The relationship between 6 minute walking test and other assessment parameters in patients with modarate-severe chronic obstructive pulmonary disease

Purpose: Our study was conducted to define the relationship between Six-Minute Walking Test which defines exercise capacity and pulmonary function test, arteriel blood gase analysis, dyspnea query, general and health related quality of life questionnaire which are used to evaluate the respiratory patients, and peripheral muscle strength. Material and Methods: 60 moderate to severe chronic obstructive pulmonary disease whose mean age 66,37+ 8.98 were taken for the study. The exercise capacity of the cases was observed by using Six-Minute Walking Test, the lung capacity of the cases was observed by using pulmonary function test and arteriel blood gase analysis. Dyspnea and fatigue observations was carried out with Modified Borg Scale. Health related quality of life was evaluated with Chronic Respiratory Disease Questionnaire. General health related quality of life was evaluated by using Short Form-36 quality of life questionnaire. Hearth rate and peripheral saturation was recorded during the walking test with pulse oximeter. Results: It was determined that walking time, walking distance, and VO2max were corelated with age (r>0,82, p<0,01) and muscle strength (r>0,27, p<0,04), and dyspnea severity (r>0,36, p<0,001). In addition to this, walking time was correlated with FVC% (r=0,29, p=0,03) ve PaO2 (r=0,30, p=0,02). VO2max was correlated with FEV1/FVC (r=0,27, p=0.04). It was determined that all catagories of the Chronic Respiratory Disease Questionnaire without emotional catagories were correlated with walking distance (r>0,24, p<0,04). VO2max was correlated with only Dyspnea catagories (r=0,32, p=0,01), physical function and physical role catagories of Short Form-36 quality of life questionnaire walking time and VO2max. In addition walking distance correlated with physical function, emotional, social, and mental status catagories. There were no correlation between Six-Minute Walking Test data and other assestment parameters. Conclusion: Six-Minute Walking Test results were related with catagories of dyspnea severity, peripheral muscle strength and quality of life questionnaire which observes the physical activity level of the cases more than pulmonary function test and arteriel blood gase analysis. It was determined that explaining the Six-Minute Walking Test results walking distance was more important than VO2max and walking time.
