摘要: We investigated changes in postural sway and its fractions associated with manipulations of the dimensions support area. Nine healthy adults stood as quietly possible, their eyes open, on a force plate well 5 boards reduced The center pressure (COP) trajectory was computed decomposed into rambling (Rm) trembling (Tr) trajectories. Sway components were quantified using RMS (root mean square) value, average velocity, During standing plate, larger for anterior-posterior (AP) than mediolateral (ML) components. area, increased both directions. increase more pronounced when smaller Changes dimension area also affected sway, but not much dimension. ML instability had effects indices compared to AP instability. av...
