2014
Coordinate mapping is a method of documenting salient features of hyolaryngeal biomechanics in the pharyngeal phase of swallowing. This methodology uses image analysis software to record coordinates of anatomical landmarks. These coordinates are imported into an excel macro and translated into kinematic variables of interest useful in dysphagia research.

Upper GI Series: Barium Swallow
0 Views •
2025
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues. Purpose and Procedure Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Intrinsically Disordered Proteins

2020
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...
FAQs
Sensory feedback helps coordinate the sequence of oral, pharyngeal, and esophageal activity, while precisely timed muscle contractions move material through each phase. When this coordination is disrupted, food, liquid, or saliva may leave residue or fail to move efficiently. Studying these interacting processes helps explain why swallowing problems can affect airway safety, nutrition, communication, and quality of life.
The effects depend on where and how coordinated swallowing is disrupted. Material may remain as residue, trigger coughing or choking, or enter the airway through aspiration. These observable outcomes provide information about the safety and efficiency of swallowing, but they should be interpreted alongside broader clinical assessment rather than treated as evidence of a single cause.
Behavioral research examines eating patterns, avoidance, distress, and responses to food texture alongside the physical features of swallowing. This comparison can help separate behavioral influences from physiological impairment without assuming that every refusal or distress response reflects the same problem. The distinction is important for selecting safer feeding strategies, rehabilitation approaches, and appropriate research interpretations.
Responses to food texture, including avoidance or distress, can reveal how swallowing difficulties affect eating behavior. These observations add context to the physical signs of impaired swallowing and may show that feeding experiences influence participation in meals. Considering both texture-related behavior and physiological impairment supports a more complete understanding of eating, nutrition, and quality of life.
Researchers can observe eating patterns, food avoidance, distress, and responses to different food textures, while relating those behaviors to signs of impaired swallowing. This approach provides behavioral context for clinical assessment and helps identify whether observed difficulties may reflect behavioral influences, physiological impairment, or an interaction between them. The resulting information can guide safer feeding strategies and rehabilitation research.
Information about swallowing disorders is useful when clinicians assess swallowing safety, plan safer feeding strategies, or develop rehabilitation approaches. Behavioral observations can complement this work by showing how distress, avoidance, or texture responses affect eating. In research, the same information helps examine links between swallowing, nutrition, communication, health, and quality of life.
