Background and aims: Posturography is a non invasivetechnique to objectively assess postural control. Weinvestigated the relationship between stabilization indexesafter mirror exposure and body image psychologicalappraisal measures in a diagnosed eating disorderpopulation, comparing it with a healthy subject one.Methods: Clinical population (N=17) and control healthypopulation (N=17) were matched for age and sex. BMI wasrecorded and every subject was administered the Italianversions of psychometric instruments assessing body imageself-perception. Static posturography (S.Ve.P. Amplifon)was performed measuring body sway with eyes open (EO)or closed (EC) during exposure to a full size mirror (M) ofa fashion model (FM) a neutral object (NO) or a verticalbar (VB). We reported descriptive statistics for sociodemographicdata and t test to compare psychometric andposturographic scores.Results: Cases and controls significantly differed inpsychometric scoring scales measuring body imageconcerns and phobic reaction (p<.001). Posturographicmeasures were significantly only in the EO and VBcondition (p<.05) and in the M and FM ones (p<.01).Conclusions: Results confirm the hypothesis thatposturography measures of female eating disorderedpatients differ from those of a control group.
