Which measure evaluates swallowing impairment and severity based on instrumental imaging and is designed for systematic scoring of the swallowing physiology?

• A. FOIS
• B. PAS
• C. MBSImP
• D. DOSS

Answer: (C)

Focusing on a structured, imaging-based assessment of the swallow's physiology is what this measure does best. The Modified Barium Swallow Impairment Profile is designed to be used with videofluoroscopic swallow studies to rate multiple components of the swallow process—such as lip closure, tongue movement, airway protection, bolus flow, and esophageal clearance—across a standardized impairment scale. By scoring each physiologic component, it provides both a total impairment score and detailed component-level information, giving a clear picture of how severe the dysfunction is and where it occurs. This systematic approach makes it especially useful for documenting impairment, tracking change over time, and comparing across patients or studies.

In contrast, functional scales like the Functional Oral Intake Scale focus on how much and what type of oral intake the patient can manage, not on the underlying imaging-based physiology. The Penetration-Aspiration Scale centers on whether material enters the airway and how severe that event is, rather than providing a comprehensive physiologic profile of the swallow. The Dysphagia scales that gauge general safety or efficiency at a more global level don’t offer the same detailed, instrument-based breakdown of swallowing physiology that the MBSImP provides.
