 We will include patients with thromboembolic non-hemorrhagic hemispheric lesions at least 6 months after the stroke. We will choose patients who initially had a severe motor paresis below MRC grade 2, which subsequently recovered to the point that they have a residual motor deficit but can perform the required tasks. Assessment of the initial functional state will be taken either from patient report or medical records. As a control group, we will include age- and gender matched healthy volunteers with matched non-dominantdominant hand to the affected hand of the stroke patients.
