fNIRS Study of Effort-dependent Brain Activations During Pointing Movements of the Upper Limb in Post-stroke Patients and Healthy Subjects

Recording of cerebral hemodynamic with fNIRS during upper limb pointing movements with a robotic device in three conditions: movements with robot assistance, movements without robot assistance and movements with robot resistance. Each subject are recorded during 6 trials for each condition (18 trials). The order is counterbalanced among the subjects.
