Behavioral treatment of feeding difficulties and tube dependence in children with cerebral palsy and autism spectrum disorder.

The reason we published this article is that a good thing about empirically-supported treatments for feeding difficulties is that they work regardless of the original cause, diagnosis, disability level, or tube status. Unfortunately, parents may be inappropriately told things like: their child couldn’t eat (or would never self-feed or chew, etc.; with a lack of assessment or treatment data to support this), ABA (applied behavior analysis; behavior-analytic treatment) is only for autism, for cerebral palsy (CP) they should automatically go to speech and OT (occupational therapy) instead, or ABA is for decreasing inappropriate mealtime behavior rather than teaching skills. Caregivers have reported thinking their child was not able to do treatment and asking if they are able to do the feeding program if they don’t talk or understand instructions; However, this treatment is tailored to each child’s level and needs and still works, and actually in the hospital we mostly saw toddlers (younger) with more developmental disabilities and medical problems. The thought should not really be ‘if’ they can learn it, but ‘when’ or what it will take. It may just take more time, especially to teach chewing and reach regular texture and full meal volumes, although still we’re just talking about weeks/months—not years. 

So, when may this treatment not be appropriate or enough? Here are some examples: if there are body image concerns (ie, eating rather than feeding disorders), if the child is NPO due to aspiration (medical team said child is unsafe to swallow as food or liquids may go into their lungs ie, ‘going down the wrong pipe’), uncontrolled seizures or pain, TPN (total parenteral nutrition; IV is going into veins instead of stomach). Some people may need a highly controlled expert hospital setting like KKI (Kennedy Krieger Institute) where this article was published if they are older in age or have aggression, self-injury, pica, rumination, etc. and more resources are needed.

Abstract

BACKGROUND:

Feeding disorders are multifaceted with behavioral components often contributing to the development and continuation of food refusal. In these cases, behavioral interventions are effective in treating feeding problems, even when medical or oral motor components are also involved. Although behavioral interventions for feeding problems are frequently employed with children with autism, they are less commonly discussed for children with cerebral palsy.

OBJECTIVE:

The purpose of this study was to compare the effectiveness of using applied behavior analytic interventions to address feeding difficulties and tube dependence in children with autism and children with cerebral palsy.

METHOD:

Children ages 1 to 12 years who were enrolled in an intensive feeding program between 2003 and 2013, where they received individualized behavioral treatment, participated.

RESULTS:

Behavioral treatment components were similar across groups, predominately consisting of escape extinction (e.g., nonremoval of the spoon) and differential reinforcement. For both groups, behavioral treatment was similarly effective in increasing gram consumption and in decreasing refusal and negative vocalizations. A high percentage of individualized goals were met by both groups as well as high caregiver satisfaction reported.

CONCLUSIONS:

Behavioral interventions for food refusal are effective for children with cerebral palsy with behavioral refusal, just as they are for children with autism.
