Most patients with chronic lung disease underestimate their actual walking ability due to low confidence. To better understand the relationships between lung function, self-efficacy for walking (confidence in ability to walk a defined distance), actual walking ability for the same distance gait speed and physical activity level-PAL- (total energy expenditure/resting metabolic rate).
Quality of life, self efficacy for activity questionnaires, physical activity level measurement, 4-meter gait speed and 6-minute walk distance will be measured.
- Men and women 40 years and older
- Diagnosis of any chronic lung disease as evidenced by pulmonary function testing completed within the prior 12 months
- Able to walk independently and successfully complete the 6-minute walk assessment
- Unable to walk without assistance or complete the 6-minute walk assessment
- Patients unable to comprehend and accurately respond to the study questionnaires either by written or spoken communication
- Patients diagnosed with or treated for a lower respiratory tract infection or COPD exacerbation within the prior 30 days
