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.
