Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is an observational study investigating the mechanisms of balance problems in people with COPD and how COPD impacts them living their daily lives.

The main objectives of this study are:

* To quantify the relationship between balance and aspects of neuromuscular function in individuals with COPD, and compared to age-matched healthy controls
* To understand the lived experience of people with COPD and their carers

Participants will attend an appointment at the University rehab lab to:

* Complete a balance test
* Fill out some questionnaires on mood, health status and balance and falls
* Complete some walking tests
* Have their body composition measured
* Have the function and strength of their leg nerves and muscles tested Researchers will compare people with COPD and healthy controls (older adults without COPD or other conditions known to impact balance) to see if any of the things measured are impacting the balance of people with COPD more than their peers without COPD.
* For 10 people with COPD only they will be visited at home to observe how they carry out everyday tasks and 5 of those 10 will have a follow up interview.

Researchers will take notes and record interviews and look for similarities and interesting points in the notes and transcripts of the interviews to build a picture of what living with COPD is like.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Chronic obstructive pulmonary disease (COPD) is a progressive condition that affects around 1.2million people in the UK. Breathlessness is the main symptom but people with COPD are also more likely to fall than healthy people of the same age. Falling has emotional consequences, such as feelings of shame, embarrassment and fear of falling in public which leads to avoidance of outdoor activities. Researchers do not know why people with COPD fall more but they have poor balance which may, in part, be due to problems with sensory and muscle responses that would usually maintain balance. Symptoms of breathlessness and pain, plus inactivity, may further impact balance. Physical and social environments may also have a role in falls risk, but this has yet to be investigated. Pulmonary Rehabilitation (PR) which includes stamina and strength exercises, alongside education and emotional support is standard treatment for COPD but it does not include any balance exercises, meaning people with COPD who are at a greater risk of falling do not receive any routine treatment to improve balance. This study aims to investigate the physical, psychological, social and environmental factors impacting on balance in people with COPD by comparing them to older adults without COPD. The study will recruit from local hospital services (people with COPD and their carers without COPD) and within the community (healthy older adults). Balance, muscle function (size, strength and speed of nerve conduction) and physical activity will be measured, and the two groups compared. Researchers will also observe patients in their own homes and do follow up interviews to understand what it is like to live with COPD and the challenges people face. The information from this study will be used in conjunction with stakeholders to co design an intervention to improve balance in people with COPD.
