Plantar Pressure Characteristics of Toe-in Gait Children and Corrective Effects with Different Management

The aims of this study were to explore the plantar pressure characteristics of toe-in children with Rscan plantar pressure system, and to compare and evaluate the effects of different treatment.20normal gait children and 40bilateral toe-in children with the age of 3-5years were recruited.All toe-in children were required to sit without“W ”and“cross-leg”position and to sleep without prone position.The difference between two randomly divided groups was that one group wore Dannis-Brown corrective shoes and the other did not.The results showed 1) Toe-in gait of children can be classified as three levels:mild (0°^-10°) , moderate (-10°^-18°) and sever (more than-18°) , 2) There were significant differences between normal and toe-in gait children in progressive angle, heel valgus angle, regional Maximum plantar pressure and impulse, 3) The progressive angle of Dannis-Brown group changed faster compared with No-Dannis-Brown group during the whole corrective period, 4) Comparing with normal gait children, the seemingly normal gait children after 6 months still had statistical differences on progressive angle, heel valgus angle, regional Max pressure and impulse.Based on this research, the conclusion had been made that neither corrective shoe nor changing harmful position was ideally corrective method.It suggested that further comprehensive biomechanical study should be made to find corrective methods from muscle strength training.
