The postural sways of the centre of pressure, the trunk and the head were simultaneously measured during undisturbed stance in orthostatic position in 10 normal young subjects. The statistical distribution of each sway signal was constructed, and open- vs. closed-eye postures were compared. Preliminary results provide evidence for shifts of mean centre of pressure position when vision was prevented, whereas the statistics of the other sways was almost unaffected by vision conditions. No correlation could be proven between the different sways. Implications of these results are discussed.

Abstract
The postural sways of the centre of pressure, the trunk and the head were simultaneously measured during undisturbed stance in orthostatic position in 10 normal young subjects. The statistical distribution of each sway signal was constructed, and open- vs. closed-eye postures were compared. Preliminary results provide evidence for shifts of mean centre of pressure position when vision was prevented, whereas the statistics of the other sways was almost unaffected by vision conditions. No correlation could be proven between the different sways. Implications of these results are discussed.File in questo prodotto:
