Abstract: The present paper measured and analyzed through LorAn plantar pressure equipment the static balance ability, plantar pressure characteristics and gait characteristics of children aged 8 to 9 with abnormal foot arch to obtain their plantar pressure distribution characteristics,and provide theoretical data support for the scientific rehabilitation therapy and intervention for children. The research indicates that (1) children with high foot arch have a weakerbalance ability as compared with children with normal foot arch; (2) as compared with normal foot arch, flat foot arch has much larger contact area and pressure, and high foot arch has much smaller contact area and pressure; (3) as compared with children with normal foot arch, the fourth metatarsal of children with flat feet has smaller contact area, and the lateral pressure of their heel is significantly smaller when they are standing, and their first phalanx has smaller contact area when they are walking; the third-fifth metatarsals of children with high foot arch have larger contact area when they are standing.
