The causes of motor retardation in children are broadly divided into the following three major causes: i. Intrauterine factors, children are affected by the mother’s body in the fetus, the mother has a miscarriage or is affected by physical, chemical and other drug factors, which can lead to the child’s developmental delay in the fetus. Factors during childbirth, such as hypoxic-ischemic encephalopathy, can lead to delayed motor development in children. Postnatal factors, such as bilirubin encephalopathy, can lead to motor retardation in children after birth. Once a child is diagnosed with motor delay after birth, he or she should be actively trained in motor rehabilitation behavior under the guidance of pediatricians and rehabilitation doctors. At the same time, oral or injections of neurotropic drugs can be used to reduce the future sequelae of motor delay.
