Abstract:
Packing involves not swallowing solids or liquids in the mouth. It is a significant mealtime behaviour to treat. Research has shown effectiveness of redistribution, but only two studies in highly specialised hospital settings in the United States have evaluated the use of a chaser. We extended this literature by conducting treatment in the home setting, and comparing a liquid and puree chaser separately to infant gum brush redistribution and a move-on to the next bite presentation component. A 4-year-old male with autism spectrum disorder and gastrostomy tube dependence participated in his home. We used a multielement single-case experimental design. With the liquid chaser, consumption increased to 100%. Swallowing latency was significantly lower with the liquid chaser compared to other packing treatments.
