Title: Tai Chi After Pulmonary Rehabilitation in Patients With COPD: A Randomized Trial
Brief Summary: The main purpose of this study is to determine the feasibility and effects of a 6-month tai chi exercise program as compared to a 6-month group walking program and standard care for patients with COPD that have recently completed a pulmonary rehabilitation program.


Options:
A: Inclusion Criteria:

* People diagnosed with COPD or diabetes type 2 who are predominantly treated in primary care and who benefit from more physical activity, will be included. -This means patients who do not comply with the Dutch Norm for Healthy Exercise (30 minutes activity per day of a moderate intensity during five days a week)
* Their age should be between 40-70 years to ensure homogeneity in the groups
* Additional inclusion criteria for the diabetes group are a recent (no longer than a year ago) HbA1c concentration of more than 7% / more than 53 mmol/mol and a body mass index of more than 25kg/m2

For the COPD group the following additional inclusion criteria apply:

-A clinical diagnosis of COPD according to the GOLD-criteria stage 1, 2 and 3 (post bronchodilator FEV1/IVC \<= 70% and FEV1 between 30 and 80% of the predicted value); at least six weeks respiratory stable and on a stable drug regimen

Exclusion Criteria:

-Patients older than 70 years are not included because of a bigger risk for co-morbidity and a higher chance of mobility problems (balance)
B: 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
C: 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
D: Inclusion Criteria:

* Adult male and female patients aged ≥ 40 with stable moderate to severe COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines).
* Post-salbutamol Forced Expiratory Volume in one second(FEV1) \< 80% and ≥ 30% of predicted normal value and Post-salbutamol FEV1/Forced Vital Capacity (FVC) \< 70%.
* Current or ex-smokers of ≥ 10 pack-years
* Functional residual capacity (FRC) measured by body plethysmography at Screening Visit ≥ 120% of predicted value

Exclusion Criteria:

* History or current diagnosis of asthma
* Signs of an exacerbation within 6 weeks ( or 3 months if results in hospitalisation) prior to the screening visit or during the run-in period.
* Clinically significant respiratory and/or cardiovascular conditions or laboratory abnormalities.
* Conditions where the use of anticholinergic drugs is contraindicated, such as known symptomatic prostatic hypertrophy, bladder neck obstruction or narrow-angle glaucoma.
* Patients with an oxygen saturation \< 85% during cycle exercise on room air at Screening Visit, Run- in Visit and Visit 1.
* Contra-indications of cardiopulmonary exercise testing.
* Patient who in the investigator's opinion will need to start a pulmonary rehabilitation program during the study and/or patients who have just started/finished pulmonary rehabilitation at least 3 months prior to the Screening Visit.
