Self Efficacy, Walking Ability, Gait Speed and Physical Activity in People 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.

|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Determining the Relationships Between Self-efficacy for Walking Ability, Gate Speed and Physical Activity in Patients With Chronic Lung Disease|
- Analyze associations between self-efficacy for walking, gait speed, physical activity level and perceptions of symptoms in patient with chronic lung disease (COPD and Pulmonary Fibrosis) [ Time Frame: Day of enrollment. ] [ Designated as safety issue: No ]Correlation , regression models and mediation analysis (self efficacy and physical activity) will be performed.
- Predictive utility of 4-meter gait speed for estimating physical activity level (PAL) as validated by gold standard activity monitor. [ Time Frame: 1 week ] [ Designated as safety issue: No ]Measure 4-meter gait speed during standardized 6 mintute walk test and compare to armband activity monitor results to determine predictive ability, if any, on PAL in people with chronic lung disease.
