Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention group 1: Routine care (similiar to control group) with the addition of two fifteen minutes exercise session per day from the second day of admission to day of discharge. The exercise programme will include a walking programme and strengthening exercise. Participants in this group will be required to cover 70% of the distance that they achieve during the 3 minute walk test at initial assessment and perform 8-10 repetitions of each of the strengthening exercises.

Intervention group 2: Routine care in addition of identical exercise programme performed in intervention group 1 from second day of admission to day of discharge. However, participants in this group are only required to cover 40% of their distance achieved during their initial three minute walk test and perform 20-25 repetitions of each of the strengthening exercises.

Outcomes
Primary outcome [1] 5072 0
number of adverse events will be assessed. Events will be classified as an adverse event when the conditions below occur
All adverse events are categorised into adverse physiological incident and adverse physiological changes. Adverse physiological incident refers to an occurrence of one or more adverse physiological changes as a result of one physiotherapy treatment. Examples of adverse physiological incidents include death, acute myocardial infarct, myocarditis, respiratory distress, ventricular arrhythmias, vaso-vagal episodes, collapse and acute musculoskeletal aches and pain. On the other hand, adverse physiological changes refer to change in vital signs during physiotherapy intervention and ten minutes after physiotherapy. The details are as below:

Blood pressure:An alteration in systolic blood pressure > or < 20% of resting value.

Heart rate:>85% of theorized maximum HR calculated by taking 85% of 220- age of patient

Oxygen saturation:Decrease in SpO2 >10% or one which necessitates ceasing treatment (SpO2 <88% on 15lpm or FiO2 of 50%)

Fall that has occurred during the treatment

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will receive usual nursing and medical care on admission into Maroondah Hospital. The nursing unit manager of each ward will refer potential participants to routine ward physiotherapist who is not the principal researcher. The routine ward physiotherapist will ask if potential patients are interested to have more information about the research. The principal researcher will then approach the potential interested patients and will identify if the patient is able to participate in the project.
Upon identification, potential participants will be invited verbally to participate in the project by the principal researcher on the either the 1st or 2nd day of admission. They will be provided with a participant information and consent form. They will also require medical clearance from treating medical unit that participants are suitable to participate in the project and have the capacity to exercise.

Prior to commencement of the recruitment, research investigator (NT) will generate the block sequence. Thirty envelope will be generated using a concealed method. In each envelope, information on group allocation will be included and each participant will be assigned to a number in order of recruitment to the trial. Participants will only be allocated to their group after the assessor has completed baseline assessments. Allocation will be administered by the principal researcher to ensure blinding of the assessor to group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
All participants of this trial will be randomly allocated into one of the three groups (Control(CTRL), 40% exercise programme (EP) and 70% exercise programme (EP)) by applying the block randomisation method (Beller, Gebski, & Keech, 2002).

Summary
Brief summary
The effects of the exercise programme in the pulmonary rehabilitation has been thoroughly evaluated on people who are in their stable stage of COPD and the training has been proven to be very beneficial to this population (Lacasse et al.2003, (Nicki et al., 2006), (Carter & Nicotra, 1996; Mink, 1997). Benefits of exercise training include improved sense of well-being, increase in muscle metabolic capacity, reduction in lactic acid and increase in cross section of muscle fibres (Nicki et al., 2006). However, there are no trial investigating the possibility of implementing the exercise programme for patients who have been admitted for acute exacerbation of COPD.

The primary aims of study is to investigate the safety and feasibility of implementing an exercise programme for patients with acute exacerbation of Chronic Obstructive Pulmonary Disease (COPD) and also aim to establish the optimal intensity of exercise for in-patient exercise programme

An estimated number of 30 participants will be recruited and assessed on the 1st or 2nd day following admission with the intention of commencing intervention from 2nd day of admission up to day of discharge. Out of the three groups, one will be the control group that received standard care and the other two will participate in a twice-daily 15 minutes exercise sessions during the trial duration in addition of standard physiotherapy treatment that the control group will be receiving. The two exercise groups will be exercising at either 40% or 70% maximal output intensity.
