Abstract:
The purpose of this study was to examine and analyze the distribution of pressure under the feet School Children who were carrying different loads on their backs and were walking through the Footscan plantar pressure distribution analytical system. The result showed that the maximum force on the second and third metatarsus increased and the contact phase of walking delayed while walking with a bag weighing 4 kilograms. The variation of center of sure (COP) in mediolateral (M/L) direction was larger. The children must move limb to maintain balance. The proportion of foot pronation and supination enhanced the cause of an ankle sprain. The findings of this study suggest that, for prevention of abnormal corpus callosum and for the normal development of the arch, attention should be given to restricting the weight of children's schoolbags and to avoiding their overloaded walking or standing for a long time.
