Cerebral palsy exclusion methods: 1. by asking medical history, that is, to see if the child has, for example, premature birth, cerebral hypoxia, intrauterine infection, intrauterine asphyxia, abnormal functional development; 2. at birth, there is no asphyxia, hypoxia, difficult birth; 3. after birth, there is no jaundice, early infection, pneumonia, encephalitis; 4. the child’s motor development is backward to exclude, for example, due to improper parental care, such as holding too much, not giving the child self-development The child does not have the opportunity to sit, crawl, stand, etc. Exclude whether the child has altered muscle tone. One of the things that can happen in cerebral palsy is a change in muscle tone, such as too high or too low muscle tone. A routine test is to see if the child’s joints are restricted in movement and if the muscles are tense or too floppy. This can be done by going to the hospital for a formal examination. It is also important to check for abnormal postures, such as tiptoeing, foot valgus, external rotation, inversion, internal rotation, etc. Some children are congenitally deaf and can’t hear, so they can’t communicate with others normally.
