Walking aids, such as a rollator or draisine, improve mobility and functional exercise performance in individuals with chronic obstructive pulmonary disease (COPD). This is evident from an indoor six-minute 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, the efficacy of walking aids on outdoor use remains unknown. Therefore, the authors of this study aimed to determine the efficacy of a rollator and draisine on self-paced outdoor walking in individuals with COPD. Fifteen individuals with moderate or advanced COPD and poor functional exercise capacity performed 3 self-paced outdoor walking tests on 2 consecutive days: test 1 unaided; test 2 and 3 with rollator or draisine in random order. Participants were instructed to walk as long as possible, but no longer than 30 min, at their own pace. The authors found that rollator use resulted in the highest walk distance and longest time. In contrast, the use of a draisine had a detrimental effect on walk distance and time spent walking compared to unaided walking, although walking speed was significantly higher.
