Intervention 1: • First, using the foot posture index questionnaire (FPI-6), we perform a complete examination of the child's foot and determine its index. Before performing each step, the child walks with each of the shoes( with rigid sole, soft sole and regular shoe) for 5 minutes to adapt to it, and then enters the measurement phase. Using the Kistler force plate device, we ask the child to walk on the force plate once in a position with normal shoes. COP and the parameters of vertical ground reaction forces, anterior posterior and internal external forces of ground reaction during walking are measured and checked. Intervention 2: Intervention group: • First, using the foot posture index questionnaire (FPI-6), we perform a complete examination of the child's foot and determine its index. Before performing each step, the child walks with each of the shoes for 5 minutes to adapt to it, and then enters the measurement step. Using the Kistler force plate device, we ask the child To walk on the force plate with thick sole medical shoes. • COP and parameters of vertical ground reaction forces, anterior posterior and internal external forces of ground reaction during walking are measured and checked. Intervention 3: Intervention group: • First, using the foot posture index questionnaire (FPI-6), we perform a complete examination of the child's foot and determine its index. Before performing each step, the child walks with each of the shoes for 5 minutes to adapt to it, and then enters the measurement phase. Using the Kistler force plate device, we ask the child to walk on the force plane in the condition of thin-soled medical shoes. • COP and the parameters of the vertical ground reaction forces, anterior, posterior and internal external forces of the ground reaction during walking are measured and checked. Yes - There is a plan to make this available What will be shared: The average data will be reported in the paper extracted from the research When: The start of the access period after the publication of the article To whom: public Conditions: The results of this research Where to obtain: contact with : farahmandb1@yahoo.com How to obtain: Depending on the conditions of the journal, the results are printed Comments:

Earth reaction force: According to Newton's third law, the earth reaction force is the force that the earth exerts on an object in contact with it. When a person is just standing, this force corresponds to the person's weight. When the body is moving, the ground reaction force increases due to acceleration forces. The ground reaction force has three components: fz, fx, and fy. • Vertical ground reaction forces Fz • vGRF is the largest component of the ground reaction force along the path. It is walking that results in forces greater than one body weight at each step. The vGRF curve consists of two peaks: the first peak (in the weight bearing phase) and the second peak (push off phase). This force is to support the body and prevent the body from falling during movement. The vertical ground reaction force represents the magnitude and pattern of vertical mechanical loading on the foot and is commonly used in the diagnosis of abnormal gait. The type of movement, the slope of the ground, the speed of movement, body mass, mass distribution, the material of the shoe, the material of the movement surface, and the mechanics of the foot are effective in the amount of this force. Ground reaction forces in the anterior-posterior direction F The forces of this component of the ground reaction are smaller than It is vertical and is about 25% of body weight. At the beginning of the stationary phase, this force causes the leading foot to brake or slip, and its value is negative in the first 50%, indicating that the person is pushed backwards, and at the end of the stationary phase, it is towards the front, and its value is positive. be And it makes progress forward. Timepoint: immediate. Method of measurement: Using Kistler's Force plate device, we ask the child to walk on the force plate once with normal shoes, once with thick sole medical shoes and another time with thin sole medical shoes. We measure the parameters of vertical forces of ground reaction, anterior, posterior and internal external forces of ground reaction which are recorded in the form of a diagram while walking in three test situations. • The amount of displacement of the center of pressure: • Theoretical definition: the value of displacement of the result point of the earth's reaction force • Applied definition: the number shown by the computer dynamic state device in centimeters related to the X and Y axes.
