Developmental perspective of sensory organization on postural control

The development of sensory organization on postural control was studied using computerized dynamic posturography. Generalized postural stability increased with age but had not reached the adult level at the age of 15 years. The significance of each sensory component for postural control was analysed. Somatosensory function developed early and became comparable with the adult level at the age of 3-4 years. The visual function followed and reached the adult level at the age of 15 years. The vestibular function developed later, showing a considerably lower level even at the age of 15 years. Girls were superior to boys with respect to the vestibular function at the age of 7-8 years. The implication of this sexual difference for some developmental disorders is discussed.
