Early intervention programmes for preterm infants have a positive influence on cognitive and motor outcomes during infancy, with the cognitive benefits persisting into pre-school age. There is a great deal of heterogeneity between studies due to the variety of early developmental intervention programmes trialled and gestational ages of the preterm infants included, which limits the comparisons of intervention programmes. Further research is needed to determine which early developmental interventions are the most effective at improving cognitive and motor outcomes, and on the longer-term effects of these programmes.
The effects of the Rice infant sensorimotor stimulation treatment on the development of high-risk infants.
The Rice Infant Sensorimotor Stimulation (RISS) treatment was given to 15 premature infants to determine effects on neurophysiological development. The mothers of the infants were trained to administer the treatment for 15 minutes, 4 times a day, for 1 month, beginning the day the infant arrived home from the hospital. When each infant in the study (15 experimental and 14 control) was 4 months postnatal age, he/she was examined by a pediatrician, a psychologist, and a pediatric nurse who had no knowledge of which infant was experimental or control. The results indicated the experimental infants made significant gains in neurological development (p less than .001), weight gain (p less than .04), and mental development (p less than .05). The findings of this research indicate that early and systematic stimulation of the nerve pathways of the skin and of the vestibular nerve cells can accelerate growth and development of premature infants.
