The mobility of people living with COPD is affected negatively by the disease symptoms. However, limited data are available on the life-space mobility in people with COPD on long-term oxygen therapy (LTOT). This study aimed to explore the life-space mobility in subjects with COPD on LTOT and verify whether life-space mobility is associated with comorbidities and symptoms, activity in daily life, exercise capacity performance, and quality of life.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>\n                      This cross-sectional study enrolled 61 subjects with COPD on LTOT (73.0 \u00b1 8.8 y, FEV\n                      <jats:sub>1<\/jats:sub>\n                      41.7 \u00b1 16.0% predicted, on LTOT for 2.8 \u00b1 3.3 y).
