If the child’s development at all ages is the same as that of a normal child, it is unlikely to be cerebral palsy. To rule out cerebral palsy, we need to compare with children of the same age group. There are several criteria for diagnosing cerebral palsy: first, whether there is any motor backwardness, abnormal motor posture, walking differently from others, grasping objects differently or sitting differently; second, whether there is any abnormal muscle tone, whether the child’s limbs are usually found to be too hard or too soft, or whether the child’s movements are irregular, uncoordinated, or asymmetrical; third, mainly If the child has no obvious abnormalities, cerebral palsy can be ruled out.
