BRUNIERA, Juliana Ribeiro Zuculin et al. Comparative analysis of postural balance by posturography in patients with isolated vertigo or associated with hearing loss. Audiol., Commun. Res. [online]. 2015, vol.20, n.4, pp.321-326. ISSN 2317-6431.  http://dx.doi.org/10.1590/2317-6431-2014-1534.

Purpose:

To perform a comparative analysis of the balance of subjects with isolated vertigo and dizziness associated with hearing loss.

Methods:

The sample consisted of 29 patients with peripheral vertigo diagnosis selected by non-probabilistic sampling and convenience aged between 45 and 64 years. The diagnostic survey to hearing evaluation consisted of audiological anamnesis and assessment of postural balance; it was made in force platform, in the bipedal and semi tandem positions with open eyes. The analyzed balance parameters were: ellipse area, center of pressure in square centimeters, average speed in centimeters per second and average frequency, in Hertz, of swaying in both directions of movement: anteroposterior and mediolateral.

Results:

As for the population in general, the comparison between individuals with and without hearing loss has not shown to be there any damage to the maintenance of postural balance. There was difference in women in the speed parameter in mediolateral direction.

Conclusion:

Although no differences have been found which might have characterized a correlation between hearing loss and balance in patients, there was a worse performance in postural balance of women with vertigo associated with hearing loss in the mediolateral parameter.
