Abstract

Background: The six-minute walk test (6MWT) is a good index of physical function and therapeutic response in patients with chronic lung disease. The aim of present study was comparison six-minute walking test with spirometry variables in patients who were candidates for thoracotomy.Methods: In this descriptive-analytic study, 65 patients, who were candidates for thoracotomy, recruited from Al-Zahra Hospital in Isfahan, Iran by simple nonrandom sampling. At the beginning of the study, spirometry then the six-minute walk test was performed in the patients. Also, measurements of oxygen saturation and pulse rate during exercise and distance walked during six minutes were obtained. Three patients were unable to performed six-minute walk test and excluded. Data were collected and analyzed for 65 patients.Finding: The mean age of patients was 44.8 ± 14.2 years. Mean distance walked during six minutes was 427.27 ± 98 meters. There was significant association between mean of distance walked during six minutes and FEV1 dosage (r = 0.5; P = 0.043). There was no significant association between mean of distance walked during six minutes and age (r = -0.15; P = 0.5).Conclusion: The results of this study demonstrated that there is significant association between mean of 6MWT with FEV1 but more studies are needed to assay the relations among 6MWT and spirometry variables.
