Treatment should be individualized to the child. One treatment method may be appropriate for one child but not another. Typically, I approach treatment for CAS from a motor learning perspective, making sure to address linguistic aspects of the disorder as well. We focus on training muscle movements. I wrote a workbook containing targets for specific muscle movements (i.e., CVC targets bilabial sound to alveolar sound, CVCV targets velar sound to palatal sound). I utilize tactile cues, visual cues, visual cue cards, and phonemic cues. The child and/or child's parents and I brainstorm a list of words specific to the child to target as well. This list would contain names, favorites, common requests, and anything the child might need to say on a frequent basis. Whether or not I use massed practice/distributed practice/knowledge of results/knowledge of performance depends on the accuracy of the specific target. Each child is different as is their accuracy of individual targets. Each treatment session requires a mini evaluation of the child's performance to determine where to address targets as well as what cues and treatment method to use.
