J. Ito et al., ASSESSMENT OF VISUOPERCEPTUAL DISTURBANCE IN CHILDREN WITH SPASTIC DIPLEGIA USING MEASUREMENTS OF THE LATERAL VENTRICLES ON CEREBRAL MRI, Developmental Medicine and Child Neurology, 38(6), 1996, pp. 496-502
The authors estimated perceptual disturbance in children with spastic
diplegia from the difference between the visual and performance IQ sco
res (VIQ-PIQ) on the Wechsler Intelligence Scale for Children-Revised
(WISC-R), having found a strong negative correlation between this scor
e and the PQ obtained on the Frostig Developmental Test of Visual Perc
eption (DTVP). The ratio of the areas of the posterior horns to the an
terior horns (PIA) correlated negatively with visuoperceptual disturba
nce. This ratio call therefore be used to assess perceptual disturbanc
e at an early age in children with spastic diplegia.
