Gedetailleerde beschrijving
Over 3 consecutive days, healthy individuals, acute and chronic stroke patients (1) will be evaluated and (2) will train on the neurorehabiliation robot REAplan® and Dextrain® device.
They will practice a task on the robot REAplan® (unimanual or bimanual version), requiring movements with the affected arm (unimanual version) and complex, coordinated movements with both arms (bimanual version). They will practice another task on the Dextrain® device, also in unimanual and bimanual version.
In addition, several standardized clinical scales and tests will be used to evaluate overall motor-sensory-cognitive functions (clinical tests, questionnaires, ...)
