Chronic Obstructive Pulmonary Disease (COPD) is a respiratory disease starting point characterized by multiple systemic effects as cognitive dysfunction. This one seems to have an impact in activity daily living, considered mainly as a cognitive-motor dual task situations. Yet to date, no study has specifically focused in the cognitive-motor performance in patients with COPD or on the effects during a rehabilitation program. The main objective of this work was to evaluate the impact of cognitive dysfunction in COPD, comparing performance between COPD patients and healthy subjects in a single and dual task cognitive-motor situation. The secondary objective was to assess the impact of a rehabilitation program on these performances.
