An investigation of the measurement properties of the de Morton Mobility Index for measuring mobility capacity in hospital patients with Parkinson's disease.

ABSTRACT:

Objective

To examine the measurement properties of the de Morton Mobility Index (DEMMI), a performance-based clinical outcome assessment of mobility capacity, in hospital patients with Parkinson's disease.

Design

Cross-sectional study.

Participants

Hospital patients with Parkinson's disease.

Main outcome measure(s)

Structural validity and unidimensionality (Rasch analysis), construct validity, internal consistency reliability, and inter-rater reliability of the de Morton Mobility Index (scale range: 0-100 points) were established. The minimal detectable change, the 95% limits of agreement and possible floor and ceiling effects were calculated to indicate interpretability.

Results

We analysed validity (n = 100; mean age: 70 years; 71% male) and rel
