Title: Patterns of Physical Activity Levels in Patients With Bronchiectasis: Cross Sectional Study Using Quantitative Methodology
Brief Summary: The primary aim of this study is to examine the physical activity levels of patients with bronchiectasis.

Subsidiary aims are:

1. To examine whether there is a relationship between the physical activity levels of patients with bronchiectasis and clinical phenotype (disease severity, exercise capacity, quality of life or other symptoms of their disease). The investigators also want to explore the relationship between physical activity levels and readiness to change physical activity behaviour (stages of change, self-efficacy, decisional balance and processes of change).
2. To assess the feasibility and acceptability of the physical activity assessment tools: ActiGraph, ActivPAL, pedometer and the International Physical Activity Questionnaire.

Hypothesis:

Patients with bronchiectasis will have low levels of physical activity, and this is related to their clinical phenotype (disease severity, exercise capacity, quality of life and other symptoms of their disease) and also their readiness to change physical activity behaviour (stages of change, self-efficacy, processes of change and decisional balance).


Options:
A: Inclusion Criteria:

* aged ≥18 years diagnosis of bronchiectasis confirmed by HRCT or CT
* clinically stable (no exacerbation and no significant change in symptoms or medication in the last four weeks)
* sputum bacteriology completed over the past three months

Exclusion Criteria:

* clinically unstable (pulmonary exacerbation or any change in symptoms or medication in the last four weeks)
* current severe haemoptysis
* pregnancy or any other concomitant condition that would prevent participation
B: Inclusion Criteria:

* Patients with moderate and severe bronchiectasis aged 18-75 will be recruited. Severity will be assessed radiologically by HRCT of the chest using the scoring method by Bhalla et al.

Exclusion Criteria:

* cystic fibrosis
* emphysema on HRCT chest and FEV1\<60% predicted
* active allergic bronchopulmonary aspergillosis or tuberculosis
* poorly controlled asthma
* pregnancy or breast feeding
* current smokers
C: Inclusion Criteria:

Bronchiectasis confirmed on High Resolution CT scan Clinical Bronchiectasis confirmed by a respiratory physician. Documented exacerbation within the last year. Independently mobile - i.e. able to undertake pulmonary rehabilitation

Exclusion Criteria:

* Inability to give informed consent to participate
* Age \<18 years
* Primary diagnosis of Chronic Obstructive Pulmonary Disease
* Significant comorbidity that would limit the ability to undertake pulmonary rehabilitation - i.e. Cerebrovascular, cardiovascular or musculoskeletal disease.
* Cystic Fibrosis
* Aortic aneurysm
* Recent myocardial infarction (within previous year)or unstable angina
D: Inclusion Criteria:

* Diagnosis of bronchiectasis (HRCT)
* Stable medical status for last 4 weeks
* History of 2 exacerbations in the last 2 years
* Dysnpoea on exertion (Modified Medical Research Council score \>1)

Exclusion Criteria:

* Concurrent diagnosis of COPD (physician diagnosis and history of 10 pack year smoking)
* Concurrent diagnosis of asthma (history of atopic disease and evidence of bronchodilator reversibility of 12% or 200ml in FEV1 or FVC)
* Concurrent diagnosis of Interstitial lung disease
* Concurrent diagnosis of Cystic Fibrosis
* Medical condition which could place patient at risk during exercise training (angina, neurological or orthopaedic condition)
* Prior completion of pulmonary rehabilitation within the last 12 months
