Oral-motor skills refer to the movement of the muscles of the face and oral area (e.g., mouth, jaw, lips, tongue, soft palate). These skills are influenced by muscle tone, muscle strength, range of motion, speed, coordination, and dissociation (the ability to move oral structures, such as the tongue and lip, independently of each other) (Kumin n.d.). Clinical experience suggests that the acquisition and maturation of oral-motor movements underlie sound production and feeding skills (e.g., sucking, biting, and chewing) (Arvedson and Brodsky 2002). Children with developmental disabilities may demonstrate oral-motor patterns that are not observed in typical development. Atypical oral-motor patterns include jaw thrusting, tongue thrust, tonic bite reflex, lip retraction, tongue retraction, and nasal regurgitation (Morris 1978). A child’s oral-motor skills may be assessed by a speech-language pathologist.
