Synergistic Effect of Non-invasive Brain and Spinal Cord Stimulation

The goal of this clinical study is to investigate the potential synergy between non-invasive brain and spinal cord stimulation administered during a cognitive-motor task, in terms of their immediate effects on sensorimotor and cognitive functions after neurological injuries affecting the upper limb (cervical spinal cord injury and stroke). Secondary objectives are to evaluate the relevance of anatomical MRI, functional MRI, and neurophysiological measurements for optimizing and predicting the effects of these different interventions.
