“…ANDERSSON et al [25] showed high test-retest reliability when measuring walking speed in 49 COPD patients, although the 30-m course may limit generalisation of the findings. EVANS et al [26] demonstrated the validity of self-paced walking and responsiveness to pulmonary rehabilitation in 37 COPD patients. Interestingly, although the test was performed in an enclosed, temperature-controlled 250-m flat corridor, the repeatability was similar to that of 4MGS observed in our study.…”

In community-dwelling older adults, usual gait speed over 4 m (4MGS) consistently predicts greater risk of adverse health outcomes. The aims of the present study were to assess the reliability of the 4MGS and the relationship with established health outcome measures in chronic obstructive pulmonary disease (COPD).Test-retest and interobserver reliability of the 4MGS were measured in 80 and 58 COPD patients, respectively. In 586 COPD patients, the 4MGS, as well as forced expiratory volume in 1 s (FEV1), the incremental shuttle walk (ISW), Medical Research Council (MRC) dyspnoea scale and St George's Respiratory Questionnaire (SGRQ) were measured. Participants were stratified according to ''slow'' (,0.8 m?s -1 ) or ''normal'' 4MGS (o0.8 m?s -1 ). Intra-class correlation coefficients for test-retest and interobserver reliability were 0.97 and 0.99, respectively. There was a significant positive correlation between 4MGS with ISW (r50.78; p,0.001) and a negative correlation with MRC dyspnoea scale and SGRQ (r5 -0.55 and -0.44; p,0.001 for both). COPD patients with slow 4MGS had significantly reduced ISW and higher MRC dyspnoea scale and SGRQ than those with preserved walking speed, despite similar FEV1 % predicted.The 4MGS is reliable in COPD, correlates with exercise capacity, dyspnoea and health-related quality of life, and has potential as a simple assessment tool in COPD. @ERSpublications The 4-metre gait speed test is reliable and valid as a simple assessment tool in chronic obstructive pulmonary disease

“…11 However, due to the cumulative reporting of the data it is not confirmed whether the monitors can detect slow speeds of walking. It is known that patients with COPD sacrifice speed of walking for duration, 12 yet, there is still uncertainty about the ability of the SWM to accurately detect steps and energy expenditure at very slow walking speeds (less than 3.27 km/h). 13,14 The ISWT is used extensively with patients with COPD as an objective measure of exercise capacity with walking speeds increasing over 12 levels each lasting 1 min.…”

“…A SPOW was used to determine the efficacy of walking aids during outdoor use. This test is not designed to replace field exercise tests, but can be used to acquire more patient‐meaningful information . SPOW time is a direct and immediately understandable measure of a commonly stated goal by individuals with COPD entering pulmonary rehabilitation: to walk for longer .…”

“…The efficacy of the walking aids was determined using a SPOW. The SPOW was designed to provide more patient‐meaningful information on walking ability . Because it reports absolute time, the SPOW can be used to evaluate whether and to what extent individuals with COPD are able to walk longer, one of the most common goals described by individuals with COPD entering pulmonary rehabilitation …”

Background and objective: Walking aids, such as rollator or draisine, improve mobility and functional exercise performance in individuals with chronic obstructive pulmonary disease (COPD) during an indoor 6-min walk test. However, this test does not reflect everyday walking, which is the most frequently reported problematic activity of daily life in individuals with COPD.To date, efficacy of walking aids during selfpaced outdoor walking remains unknown. Therefore, we aimed to determine the efficacy of a rollator and draisine on self-paced outdoor walking in individuals with COPD. Methods: Fifteen individuals with COPD (68% men; age: 63 ± 8 years; forced expiratory volume in 1 s: 40 ± 14% predicted) performed three self-paced outdoor walking tests on two consecutive days: test 1 unaided, and tests 2 and 3 with rollator or draisine in random order. Participants had to walk as long as possible at their own pace. The test ended when participants needed to stop, with a maximum duration of 30 min. Results: The use of rollator resulted in the highest walk distance and time (P < 0.05 vs unaided and draisine). Furthermore, individuals with COPD walked significantly further and longer during an unaided test compared with a draisine aided test (P < 0.05). Moreover, use of draisine resulted in a significantly higher walking speed, fewer strides, greater stride length, and higher step and stride variability (P < 0.05 vs unaided and rollator). Conclusion: To conclude, a rollator improves the selfpaced outdoor walk distance and time in individuals with moderate and advanced COPD and a poor functional exercise capacity, whereas the use of a draisine had a detrimental effect compared with unaided walking.
