Abstract: BACKGROUND:The Munich Swallowing Score (MUCSS) is a clinician rated scale for the assessment of the functional level of swallowing saliva/secretions, food and liquids. The MUCSS consists of two eight-point subscales, MUCSS-Saliva and MUCSS-Nutrition. In a previous article, content validity and interrater reliability were described. OBJECTIVE:The aim of the present study was to investigate criterion validity and sensitivity to change of the MUCSS. METHODS:The research was conducted at a tertiary care academic hospital. Data were collected retrospectively in a cohort of 100 acute and subacute neurologic patients. Criterion validity was judged by comparison to the Gugging Swallowing Screen (GUSS), the Barthel Index (BI), Early Rehabilitation Barthel Index (ERI), Extended Barthel Index (EBI) and also by comparison to three physiological scales drawn from FEES videos: The Penetration - Aspiration Scale (PAS), the Yale Pharyngeal Residue Severity Rating Scale (YPR) and the Murray Secretion Scale (MSS). Changes in oral intake and saliva swallowing were followed up for three months. RESULTS:Between MUCSS and scores directly reflecting dysphagic symptoms (GUSS, PAS, YPR, MSS, ERI), strong to moderate correlations were found, weaker but statistically significant associations were seen with global measures of disability (BI isolated, EBI-subscale cognitive functions). MUCSS was sensitive to positive change of saliva swallowing and oral intake during the recovery period. CONCLUSIONS:These preliminary data suggest that the MUCCS is a valid scale and may be appropriate for documenting clinical change in swallowing abilities of patients with neurogenic dysphagia.
