Abstract
|
|
|
This study investigated the effect of anticipatory postural adjustment on balance
performance in postural disturbance. Any action performed by standing subject is
generally accompanied by compensatory postural activities, which reduce or abolish the
postural disturbance generated by the movement and keep the subjects' center of
gravity within the supporting base. These postural activities are triggered by either
anticipatory and feedback postural control. We studied the difference of anticipatory and
feedback postural control in postural disturbance. The subjects were standing on a foot
plate with eyes closed, holding a load of 5% of their own body weight in their hands.
The condition of anticipatory postural adjustment was applied voluntarily releases the a
load. The condition of feedback postural control was applied that the load was
unpredictably removed. We concluded that anticipatory postural adjustment becomes
more efficient to postural performance in postural disturbance.
