Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients are randomised to participate in aerobic exercise three times a week for 12 weeks or usual care. The exercise classes include stations of treadmill training, stationary cycling, arm and/or leg ergometry and weight bearing exercise such as steps and overground walking and last for 1 hour. Blinded assessment of outcome is performed at baseline, 3 and 6 months.

Rehabilitation
Comparator / control treatment
Usual care provided by patients' general practitioner and allied health professionals, excluding supervised aerobic exercise programmes for 12 weeks, the same duration as the exercise group.

Can healthy volunteers participate?
No
Key exclusion criteria
Patients who are unable to participate in an exercise programme due to medical conditions such as heart failure, unstable angina, dementia and receptive aphasia. Patients on beta-blockers.

Patients who have epilepsy, metallic implants in the skull or cardiac pacemakers will be excluded from the transcranial magnetic stimulation.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was performed by a person independent to the study and concealed in sealed opaque envelopes. After baseline testing, the research assistant not blinded to group allocation contacted this researcher and informed the participant of group allocation. The outcome assessor remained blinded to allocation until after the statistical analyses were completed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The random sequence was generated using software by researchers not involved with participants or data collection. There was no stratification. This was decided before the first participant was recruited

Summary
Brief summary
Aerobic exercise can improve cardiovascular fitness, mobility and physical function following stroke but it is not known whether it has an effect on cognitive and neurological function. We intend to compare a 12 week exercise program with usual care to document changes in impairment, activity and participation, as well as performing a cost-effectiveness study.
