Title: The Role of Home-monitoring in the Adherence of Patients With Chronic Obstructive Pulmonary Disease to Long-term Rehabilitation
Brief Summary: The aim of this randomized controlled trial is to investigate the effects of adding PA monitoring and regular feedback of a pedometer (step counter) to an outpatient pulmonary rehabilitation (PR) program on daily PA levels and health status of patients with COPD.

Patients will be randomized to either receive a PR program with PA monitoring and regular feedback of a pedometer (experimental group \[EG\]) or a PR program alone (control group \[CG\]). During the PR program, patients in the EG will receive a pedometer to self-monitor their PA and individualized step-count goals. They will continue to use the pedometers and receive individualized goals for 3 months after the program.

It is expected that, by receiving individualized goals and a simple pedometer to self-monitor their PA during and after a PR program, patients with COPD will become more active and adhere to long-term rehabilitation, thus reducing the overall impact of COPD.

* clinical stability for 1 month prior to the study (no hospital admissions or exacerbations)
* able to provide their own informed consent

Exclusion Criteria:

* inability to understand and co-operate
* presence of severe psychiatric conditions
* presence of severe neurologic/ musculoskeletal conditions and/or unstable cardiovascular disease
* participation in regular strenuous exercise (e.g., greater than 10 hours per week of running, swimming, weightlifting or any other similar physical activity) prior to the study
C: Inclusion Criteria:

1. COPD defined as FEV1 (Forced expiratory volume in 1 second)/FVC (Forced vital capacity) \<0.70 or chest CT evidence of emphysema
2. Age \> 40 years
3. Any severity of COPD as defined by GOLD (Global Obstructive Lung Disease) stages 1, 2,3, or 4
4. Completion of standard pulmonary rehabilitation of at least 8 weeks duration within 24 weeks prior to study entry\* \*Defined as attending 65% of the program's sessions with a minimum of 10 sessions

Exclusion Criteria:

1. COPD exacerbation requiring steroids, antibiotics, ED visit or hospitalization within the past 2 weeks unless physician deems subject at baseline
2. Hypoxemia on walk test (O2 sat \< 85% on oxygen)
3. Inability to ambulate due to vascular or other neuromuscular conditions that would preclude a walk test
4. Clinical signs of unstable cardiovascular disease (ie. chest pain on walk test)
5. Severe cognitive dysfunction (documented Mini-Mental Status Exam ≤ 24)
6. Non-English speaking
7. Current regular practice of tai chi
8. Current diagnosis of lung cancer or treated for lung cancer within the past 5 years
9. Unstable/untreated mental health issue that precludes informed consent or otherwise affects ability to participate in the intervention
D: Inclusion Criteria:

To be eligible for inclusion in this study Patients fulfil all of the following criteria:

1. Written informed consent obtained before any assessment is performed.
2. Male and female patients ≥ 40 years of age
3. Diagnosis of COPD \[post-bronchodilator forced expiratory volume at one second (FEV1) \<80% predicted and FEV1/ forced vital capacity (FVC) \<75% without significant post-bronchodilator reversibility (\<10% FEV1 % predicted normal)\]
4. Optimal medical treatment according to GOLD without regular use of systemic corticosteroids
5. Current or ex-smokers with a smoking history equivalent to at least 10 pack years (1 pack year = 20 cigarettes smoked per day for 1 year)
6. Absence of other significant diseases that could contribute to exercise limitation
7. At least 2 COPD exacerbations the year before the time entry

Exclusion Criteria:

Patients fulfilling any of the following criteria are not eligible for inclusion in this study. No additional exclusions are applied by the investigator, in order to ensure that the study population will be representative of all eligible patients.

1. Orthopedic, neurological or other complaints that significantly impair normal biomechanical movement patterns, as judged by the investigator. Specifically if the patients' condition/ co-morbidities are such that physical activity cannot be increased.
2. Respiratory diseases other than COPD (e.g. asthma)
3. Cognitive reading impairment and/or difficulties to manage electronic devices precluding interaction with the tablet, as judged by the investigator
4. Patients not on optimal pharmacotherapy
5. No COPD exacerbations the year before the time entry
