Study of Brain-spinal Cord Neural Connectivity in Spasticity
Little is known about the peripheral and central mechanisms of action of selective dorsal rhizotomy surgery for the treatment of spasticity. A better understanding of these mechanisms will enable us to improve the surgical procedure. This will require cortico-medullo-radiculo-muscular recordings never before performed and published in the literature, and the identification of variations in connectivity correlated with the clinic.
