Conditions

flexible flat foot. Congenital pes planus

Interventions

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

Measure	Time frame
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 i	—
