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 arc 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 lead 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.
