AIM The aim of this unregistered evidence-based systematic review was to determine the state and quality of evidence on the effects of oral motor exercises (OME) on swallowing physiology, pulmonary health, functional swallowing outcomes, and drooling management in children with swallowing disorders.METHOD A systematic search of 20 electronic databases was completed to identify relevant peerreviewed literature published in English between 1960 and 2007. Experimental or quasi-experimental design studies examining OME as a treatment for children with swallowing disorders were appraised for methodological quality by two assessors and reviewed by a third.RESULTS Sixteen studies of varying methodological quality were included. No study examining the effects of OME on pulmonary health in children was identified. The included studies incorporated a wide variety of OME, and mixed findings were noted across all of the outcomes targeted in this review.INTERPRETATION Based on the results of this evidence-based systematic review, there is insufficient evidence to determine the effects of OME on children with oral sensorimotor deficits and swallowing problems. Well-designed studies are needed to provide clinicians with evidence that can be incorporated into the preferences of the client and the clinicians' knowledge of anatomy, physiology, and neurodevelopment in the management of this group of children.Swallowing disorders in children vary widely in terms of clinical presentation, etiology, severity, complexity, and impact on daily life. 1 These disorders range from transient and developmental to multidimensional and chronic or progressive. 2,3 For example, swallowing disorders are common in children with a variety of etiologies that include, but are not limited to, cerebral palsy (CP), genetic syndromes such as Down syndrome, and craniofacial anomalies. These swallowing disorders may involve multiple aspects of the feeding process (e.g. gathering food to the mouth, preparation, etc.), the swallowing process (e.g. bolus formation, oral phase abnormalities, impaired pharyngeal phase function, and reduced upper esophageal sphincter function), as well as difficulty with drooling or managing secretions. 4 Drooling (sialorrhea) most often occurs because of infrequent swallowing of saliva (secretions), and less frequently because of excess saliva production. 5,6 Moreover, these disorders may result in several health-related complications such as inadequate nutritional status and growth, reactive airway disease, and aspiration pneumonia. 7 Other children present with more mild developmental swallowing problems or oral-motor inefficiencies that may not have a negative impact on nutrition or overall health status. Although often considered less severe than other swallowing disorders, these oral motor disorders have been associated with dental malocclusion and mouth open resting posture. 8 Regardless of the etiology or severity, disruptions in the feeding and swallowing process may result in an increased burden to the caregiver, socia...
