O-leg, medically known as “inversion of the knee”, commonly known as “loopy leg”, “bow leg”, “basket leg “O-leg. This refers to the fact that at the knee joint, the shin bone of the lower leg is rotated inward at an angle, so it is called “inversion of the knee”.
When the ankle joints are together but the knee joints are not, the distance between the knee joints should be measured, and when the distance exceeds 4cm (or the distance between the knees is equal to or more than the width of two fingers), it is considered excessive and is called inversion deformity and needs to be corrected. Of course, O-leg is still very aesthetic even if it is not serious.
I. What are the causes of O-leg formation
The formation of O-leg is mainly due to developmental factors and imbalance factors.
1, developmental factors: During the period of body development, because of malnutrition or intestinal diseases, caused by calcium and phosphorus and other nutrients deficiency, bone development disorders, bone deformation or joint cartilage dysplasia, thus appearing knee inversion.
2, imbalance factors: because of long-term poor posture or incorrect force habits, causing an imbalance in the muscle mechanics governing the joint, long-term imbalance in muscle mechanics can lead to joint displacement, resulting in the formation of internal knee roll.
Walking outwardly, standing in a resting position, wearing high heels for a long time, sitting, kneeling, squatting, etc., will give the knee joint outward force, and this force will pull the lateral collateral ligament of the knee joint, which will lead to the relaxation of the lateral collateral ligament of the knee joint in the long run.
Second, what is the harm of O-leg
O-leg is also likely to lead to knee osteoarthritis or disorder of the lower limb force line, which will affect the position of the patella on the femoral joint surface and lead to abnormal patella wear; and the abnormal force line of the lower limb will also affect the mechanical balance of the body, leading to the discomfort of the lumbar spine and even affecting the cervical spine in other parts of the body, such as lumbar compensation.
Third, how to correct O-leg?
1, towel thin thighs: the whole body standing straight, legs together as far as possible, with the inner thighs of the thick stack of towels, the left and right feet to “d” standing, each other into 90 degrees at right angles, while the arms up straight, stretching the whole body, exercise thigh muscle strength, but also correct O-leg.
2, heel lift: legs together and knees shallow sitting on a chair, thighs and calves into 90 degrees, the palms of the feet forward, hands stacked on the thighs. Then stand on tiptoe with the back half of the foot separated from the ground and the toes on the ground, while paying attention to the force applied to the legs and the muscles tightened.
After the feet are on tiptoe, further straighten the legs so that the rear part of the feet and calves are in a straight line, perpendicular to the ground, and the center of gravity falls on the toes.
3, toe clip beads: extend the legs, the palms of the feet straight forward, so that the back of the foot and calf into a straight line, a glass bead placed under the toe, between the thumb and the second toe, and then toe force bending clamping glass beads, maintain the posture, so that the glass beads do not fall.
4, toe push pressure: lift the leg, the heel on the thigh, try to open the toes, and then press the toes backward with the fingers, pay attention to the strength to moderate, so as not to sprain the toes.
5, standing posture: the correct standing posture is also very good thin legs movement, legs as close as possible, the right leg in front of the ground left and right feet into a “d” standing, the upper body straight, and the lower body into a straight line perpendicular to the ground, not leaning forward not back, arms hanging naturally by the side, head up and chest.
When standing, the whole body weight falls on the toes on the ground, so the toes must be stretched out in the shoes, if bent or contracted, the body is prone to imbalance, resulting in the displacement of the lower body bones. The right and left feet into a “d” shape, the heel of the right foot is attached to the left foot inside the ankle side.
Many women like to stand inside eight, which will make the pelvis contracted inward, improper muscle distribution leads to imbalance, resulting in the O-leg is also very common.
6, walking posture: walking in high heels is very different from flat shoes, the key is the high heel and forefoot at the same time, followed by the step when the knee is almost not bent. Also note that when stepping, after landing, the back leg off the ground 3 steps of the transfer of gravity from back to front.
When walking, pay attention to the legs do not separate to walk, keep the palms of the feet slightly outward, between the feet along a straight line to step forward.
7, sitting posture: knees bent together shallowly sitting on a chair, legs naturally placed one in front of the other, the palms of the feet slightly outward, the right heel against the inside of the left foot, arms naturally bent on the thighs, the upper body straight, head up and chest out.
From the side contrast, the magnitude of the right foot out in front also has to be careful, oh, the inner ankle and knee level distance to maintain at about 10cm. Straighten the back and leave the backrest of the chair, 1 fist apart. Legs to the chair under the collection, waist and back completely leaning on the chair is a big taboo!
