Purpose The purpose of this study was to investigate the effects of sensory stimulation and oral motor exercise program on oral feeding and development in premature infants. Methods Eight of the experimental group had sensory stimulation and oral motor exercise and 7 control subjects who performed oral motor exercise alone. There are 15 people in total. They were randomly assigned to two groups according to the order in which they visited, through a random number table using a computer program. The mediation period was 5 days for 4 weeks, 20 minutes for the experimental group and 15 minutes for the control group. Results In the comparison of pre - and post - intervention effects between the two groups, amount of oral feeding, Weight, Neonatal Oral Motor Assessment Scale (NOMAS) jaw, and tongue grade showed significant changes in both groups. Comparisons of pre - and post - intervention changes between the two groups showed significant changes in the amount of oral feeding in the experimental group. Conclusion Both the experimental group with sensory stimulation and oral motor exercise and the control group with oral motor exercise program showed positive effects on oral feeding and development. The effects of oral motor exercise program and sensory stimulation intervention were more effective in increasing oral feeding than oral motor exercise alone.
