Abstract
Behavioral techniques for the remediation of velopharyngeal insufficiency appear to be widely used in the clinical domain, but their efficacy has not been demonstrated empirically. This paper provides a physiologic rationale for the use of palatal training procedures by discussing literature on strength training and neural adaptation, and the mechanisms for sensorimotor control in the velopharyngeal mechanism. A direct palatal training method that has shown clinical promise, CPAP therapy, is described.
