The original study assessed 5 cold liquid swallows, which provided important information regarding the immediate effects of cold liquids on the pharyngeal swallowing mechanism in preterm infants with dysphagia. Further information regarding the duration of these positive effects is necessary to prove its reliability as a modification to be used at bedside. This study is designed to assess the swallowing mechanism of dysphagic preterm infants after feeding cold liquids for 10 minutes to objectively identify any changes over time.
