The change of motor functions in normal aged was investigated quantitatively by the motor age age evaluating method deduced from developiog motor functions in normal children. Analysis was carried out in two directions. One was the process of decreased motor functions and another was the grade of progressive disability in motor functions as the age increased. The subjects were 77 cases in normal aged, ranging from 60 y.o. to 83 y.o.. The mean±SD was 69.3±5.4. The following results were obtained.
1) The motor age score decreased as the age increased. The variance was also increased. The significant change (p<0.02) in the motor age scores was found between their eightieth and the ages ranging from 74 to 79 y.o..
2) As the age increased the sex differences in the change of motor age scores were also decreased as follows. In females, significant change was clasified between the ages ranging from 65 to 69 y.o. and 70 to 74 y.o. In males significant change was classified between the ages ranging from 70 to 74 y.o. and the 75 to 79 y.o..
3) The pattern of progressive disability in normal aged was not the reversal pattern of normal motor development from the analysis of the motor items of the motor age.
