Children with developmental coordination disorder have significantly poorer motor coordination than children of the same age. The cause of this disorder is not known, but it is not caused by intellectual problems or brain damage. These children often have the perception of being “clumsy” and have difficulties with learning and daily living. Foreign studies have shown that the incidence of developmental coordination disorder is 5-8%, with boys accounting for the majority, 75-85%, and no incidence has been reported in China. Children with developmental coordination disorder are born with inadequate balance and uncoordinated arms and legs. Due to lack of awareness of this disorder among parents and teachers, children are not diagnosed and trained early, resulting in serious impairment of academic, social, emotional and self-image. Parents should pay attention to its early warning signs, train early, and get children trained appropriately as early as possible to make significant progress in familiar physical activities and daily life. 1. Milestone motor development indicators are lagging behind. The so-called milestone motor development index means that a normal child will lift his head at two or three months, roll over at four months, sit at six or seven months, crawl on his stomach at eight or nine months, and crawl at four points at ninety months. The corresponding action to the time but still can not do, it suggests that there may be abnormal. 2. The quality of the completed movement is poor compared to that of children of the same age. For example, at a certain age, although the child can sit and stand, but from the sitting position to the standing action, without assistance can not be; Another example is that obviously can sit, but if it is lying down, lying position, they can not sit up. This shows the lack of ability to change movements. 3. The ability to learn skillful movements is poorer than that of children of the same age. For example, grasping and pinching objects, waving goodbye, etc. The child’s imitation ability is poor and the movement is inflexible.
