Title: Community-based Rehabilitation Training After Stroke: a Pilot Randomised Controlled Trial
Brief Summary: A pilot study that will evaluate the feasibility and acceptability of procedures to inform the design and delivery of a definitive RCT of ReTrain (which would assess the clinical and cost effectiveness of ReTrain for stroke survivors).


Options:
A: Inclusion Criteria:

* Have been admitted to a hospital unit for stroke rehabilitation
* Within 10 weeks post-stroke
* 19 years or older
* Are experiencing difficulty walking

Exclusion Criteria:

* Requires greater than one person assist for transfer or ambulation
* Have uncontrolled medical condition or another serious medication condition in addition to stroke
* Unable to understand or follow directions
B: Inclusion Criteria:

1. Ischemic or hemorrhagic stroke occurring at least 6 months prior to enrollment
2. Age range from 20 to 90 years
3. MMSE score ≥ 19
4. MoCA\<26
5. Self- or informant-reported memory or cognitive complaints or CDR scale ≤ 0.5
6. Able to follow the study instruction
7. Adequate cardiopulmonary function to perform aerobic exercise
8. Able to walk with or without assistive devices

Exclusion Criteria:

1. Unstable medical history (e.g., recent myocardial infarction) that might limit participation
2. Concomitant with other neurological disorders (e.g., Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis)
3. Current participation in another interventional trial
C: Inclusion Criteria:

* Primary clinical diagnosis of stroke (assessed by referring clinician/GP records)
* \>1 month (but no upper limit) since discharge from NHS physical rehabilitation services at randomisation
* Able to walk independently indoors with or without mobility aids, but has self-reported difficulty or requires help on stairs, slopes or uneven surfaces (assessed by recruiting team using standard tools)
* Willingness to be randomised to either control or ReTrain (and attend the training venue)
* Cognitive capacity and communication ability sufficient to participate in the study (assessed by recruiting team using standard tools).24 NB: Criterion (3) has been selected pragmatically to maximise eligibility while ensuring participants have a mobility deficit that could be addressed by the intervention. Eligible people with aphasia will not be excluded.

Exclusion Criteria:

* \<18 years old
* Contraindications to moderate to vigorous physical activity. Used in GP screening assessment form. (Adapted from ACSM guidelines 25) Contraindications include:

  * Acute or uncontrolled heart failure

  * Symptomatic severe aortic stenosis
  * Current deep vein thrombosis, pulmonary embolus or pulmonary infarction
  * Acute myocarditis or pericarditis
  * Suspected or known dissecting aneurysm
  * Unstable / uncontrolled blood pressure
  * Systolic blood pressure \> 160
  * Diastolic blood pressure \> 100
  * Acute systemic infection
  * Uncontrolled diabetes
D: Inclusion Criteria:

* diagnosed with stroke
* 18 years of age or older
* community dwelling
* able to walk 10m independently, with or without an assistive device
