The psychomotor development of 130, one- to nine-year-old children was followed. Their development was not, as a rule, found to occur abnormally.
The further development of twins was found to be in close correlation:
(1) with the condition after birth (43% of complications in the further development of children having at birth a 1-7 Apgar score);
(2) with the weight at birth (35.2% of complications in a weight group of 1001-1500 g): this is connected with dystrophy and prematurity;
(3) with the order in which the twins were born.
