Use of posturography to identify the risk of falling in elderly people with dizziness

Abstract

Purpose the aim of this study is to determine whether posturography, an exam used to investigate the ability to maintain balance under conflicting sensory conditions, can identify the risk of falls in eldery patients with dizziness. Methods to compare the posturographic results of elderly people with falls vs elderly people with no falls, paired by sex, age and dizziness etiology. Results 18 fallers, and, of these, 14 with two or more falls in the last year were compared with 18 elderly people without falls. Comparing subjects without falls vs subjects with at least one fall in the last year, fallers obtain worse scores in conditions of visual dependence. Comparing non fallers with subjects with two or more falls, people with recurrent falls obtain worse score in several conditions: somatosensorial, vestibular, visual conflict, and in the main measure, the composite score. Conclusion posturography appears to be a useful tool to identify those at high risk of recurrent falls.
