Young children love to ride children's tricycles. However, there are a large number of children who often ride on children's vehicles. The lower limbs are all "X" shaped differently. Why is this? It turns out that most of them often ride children's tricycles from the age of 3 to 4 years old.
Children's bones are in the development stage, their plasticity is very strong, and their muscle strength is very weak. When they ride a buggy, the lower limbs require a lot of effort. In addition, because riding a buggy is fun, the child does not want to come down on a ride. In this way, the leg is in a state of muscular tension for a long time, and the skeleton of the lower extremity is also subjected to stress for a long time, which is very unfavorable to the growth and development of the skeleton. In addition, children's tricycles currently on the market have a wider distance between the two pedals, and the distance between the seats and the pedals is too long, and some vehicles cannot adjust this distance. In this way, when the child rides up, the feet and lower limbs are very hard. Over time, the introversion of the inside of both knees is formed. The two lower limbs expand outwards to form an "X"-shaped leg. Some children even form an internal octagonal foot.
