Abstract
The perception of verticality is mainly based on utricular afferent signals and central processing of the transmitted signals. However, there are also extracranial receptors that make a considerable contribution to the perception of verticality. With the subjective visual vertical (SVV) for the utricle and the subjective trunk vertical (STV), two different parameters are available that are not fully understood in terms of their response to physiologic and pathologic changes. The aim of this work was to determine SVV and STV under certain positions of the head and trunk as well as under the influence of Menière's disease (MD) as a chronic vestibular disease. In a prospective clinical study, 26 patients with MD and 39 healthy volunteers were recruited. Subjects were examined with C‑SVV glasses and with the three-dimensional trunk excursion chair, while head and torso positions were varied. In both groups, SVV determination is clearly more accurate with an earth-vertical head alignment than with a lateral head tilt (right: MM and control group: p = 0.001; left: MM p = 0.001, control group p = 0.000). If the torso is deflected laterally and the head is held straight, the S...
