To test the capacity of healthy and chronic stroke patients to learn and retain a complex bimanual motor skill, trained on the neurorehabilitation robot REAplan (R) (bimanual version).
Over 3 consecutive days, healthy individuals and chronic stroke patients (1) will be evaluated and (2) will train on the neurorehabilitation robot REAplan(R). They will practice several tasks on the robot REAplan (R) (bimanual version), requiring either movements with the affected arm (unimanual tasks) and complex, coordinated movements with both arms (bimanual tasks). In addition, several "classical" clinical scales and tests will be used to evaluate overall motor-sensory-cognitive functions (clinical tests, questionnaires, ...).

Visual Analog Scale for fatigue (VAS fatigue)
Visual Analog Scale to evaluate fatigue = a psychometric response scale which can be used in questionnaires. It is a measurement instrument for subjective characteristics or attitudes that cannot be directly measured. When responding to a VAS item, respondents specify their level of agreement to a statement by indicating a position along a continuous line between two end-points. Range : 0- 10.
Time frame: change between baseline (Day 1) and after training (Day 3)
