Plain English Summary
Background and study aims
There is a lot of research that tells us that people who have been in the Intensive Care Unit (ICU) in hospital can often (but not always) experience ongoing problems such as loss of general fitness, balance and strength, or experience higher levels of anxiety and depression. Our study aims to investigate whether a six-week exercise programme can improve any of these possible difficulties experienced by patients who have been discharged home from hospital, after having been in the ICU for more than 48 hours.
Who can participate?
Patients aged 18 or over who have been in the ICU for longer than 48 hours.
What does the study involve?
The study involves attending the physiotherapy department in Morriston Hospital for about 30 minutes, where the patient will carry out three simple fitness tests and complete a short questionnaire. The fitness tests include the Six Minute Walk Test which involves walking for six minutes if the patient is able, a series of simple balance exercises and a test where the patient squeezes their hands into a fist as tight as possible to measure grip strength. Following these tests, the patients will be randomly allocated to either the control group or the exercise group. The control group will be given a general advice sheet on exercise and will then re-attend the physiotherapy department seven weeks later to complete the same series of tests. The exercise group will be asked to attend the physiotherapy gym in Morriston Hospital twice a week for six weeks where they will carry out an exercise programme with a physiotherapist either on their own or with one other patient. The programme will include exercises such as using the treadmill, rowing machine, static bike or stepper and simple strengthening and balance exercises. These sessions will last between 40 minutes and one hour. At the end of the six weeks, the patient will complete the same series of tests that were completed at the start of the programme. Both groups of patients will be asked to complete the tests at 6 months and one year after the study in order to assess any longer lasting benefits of the programme.
What are the possible benefits and risks of participating?
There are no risks associated with this study. The patient may feel slight muscle soreness
the day after they have exercised but they will be warmed up and cooled down properly in
order to minimise this risk.
Where is the study run from?
Morriston Hospital (UK).
When is the study starting and how long is it expected to run for?
November 2011 to October 2013.
Who is funding the study?
This study is receiving no funding from any external source. The ICU physiotherapy team are completing the study as part of their normal daily work.

A randomised controlled trial examining the effect of a six week supervised exercise programme on patient fitness and hospital related anxiety and depression following an intensive care length of stay of greater than 48 hours
1. What is the impact of a six week supervised exercise programme on cardiopulmonary fitness in patients who have been discharged home from hospital following an intensive care unit (ICU) length of stay of greater than 48 hours?
2. What is the impact of a six week supervised exercise programme on balance, muscle strength, anxiety and depression levels in patients who have been discharged home from hospital following an ICU length of stay of greater than 48 hours?
3. What is the impact of a six week supervised exercise programme on mortality, return to work and primary and secondary care utilisation at six month and one year follow up?
