Abstract :
Stabilometry, which is useful for quantitative evaluation of equilibrium function, is generally performed using Romberg´s posture. However, there is a risk of falls in diagnosing diseases such as Meniere disease, sudden deafness accompanied by vertigo, and vestibular neuronitis, measurement of body sway, and course observation of vertigo and balance dysfunction using stabilometry. The aim of this study was to compare the mathematical model in Romberg´s posture with that in a posture in which the heels are together and feet are parallel. Stabilograms of the young were recorded with each posture. The distribution of stabilograms in the 2 postures did not also differ significantly. Therefore, we considered that there was no effect of the postural difference on their stability.
