Description:
This is a review of experimental, quasi-experimental, or multiple-baseline single-subject design research investigating the effects of oral motor interventions (OMI) on outcomes of feeding and swallowing for preterm infants.

Question(s)/Aim(s) Addressed:

  1. What is the effect of OMI on feeding and swallowing physiology (e.g., sucking pressures, feeding efficiency, rate of liquid transfer, aspiration, or total length of feeding time) in preterm infants?

  2. What is the effect of OMI on functional oral feeding and swallowing outcomes (e.g., volume intake, days to oral feeding, weight gain, or growth) in preterm infants?

  3. What is the effect of OMI on pulmonary health (i.e., aspiration pneumonia) in preterm infants?

Population:
Preterm infants.

Intervention/Assessment:
Oral motor interventions.

Number of Studies Included:
12

Years Included:
1960 to 2007

Conclusions:

Pediatric Dysphagia

  • Treatment

    • Oral Motor Interventions

      • “Non-nutritive sucking (NNS) has been the most extensively studied [oral-motor intervention], with strong positive findings for improvement in oral feeding and swallowing physiology variables and for reducing the time to transition to total oral feeding by some investigators” (p. 337).

      • “Pre-feeding stimulation has been explored in fewer studies, with equivocal results across the outcomes targeted in this review” (p. 337).

      • “Although less thoroughly investigated than NNS in isolation, the combined effect of NNS plus oral stimulation produced a similar pattern of findings to NNS alone” (p. 337).

      • “None of the OMIs provided consistent positive results on weight gain and growth in this population” (p. 337).
