Abstract
In this study, the physical characteristics of the 323 young people with visual and aural impediment in Kumamoto Prefecture were examined. 1. The growth of the height and sitting height in male with visual and aural impediment were similar to those normal children at a young age. In females, there were noticeable difference in second sexual character between impedimental and normal children. 2. Retarded growth of the chest circumference in males was seen in aural impediment children after 13 years of age. As for females, a converse phenomenon was found. 3. No differences were observed in the weight game of males among visual impedimental children, aural impedimental children and normal children. However, visual impedimental children and aural impedimental children (females) exhibited retardation of growth in the 12-13 years old group. 4. As for the skeletal development in females, we found retarded development in visual impedimental children and aural impedimental children and normal children in the period of the second sexual character with respect to the bicristal diameter. But, as for biacromial diameter, chest-width and chest-depthin both sexes of the impedimental group had the same development tendency as normal children. 5. The changes of Rohrer's Index were similar among the visual impedimental children, aural impedimental children and normal children (males) . However, in females, the visual impedimental children and aural impedimental children had a higher rate of change than normal female children over the second sexual character.
