In daily life, some behaviors of children are often not noticed by parents, which is extremely detrimental to the healthy growth of children. Under normal circumstances, children grow to 1 to 1.5 years old can gradually develop from walking with objects to walking independently and smoothly. In order to prevent falls, children often walk with their feet apart to keep their center of gravity down and stable, a phenomenon that lasts until about 3 years old. We especially remind parents that they should carefully observe the walking gait of children in daily life, children who can already walk alone, if there are gait abnormalities, often suggest the existence of certain diseases, do not be careless, should be diagnosed at an early stage to the hospital, because children with abnormal gait is often the result of disease. 1, limping gait: the most common for children to avoid painful limp, often in the absence of obvious trauma walking abnormalities, complaining of pain on the affected side of the knee or thigh, which is often a temporary manifestation of synovitis. Incomplete paralysis of one lower extremity can also be caused by poliomyelitis or enterovirus infection. The child’s limbs move normally before the onset of the disease, but only after the onset of the disease does one limb become paralyzed and cause lameness. In contrast, congenital lameness is often caused by unilateral hip dislocation, and one lower limb lameness appears after learning to walk, while lameness is often elevated lameness. 2, eight-letter gait: there are internal and external eight-letter, which is very common in urban children, often causing concern to parents, which is caused by many of the force line of the lower limbs is not good. In addition, many of them have “0-leg” or “X-leg”, which is a clinical deformity of inversion or valgus of the knee. 0-leg, when standing, both ankle joints are close together and the knee joints are clearly separated; while X-leg, both knee joints are close together and the two ankle joints are clearly separated. In X-leg, the knees are close together and the ankles are clearly separated. Both of these manifestations are sequelae of rickets. There is also a common disease of walking out of the eight steps is hip contracture, this patient’s gait is more obvious when walking fast or running, jump-like. 3, scissor gait: when the child stands or help walking, the waist and back straight, two toes on the ground, both knees rubbing against each other, or even both legs completely crossed, scissor-like, serious arm movement is also restricted. Most of them are caused by brain underdevelopment, which can easily cause cerebral palsy neonatal hypoxic-ischemic encephalopathy, and the main symptom of cerebral palsy caused by it is scissor-shaped gait. 4. Duck gait: Children walk like ducks, with their chests protruding and their lower limbs moving slowly forward. If the child accidentally falls to the ground, he or she has to adopt a special posture to get up, i.e., first propping up the ground with both hands, bending over, then propping up both hands on the knee joints, and then gradually rising up with a straight back. In addition, there is also a common disease of developmental hip dislocation on both sides, whose performance is also combined with obvious posterior protrusion of the hip. 5. Tiptoe gait: Children walk or stand on their heels without touching the ground and stand on their toes. Common in children with clubfoot, some children are congenital clubfoot, some children are caused by neurological diseases, such as cerebral palsy, spinal cord spinal membrane bulge, spinal cord embolism, etc. 6. Drunken gait: After the age of 2, children also appear to walk unsteadily, bumping east and west, swaying from side to side or tilting to one side, just like the gait of adults who are drunk. It is mainly seen in children with cerebellar diseases, such as cerebellar tumors, inflammation or congenital cerebellar hypoplasia.
