Motility Dysfunction

Overview:

Motility dysfunction refers to abnormal muscular activity in the esophagus or pharynx that affects the propulsion of a swallowed bolus. It may present as delayed clearance, retrograde flow, or uncoordinated contractions and is often identified through manometry or videofluoroscopic studies. SLPs recognize signs of motility dysfunction during dysphagia evaluations and refer for gastroenterological testing when appropriate. Treatment focuses on posture, diet modifications, and compensatory swallowing techniques. Addressing motility issues is crucial for safe, efficient deglutition and prevention of complications such as aspiration or malnutrition.
