Speech performance, dysphagia and oral reflexes in cerebral palsy

Abstract

The adequacy of biting, sucking, swallowing, and chewing as well as the presence or absence of nine infantile oral reflexes were assessed in 60 cerebral-palsied individuals. The effect of the asymmetric tonic neck reflex and the Moro reflex on the infantile oral reflexes was also studied. There was a trend for subjects with more adequate feeding skills to achieve higher levels of overall speech proficiency and articulatory competency, but this trend was not completely systematic. Fifteen subjects displayed abnormal oral reflexes, but these reflexes could not be elicited consistently. The effect of the ATNR and Moro reflex on the oral reflexes seemed limited. Results generally supported the value of the widespread prescription of improving feeding in cerebral palsy, but the need to modify abnormal oral reflexes received less support. The question of using prespeech oromotor training to reduce possible future dysarthria is discussed in terms of the findings.
