Data Collection
Data on sociodemographic, fall history, and lung
function were obtained to characterize the sample.
Fall history was assessed with a standardized question
“Have you had any falls in the last 12 months?” Lung
function was assessed with spirometry and the COPD
grade was determined. 10 To assess the effects of the
PR program, activities limitation resulting from breathlessness
and health-related quality of life (HRQOL)
were collected, followed by the assessment of quadriceps
muscle strength, exercise tolerance, and functional
balance. All questionnaires and tests were
administered before and after the PR program.
