About this trial
In a double-blinded sham-controlled study the effect of patient-tailored transcranial direct current stimulation during rehabilitation training will be examined.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age >18 years
Ischemic stroke confirmed by clinical and imaging criteria
Hemiparesis including reduced upper-extremity function
Location of stroke either cortically involving middle cerebral artery or the anterior cerebral artery circulation or subcortical (involving thalamus, basal ganglia).
Disqualifiers
>50% stenosis of extra- or intracranial artery as well as vascular malformations or aneurisms detected by brain CT-angiography.
Exclusively ischemic stroke in spine, pons, brainstem, medulla or cerebellum.
History of seizures, epilepsy, anxiety, dementia alcohol- or drug abuse.
Prior serious head injury or neurosurgery

Trial outcomes
Primary outcomes
Pilot outcome
Difference in Upper-extremity Fugl-Meyer Assessment (UE-FMA) score at end of treatment. Range 0-66.
Secondary outcomes
Change in upper-extremity function
Difference in change in Action Reach Arm Test (ARAT) score. Range 0-57. High scores mean a better outcome.
Stroke severity
Difference in change in National Health Institutes Stroke Scale (NIHSS). Range 0-42. High scores mean a better outcome.
Stroke disability
Difference in change in Modified Rankin Scale (mRS). Range 0-6. Lower scores mean a better outcome.
ADL performance
Difference in change in Bartel's 20-item Index (BI-20). Range 0-100. Higher scores mean better outcome.
Other outcomes
Brain Derived Neutrotrophic Factor (BDNF) genetic polymorphism
Determination of BDNF genetic variant - either Val66Met variant or wildtype.
Feasibility of intervention
Completion of intervention in the active vs. control group
TMS - motor evoked potential
Determination of existence of a MEP-response by TMS as an indicator of cortico-spinal tract integrity. Prognostic marker of motor recovery.
TMS - Ipsilateral silent period (iSP)
Determination of degree of interhemispheric inhibition unaffected vs. affected hemisphere
