TI  - The de Morton mobility index is a feasible and valid mobility assessment tool in 
      hospitalized patients with an acute exacerbation of chronic obstructive pulmonary 
      disease.

AB  - There is no accepted standard for measuring mobility in hospitalized patients 
      with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The 
      objective of this study was to assess convergent, discriminant, and known-group 
      validity and floor/ceiling effects of the de Morton Mobility Index (DEMMI) in 
      hospitalized patients with AECOPD. Individuals with AECOPD (n = 22) admitted to 
      an acute care hospital medical ward were recruited. Data on the DEMMI, gait 
      speed, daytime energy expenditure, step counts, 6-minute walk distance (6MWD), 
      dyspnea, respiratory and heart rates, quality of life, and oxygen supplementation 
      were collected on day 3 of admission. The DEMMI demonstrated convergent validity 
      with the 6MWD and gait velocity measures (Spearman's rho 0.69 and 0.61, 
      respectively; p < 0.003) but not with measures of physical activity or 
      respiratory impairment. Discriminant validity was present, with no correlation 
      between the DEMMI and quality of life and resting heart rate. Known-group 
      validity (gait aids vs. no gait aids) was demonstrated (p = 0.009). There was no 
      floor effect but there was evidence of a possible ceiling effect (14% of 
      participants received a perfect score). The DEMMI is feasible and showed moderate 
      to strong validity with measures of observed physical function in hospitalized 
      patients with AECOPD.
