| 値 | According to our prior research about the functional difference between the right leg and left leg, infants learning to walk use the same leg for both supporting and handling purposes. The supporting function of the leg shifts from the handling leg to the other leg during growth, so adults have a functional advantage with the left leg as the supporting leg. The object of this research is to make clear the effect of separating the supporting leg from the handling leg in the development of the ability to maintain upright balance. Using a STASIO-analyzer, we measured the area of grounded-sole and the vibration of the center of gravity on school children, with the children standing for 20 seconds with closed legs and then for 10 seconds on each leg. The subjects were school children aged 6 to 11, with 97 right-handed boys and 1O7 right-handed girls. The following conclusions were drawn: 1) The area of grounded-sole and its variation show that the right leg's superior function is that of support before the age of eight. After eight, no obvious differences between the right and left legs appear. 2) The vibration area of the center of gravity and the trace length while standing with both legs show that the ability to keep balance improves remarkably until the age of nine, and after that it changes slowly. 3) The vibration area of the center of gravity while standing with one leg shows that a clear distinction cannot be found between right and left stability. 4) We compared the vibration of center of gravity, while standing with both legs, of two groups. One group had small vibration of center of gravity while standing on the left leg, and the other had small vibration while standing on the right leg. The group which had greater stability while standing on the left leg might have a smaller vibration of the center of gravity and be better able to keep balance. Thus, there is a possibility that the separation of the supporting leg and the handling leg affect the development of the ability of school children to keep upright balance. |
