Abstrakt: | BACKGROUND: The inherent stride-to-stride fluctuations during walking are altered in the aging population and could provide insight into gait impairments and falls in patients with COPD. Stride-to-stride fluctuations are quantified two ways: variability of the fluctuations (eg, standard deviation), and movement patterns within the fluctuations. Our objective was to investigate stride-to-stride fluctuations by evaluating the variability and movement patterns of lower limb joints in subjects with COPD compared to subjects without COPD as control subjects. METHODS: In this cross-sectional study, 22 subjects with COPD (age 63 ± 9 y; FEV1 54 ± 19% predicted) and 22 control subjects (age 62 ± 9 y; FEV |
