Early intervention consists of providing continuous multidisciplinary services to infants from birth throughout the first year of life. It means intervention therapy specified for babies at risk for developmental delay and periodic developmental assessment of motor, cognitive function, language/adaptive functioning. Early interventions promote child health, minimize developmental delays, improve existing disabilities, prevent functional deterioration, and promote parent-child interaction. Early intervention (EI) consists of multidisciplinary services provided to infants from birth through the first years of life to promote child health, enhance emerging competencies, minimize developmental delays, cure existing disabilities, prevent functional deterioration, and promote adaptive parenting functioning. These goals are accomplished by individualized developmental, educational, and therapeutic services. An increased number of investigations have studied the effects of EI on the behavior and development of high risk infants (mainly premature infants with low-birth-weight) based on the rationale that premature infants are at risk for neurological and psychological disabilities.
