Fig 2. Balance parameters during quiet standing with eyes open and eyes closed.

Fig 2

(A, B, C) Ankle anterio-posterior (AP), medio-lateral (ML) deviations (deg), and sway (deg^2), respectively. (D, E, F) Hip anterio-posterior (AP), medio-lateral (ML) deviations (deg), and sway (deg^2), respectively. (G, H, I) COM anterio-posterior (AP), medio-lateral (ML) displacements (cm), and sway (cm^2), respectively. Grey bars depict parameters measured during standing with eyes open. Black bars depict parameters measured during standing with eyes closed. A star (*) indicates parameters in a group, which were significantly different during standing with eyes open and eyes closed (repeated measures MANOVA). Two stars (**) indicate parameters of different groups, which were significantly different during standing with eyes closed (Tukey HSD test). Three stars (***) indicate parameters of different groups, which were significantly different during standing with eyes open (Tuckey HSD test). HY–healthy young persons. HE–healthy elderly persons. FR–elderly persons at high risk of falling persons.
