Purpose : The objectives of this study were to examine changes in gait parameters related to the COP and gait velocity resulting from the use of ankle foot orthosis, and to provide information for the prescription of ankle foot orthosis and gait rehabilitation training. Methods : We sampled a control group of 14 normal children of the same age as the spastic diplegia (spastic diplegia used ankle foot orthosis) and measured their COP at barefoot gait and their gait parameters at three gait velocities. Change in the COP according to the use of ankle foot orthosis measured one-way ANOVA and Gait parameters according to gait velocity used repeated measures ANOVA. Results : As a result of analyzing change in the COP it became close to that of normal children, and changes in gait parameters such as step width, stride length and stride time also became close to those of normal children. Conclusion : In conclusion, when spastic diplegia used ankle foot orthosis, their balancing ability was improved as a result of decreased change in the COP, and their changes in gait parameters also became close to those of the control group. These results show that the use of ankle foot orthosis improves spastic diplegia gait functions.
