Abnormal postural reflex activity and voice usage deviations in cerebral palsy.

A relationship is considered between abnormal postural reflex activity and its effect on vocal processes in infants and very young children having cerebral palsy. Neurodevelopmental treatment concepts are interpreted as they may apply to evaluation and intiial management of hypertonic children who exhibit voice usage deviations. Interdisciplinary team function in the areas of physical therapy, occupational therapy, and speech pathology is suggested.
