PAL® is a medical device that encourages and reinforces the development of non-nutritive sucking in premature infants. This is accomplished by giving positive feedback in the form of music/mother’s voice as an auditory input in direct response to efficient sucking.
When the infant achieves the sucking strength and duration level set by the caregiver, the infant will hear music/mother’s voice BUT only for the preset length of time set by nurse/therapist. To hear music/mother’s voice again, the infant must again suck at the preset strength and duration.
The positive reinforcement of the gentle, pleasant musical lullabies/mother’s voice encourages and reinforces the development of the infant’s sucking ability.
