[Motor development in children with muscular dystrophy of the Duchenne type].
For determination of the age of onset and the age of immobilization in Duchenne's progressive muscular dystrophy the motor development was studied in 129 affected children. It was demonstrated that motor development was delayed and abnormal in 58% of the cases. On the average the affected children started to walk in the 19th month of life. According to the history data in 83% of the cases the age of onset of the disease was 1 year; in 10% of the cases the onset was placed before and in 7% after the 5th year of life. It was observed that earlier age of onset was not associated with a more rapid development of the disease and independently of the onset the age of immobilization was about 10 years. The results of investigation were compared with reports in the literature.
