Spontaneous Leg Movements of Infants with Down Syndrome and Nondisabled Infants.

Compared the spontaneous leg movements of 10 infants with Down Syndrome to those of nondisabled infants matched for chronological age and motor age. Contrary to expectations, no significant difference was found in the frequency of leg movements between the two groups. However, Down Syndrome subjects demonstrated significantly fewer of the most complex patterned leg movements, that is, kicking patterns. (Author/HTH)
