Background: Multiple System Atrophy (MSA) dysphagia is routinely assessed by the Unified Multiple System Atrophy Rating Scale (UMSARS) part I‐item 2. Objective: To compare the UMSARS part I‐item 2 with an ear/nose/throat (ENT) expert physician assessment. Methods: We retrospectively analyzed the data of MSA patients who underwent an ENT assessment (nasofibroscopic and radioscopic exam) and an annual UMSARS assessment. Deglutition Handicap Index (DHI) and pulmonary/nutrition complications were collected. Results: Seventy‐five MSA patients were included. The ENT assessment revealed more severe dysphagia compared to the UMSARS part I‐item 2 score (P = 0.003). A higher proportion of patients with impaired protective mechanisms showed severe UMSARS‐based dysphagia (P = 0.005). Patients with choking and oral/pharyngeal transit defects and nutritional complications were equally distributed across UMSARS part I‐item 2 scores. Worse UMSARS part I‐item 2 scores had worse DHI scores. Conclusions: The UMSARS‐based assessment of dysphagia does not capture key aspects of pharyngo‐laryngeal dysfunction reflecting swallowing efficiency. [ABSTRACT FROM AUTHOR]
