The aim of this study is to evaluate the effects of a three-week inpatient pulmonary rehabilitation (PR) program on the walking speed in patients with chronic obstructive (COPD) or interstitial lung disease (ILD).
At most german traffic light crossings, a walking speed of 1,2m/sec is required to cross the road in time. Patients who are unable to cross the road at this speed, expose themselves to an increased level of stress and possibly the risk of accidents. Thus, they are discouraged from participating in an active social life. An UK study (Nolan et al., Thorax 2018) showed that only 10.7% of the 926 patients with moderate COPD attained a walking speed of 1.2m/sec. As PR plays a key role in the management of chronic lung diseases in order to improve patients´ exercise capacity, the aim of this study was to evaluate the PR effects on the Walking Speed in patients with COPD or ILD. The investigators hypothesize that PR improves the ability to cross the road in the appropriate time.

Change in anxiety and Depression symptoms
Anxiety/Depression measured by Hospital Anxiety and Depression Scale (HADS) - a screening questionnaire including seven questions each about Depression and Anxiety; each part ranging from 0 to 21; higher scores indicate higher presence of the respective state

Time frame: Day 1 and Day 21
Change of frailty (FFP)
measured by Fried Frailty Phenotype (FFP), including five constructs (weight loss, exhaustion, physical activity, gait speed and weakness); range 0-5, higher scores reflect increased Frailty: A score of 0 is considered as "robust", a score of 1-2 is considered as "pre-frail", a score lower than 2 reflects "Frailty"
Time frame: Day 1 and Day 21
Change in Quality of life: Chronic Respiratory Disease Questionnaire (CRQ)
assessed by the Chronic Respiratory Disease Questionnaire (CRQ)- a 20-item self-report questionnaire; score 1-7; higher scores indicate a better health-related quality of life
Time frame: Day 1 and Day 21
Change in illness perception
assessed by the Illness perception Questionnaire, revised (IPQ-R) - 18 items, score 1-5; higher scores indicate a worse illness perception, except of item 7,9,10,11,12.
Time frame: Day 1 and Day 21
Change in COPD-related fears on disease-specific disability
assessed by the German "COPD Angst Fragebogen" (CAF) - a 20-item self-report questionnaire, rated on a Lickert-scale (score 0-4); highest maximum score: 80 points; higher scores indicate higher anxiety levels.
Time frame: Day 1 and Day 21
