Effects of an Exercise Intervention in Frail Older Patients with Chronic Obstructive Pulmonary Disease Hospitalized due to an Exacerbation: A Randomized Controlled Trial

ABSTRACTThe objective of this study was to determine whether an exercise intervention using a pedal exerciser is able to reduce disability in frail older patients with chronic obstructive pulmonary disease (COPD) during hospitalization due to an acute exacerbation.This study was a randomized, single-blind clinical trial. Fifty-eight frail older patients admitted to hospital due to an acute exacerbation of COPD (AECOPD) were included in this study. All patients received standard medical and pharmacological care. Patients assigned to the intervention group also received an exercise intervention. The main outcome measures were balance, muscle strength, and exercise capacity.Significant between-group differences were found in muscle strength (p = 0.028) and balance (p = 0.013) after the intervention. All the variables improved significantly (p < 0.05) in the exercise intervention group. In the intervention group, the mean difference in muscle strength between baseline and discharge was 10.47 N. Balance also i...
