Title: N/A
Brief Summary: The purpose of this study is to determine whether tDCS in combination with motor training can improve hand and arm function in stroke patients.


Options:
A: Inclusion Criteria:

* Stroke patients onset \> 6 months
* First ever stroke
* Decreased hand and arm function
* Mini Mental State Examination (\>24)

Exclusion Criteria:

* Depression
* Pregnancy
* Alcohol abuse
* Aneurysm clips
* Pacemaker
* Neurostimulator
* Implemented defibrillator
* Magnetically activated implant or device
* implemented pump
* Spinal cord simulator
* Implemented hearing aid
* Artificial or prosthetic limb
* Metal parts in the body
* Any external or internal metal
* Artificial heart valve
* Other implants
* History of brain surgery
* Migraine
* Family history of Epilepsy
B: 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
  * Unstable or uncontrolled angina
  * Uncontrolled cardiac dysrhythmia causing symptoms or haemodynamic compromise
  * 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
C: Inclusion Criteria:

* Clinical diagnosis of acute stroke
* Able to walk 10m independently
* High risk of falling

Exclusion Criteria:

* Severe functional limitations
* Cognitive impairment
D: Inclusion Criteria:

1. Age over 21 years
2. Ischemic stroke confirmed by CT or MRI within the previous 6 weeks
3. No history of prior ischemic or hemorrhagic stroke with associated motor deficits (prior stroke with no motor symptoms is allowed)
4. Residual unilateral arm weakness with Fugl-Meyer Upper Extremity (FM-UE) score 6-40 at time of enrollment.
5. Ability to give informed consent and understand the tasks involved.

Exclusion Criteria:

1. Space-occupying hemorrhagic transformation or associated intracranial hemorrhage.
2. Arm impairment that is too severe or too mild on day of baseline testing just prior to beginning of the study intervention.
3. Recent botox injection to upper limb or planned botox injection over the course of the 7-month study duration.
4. Cognitive impairment, with score on Montreal Cognitive Assessment (MoCA) ≤ 20.
5. History of physical or neurological condition that interferes with study procedures or assessment of motor function (e.g. severe arthritis, severe neuropathy, Parkinson's disease).
6. Inability to sit in a chair and perform upper limb exercises for one hour at a time.
7. Participation in another upper extremity rehabilitative therapy study during the study period.
8. Terminal illness
9. Social and/or personal circumstances that interfere with ability to return for therapy sessions and follow up assessments.
