Early intervention includes both preventive and rehabilitative components. The intervention is preventive in nature through family intervention that starts after discharge from the hospital, promoting the acquisition of developmental milestones through massage, passive gymnastics, and active motor training (practicing prone head lifting, rolling over, pulling sitting, vertical head and hand grasping according to the age of the month). In the process of follow-up and intervention, doctors regularly do neuromotor examinations, and when suspected cerebral palsy symptoms are detected early, intensive rehabilitation training can suppress and eliminate abnormalities in muscle tone and posture, thus enabling the child to develop normally. For children who are likely to develop cerebral palsy or mental retardation, early intervention means that rehabilitation starts when symptoms of cerebral palsy are suspected. This is the only way to achieve good results. The meaning of “early intervention” includes both early and intervention. The earlier the intervention, the better. Premature and high-risk infants should start from birth. There are two meanings of “intervention”: 1. The method of intervention is to carry out organized and purposeful educational activities in an enriched environment according to the law of infant and toddler intellectual development, i.e., using tactile, visual, auditory, motor proprioception and vestibular balance, to promote infant and toddler intelligence and motor development, to promote the acquisition of developmental milestones, and to reduce developmental risks. risk. The other condition is when cerebral palsy or intellectual development is detected, which has the advantage of directly targeting dysfunction and applying only to selected populations. This condition can be directly referred to as “rehabilitation”. However, there are risks, especially in cerebral palsy. Therefore, early intervention includes both prevention and rehabilitation, and can be understood as two different stages of the same process for children who later show specific neurodevelopmental abnormalities requiring special treatment programs (physical, speech, cognitive, educational, behavioral rehabilitation).
