First, congenital genetic factors. One of the parents is an inner character or an outer character, and the child born is probably one of them.
Second, the strength of the legs and ankles is insufficient. This phenomenon is especially obvious in sprint. In order to run fast, some students pushed back desperately and turned their feet inward or outward involuntarily.
Third, I didn't master the correct posture of running or walking.
Fourth, the influence of living environment.
Fifth, students who have participated in basic dance training also have splayed feet.
Sixth, the reasons for the formation of splayed feet should also be discussed when children begin to learn to walk. Some mothers measure their babies' intelligence by the time they can walk, so they are anxious to let them learn to walk. Because the baby's body is in the development stage, the feet are not strong enough. When walking and standing, the feet will naturally separate, so that the sole area will be widened to increase the strength to prevent falling, resulting in the posture of naturally separating the feet.
Seven, it is unscientific to let the baby wear hard shoes during the toddler period. Because children's foot bones are soft, ankle strength is weak, and leather shoes are hard and heavy, the baby has a feeling of "immobility" to shoes, which distorts the gait over time. Remind mothers that wearing cloth shoes is the best choice when they are toddlers.
Eight, due to the lack of calcium in the baby's body, the low calcium content in the bone itself, coupled with the pressure on the bone when walking and standing, it is easy to make the bilateral iliac joints appear outward, forming an "external figure" foot. Therefore, mothers should be careful not to let the calcium-deficient baby learn to walk too early, and provide their children with enough food rich in protein, calcium and vitamin D in time. Going outdoors to bask in the sun helps to absorb calcium and prevent rickets.
Nine, football players, due to long-term serious wear and tear of knee joints and ankles, are also an important reason for their external character.
X. other external causes.
Treatment:
Squat method, people with splayed feet stand with their feet rotating outward; People with splayed feet stand, with their feet turning inward, doing squats and standing.
Vertical jump, leg jump can correct the inner splayed foot, and cross-legged jump can correct the outer splayed foot. Or play football, sandbags and other things in a way that the outside or inside of the foot is constantly upward.
Leg rest method: put one leg on a horizontal plane, first relax the joint ligament of the lower limb, and stretch your hands after about 10 minutes. People with splayed feet pull outward, while people with splayed feet pull inward.
In the straight step method, two straight lines are drawn on the ground, and the distance between the two straight lines becomes a horizontal fist, which requires the heels and toes to step on the straight lines, and the pace is from small to large, from slow to fast.
Straight-line jumping footwork: Pull a rope on the ground so that the soles of your feet are parallel to the rope, or you can run along the drawn straight line. You are required to step on the line at every step, with your knees and toes facing forward and not deviating. It is worth noting that when doing various postures, we should pay attention to the direction of toe extension. If it is an "internal splayed foot", pay attention to the toes sticking out; If it is an "external splayed foot", try to extend your toes inward. Keep your knees and ankles in a straight line, especially when doing leg lifts, squats, jumps, etc. And the toes should consciously aim at the direction of progress and move along a straight line. We should also pay attention to the correct posture of sitting, standing, walking and running. As long as we pay attention to it and persevere, we will certainly achieve the goal of correction. The way of walking outside the eight characters can also be corrected through deliberate correction in daily walking, but it takes a long time and great perseverance to insist on completing the first deformation exercise with military posture and walking along the floor line with positive steps!
Wear children's corrective shoes to make the foot stress normal and balance at three points. At the same time, the reaction force on the ground is reduced.
At the same time, surgical fixation can be considered, but it is not absolutely normal, depending on whether you are a knee joint or a lower limb long bone deformity.
Cui Qingguo acupotomy can treat O/X leg.
Specific to everyone's situation, you need to consult and confirm in person.
