Children in the 3-12 years of age, the arch bone is in the development period, is the golden period of arch formation, if improperly wearing shoes or too obese and poor sitting posture, affecting the normal development of muscles, ligaments and bones, most lead to flat feet, inward eight, hindfoot inward and outward, X-leg and other foot diseases. Foot friends of children’s skeletal gait correction cushion, Lixing Tiandi corrective shoes, corrective insoles using the principle of human biomechanics, the foot arch scientific support, so that the normal development of muscles, ligaments, bones, so that the arch bone orderly arrangement, to help children grow up healthy. In our daily study and life, once found inside or outside the octagonal foot, should pay attention to timely correction, if a parent party itself is inside or outside the octagonal foot, must pay close attention to the child’s walking and running posture, found the problem, timely correction. 1, first of all, to strengthen the legs, foot arch and ankle strength exercises. For example: in situ feet together upward lifting stirrups practice, in situ or marching high leg running practice (amplitude, speed mastered by themselves). 2, master the correct technical movements of running, and under the guidance of the teacher, repeatedly practice the correct technical movements, so that the movement to achieve power stereotypes. a. Give the child the correct step pattern, the adult counted the password, let the child slowly step on the beat walking. The number of times a day, the number of steps and time to practice, according to the extent of the child’s foot deformity and the formation of the length of time depends on the gradual progress. b. Straight line stepping method. Draw two straight lines on the ground about 10-15 cm apart, so that the child’s toes and heels are walking back and forth in a straight line, the pace from slow to fast. This conscious training, persistent effect will be very good. c. Straight line running method. Pull a bright plastic tape on the ground or draw a straight line with colored chalk, let the child stand with feet parallel on both sides of the straight line, under the command of adults let the child walk along the straight line, walk do not let the child appear eight feet. 3, due to the influence of the living environment and produce internal and external eight feet of students, pay attention to the development of the corresponding muscles. For example, do some exercises of internal rotation, external rotation of the thigh and hook the back of the foot to do by internal rotation, external rotation of the ankle exercises. 4, due to habitual movements and the formation of the external eight feet, in ordinary daily life, should be consciously correct the habit of external eight feet; and internal eight feet, can participate in the basic dance training. Such as doing leg press exercises: one foot support, the other foot straight in about 80 cm high pole for the front leg press, requiring the leg pressed toe external rotation. 5, choose a professional foot orthotic device within the eight corrective shoes, children’s corrective shoes, corrective insoles within the eight or outside the eight, can already be corrected through biomechanics, only need to wear professional children’s corrective shoes, pay attention to the running posture, walking posture and with the auxiliary exercise provided by professionals, is very good to help children restore health.
