Abstract
PURPOSE: To validate the de Morton Mobility Index (DEMMI) in older (≥65 years) patients with acute stroke in a hospital setting within the first week after stroke onset.
MATERIALS AND METHODS: In the Danish National Database of Geriatrics, we identified 4,176 patients with acute stroke (≥65 years). Floor and ceiling effects of DEMMI were investigated. Furthermore, convergent validity was investigated by correlations between DEMMI and the Barthel Index using Spearman's rho. Known-groups validity was tested by comparing DEMMI scores for different groups (with/without dementia, depression, comorbidity, and walking aids), and unidimensionality of DEMMI was evaluated by Mokken scale analysis.
RESULTS: A floor effect was identified with 22.1% of the patients scoring 0 on DEMMI on admission. Both convergent and known-groups validity were confirmed for DEMMI. Patients who were bedbound had a lower DEMMI score (median [IQR]: 0 [0;0]) than patients without any walking aid (median [IQR]: 62 [33;74]). Furthermore, Mokken scale analysis identified unidimensionality with overall fit to the model (Loevinger H 0.88 (p < 0.0001)).
CONCLUSION: DEMMI is a valid instrument for use in patients with acute stroke (≥65 years) in a hospital setting within the first week after stroke onset.
