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

Background: Following a stroke, as part of neurorehabilitation, the intensity of effort is important to promote neural changes and stimulate motor recovery. There are few studies concerning the cortical activity involved at different levels of intensity during upper limb motor training. Objective: To investigate cortex activation while walking an exoskeleton with 4 levels of guidance force in healthy controls.
