Brief Summary

Stroke is a leading cause of adult disability in the UK. There are few treatment options that improve long-term disability outcomes after stroke. Animal studies indicate that aerobic exercise training can improve brain repair and reduce disability after stroke. However, in clinical practice it is difficult for stroke survivors to undertake aerobic exercise due to lower-limb disability and a lack of accessible exercise equipment. This study will assess the feasibility of implementing a 5-day aerobic exercise training intervention, beginning in the acute phase of stroke (1-7 days post-stroke), using a power-assisted exercise bike. Feasibility outcome measures: recruitment rate (30 participants recruited within 18 months), completeness of data (\>80% of planned measurements recorded) and the safety (\<10 adverse events related to the intervention) and acceptability (\>3/5 comfort scale) of the intervention. We will also investigate the acute effects of aerobic exercise on cerebral blood flow velocity using transcranial Doppler ultrasound, and brain-derived neurotrophic factor (serum and plasma).

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult (age \>18 years) patients diagnosed with acute ischaemic stroke 1-7 days previously.
  • Medically stable, assessed by a stroke physician.
  • Sufficient English language comprehension and cognitive ability to understand the study protocol, follow instructions, complete questionnaires and give informed consent.

  • Likely to be admitted to the Royal Hallamshire Hospital for at least 7 days.

You may not qualify if:

  • Haemorrhagic stroke.
  • \<1 day or \>7 days after onset of stroke symptoms.
  • Clinically unstable, assessed by stroke physician.
  • Disability preventing unipedal cycling.
  • New York Heart Failure Classification stage III/IV.
  • Terminal illness (life expectancy \<6 months).
  • Resting blood pressure \>180/110 mmHg.
  • Uncontrolled arrhythmia causing symptoms or haemodynamic compromise.
  • Unstable angina.
  • Uncontrolled diabetes mellitus.
  • Acute deep vein thrombosis, pulmonary embolism or pulmonary infection.
  • Already participating in a clinical research trial.
  • Pain during mobilisation of lower-limbs.
  • Lower-limb spasticity or contracture which impairs ability to cycle.

Data Sharing

IPD Sharing
Will share

We will have exclusive access to the data for 24 months after the end date of the study whilst we develop a protocol and grant application, and publish our findings. Data will be accessible before 24 months should these objectives be achieved earlier than expected. Anonymised data will be provided on application rather than be offered open access. A description of the data will be placed on the University open access repository (SHURDA). Data sharing will be subject to an application. No sensitive/personal data will be made available. All external users of our data will be bound by a data sharing agreement between the research team, the University, and the user themselves. Data will be supplied on the condition that their research is non-profit, and that their findings will be published in an open access domain. Data users will not be permitted to share the data with anyone outside of their immediate research team.
