Prematurity and infant stimulation: a review of research.

Morbidity risks continue to constitute a major problem for the premature infant, despite striking progress in neonatal care and technology. This article reviews the early stimulation literature over the past 15 years, and discusses the findings of improved weight gain, respiratory status and psychomotor development when infants are stimulated early in life. Although some authors have criticized this area of research because of methodological problems, the overwhelming evidence points to the beneficial consequences of tactile and vestibular stimulation programs in high-risk nurseries. Further research is, however, clearly indicated in order to more fully elucidate the major variables and mechanisms responsible for the experimental effects, and to elaborate a more standardized program of psychological care of premature infants.
