the vision was observed in all parameters only on unstable surfaces (p<0.05). Conclusion: The new tool was efficient for analysing postural sway. Braz J Otorhinolaryngol. 2010;76(6):783-8. ORIGINAL ARTICLE
