Title: Effects of a Brief Pedometer-based Behavioural Intervention for Individuals With COPD During In-patient Pulmonary Rehabilitation on 6-weeks and 6-months Objectively Measured Physical Activity - A Randomised Controlled Trial
Brief Summary: The STAR-study (STay Active after Rehabilitation) investigates in a randomized controlled trial (RCT) the additional effect of a pedometer-based behavior change intervention (BCI) during in-patient pulmonary rehabilitation (PR) on objectively measured physical activity (PA) 6-weeks and 6-months post PR. The BCI uses the behaviour change techniques a) instruction on how, where and when to perform the behavior, b) prompt goal setting for physical activity, c) prompt self-monitoring of behavior and d) feedback on behavior. The primary outcome of PA will be measured using an accelerometer (Actigraph wGT3X) for a time period of seven days, firstly two weeks before rehabilitation begins (T0 = study phase I) as well as six weeks and six months (T3 and T4) after PR. Additionally to predict PA progression after PR, a complex personal diagnostic, including questionnaires as well as functional assessments, is to be carried out at the start (T1 = start of study phase II) and end of PR (T2). This diagnostic is based on the main ideas of the PA-related health competence model (PARC-model) and especially incorporates physical and psychological personal determinants of PA.


Options:
A: Inclusion Criteria:

* Currently in a stable phase of COPD, defined as having had no disease exacerbation within the 4 weeks prior to study entry
* Ambulatory
* Forced expiratory volume in one second (FEV1) less than or equal to 60% of predicted value at screening
* Ratio of FEV1 and forced vital capacity (FEV1/FVC) less than or equal to 65% of predicted value at screening
* Currently receiving long-term oxygen therapy (LTOT)
* Partial pressure of oxygen in arterial blood (PaO2) less than 60 torr

Exclusion Criteria:

* Clinically significant cardiovascular disease (e.g., uncontrolled hypertension, left-sided heart failure, peripheral vascular disease, exertional angina, complex arrhythmias, severe dependent edema, ischemic changes on stress electrocardiogram that would be contraindications for unrestricted ambulation or the 6-minute walk test)
* Orthopedic impairments that would limit ambulation
* Participation in the active phase of pulmonary rehabilitation within the 3 months prior to study entry
* Neurologic impairments (e.g., Parkinson's disease or a stroke) or mental states (e.g., senile dementia) that would limit independent ambulation
* Neoplastic disease that is anticipated to influence survival
* Currently receiving lightweight ambulatory oxygen therapy
* Inability to maintain an oxygen saturation of 92% at rest with 4 liter/minute of continuous oxygen flow and during exercise with an oxygen conserver setting of 6 utilizing a nasal cannula
* Currently a smoker
* Sleep apnea if it is characterized primarily as central sleep apnea syndrome (whether being treated or not) OR if it is known or suspected obstructive sleep apnea that has existed for at least 2 months and has not received stable treatment (stable treatment modes include positive airway pressure therapies or dental orthotic/mandibular positioning devices); individuals with diagnosed obstructive sleep apnea must have a body mass index less than or equal to 30 kg/m2 to be eligible for this study
B: Inclusion Criteria:

* COPD
* FEV1 \< 60% predicted value and FEV1/ FVC \< 70%
* 6-minute walking distance \< 400 m

Exclusion Criteria:

* Patients suffering from cardiovascular, neurological, skeletal muscle, or any other condition that could alter their capacity to perform the exercise test
* Patients taking systemic corticosteroids on a daily basis (patients having received systemic steroids for the treatment of up to two exacerbations in the preceding year and those on inhaled steroids will be allowed)
* Patients with room air PaO2 \< 60 mm Hg will be excluded.
C: Inclusion Criteria:

* Adult \>= 40 years old
* Diagnosis of COPD, emphysema or chronic bronchitis
* Able to walk a minimum of one block
* Sedentary, defined by less than 150 minutes of self-reported physical activity per week
* Have a doctor or primary care provider in the VA who can provide medical clearance
* Competent to give informed consent
* Must be a regular email user (check weekly)
* Have access to a computer with an internet connection, a USB port, and Windows XP or Vista

Exclusion Criteria:

* Diagnosis codes of quadriplegia and paraplegia or pregnancy-related diagnoses or procedures within the previous year will be excluded from potential participant pool
D: Inclusion Criteria:

* Main diagnosis for the Pulmonary Rehabilitation is an International Classification of Diseases-Code J44.- (Other chronic obstructive pulmonary disease) at all 2011 Global Initiative for Chronic Obstructive Lung Disease (GOLD) Classifications A-D and stages 1-4.

Exclusion Criteria:

* Considerably reduced health status (severe concomitant disease, which will affect the results of the outcome parameters, for example, cancer or severe cardiac, neurological or orthopaedic comorbidities)
* Considerable reduction of sight and hearing
* Severe psychiatric condition as secondary diagnosis
* Lack of ability to speak German
