Effectiveness of Oral Sensorimotor (Oral Motor) Interventions for Pediatric Feeding and Oromotor Dysfunction: A Systematic Review of Randomized Controlled Trials

Context: Oral sensorimotor/oromotor interventions (oral motor therapy, OMT) are used to improve oral-phase feeding function in preterm infants and children with neurodevelopmental disorders, but the evidence is heterogeneous. Objective: To evaluate the effectiveness of OMT on oral feeding performance and oromotor outcomes in paediatric populations. Evidence acquisition: We searched Scopus, Web of Science, ProQuest, and PubMed for randomized controlled trials (RCTs) evaluating oral sensorimotor/oromotor interventions in infants and children (0–18 years). Data were extracted using a standardized form and synthesized narratively. Results: Six RCTs (n = 467) were included. In preterm infants, interventions such as PIOMI and NICU oromotor programs improved feeding readiness and feeding efficiency. In children with cerebral palsy, allied health–led OMT (including app-based and neuroplasticity-oriented programs) improved oral motor function, feeding ability, and caregiver-related outcomes. Limitations: Considerable heterogeneity in interventions, outcomes, and follow-up; several trials had methodological limitations and small sample sizes; English-language restriction. Conclusions: OMT shows potential benefit in selected paediatric groups, especially preterm infants and children with cerebral palsy. Because the certainty of evidence is limited, OMT should be implemented within multidisciplinary feeding pathways, consistent with local competency and scope of practice.
