“…Author found a significant negative correlation between 6MWD and mMRC grading (r -0.559, p 0.000 (<0.001)) which is similar to earlier observation, indicating that with increase in mMRC grading, 6MWD indices may reduce. 14 In present study there was a significant positive correlation between 6MWD and FEV1 (r +0.608, p 0.000 (< 0.001)) as depicted in the scatter diagram ( Figure 1) which is in concurrence with earlier investigations (10,11,14) where r +0.35 (p<0.05), r +0.67, (p<0.001); r 0.43, (p<0.05) respectively. At the same time, a similar study showed positive correlation between 6MWD and FEV1 but does not show any statistical significance(r +0.280 p> 0.05).…”

“…A probable cause for this, could be the much higher prevalence of chronic and active smoking in males and /or much prolonged exposure to smoking. [9][10][11][12] There was a significant negative correlation between 6MWD and age (r=0.384, p=0.000 (<0.001)) observed here, which is similar to earlier findings with positive correlation between 6MWD and age though statistically insignificant (r+0.025, p 0.872). In contrast, findings by Khandelwal et al, showed positive correlation between 6MWD although statistically insignificant (r+0.21 p>0.5).…”

“…Similar significant positive correlations were observed in other studies. 10,14 This observations highlighted a significant positive correlation between 6MWT and height of patients (r +0.261, p 0.09 (<0.05);which is in accordance with earlier observations (10) with (r +0.42, p<0.01), at the same time contradictory to a set of findings by Khandelwal et al, (r -0.06, p>0.05). 14 The height of the subject affects stride length.…”

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.

“…We believed that the best way to estimate the effect of dual-task interference in COPD came from studies focusing on the effect of COPD on the performance of a psychomotor task requiring both cognitive and motor skills (i.e., Trail Making Test). Only one case-control study provided sufficient descriptive statistics to calculate an effect size (Dogra et al 2014). Based on the results, the minimum required sample size was calculated as 64 participants (i.e., 32 in each group) for an effect size of 0.79, a probability level of 0.05, a statistical power level of 90% and assuming a 10% loss to follow up or study exit rate.…”

Recent studies suggest that, compared to healthy individuals, people with chronic obstructive pulmonary disease (pwCOPD) present a reduced capacity to perform cognitive-motor dual-task (CMDT). However, these studies were focused on short-duration CMDT offering limited insight to prolonged CMDT inducing fatigue, which can be encountered in daily life. The present study aimed to explore the effect of adding a cognitive task during repeated muscle contractions on muscle endurance, neuromuscular fatigability and cognitive control in pwCOPD compared to healthy participants Thirteen pwCOPD and thirteen age- and sex-matched healthy participants performed submaximal isometric contractions of the knee extensors until exhaustion in two experimental sessions: (1) without cognitive task and (2) with a concurrent working memory task (i.e., 1-back task). Neuromuscular fatigability (as well as central and peripheral components measured by peripheral magnetic stimulation), cognitive performance and perceived muscle fatigue were assessed throughout the fatiguing tasks. Independently to the experimental condition, pwCOPD exhibited lower muscle endurance compared to healthy participants (p=0.039), mainly explained by earlier peripheral fatigue and faster attainment of higher perceived muscle fatigue (p<0.05). However, neither effect of cognitive task (p=0.223) nor interaction effect (group × condition ; p=0.136) was revealed for muscle endurance. Interestingly, cognitive control was significantly reduced only in pwCOPD at the end of CMDT (p<0.015), suggesting greater difficulty for patients with dual-tasking under fatigue. These findings provide novel insights into how and why fatigue develops in COPD in dual-task context, offering a rationale for including such tasks in rehabilitation programs.
