Because of the lower limbs of eight inside the internal rotation for a long time, the growth of muscles and bones is affected by the position that occur within the femoral rotation, adduction contracture, tibial internal rotation, these internal rotation and adding to the foot. Of internal rotation and adds to the lower limbs in position. Within these interact with each other, and make eight words is becoming more and more serious. Femur internal rotation, adduction contracture, tibial internal rotation may cooperate with corresponding problems such as family rehabilitation training, to improve, at the same time outside of eight orthopedic shoes to wear with correct ankle problem and achieve the best orthopedic effect. Training plan: 1, outside of eight bits stand: let the children stood back against the wall, feet outside the horoscope, heels together, tiptoe to eight direction, remain as far as possible is a word, it is best to stick to more than 15 minutes. So that we can make the child out of lower limb, the improvement of the internal eight has very good effect. 2, passive breaststroke movement: child supine, legs bend your knees hip flexion, parents holding the knee, hip joint as the center of the circle, to do the knee up and then outward down first leg circle action ( Similar to the breast stroke action) For the legs to the outside of the time, the child of the knee joint as far as possible close to the bed surface. Operation skill points: the movement wants gently, step by step, do not let the child too pain, so as not to pull a muscle. Correct shoes custom-made center adopts the international first-class testing equipment, technology and production line, the earlier to the foot of the 3 d scan and foot pressure analysis, gait analysis, 3 d printing last, 3 d printing insoles, shoes design personalized correction software, and a series of world advanced foot orthodontic treatment technology is introduced into China, the product production equipment and technology and the first-class level of synchronization, North America and Europe for nearly a decade has become a domestic foot correction field vane, for the majority of patients to provide the world-class products and services.
