Anticipatory aspects of postural control are processed internally when individuals prepare sensory and motor systems for postural demands based on previous experience and learning.16 Anticipatory postural adjustments occur in an “expectant” or feedforward manner prior to action of the prime mover.17 Examples of anticipatory postural con- trol actions include transitions to single limb stance18 and rise-to-toes tasks,19 as well as the initiation of gait20 and functional reach tests.
