A posture equilibrometer for the diagnosis of vestibular disease

Since the vestibulospinal level of vestibular function is frequently neglected in the evaluation of vertiginous patients, we developed a new posture equilibrometer for recording body swaying X (left-right) and Y (fore-aft) components of angular displacement, velocity, and acceleration with its transducer on the head of the subject. The data from patients undergoing Romberg test with eyes open and closed, Romberg test with head turned left and right and Mann test were analysed. We conclude that the equilibrometry allows one to evaluate precisely the vestibulospinal function and the sensory interaction.
