The purpose of this research was to review the evidence related to determining whether oral stimulation versus orocutaneous stimulation has a more prominent effect on the non-nutritive suck and overall oral feeding progression of pre-term infants. A comprehensive literature, electronic, and hand search was conducted to find relevant, peer-reviewed articles published between 1995 and 2014. Articles that met the inclusion criteria were appraised for quality and categorized based on intervention technique. Ten studies were included and focused on oral stimulation (five) for orocutaneous stimulation (five) on pre-term infants and effects they had on oral feeding progression. This review reveals that oral stimulation only has positive effects on parts of the NNS, while orocutaneous stimulation showed promising results toward the overall progression of NNS and independent oral feeding.
