Relationship between Quantified Instrumental Swallowing Examination and Comprehensive Clinical Swallowing Examination

Abstract

The aim of this study was to identify the correlation between the Mann Assessment of Swallowing Ability (MASA) and the Videofluoroscopic Dysphagia Scale (VDS) to investigate the applicability of the MASA as a follow-up test of swallowing function. Criterion validity was assessed for MASA results versus VDS scores of tests administered to 54 patients who had a stroke and dysphagia. A significant correlation was found between the MASA and the VDS (correlation coefficient = -0.509). In analyses of test-re-test reliability and inter-rater reliability of the scoring scale, intraclass correlation coefficients (2, 1) were high (0.98, 0.99). In conclusion, the results of the present study indicate that the MASA holds adequate clinical test-re-test and inter-rater reliabilities and criterion validity for measuring the swallowing abilities of Korean patients who had a stroke and dysphagia. The MASA could contribute to more systematic management of swallowing problems and efficient therapeutic service.
