Background: Oral sensory motor stimulation is one of the widely strategies used for preterm neonates to improve oral feeding skill. purpose: purpose of the study is to assess the effect of oral sensory motor stimulation on short term clinical outcomes for preterm neonates. Design: Aquasi-experimental design was utilized. Setting: The study was conducted at Neonatal Intensive Care Units at Benha University Hospital. Sample: A purposive sample of 100 preterm neonates. A simple random sample was done to assign them into two groups, study group included 50 preterm neonates and control groups included 50 preterm neonates. Instruments: Two Instruments were used. Instrument one, A structured questionnaire sheet, Instrument two,  Preterm clinical outcomes measurement sheet. Results revealed that, Length of hospital stay was significantly less in the study group than in the control group P-value Conclusion: Applying oral sensory motor stimulation had a positive effect in improving feeding performance, weight gain, and decrease length of hospital stay for preterm neonates. Recommendations: Oral sensory motor stimulation should be administered as integral part of routine daily care at Neonatal Intensive Care Units.
