Which of the following is a motor-based cause of pediatric feeding disorder?

Motor-based causes of pediatric feeding disorders are related to the physical capabilities and functions required for feeding, such as the ability to chew, swallow, and maintain appropriate posture during feeding. Posture is crucial because it directly influences a child's ability to control their oral motor movements and manage the process of eating.

When a child is seated in an appropriate posture, it facilitates proper alignment of the head, neck, and torso, which is essential for safe swallowing and preventing aspiration. If a child has postural difficulties, such as slouching or leaning excessively, it can hinder their ability to eat effectively, leading to feeding challenges.

In contrast, picky eating behavior may stem from behavioral or sensory issues rather than motor problems. Gastrointestinal difficulties primarily relate to the digestive aspects of feeding rather than the motor skills involved in eating. Pain associated with eating can also affect a child’s willingness to eat but is more related to sensory or emotional aspects rather than the mechanical processes of feeding. Thus, posture stands out as a direct motor-based cause of pediatric feeding disorders.
