Effects of vestibular-proprioceptive stimulation on the neurobehavioral development of preterm infants: a pilot study.
This paper reports the results of an intervention study which assessed the effects of compensatory vestibular-proprioceptive stimulation provided by waterbed flotation on the neurobehavioral development of preterm infants. The subjects, who were randomly assigned to experimental and control groups before they were four days old, consisted of infants who were on ventilators for severe RDS. Twenty infants were tested with a new neurobehavioral assessment procedure when they were between 34 and 35 weeks conceptional age. The examiner, a pediatric neurologist, was unaware of the group status of the subjects he examined. The results showed that infants in the experimental group performed significantly better in attending and pursuing animate and inanimate visual and auditory stimuli, demonstrated more mature spontaneous motor behavior, showed significantly fewer signs of irritability and/or hypertonicity and were more than twice as often in th visually alert, inactive state. The assessment procedure, which can be used for longitudinal evaluation of infants ranging between 24 and 36 weeks conceptional age, shows promise of becoming generally useful as a research instrument. Our preliminary results show that the procedure discriminated between an experimental and control group, that inter-observer reliability was readily established and that test-retest reliability is very high in a number of important areas of neurobehavioral functioning.
