Cerebral palsy (CP) is a developmental disorder of motor, psychological and emotional functions. Its most typical symptom is a walking disorder. The aim of this study was to analyze children's walking abilities based on basic kinematic parameters. In this research, the analysis of a three-dimensional kinematical movement is used to record the right and left parts of the child's body. The walking skills of two CP children are described. For locomotion analysis, the angular displacements in the right and left knees and ankles and foot distortion in both support and swing phases of the walk were chosen. The kinematic parameters can be helpful in the diagnosis and allow physiotherapists to suggest what exercise program should be develop in order to improve the habit of walking.
