Background: Clinical tests performed in posturography are a useful element in evaluation of balance and postural control. It usually demands, however, large and expensive equipment and for this reason this examination is not performed by many neurotologists.

Aims/Objectives: This study was conducted with a recently developed posturography system - Balance Angular Posturography (BAP) - in order to evaluate into clinical practice.

Materials and Methods: Fifteen healthy volunteer patients without vestibular disease or complaint of loss of balance were studied prospectively using BAP to establish the reference values of the variables, standardizing its use. They were tested standing over the floor or over a foam platform and were stimulated with right and left Head Tilt, Head-Shaking and right and left Fast Head-Turning tests. The stimuli were presented both with eyes open and closed.

Results: Six male and nine female patients (25,7 average) were enrolled in this study, which the results varied, but allowed for the establishment of reference values.

Conclusion: The validated BAP protocol may become useful to study patients with imbalance complaint and document their improvement after vestibular rehabilitation, since the vestibulo-spinal pathway is also evaluated.

Significance: This equipment may contribute to increase the interest in posturography, particularly with patients that need vestibular rehabilitation.
