Abstract
To assess the effects of a program of physical activities consistent with the Doman-Delacato theory of neurological organization on the physical and intellectual development of trainable mentally retarded children, pretest and posttest data were collected from a Doman-Delacato experimental group and a nonspecific activity control group. In motor development, no significant pretest, posttest intergroup differences were found. Comparisons on mobility (creeping and crawling) and IQ (PPVT) yielded statistically significant gains in favor of the experimental group. The findings suggest the Doman-Delacato techniques may be beneficial with trainables in public schools.
