Self Efficacy, Walking Ability, Gait Speed and Physical Activity in People With Chronic Lung Disease

Determining the Relationships Between Self-efficacy for Walking Ability, Gate Speed and Physical Activity in Patients With Chronic Lung Disease

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.

Inclusion Criteria:

• 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

Exclusion Criteria:

• 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
