This research project incorporates a series of studies to investigate the relationship between physical performance (e.g. tests of strength, balance and walking distance) and physical activity (activity measured in day to day life) in people with COPD and other chronic lung diseases.
The research project incorporates the following components: Study 1) A prospective, observational study, to assess the relationship between a comprehensive set of measures of walking ability, strength and balance, and daily physical activity in people with chronic lung disease. Patients will attend a single assessment session to evaluate physical capacity. They will also wear a physical activity monitor for a week following completing these tests to assess physical activity and aspects of physical performance. Participants will also be invited to return two months later to provide evidence about the repeatability of measurements. Study 2) A parallel study comparing assessment of performance during six-minute walk tests by an observer to a semi-automated assessment using an activity monitor worn by the patient. This will involve a single visit and be carried out during walking tests carried out as part of routine clinical care. Study 3) A qualitative study to investigate experiences and perceptions of participants of dance groups for people with chronic lung disease, as a novel form of physical activity. This will be used to inform the design of subsequent trials of dance interventions for chronic lung disease.

RECRUITINGFree-living gait stability as assessed by activity monitor
The free-living gait stability parameters derived from the fixed body sensor worn during activity monitoring at home.
Time frame: 7 days.
Physical activity assessed by step count using activity monitor
Physical activity assessed using step count (number of steps), as assessed using the activity monitor at home (McRoberts MoveMonitor).
Time frame: 7 days.
Clinical balance assessment
Assessed using the miniBESTest in clinical setting.
Time frame: Assessed during single clinical assessement at baseline.
Physical performance assessment
Assessed using the Short Physical Performance Battery (SPPB) in clinical setting.
Time frame: Assessed during single clinical assessment at baseline.
Balance confidence
Assessed using the Activities-specific Balance Confidence (ABC) scale. This is a self completed measure of balance confidence during common activities of daily living. It includes 16 questions which participant give a percentage confidence response with 0% being not confident at all and 100% being completely confident. There is also a total score out from 0% (least confident) to 100% (most confident) for overall balance confidence, which average created by combining the scores given for the separate questions.
Time frame: Assessed during a single clinical assessment at baseline.
Walking distance in metres
Assessed using the six-minute walk test in clinical setting.
Time frame: Assessed during a single clinical assessment at baseline.

Patient experience as assessed by semi-structured interviews
The patients experience assessed by semi-structured interviews in focus group.
Time frame: 1 hour.
Physical Activity: Movement intensity (in average body acceleration (g) during activity)
Movement intensity measurement is assessed using the fixed body sensor worn during activity monitoring at home.
Time frame: 7 days.
Physical activity: types of activity (time in minutes spent standing, walking, lying, sitting, cycling, running) assessed with activity monitor.
Types of activity (time measured in minutes spent standing, walking, lying, sitting, cycling, running) is assessed using the fixed body sensor worn during activity monitoring at home.
Time frame: 7 days.
Timed Up and Go (TUG)
Time in seconds to complete the standard TUG protocol
Time frame: Assessed during a single clinical assessment at baseline.
Functional reach test
Assessed using standard functional reach protocol
Time frame: Assessed during a single clinical assessment at baseline.
