About this trial

This study aims to investigate whether the improvements achieved through motor skill learning (MSkL) with the ipsilesional upper limb (UL) are transferred to the contralesional UL during the (sub)acute stroke phase, and to identify the neural substrates underlying this inter-limb transfer. To achieve this, healthy individuals, acute and chronic stroke patients will perform proximal and distal MSkL tasks using serious games implemented on robotic devices. This will be complemented by behavioural assessments and multimodal MRI.
