Minute Walk

Background: Six‑Minute Walk Test (6MWT) is a simple, objective, reproducible test which correlated well with different spirometric indices, and thus able to predict severity of Chronic Obstructive Pulmonary Disease (COPD) and can replace spirometry in resource poor set‑up. Here, author evaluated the correlation of 6 minute walk distance (6MWD) with spirometric indices in COPD patients and the potential of 6MWT as an alternative to the assessment of severity of COPD.Methods: This cross-sectional observational study included a total of 80 COPD patients, diagnosed by GOLD criteria (Post bronchodilator FEV1/ FVC ratio <0.7). Modified Medical Research Council (mMRC) grading was used (age, weight, height, body mass index- BMI and breathlessness) and all the patients underwent spirometric measurement of FEV1, FVC and FEV1/ FVC ratio and tests were repeated after bronchodilation using 200-400 μg of salbutamol. 6MWT was performed following American Thoracic Society (ATS) protocol of 6MWT and distance was measured in meters.Results: Author found significant negative correlation of 6MWT with age (r=-0.384, p=0.00) and mMRC grading of dyspnea (r=-0.559, p=0.00) and significant positive correlation with height (r=0.267, p=0.019) and weight (r=0.293, p=0.008). Significant positive correlation of 6MWD was noted with post bronchodilator FEV1(r=0.608, p=0.00), FEV1% (r=0.429, p=0.00), FVC (r=0.514 p=0.00), FVC% (r=0.313 p=0.005), FEV1/FVC % (r=0.336, p=0.001). Positive correlation was also observed between 6MWT and BMI but statistically insignificant (r=0.177, p=0.116). There was significant negative correlation between 6MWT and GOLD staging (r=-0.536, p=0.00).Conclusions: This finding concludes that 6MWT can be used for the assessment of severity of disease in COPD patients in places where spirometry is not available.

Minute Walk

Background: Six minute walk test (6MWT) is a sub-maximal exercise test, used as a clinical indicator of the functional capacity, in patients with cardiopulmonary diseases. It is simple, objective and reproducible test. The present study was designed to assess correlation of six minute walk test with spirometry parameters, in patients with chronic obstructive pulmonary disease.Methods: In this cross sectional study, fifty patients diagnosed with chronic obstructive pulmonary disease (GOLD criteria) coming to tertiary center were recruited according to inclusion and exclusion criteria. All patients underwent spirometric measurement. Spirometric indices including FEV1, FVC, FEV1/FVC and MVV were tested using computerized spirometer. 6MWT was performed following American Thoracic Society (ATS) guidelines. Percent (%) predicted 6MWD was calculated. Correlation between spirometry and 6MWT was assessed.Results: It was found that correlation between 6MWT and spirometry is statistically significant. There is significant strong positive correlation between percent predicted 6MWD and FEV1 (r=0.850 and p= <0.001), whereas there is significant moderate correlation between percent predicted 6MWD and FVC (r=0.554 and p= <0.001), FEV1/FVC (r=0.509 and p= <0.001) and MVV (r=0.615 and p= <0.001).Conclusions: In chronic obstructive pulmonary disease, percent predicted 6mwd significantly correlated with the spirometry parameters (FEV1, FVC, FEV1/FVC, and MVV). 6MWD decreases as there is decline in the pulmonary function. 6MWT can be a useful replacement of spirometry in assessment of severity of COPD.

Background: The six-minute walk test (6MWT) is widely used because it is both simple and reliable as a measure of exercise capacity. Individuals with chronic obstructive pulmonary disease (COPD) usually show a limited capacity to perform exercise. Methods: Our study is a prospective, randomized controlled trial which uses the 6MWT in one hundred consecutive in and out- patients with moderate to severe COPD to assess the benefit of a simple positive expiratory pressure (PEP) device. PEP device consisted of a PEP valve 5 cmH2O connected to 1-meter tube and a mouthpiece. All the enrolled patients performed a 6MWT before randomization. The following day PEP group patients performed the 6MWT using PEP device. Control group patients performed the 6MWT without this device. The primary outcome was the difference in distance (meters) walked. Results: Functional capacity assessed by the distance covered during 6MWT improved in the PEP group more than in the control group. The difference was statistically significant (p < 0.001).Oxygen saturation improved to a statistically significant level during 6MWT (p < 0.01). Heart rate was also reduced (p < 0.03). Conclusions: There are few studies demonstrating that PEP devices enhance exercise capacity in COPD patients. Our results has been obtained using only a low positive expiratory pressure (5 cmH2O). In our opinion the strength of this study is the simplicity and the lower cost when compared to other devices and approaches. The study was registered as Chi CTR-ORC-12002173 at www.chictr.org.
