“…The six minute walk test (6MW) was used to measure physical performance. Two tests were performed approximately 30 minutes apart on the same day in a hospital corridor (Guyatt et al, 1985). If the two walk distances did not agree within 10%, a third walk was performed.…”

“…For example, the 6-minute walk (8) is a popular objective surrogate because of its simplicity, correlation with dyspnea, functional status (9) and quality of life (10), and its responsiveness to a wide variety of interventions (11). However, even laboratory-based exercise tests are only indirect surrogates of "freeliving" functional performance and only capture limited aspects of the disease's overall impact (5).…”

There is increasing interest in the objective measurement of physical activity in chronic obstructive pulmonary disease (COPD) patients due to the close relationship between physical activity level, health, disability and mortality. We aimed to (a) determine the validity and reproducibility of an activity monitor that integrates accelerometry with multiple physiologic sensors in the determination of energy expenditure in COPD subjects and (b) to document the independent contribution of the additional physiologic sensors to accelerometry measures in improving true energy expenditure determination. Eight subjects (4 male, FEV 1 56.4 ± 14.1%, RV 145.0 ± 75.7%) performed 2 separate 6-minute walk and 2 incremental shuttle walk exercise tests. Energy expenditure was calculated during each exercise test using the physiologic activity monitor and compared to a validated exhaled breath metabolic system. Test-retest reproducibility of physiologic activity monitor during the walking tests was comparable to an exhaled breath metabolic system. Physiologic sensor data significantly improved the explained variance in energy expenditure determination (r 2 = 0.88) compared to accelerometry data alone (r 2 = 0.68). This physiologic activity monitor provides a valid and reproducible estimate of energy expenditure during slow to moderate paced walking in a laboratory setting and represents an objective method to assess activity in COPD subjects.

“…The distances covered during the 6MWT, which appropriately reflect the physical capacity to perform daily tasks, were registered for analyses [22][23][24] . The test was carried out, following the procedures and recommendations of the American Thoracic Society 25 , which were adapted to the Brazilian Portuguese language 26 .…”

| Background: The assessment of strength and its relationships with functional capacity could contribute to more specific and effective disability management of stroke survivors. Objective: To compare and investigate associations between measures of strength and functional capacity of 98 chronic stroke survivors, stratified into three groups, according to their physical activity levels. Method: The physical activity levels were classified as impaired, moderately active, and active, based on their Human Activity Profile (HAP) scores. Strength was assessed by the maximal inspiratory (MIP) and expiratory (MEP) pressures and by the residual deficits (RDs) of work of the lower limb and trunk muscles, whereas functional capacity was evaluated by the distance covered during the six-minute walking test (6MWT). Results: One-way analyses of variance revealed significant differences between the groups, except between the active and moderately active groups regarding the RDS of the hip and knee flexors/extensors and ankle dorsiflexors (2.91
