1, what is a flat foot?
Flat feet are mainly caused by abnormal bone morphology, muscle atrophy, ligament contracture or chronic strain, which leads to the collapse of the longitudinal arch of the foot or the disappearance of elasticity.
2. The causes of flat feet
The main reasons for flat feet include the following:
1, genetic factors;
2. Congenital foot bone deformity;
3. Foot trauma or chronic strain;
4. The medial muscle or lateral muscle of the foot is weak or paralyzed and spasmodic.
5, the outer eight characters;
⑥ heel valgus;
7. x-shaped legs;
8. Hallux valgus;
9. Obesity;
10, senile organism degenerates;
1 1, bones grow too fast during development;
12, malnutrition;
13, penetrating hard bottom for a long time.
3. Can flat feet be inherited?
From the above reasons, we know that heredity is also one of the causes of flatfoot, so some flatfoot patients are hereditary.
4. Genetic probability of flatfoot
Flat foot is not 100% hereditary disease, but it belongs to general dominant inheritance. Many people have this disease together, and children are easy to inherit.
Severe patients with flat feet will affect normal running and even walking. However, some people will worry that the disease is related to heredity, so is flatfoot really hereditary?
5. What about hereditary flat feet?
If you find that you have a genetic tendency, you should often practice walking with the outer edge of the sole of your foot. Physical therapy is also effective in the early stage. The specific methods are as follows: walk on tiptoe and bend on tiptoe. In addition, you can wear a flat-footed insole or a flat-footed orthopedic shoes to raise the inside of the heel and make the load-bearing line move outward, thus preventing and reducing foot fatigue.
6, flat foot correction principle
(1) Proper exercise
Exercise is very important for the healthy development of children's feet. In recent years, the problem of children's flat feet has increased by about 20% compared with the 1980 s, which is obvious. One of the main reasons is that children lack exercise. Children should do more sports, such as toe exercise, toe catching glass ball exercise, skipping rope, playing basketball, etc., in order to improve the strength of foot muscles and ligaments and promote the development of arch. In addition, parents should also pay more attention to their children's usual posture, especially children with "inner splayed" feet or X-legs, as well as children who like to sit on their knees and sit in a W-shape. Parents should help them develop correct posture, thus effectively reducing the sequelae caused by children's foot function problems.
(2) Choose shoes correctly to prevent sequela.
There should be different nursing methods for each stage of children's foot growth. Teacher Wu Kunying, a teaching consultant and part-time professor of prosthetic orthopedic course in Zhongshan School of Medicine, Sun Yat-sen University, suggested that parents should choose suitable healthy shoes for their children, which is especially important for the healthy growth of their feet. Children wearing suitable shoes and insoles can reduce the chance of foot sequelae and ligament damage. He added that healthy shoes should have the following elements:
1), with arch pads of different ranges to relieve arch fatigue and prevent sequelae of flat feet;
2) There is a hard heel cup to stabilize the heel bone and control the eversion of the hind foot;
3) The forefoot has different girth choices to prevent the forefoot from being too loose or too tight, and to increase the comfort of the foot;
4) Shape the midsole to help stabilize the foot shape and strengthen the support of the insole.
(3) Shoes and socks with good warmth retention
Such as cotton shoes, towels, socks, etc., are warm and comfortable, and are very suitable for children to wear. However, sports shoes, rubber shoes and leather shoes are not suitable for wearing because of their poor thermal insulation performance, rapid heat dissipation and easy freezing of feet. The size of shoes and socks should be slightly larger, and there should be a slight gap between feet and shoes to facilitate air isolation and increase warmth.
(4) Change and dry shoes and socks frequently.
Children are active and their feet sweat easily. It is best to place insoles in shoes to absorb moisture and sweat to reduce heat dissipation, and change the sun frequently to ensure that shoes are dry and warm. Shoes and socks should be replaced in time when they are wet in rain and snow.
(5) Soak your feet with hot water every night.
Wash your feet with warm water before going to bed every night, and cover your feet after lying down. This can prevent children's feet from catching cold, prevent colds, help children fall asleep faster, and is also of great benefit to improving sleep quality.
