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

This study has been completed.

Last verified: March 2013

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.

Chronic Lung Disease Self-efficacy

Study Type: Observational

Further study details as provided by Roberto P. Benzo, Mayo Clinic:

Primary Outcome Measures:
  • 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. ]
    Correlation , regression models and mediation analysis (self efficacy and physical activity) will be performed.

Secondary Outcome Measures:
  • Predictive utility of 4-meter gait speed for estimating physical activity level (PAL) as validated by gold standard activity monitor. [ Time Frame: 1 week ]
    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.
