The posture of school children was studied to find the method to correct their poor postures. The development of the back muscles which are related to the posture maintenance and the equilibrium was also examined.
Moiré-topography method was used for measurement. Subjects were 537 boys and girls at 2nd to 6th grade of elementary school and the their full-length bach figures were photogrphed.
The following results were obtained.
1. Those who had an abnormal posture were 239 pupils, 44.5% of the whole. Those who had a normal one were 298, 55.5%.
2. As for the reform training, the following exercise proved to be effective. The child whose right side waist is higher than the left should turn the face rightward, wherever practicable, carry the bag in the right hand, and stand on an inclined plane as the right side on the inclined side. The child whose left waist is higher than the right should do the reverse movements.
3. Most of the child who had good posture could stand on one leg with eyes closed for longer time, and balanced themselves on the forward side of their legs when they stood correct. Their good poise had no relation to the development of the back muscles.
