Abstract
Aim. Neuro-muscular adaptations to the loss or increase in body weight may induce postural alterations. The aim of this study was to investigate the effect of body weight alterations on postural stability in patients with anorexia nervosa and bulimia. Methods. The study enrolled 15 women affected by anorexia nervosa (AN), (mean body mass index [BMI] 15.8±1.8 kg/m2), 15 women affected by bulimia nervosa (BN), (mean BMI 20.1±2.9 kg/m 2) and 11 healthy matched women (HC), (mean BMI 20.1±1 kg/m2). Two quiet standing conditions with eyes open (EO) and closed (EC) were analysed with an optoelectronic system (Vicon 460, Viconpeak, Oxford, UK) with passive markers to estimate the centre of mass (CoM) position. Results. BN patients were more unstable than HC, showing statistically significant differences in antero-poste-rior CoM excursions and path length. AN patients showed non significant differences from HC. Only HC showed differences between EO and EC conditions, with significantly greater excursions in medio-lateral direction in EC condition (P
