Metric Properties of de Morton Mobility Index (DEMMIURIS)

Metric Properties of de Morton Mobility Index in Rehabilitation Patients With Musculoskeletal Impairments

Metric properties (convergent validity, predict validity, known-groups validity, responsiveness, floor and ceiling effects, minimal clinically important difference) of the de Morton Mobility Index (DEMMI) in patients with musculoskeletal impairments undergoing impatient rehabilitation will be investigated.

Study Overview

• Status: Completed
• Conditions: Musculoskeletal Diseases

Detailed Description

Convergent validity of DEMMI will be assessed in terms of correlations with the other outcome measures. Known-groups validity will be demonstrated by differences in DEMMI scores between patients who were not able to walk and those who were able to walk with or without walking aid. Predictive validity of DEMMI at admission for functional independence at discharge from rehabilitation will be estimated. The minimal clinically important difference of DEMMI, responsiveness and floor or ceiling effects will also be estimated.
