title: Walking Pattern in COPD Patients.
abstract: OBJECTIVE
  To compare the activity and walking pattern of individuals with chronic obstructive pulmonary disease (COPD) and control subjects during a 24-hour period.
  
  
  METHODS
  Cross-sectional study in home and community.
  
  
  METHODS
  The average walking velocity, time spent in sitting, standing, and lying, and numbers of steps per 24 hours were measured in nine individuals with COPD and eight healthy control subjects.
  
  
  RESULTS
  The average walking velocity in individuals with COPD was equivalent to that of the control subjects. Individuals with COPD walked significantly less than the control subjects. The total time spent sitting, standing, and walking was similar in the two groups.
  
  
  CONCLUSIONS
  The results suggested that the walking velocity selected by individuals with COPD serves to minimize energy cost per distance.
  
  
  CONCLUSIONS
  The study findings emphasize the need to maintain walking velocity in any exercise prescription for individuals with COPD.
