Primary Outcome Measures

Name	Time	Method
Convegent Validity: Hypothesis testing with respect to correlations between the index test (DEMMI) and other validated measures of mobility (Hierarchical Assessment of Balance and Mobility, Functional Ambulation Categories, Performance Oriented Mobility Assessment, gait speed, Timed Up And Go Test, 2 Minute Walk Test, Short Physical Performance Battery, Barthel Index-Mobility).

Secondary Outcome Measures

Name	Time	Method
1) Test-retest reliability (level of agreement betwen 2 test results = Intra Class Coefficient [ICC]).<br><br>2) Feasibility (time to administer the DEMMI, number of adverse events).<br><br>3) Responsiveness-to-change: Hypothesis testing based on correlations between changes in the index test (DEMMI) and the reference tests. Area under the curve (AUC) with respect to a change in mobility levels (yes/no based on the global rating of change).<br><br>4) Interpretability: floor- and ceiling-effects will be reported descriptively.<br><br>5) Unidimensionality: Rasch analysis.
