Abstract
We analyzed the course of motor disability in patients with Duchenne type muscular dystrophy by means of Motor Age Test. The duration of the motor age was divided into nine parts from lower motor age to higher motor age. The performance rate of each parts, which consisted of several motor tasks, was calculated in each patient. Comparative study was carried out between motor disability stage and performance rate. As motor disability stage progressed, the performance rate decreased significantly from higher motor age to lower motor age.
From these results, it was suggested that the course of motor disturbance in patients with Duchenne type muscular dystrophy is the same as, but in the opposite direction to the course of motor development in normal children.
