A developmental study of handedness in Down syndrome pupils.
Assessed hand preference in 7- to 9-yr.-old and 13- to 15-yr.-old pupils with Down syndrome (n = 41) was compared with control schoolchildren (n = 50) of the same ages. A significant increase in left-handedness and mixed-handedness was noted in Down syndrome groups compared with the normal population. Younger Down syndrome pupils were less consistent in their hand preference than the older pupils and the normal controls.
